Harvesting and storing

How Does Weather Affect Storage Ability?

Beets are a relatively cold-hardy crop, but they have their "weak spots." The key rule is: harvest beets before the onset of sustained autumn frosts. Why is this so important?

Table beet roots, unlike carrots or parsley, are quite sensitive to subzero temperatures. If a root is even slightly frozen (at –1…–2 °C), its tissues are damaged, and it will quickly rot during storage (Nonnecke, 1989; Karataev and Sovetkina, 1984). Even slight freezing makes beets unfit for long-term storage—they become soft, lose turgor, and develop rot.

On the other hand, harvesting too early (in warm weather) is also undesirable. Roots continue to accumulate sugars and dry matter right up to harvest, and if dug up too early, they will be juicy but "watery" and will quickly wilt in storage (Autko et al., 2012). Additionally, with early harvesting, the beet skin is not yet strong enough, is easily damaged, which reduces disease resistance.

Optimal Harvest Time

In most regions of Russia and countries with a temperate climate, the best time to harvest beets is late September to the first half of October, when the average daily air temperature drops to +4…+6 °C, but there have been no frosts yet (Nonnecke, 1989; Torikov and Sychev, 2018). It is at this temperature that root growth practically ceases, but they are not yet damaged by cold.

Follow the long-term weather forecast. Harvest beets on a dry, clear day when the soil is sufficiently loose but not too dry. Wet soil makes digging difficult (dirt sticks to the roots) and increases the risk of mechanical damage. In rainy weather, roots are harder to clean of soil, and high humidity promotes the development of rots even before storage (Khan et al., 2026).

What if frost is already approaching?

If early frosts are forecast and the beets have not yet reached the desired size, you can speed up maturation. Stop watering 2–3 weeks before the intended harvest—this will increase sugar concentration and strengthen the skin. You can also carefully trim some of the leaves to reduce evaporation and accelerate the flow of nutrients to the root.

But if frost does occur and you haven't harvested the crop, there is a chance to save the roots. Dig them up immediately after the soil thaws, but do not expect them to store long—such beets should be processed first (Karataev and Sovetkina, 1984).

Regional Features

In southern regions, harvesting is often done later, right up to November, when warm, dry days prevail. In northern regions (Siberia, the Urals, the Non-Black Earth region), harvesting must be completed by the end of September to avoid frost. In Belarus and central Russia, the traditional dates are from September 20 to October 10 (Autko et al., 2012).

If you live in a region with an unstable climate (frequent thaws and cold snaps), it is better to harvest beets a week earlier than to risk freezing. A partial loss in yield due to under-ripeness is less critical than the total loss of roots from rot during storage.

What to Do with the Tops Before Harvest?

1–2 weeks before the intended harvest, you can lightly trim the tops, leaving petioles 8–10 cm long. This helps "switch" the plant to channel nutrients into the root and improves its maturation. However, cutting the leaves too much in advance is not advisable—it may weaken the plant and reduce the accumulation of dry matter (Nonnecke, 1989).

Next chapter—"How to Dig Beets Correctly?"—we will cover practical techniques, tools, and the main rule: how to avoid damaging roots during digging. Would you like to continue?

Which Tool to Use?

The choice of tool depends on the soil type and plot size. The main rule: do not pull beets out by the tops! This almost always leads to the root breaking or damage to the neck, which is detrimental to storage (Nonnecke, 1989).

• On light sandy and sandy loam soils, you can use garden forks or a flat-blade spade. Forks are preferable—they cut roots less if they accidentally hit them. Carefully dig the root from the side, slightly lift the soil layer, and remove the beet, holding it by the base of the tops with your hand.

• On heavy clay and loamy soils (especially after rain), it is better to use a spade with a pointed end or a root lifter (a special hook available at garden stores). A pointed spade penetrates dense soil more easily. Important: dig the root at a distance of 5–7 cm from it, so as not to damage the lateral roots or cut the skin.

• For large areas (for small farmers), you can use a mounted root lifter or a potato digger with adjustable depth. However, with machine harvesting, the risk of damage is higher, so equipment setup must be especially thorough (Autko et al., 2012).

Digging Technique: Step by Step

1. Check soil moisture. If the soil is too dry and hard, lightly moisten it the day before harvest (if possible)—this will make extraction easier. But do not overdo it: wet mud will stick to the roots and complicate cleaning (Khan et al., 2026). Ideally, the soil should be slightly moist but not sticky to the hands.

2. Step back from the root. Insert the fork or spade vertically at a distance of 5–7 cm from the root to cut the lateral roots, but not damage the root itself (Nonnecke, 1989).

3. Lift the soil layer. Press lightly on the tool handle to lift the root along with a clod of soil. Do not pull sharply—it is better to make several careful movements, gradually freeing the root.

4. Remove the beet. Grasp the base of the tops (not the leaves!) with your hand and, slightly turning, pull the root from the soil. Shake off large clods of soil, but do not knock roots against each other—this causes micro-cracks and bruises (Balashev and Zeman, 1981).

5. Spread out for drying. Immediately after digging, spread the beets on the bed or on a mat in a single layer so they can air out and dry for 2–4 hours. Do not leave the roots in direct sunlight for long—they may lose turgor and become limp (Karataev and Sovetkina, 1984).

What Absolutely Must Not Be Done

• Do not pull beets out by the tops. Even if the soil is loose, a jerk can damage the neck and the attachment point of the petioles. A damaged neck is a direct path to rot during storage (Nonnecke, 1989).

• Do not cut the tops immediately after digging. Leave petioles 2–3 cm long so that juice does not leak from the root and it does not wilt before trimming. It is better to cut the tops after a short drying, when the roots have dried out a little (Autko et al., 2012). We will cover this in detail in the next chapter.

• Do not shake off soil by hitting the root against a spade or against each other. This causes micro-traumas to the skin, which turn into rotting sites during storage. It is better to gently shake off the soil with your hands or a soft brush (Khan et al., 2026).

• Do not leave harvested roots overnight outdoors if frost is forecast. If the night is expected to get cold down to 0 °C, immediately move the beets under cover or at least cover them with agrofabric.

Field Sorting

While the roots are drying, conduct a primary sorting. Set aside:

• Damaged roots — with cracks, cuts, deep scratches. These can be processed first (for cooking or preserving).

• Frost-damaged roots — they will become soft and unfit for storage.

• Overgrown and misshapen — large roots with coarse skin and fibrous flesh are also unsuitable for long-term storage (Nonnecke, 1989).

Select quality, healthy roots for winter storage.

Now that the beets are dug up and sorted, the next important step is proper trimming of the tops. Shall we do it? Let's move on to Chapter 4.

Why Trim the Tops?

The tops are living, actively breathing leaves. Even after harvesting, they continue to evaporate moisture, "pulling" it from the root. If the leaves are left intact, beets quickly lose turgor, become limp, shriveled, lose weight and flavor (Nonnecke, 1989). In addition, pathogens can enter the root through long petioles, and the leaves themselves quickly rot during storage and become a source of infection for neighboring roots.

Trimming the tops solves several problems at once:

• Stops moisture loss through evaporation.
• Removes a source of infection — fungal spores and bacteria often persist on leaves and petioles.
• Prevents sprouting — without leaves and buds, the root does not waste reserves on growing new shoots (Karataev and Sovetkina, 1984).

When Is the Best Time to Trim the Tops?

Many gardeners cut the leaves immediately after harvesting, which is a mistake. The optimal sequence is as follows:

1. Let the roots dry a little. After harvesting, leave the beets on the bed for 2–4 hours (in dry weather) or under a shelter so the skin dries slightly and the soil becomes easier to brush off. Immediately after harvesting, the petioles are still very juicy, and cutting may release a lot of sap—this weakens the root (Autko et al., 2012). After a little drying, less sap is released, and the cut site heals faster.

2. Remove the tops on the day of harvest. Do not postpone trimming until the next day: the leaves will continue to evaporate moisture all this time, and the roots will lose some of their weight and juiciness. Optimally, trim on the same day, a few hours after digging (Nonnecke, 1989).

3. Do not trim tops in rainy weather — moisture on the cuts slows down healing and promotes rot development. If the weather does not allow drying the roots, trimming should still be done, but then the roots must be thoroughly dried in a dry, ventilated room (Khan et al., 2026).

How to Properly Trim the Tops: Step-by-Step Instructions

1. Use a sharp tool. Use a sharp knife, pruners, or garden shears. A blunt tool crushes and tears tissues, which heals worse. The blade should be clean—wipe it with alcohol or a strong manganese solution to avoid introducing infection (Torikov and Sychev, 2018).

2. Do not break off the leaves by hand! Breaking leaves leaves ragged wounds that take a long time to heal and are open gates for rot. Only cutting is acceptable.

3. Leave a stub. Cut the leaves, leaving petioles about 1–2 cm long above the root head (Nonnecke, 1989; Balashev and Zeman, 1981). Do not cut "flush" with the head—this damages the apical bud and opens access for bacteria into the root tissues. And do not leave petioles too long (more than 3–4 cm)—they will dry out and can serve as a bridge for infection.

4. Do not cut roots. Thin lateral roots that grow from the root do not need to be removed specifically. They will dry out and fall off on their own. It is important not to damage the root itself in the lower part.

5. Do not soak or wash roots before trimming. Beets are washed immediately before use, not before storage. Washing breaks the protective layer of the skin and shortens the storage period (Khan et al., 2026).

What Not to Do

• Do not trim the tops in advance, before digging. Some gardeners cut the leaves a week before harvest to let the roots "ripen." This is risky: wounds may rot, and weakened plants are less able to withstand storage. It is better not to do this (Nonnecke, 1989).

• Do not twist or break off the petioles. This also leads to uneven tissue tearing and poor healing.

• Do not trim the tops from roots that you plan to leave for seed production (for mother plants). Their petioles are left 2–3 cm long, but the storage of mother plants has its own specifics, and this is not used for ordinary harvests (Balashev and Zeman, 1981).

What to Do with the Cut Tops?

Do not throw the tops into the compost heap near the storage facility—they can be a source of spores of pathogenic fungi (e.g., cercosporiosis and phomosis). It is better to bury them in a compost pit, away from the garden, or use them as green manure (siderat) on a separate plot (Autko et al., 2012). Beet tops are also edible—they are used for cooking borscht, salads, and stuffed cabbage rolls.

Now that the tops are properly trimmed, we can move on to preparing the beets for storage: drying, cooling, sorting, and storing. Would you like to know how to prepare beets for storage? That is the next chapter.

Drying: Why and for How Long?

Immediately after trimming the tops, moisture remains on the surface of the roots—both from the soil and from the sap that came out at the cut sites. If damp roots are stored, ideal conditions are created for the development of mold and bacterial rots (Nonnecke, 1989; Karataev and Sovetkina, 1984).

How to dry beets properly:

1. Initial air drying. After digging and trimming the tops, spread the roots in a single layer in a dry, well-ventilated place protected from rain and direct sunlight. A canopy, shed, or garage with open doors are excellent options. Direct sunlight causes overheating and moisture loss, which reduces turgor and accelerates wilting (Nonnecke, 1989). Duration—from a few hours to 1–2 days, depending on the weather and root moisture. Aim for the root surface to be dry to the touch, and the cut site on the tops to be dry and slightly "sealed" (Khan et al., 2026).

2. In rainy weather. If harvesting took place in wet weather and there is a lot of dirt on the roots, they must be thoroughly dried indoors with good ventilation. Spread the beets on slatted shelves or on clean, dry bedding (straw, burlap) so that the roots do not touch each other. Turn them over periodically for even drying. Moisture on the surface must evaporate completely—this is the most important factor for preventing rot during storage (Autko et al., 2012).

3. Important! Do not over-dry the beets. If the roots become limp and shriveled—they will lose marketable appearance and juiciness, and also become more vulnerable to disease. The optimal state is firm, elastic, but dry-surfaced roots (Nonnecke, 1989).

Pre-cooling: Why Is It Important?

After drying, beets must be cooled to storage temperature. This is a critical step, especially if the crop was harvested in warm weather (Nonnecke, 1989).

• Why it is needed. After harvest, roots continue to "breathe"—consume oxygen and release heat, carbon dioxide, and moisture. In a warm pile, this process is very intense, which can lead to overheating, increased respiration, sugar loss, wilting, and rot development. Rapid cooling to 0–2 °C "damps" these processes and stops the growth of pathogenic microorganisms (Khan et al., 2026; Nonnecke, 1989).

• How to cool. If you have a cellar or basement with a temperature around 0 °C, simply place the dried beets there for a day or two so they cool gradually. If the storage room is warm, spread the roots in a thin layer in the coolest place available (for example, on a veranda or in a hallway). The main thing is to avoid sharp temperature fluctuations and not leave the beets in a warm room for long (Nonnecke, 1989).

Thorough Sorting and Culling—The Basis of Storability

This is the most critical stage of preparation. Take it with all seriousness: one diseased or damaged root in storage can "infect" its neighbors.

Carefully inspect each root and set aside for storage only those that simultaneously meet all the criteria:

Tip: Sorting is conveniently done by spreading the beets on a table or clean bedding. Pick up each root, inspect it from all sides, feel for soft spots. Mercilessly discard damaged and questionable specimens. It is better to preserve a smaller but quality crop than to lose everything.

What to Do with Culled Beets?

Do not throw them away! They have many useful uses:

• For current consumption. The simplest way is to use them for soups, salads, vinaigrettes, borscht.
• For processing. Ferment or pickle them—this is an excellent way to preserve them for the winter.
• For animal feed. If you have domestic animals, peeled or chopped beets will be an excellent vitamin supplement for them.

Preparing the Storage Area

While the beets are drying and cooling, it is time to prepare the place where they will lie all winter.

1. Clean and disinfect the storage area. Before storing the new crop, be sure to remove last year's plant residues, debris, and leftover old roots from the cellar or basement (Karataev and Sovetkina, 1984). Walls and shelves can be disinfected with a lime solution (1–2 kg of quicklime per 10 liters of water) or special agents (Autko et al., 2012). This will help destroy fungal spores and bacteria that may have overwintered in the storage.

2. Check ventilation. The storage area should have good ventilation to avoid stagnant air and excessive humidity (Khan et al., 2026). If ventilation is poor, you can use a fan for periodic airing.

3. Prepare containers. The most convenient for storing beets are:

• Wooden or plastic boxes with gaps between slats for ventilation.
• Nets or bags made of breathable material (natural burlap). In plastic bags, beets "suffocate" and spoil (Autko et al., 2012).
• Bulk storage on shelves or on the floor (in clamps) with interlayers of dry sand, sawdust, peat, or moss. This is an old but very reliable method: sand absorbs excess moisture, prevents wilting, and contact between roots (Nonnecke, 1989; Balashev and Zeman, 1981).

Now your beets are fully ready for long-term storage. All that remains is to create the right conditions for them, which we will discuss in the next chapter.

Shall we continue? The next chapter—"6. Optimal Storage Conditions." We'll cover what temperature and humidity to maintain, the role of ventilation, and how to find that balance so beets neither dry out nor rot.

Storage Physiology: Why It Works

Beets are a living organism, and even after harvest, respiration processes continue in them. They consume oxygen, release carbon dioxide, heat, and moisture, while using up their own reserves—sugars and starch. The goal of proper storage is to slow these processes as much as possible so that the roots remain fresh, juicy, and sweet as long as possible (Nonnecke, 1989; Kader, 2002).

At low temperatures and proper humidity, beet respiration slows down significantly. This is called a state of dormancy. While the root is "sleeping," it does not expend energy on growth, does not sprout, and does not lose turgor. Violation of the conditions brings it out of this state, leading to loss of quality (Karataev and Sovetkina, 1984; Autko et al., 2012).

Temperature Regime: 0 to +2 °C

The gold standard for storing beets is a temperature from 0 °C to +2 °C. In this range, respiration slows to a minimum, and microbial activity (mold, bacteria) is maximally suppressed (Nonnecke, 1989; Khan et al., 2026).

• Why exactly this? At 0 °C, aging and wilting processes practically stop, but root tissues are not damaged by cold. This is an ideal balance.
• What if the temperature is higher? Already at +4 °C, respiration noticeably accelerates. Roots begin to "slim down"—lose moisture and mass. At +10 °C and above, beets may start sprouting, become flabby, lose sweetness, and may rot (Nonnecke, 1989; Balashev and Zeman, 1981).
• What if the temperature drops below 0 °C? Frost is detrimental to harvested beets. At –1 °C and below, tissues are damaged, the root becomes soft, watery, and begins to rot upon thawing. Such beets cannot be stored (Nonnecke, 1989).

Practical tip: If you do not have a cellar with a stable temperature of 0–2 °C, store beets in the coldest place available (basement, garage, insulated balcony). But make sure the temperature does not drop below zero—in severe frosts, the roots need to be covered.

Humidity: 90–95%—The "Sweet Spot"

The second most important parameter is the relative humidity of the air in the storage. For beets, the optimal humidity is 90–95% (Nonnecke, 1989; Autko et al., 2012).

• Why so high? Beets actively evaporate moisture through the skin. If the air is dry, the root quickly loses water, becomes limp, shriveled, and loses weight. High humidity prevents evaporation, maintaining juiciness and firmness (Kader, 2002).
• Why not 100%? At humidity close to 100%, moisture may condense on the surface of the roots (especially with temperature fluctuations). And droplet moisture is an ideal environment for mold and bacterial rots (Karataev and Sovetkina, 1984). Thus, 90–95% is a balance between preventing wilting and the risk of rot.

How to maintain humidity:

• Use sand. This is an old, reliable, and very effective method. Layer the roots with dry river sand in boxes or directly in clamps. Sand perfectly retains moisture in the microclimate around each root, preventing it from drying out, and at the same time "breathes," preventing condensation (Nonnecke, 1989). It also helps isolate diseased roots from healthy ones if rot does start.
• Use damp sawdust, peat, or sphagnum moss. These materials also retain moisture well and have antiseptic properties (Autko et al., 2012).
• Moisten the air. If you have a basement, you can place open containers of water or periodically sprinkle the floor and walls with water to increase humidity. However, do this moderately to avoid excessive dampness, which could lead to condensation on walls and ceilings.
• Monitor ventilation. Ventilation helps avoid stagnant humid air and condensation. It should be intense enough to remove excess moisture but not so strong as to dry out the air (Khan et al., 2026).

Ventilation: Why Air Exchange Is Important

Good ventilation is not just about a pleasant smell in the basement. It plays a key role in maintaining the microclimate:

1. Removes excess carbon dioxide. Breathing roots release CO₂. In a poorly ventilated room, carbon dioxide accumulates, which can increase respiration and accelerate spoilage (Nonnecke, 1989).

2. Removes excess moisture. Root respiration also releases moisture. If it is not removed, humidity will rise to 100%, leading to condensation and rot development.

3. Prevents air stagnation. Mold spores and bacteria multiply faster in stagnant air, increasing the risk of root diseases (Autko et al., 2012).

How to organize ventilation:

• Natural ventilation—through vents, an exhaust pipe. This is sufficient in small basements, but you need to ensure it works effectively.
• Forced ventilation—using a fan (or even a small computer cooler). This is especially useful in large storage facilities and if air humidity often exceeds the permissible level (Khan et al., 2026).

Storage Methods: Which to Choose?

There are several methods, each with its pros and cons. The choice depends on your conditions and the scale of the harvest.

Recommendation: For gardeners and small farmers, the best option is wooden or plastic boxes with sand. It is reliable, convenient, and allows you to keep the harvest longer.

Monitoring the Condition of the Roots

Even under ideal conditions, periodically check the condition of your beets. At least once a month (especially in late winter), inspect the roots.

• Remove diseased specimens. As soon as you notice signs of rot, mold, softness, or wilting—remove them immediately. Otherwise, you risk losing the entire crop.
• Watch for sprouting. If you notice roots starting to sprout, lower the storage temperature if possible. Sprouting indicates that the beets are "waking up" and starting to spend reserves on growth (Nonnecke, 1989).
• Check the moisture of sand or sawdust. If they have dried out, lightly moisten them to restore optimal humidity.

Now that you know how to create ideal storage conditions, it remains to discuss the most common problems that may arise. In the final chapter, we will discuss "7. Main Storage Problems"—wilting, rots, sprouting, darkening, and how to deal with them. Would you like to finish the article?

1. Wilting and Loss of Turgor (roots become soft, shriveled)

Cause: The main cause is insufficient air humidity in storage (below 85–90%). Roots lose water through evaporation, and their tissues shrink, losing elasticity (Nonnecke, 1989; Kader, 2002). Wilting can also result from too early harvesting (roots did not have time to accumulate enough dry matter) or damage to the skin, through which water evaporates faster (Karataev and Sovetkina, 1984).

How to prevent:

• Maintain air humidity in storage at 90–95% (see previous chapter). Use water containers, moisten sand or sawdust in which the roots are layered.
• Ensure roots are undamaged. Damaged skin evaporates water much faster.

What to do if the problem has already appeared:

• If wilting is minor, you can try to restore turgor by placing the roots in cool water for several hours. However, after such a "bath," they are not suitable for long-term storage—they should be used for food soon.
• If wilting is severe, the roots have already lost marketable appearance and taste. It is better to process them (drying, freezing, canning) or use them for animal feed.

2. Rots (dry, wet, gray, white)

This is the most serious and most common storage problem. Rots are caused by various fungi and bacteria (Phoma betae, Botrytis cinerea, Rhizoctonia solani, etc.) (Autko et al., 2012; Khan et al., 2026). They can manifest in different ways:

• Dry rot (phomosis): hard, dry, grayish-brown spots that gradually deepen into the root, turning the flesh into crumbly material. Often starts at the head or at the site of skin damage (Nonnecke, 1989).
• Wet rot: the root becomes soft, watery, emits an unpleasant odor. Often accompanied by a gray or white coating of mycelium. Spreads quickly to neighboring roots (Karataev and Sovetkina, 1984).
• White and gray rot: a fluffy coating (white or gray) appears on the surface, under which tissues soften and rot. Especially dangerous at high humidity and poor ventilation (Autko et al., 2012).

Causes of rots:

• Mechanical damage. Any scratch, crack, bruise opens the way for infection (Nonnecke, 1989).
• Freezing. Even slight freezing destroys tissues, making them a breeding ground for bacteria and fungi (Nonnecke, 1989).
• Excessive humidity and poor ventilation. Condensation on the surface of roots and stagnant air create ideal conditions for the development of fungi and bacteria (Khan et al., 2026).
• Storing diseased or damaged roots. One diseased root can "infect" the entire crop (Karataev and Sovetkina, 1984).

How to prevent:

• Thorough sorting and culling of all suspicious roots before storage.
• Creating an optimal temperature-humidity regime (0–+2 °C, humidity 90–95%) and good ventilation.
• Using sand or other moisture-retaining material. Sand, among other things, acts as a barrier—it prevents rot from spreading from one root to another if it does start (Nonnecke, 1989).
• In some cases, it is recommended to dust the roots with crushed chalk or wood ash before storage—this creates a thin layer on the surface that dries the skin and prevents infection (Balashev and Zeman, 1981).

What to do if rot is found:

• Immediately remove all affected roots from storage. Do not hesitate—one left source can destroy the entire crop.
• Thoroughly inspect the roots that were near the rot focus. Even if there are no visible signs on them, they may already be infected. It is better to use them for food first, rather than put them back into long-term storage.
• If rot has affected a significant part of the crop, save what can still be saved—process the healthy roots (fermenting, canning, drying, freezing) so they are not wasted (Autko et al., 2012).

3. Sprouting (new leaves appearing from the apical bud)

Cause: Sprouting is a natural process for a biennial plant that tends to grow a root in the first year and produce seeds in the second. In storage, sprouting is triggered if the air temperature stays above +4…+5 °C for a long time. High humidity and even light can also stimulate sprouting (Nonnecke, 1989; Khan et al., 2026). Small roots are more prone to sprouting than large ones, as they have a higher surface-to-volume ratio and respond faster to changes in conditions (Torikov and Sychev, 2018).

How to prevent:

• The main thing is to maintain the temperature in the range of 0–+2 °C. If the temperature starts to rise, the sprouting process will start.
• Store beets in the dark. Light stimulates growth.
• If you notice the first signs of sprouting (small green shoots at the head), lower the storage temperature as much as possible.

What to do if sprouting has begun:

• Break or cut off the shoots. Do this carefully to avoid damaging the root head. The earlier you do this, the less nutrients will be spent on growth.
• Such beets cannot be stored long: they will lose moisture, become flabby, and lose taste. They should be used first (Nonnecke, 1989).
• In late winter—early spring, sprouting is almost inevitable, as the plant internally "prepares" for the new season. By this time, it is advisable to eat or process the remaining harvest (Karataev and Sovetkina, 1984).

4. Darkening of Flesh and Loss of Color

Cause: Darkening of the flesh during storage can be due to several factors. Firstly, it may be a consequence of late harvesting or improper storage conditions, when metabolism is disrupted. Secondly, it may be a physiological disorder—"blackheart" caused by boron deficiency (boron starvation) during the growing season. In this case, dark, almost black, dry spots form in the center of the root (Nonnecke, 1989; Autko et al., 2012).

How to prevent:

• Timely harvesting at optimal times.
• Balanced fertilization, especially micronutrients (boron). If boron deficiency is suspected, foliar feeding with boric acid can be done during the growing season (Nonnecke, 1989).
• Maintaining stable storage conditions (without sharp temperature fluctuations).

What to do if the problem appears:

• Roots with severe darkening are unfit for consumption, as they have a bitter taste and may be harmful. They should be discarded.
• Slight darkening in the center can be cut out, and the remaining part used for food. However, such roots will not store anymore—they need to be processed or eaten immediately.

5. Loss of Sweetness and Deterioration of Taste

Cause: The taste of beets is mainly determined by sugar content. During storage, sugars are consumed in respiration. The intensity of this process directly depends on temperature: the warmer the storage, the faster the root "breathes" and loses sweetness (Kader, 2002; Khan et al., 2026). Taste may also deteriorate due to wilting and accumulation of decomposition products.

How to prevent:

• Low storage temperature (0–+2 °C) is the main way to preserve sweetness.
• Good ventilation helps remove excess carbon dioxide and heat released during respiration.

What to do:

• Unfortunately, it is impossible to restore sweetness to roots that have already lost it. They should simply be used for food as soon as possible, perhaps in dishes where the taste is masked by other ingredients (for example, in borscht).

Prevention Is the Best Cure

The most reliable way to avoid storage problems is to follow all the rules from choosing the variety to storing the harvest:

1. Choose the right varieties. For long-term storage, mid-season and late-maturing varieties are best, such as 'Bordeaux 237', 'Cold-Resistant 19', 'Winter A-474', 'Cornell', 'Egyptian Flat' (Nonnecke, 1989; Autko et al., 2012).

2. Proper agricultural practices. Balanced nutrition, timely watering, and disease control during the growing season make roots healthier and more storable.

3. Careful harvesting. Minimize mechanical damage at all stages: from digging to storage.

4. Thorough preparation. Drying, cooling, sorting, and trimming tops are mandatory steps.

5. Strict control of storage conditions. Regularly check temperature, humidity, and the condition of the roots.

We have covered the full journey—from determining maturity to dealing with storage problems. I hope this guide will help you preserve your beet harvest until spring. If you have any questions or would like us to expand on any section, I will be happy to help!
