How to protect strawberries from frost in spring. When to plant strawberries

After harvesting and the end of intensive vegetative growth, strawberries continue to actively absorb nutrients. They are needed for the autumn growth of the root system, for the formation flower buds. Plants accumulate nutrients for next year's harvest.

Winter preparation

During this period, the main attention should be paid to top dressing, which must be combined with watering.

For what? You ask, because the strawberry harvest has already been harvested for her, and it’s time for you to rest.

Well-groomed strawberries, grown without violations of agricultural technology, have high winter hardiness. Strong plants overwinter better.

You can feed strawberries with organic fertilizers (mullein 1:5, bird droppings 1:10, ash), mineral fertilizers(phosphorus and potassium). These fertilizers are applied at the grooves made on both sides of the strawberry row at a distance of 10 cm from the plants.

After harvesting, foliar top dressing with microelements is also useful.

After the final collection of berries, you need to mow the foliage, but so that the apical buds remain. Mowing is necessary in order to rid the strawberry bed of white and gray rot.

After mowing and harvesting dry foliage from the bed, we water the strawberries abundantly, and after that we loosen the soil.

Strawberry (wild strawberry) is a moisture-loving plant. Therefore, for her, soil moisture is a decisive factor in normal growth and development. If the strawberry bushes do not have enough moisture, they will be inconspicuous: the size of the leaves, the number of horns, antennae and peduncles decreases. There will be fewer flowers, some of the berries will be underdeveloped. The result is a small harvest.

The number of irrigations and their timing in the post-harvest period depend on weather conditions. And the norm - from the amount of moisture in the soil.

After the strawberry (strawberry) completes fruiting, a new one grows under the old roots. You probably noticed that from year to year, growing, the rhizome rises up, and at this very time the soil under it compacts and settles. New roots, not finding food, dry out and die. And this will further affect the quality and quantity of the crop. And so that this does not happen every year at the end of summer, the bushes need to be sprinkled with earth. This improves the nutrition of the plant, and promotes better education flower buds.

Excess tendrils that are not needed for reproduction must be removed, because they take moisture and nutrients from the plant.

If strawberry seedlings were not planted before mid-September, then there is no need to do this, because they will not have time to take root well, and without special protection they may die. Intensive growth of strawberries falls on evening time, and after 15 cold nights and evenings already begin.

We finish fertilizing and loosening the strawberry soil until mid-August, in autumn period it is very important not to disturb the root system. Leave the emerging weeds until next spring. And if you have carried out soil mulching, and it must be carried out, then they are unlikely to be. For mulching, you can use humus, dry woody leaves, straw, peat, reeds, etc.

In October, we spud strawberry roots, cover with peat, humus (we do not completely cover the plants, but only the root zone).

Planting strawberries successfully withstand low temperatures in the presence of snow cover. The exception here is some varieties that are afraid of frost.

In addition, you need to grow zoned varieties, those that suit your region.

If there is no snow, at a temperature below minus 12 - 16 degrees. The bushes partially freeze or even die. Therefore, the area where strawberries grow must be protected (naturally or artificially) from cold northern winds. But, of course, this is not enough.

Be sure to take care of snow retention (tree branches, corn stalks, etc.). In winter, try to move as much snow as possible from another place to planting strawberries.

How and how to cover strawberries (strawberries)

Under the snow cover with a layer of 25 - 40 cm, strawberries hibernate well. If there is no snow at all, and the temperature is below 8 degrees. C, then plantings must be covered with straw manure, humus, sawdust, straw, leaves or other light covering material with a layer of 6 to 10 cm.

There is a very important point here: we cover the strawberries when the soil is completely frozen - otherwise it may splatter.

In the spring, we take the covering material outside the site or move it to the aisles.

In no case should one be indifferent to the protection of plants in winter, because this will lead to freezing not only of flower buds, but also to freezing of fruit-bearing bushes.

After the onset of frost, a bed with strawberries (strawberries) can be covered with agrofiber - a modern synthetic non-woven, environmentally friendly pure material. Such a shelter will help the plantings to winter and will serve you for more than one year.

Protecting strawberries from spring frosts

It often happens that strawberries suffer from frost during the flowering period.

When the temperature drops to minus 1 deg. With about 5 - 8% of the flowers die. At 3 deg. frost - from 9 to 25% or more.

What happens on the affected flowers.

First, the pestle dies, so you don’t have to wait for the ovary. It happens in the spring, the flowers open, and bloom well. But this is at first glance. If you take a good look at them, you will notice that in the central part of the bait of the pestle have turned black. So they are dead. It happens that some part of the pistils

persists, in such cases underdeveloped deformed fruits are obtained.

What determines the level of injury?

The answer is unequivocal - from the level of development of the plant. Strong bushes, correspondingly more resistant to natural phenomena. And weak bushes often do not withstand minor cold snaps. Frosts down to minus 3 degrees. With damage not only buds, flowers, but even leaves.

Particularly affected by frosts are not well-groomed thickened plantings of strawberries.

How to deal with frost?

In the fight against frost, sprinkling of plantings gives a good effect.

Previously used smoke plantings of strawberries.

Nowadays the most effective method- covering with agrofibre. If frosts continue for several days: cover in the evening, remove in the morning. This is done so that the bees pollinate the flowers well.

Hardworking bushes bear fruit from early spring to late autumn. Repair varieties until the very cold large berries. In autumn, they slowly ripen in the dim sun, are no longer so juicy and fragrant, but the bushes are strewn with sweet berries. The last few days left before the frosts, and in some places the first frosts have already bound the earth. To keep strawberry and strawberry bushes healthy until spring, they need to be properly prepared for wintering - you will find recommendations in this article.

How to prepare strawberries for wintering

There is one obligatory rule - it is possible to prepare berry bushes for winter only after flowers and ovaries of berries cease to appear on them. For better preservation of the bushes in winter, it is necessary to carry out a set of works on pruning the leaves of strawberries or strawberries, carrying out autumn dressings special formulations and devices for direct winter shelter.

Pruning bushes

Experts argue which is better: to cut the leaves from strawberry bushes in the winter or not to cut them. There are quite a few reasons to do this operation in the fall:

In the old leaves, pests overwinter, which in the spring will quickly populate the plants in the garden.
Leaves - a place of accumulation of pathogens infectious diseases.
When in contact with wet soil, the leaves quickly rot, becoming dangerous factor infection with rot of the whole plant.
Plants with minimal leaves are easier to cover.

Along with this, there are good reasons not to prune strawberry bushes:

When pruning leaves, many wounds remain on the bushes, especially when removing a large number green mass. Wound surfaces serve as entry gates for infections.
With the maximum removal of leaves, the strawberry bush is under severe stress, which is not very good in preparation for wintering. In addition, the plant will try to urgently restore leaf cover, will spend the last of his strength on growing new foliage.
At inaccurate removal leaves, the heart of the bush is often damaged, such a plant may die in winter.

A very interesting option is the partial pruning of a strawberry bush, when the oldest and most damaged leaves are removed. Tearing them off the bush by hand is not recommended; it is best to carefully cut the cuttings of the leaves with sharp scissors that do not crumple the leaf tissue. Sick leaves are burned, otherwise next year an infectious focus may occur on a berry plantation.

Sometimes rooted mustaches remain next to the bushes. You can not remove young plants from the garden until spring, when they are transplanted into a separate bed. Overwintered rooted rosettes are more resistant to bad weather, bloom faster and give a full harvest.

Watering before wintering

Should not go into the winter sluggish, so the beds are well watered several times before preparing the plants for shelter. Watering is carried out in advance, in early September or even at the end of August, depending on the weather. If the beginning of autumn turned out to be rainy, watering is optional.

Bush feeding

A rich harvest has depleted the berry bushes, so strawberries need to be fed before wintering. nutrients. This operation is performed after partial removal of the leaves, using organic fertilizers. Suitable bird and cow manure, ash, compost diluted in water.

The table shows the proportions of the components for the preparation of a nutritious infusion:

Name	Breeding proportions	Application
bird droppings	1:10, where 10 is water in liters	Bird droppings is a very useful fertilizer, it is soaked in water, insisted for 2 days and poured under strawberry bushes, trying not to get on the leaves. It is best not to pour the solution close to the center of the bush.
	1:1:10, where 1 is mullein; one- charcoal or ash, 10-water	To prepare the infusion, take rotted mullein and one part of the ash. Insist for 2-3 days, watered with a row-spacing solution.
	150 g per 1m2	Scatter dry powder on the bed

Fertilized plants tolerate winter better, bloom en masse in spring ahead of schedule.

Mulching

In September, you need to mulch the beds and row spacing. If at the end of August the strawberry beds were not loosened, this operation is not necessary, as this can damage the roots, which will result in unnecessary problems for the wintering plant. You can lightly roll the lower part of the bush with earth, especially if the roots are exposed. It is best to mulch the soil with straw, spruce branches, fallen leaves, corn stalks.

The litter is laid out on the ground, trying to distribute it evenly.

IN northern regions where harsh winters, you can cover the beds with strawberries more carefully. With the onset of frost, a special film or lutrasil is laid on top of the beds, over which the fallen snow is thrown. Under such a shelter, berry bushes are safe, just remember to remove the film in early spring, otherwise the landings can vyprevat.

Strawberries are not so hard to care for - simple events carried out on time will allow you to harvest next year the richest harvest delicious and useful berries d.

Spring frosts can cause great damage to a strawberry plantation, which cannot destroy the entire strawberry bush, but will harm the crop. Spring frosts affect flowers and fruit ovaries in strawberries, as a result of which a black dot appears in the middle of the flower and there will no longer be a full-fledged berry from it or it will be underdeveloped.

IN spring period, even if the weather forecast reports positive night temperatures, on a cloudless night, when the air is dry and there is no wind, there may be “frosts on the soil”, while drizzle appears at the level of strawberry growth.

If your strawberry occupies several beds, then the most in a simple way protection will covered with strawberry covering material or even put a paper cap on each bush. And if the plantation occupies several acres, then sprinklers should be used to protect strawberries from frost.

Strawberry protection by fine sprinkling It is based on the fact that when water freezes, heat is released and thus the temperature rises. The resulting ice crust does not perform protective functions. Water, constantly freezing on a strawberry bush, raises the temperature around it and does not allow it to fall below critical.

Frost protection sprinkler may consist of ordinary sprinklers with a nozzle that forms fine droplets.

The amount of water used for protection depends on temperature and wind speed. It is considered that water flow for protective sprinkler providing 2mm of precipitation per hour is sufficient for protection down to -4.4 °C in the absence of wind.

If the ice on strawberries is milky white, then you need to increase the water consumption.

At wind speeds over 16 km/h or at temperatures below -6.7 °C, sprinkler irrigation can bring more harm than good due to rapid freezing.

For the moment start irrigation psychrometer readings can be used. Protective irrigation should be started before reaching the critical wet-bulb temperature. The critical temperature for open flowers is -1.1 °C, and for berries - 2.2 °C.

Irrigation can be stopped when the ice on the plant begins to melt, usually after sunrise.

Christina was interested in how to protect strawberries from recurrent frosts in the spring? Let's try to answer and save so wonderful plant from death.

Rules for preserving strawberries

Every spring we face frost. They do not always harm plants and shrubs, but in the case of late frosts that occur in the second half of May, significant damage can be incurred. It is frosts that can cause a low yield in the future.

In early spring, only the tips of the leaves freeze slightly in plants, which does not affect them much. Strawberries usually recover well after that. Especially if a frost-resistant strawberry variety was chosen.

During return frosts, the plant can also be saved if you learned about their onset in advance from the weather forecast. Know that when you feel a cold snap, more severe frosts should be expected in the evening! How to deal with the problem?
Most The best way to protect strawberries is watering. This technique is called sprinkling. The plants themselves should not be watered, it is enough to water only the soil.

In order to protect strawberries from freezing, it is enough to raise the temperature by only a couple of degrees, and the plant will not freeze. Sprinkling is applied only when the temperature drops below 0 degrees, and continues until the frost stops.

Other ways to keep warm

How else to save the future harvest

Newspapers and film will also help to save plants. This best option. As soon as frosts have come, you need to cover the strawberries on top with a film. If the weather is calm, then you do not need to fix it with anything. The cover will keep the soil warm. If you also water the soil before this, the effect will be much better.

Using smoke or fumigation, you can also save strawberries. This method is characterized by smoke, which surrounds the plants with a thermal curtain. By burning garbage, brushwood, dry branches or whatever is at hand, you can raise the temperature environment. Bonfires are lit at a temperature of 0 degrees. Peat gives the most smoke, which more fully envelops the garden. The presented method is good in that it gives the plants additional heat. However, one should always remember that fire should be handled very carefully.

Most affected by recurrent frosts root system. And the strawberry itself, as a species, is the least resistant to cold. But at proper care behind it, during return frosts, you don’t have to worry about the fact that in the near future the harvest will be bad, and you definitely won’t lose the plants.

Strawberries are a berry that is very afraid of frost. Afraid mostly when it blooms! If the color falls under the frost, there will be no strawberries! You need to follow the weather forecast and if frost is transmitted, warm the strawberries. It could be polyethylene film- from old booths, greenhouses. Perhaps this is the best remedy! You can cover with straw, but it will not save the whole color.

I agree with the previous comment that only the strawberry flower is afraid of frost (there will be no more berries if the flower freezes). But to cover with a film is not the most suitable means of insulation, where the film touches the flower, it will definitely freeze. You can burn fires around the perimeter, the smoke will spread over the strawberries and thus, as it were, wrap them up from the frost. Probably best with straw.

Astrakhan tomatoes ripen remarkably lying on the ground, but you should not repeat this experience in the Moscow region. Our tomatoes need support, support, a garter. My neighbors use all sorts of pegs, garters, loops, ready-made plant supports, and mesh fences. Each method of fixing the plant in an upright position has its own advantages and " side effects". I'll tell you how I place tomato bushes on trellises, and what comes of it.

Every summer resident knows that plants need nitrogen, phosphorus and potassium for full development. These are the three main macronutrients, the deficiency of which significantly affects appearance and yield of plants, and in advanced cases can lead to their death. But at the same time, not everyone understands the importance of other macro- and microelements for plant health. And they are important not only in themselves, but also for the effective absorption of the same nitrogen, phosphorus and potassium.

Garden strawberries, or strawberries, as we used to call them, are one of the early fragrant berries that summer generously endows us with. How we rejoice in this harvest! In order for the "berry boom" to repeat every year, we need to take care of the care of the berry bushes in the summer (after the end of fruiting). The laying of flower buds, from which ovaries will form in spring, and berries in summer, begins approximately 30 days after the end of fruiting.

Many decorative and fruit crops, except for drought-resistant ones, suffer from the scorching sun, and conifers in the winter-spring period - from sunlight, enhanced by reflection from snow. In this article we will talk about a unique preparation for protecting plants from sunburn and droughts - Sunshet Agrosuccess. The problem is relevant for most regions of Russia. In February and early March, the sun's rays become more active, and the plants are not yet ready for new conditions.

“Each vegetable has its own time”, and each plant has its own optimal time for landing. Anyone who has experienced planting is well aware that the hot season for planting is spring and autumn. This is due to several factors: in spring, the plants have not yet started to grow rapidly, there is no sweltering heat, and precipitation often falls. However, no matter how hard we try, circumstances often develop in such a way that landings have to be carried out at the very height of summer.
