How to protect the garden from frost: a review of effective methods

Frosts can kill young, immature plants, so gardeners should take appropriate measures to protect seedlings from frost

During the period of possible frosts seedlings podzimye garden and vegetable crops are vulnerable. The sudden drop in temperature at night can destroy the future harvest. In some regions of the autumn planting are more effective than spring. At the root system will have more time to strengthen, to the spring began early development. Therefore, gardeners have planted young trees, vegetable crops before winter.

Our readers are discussing the topic of protection of autumn plantings from frost. Here is what the participant portal Utiatka: "Good day! When autumn planting the best way to warm in the winter apple seedlings (planted in the fall)? Write about the paper, nylon stockings, plastic bottles, ribbons of non-woven fabrics, even about the insulation for the pipes made of polyethylene foam. Quite confused - that it is better to use "?

We conducted a study of this issue and are willing to share effective ways that are tested and approved by experienced gardeners. See also:

type of frost

To detailed answers to questions from our readers, we must begin by considering types of frost, and their impact on the horticultural culture. Called frost temperature decrease is less than 0 ° C, which occurs during the night and morning time. During the day the air warms up to plus indicators.

In each region, this happens at a certain time. Here is what the participant portal Milena 55: "Friends! With early onset of cold weather and night frosts in the Moscow region there was such question: the upset into the ground a week ago perennials (height greater than 1 m) can damage the cold night (here afraid to -7)? Maybe tree trunks warm somehow, or at night to roll himself seedling cover material? Or leave as is? What do you advise?"

Responding to questions from our readers, we note that the following types of frost:

• Advective. These migration caused by freezing of cold, humid air in the horizontal plane. Such cold come unexpectedly and can be held on the soil surface for a long time.
• Convection. This phenomenon is explained by the laws of physics. Ground stores heat during the day and at night the earth gives it the air. It goes up, and his place is occupied by cold air masses that weigh more. The less heat will accumulate the soil during the day, the more she would give him at night, the more serious the consequences will be for the plants. These frosts occur in calm, clear weather.
• Mixed. They are caused by the action of both unfavorable factors.

Freezing are not weak below -2 ° C to -4 ° strong C., very strong to -8 ° C. Even a slight decrease in temperature may damage immature plants. Therefore, the fall planted just cold-resistant culture.

Less harm reduction in temperature causes non-germinated seedlings. They are under a layer of soil, mulch. Therefore, gardeners, gardeners need to choose the right moment for entering into a ground seeds. When they hatch, frozen partially or completely destroy crops.

Plants need to get ready for winter, hibernate. Sap flow should be stopped, otherwise the water in the tissue will freeze and damage the cell membrane. Because of this, the plant will die.

Effect of frost on the garden crops

Novice gardeners can not decide when to plant trees, vegetable and ornamental plants. Here is what the party forumaAsvetlanaa: "I am very green rookie, this year for the first time generally start ogorodnichat. I want to order in the autumn seedlings of different fruit, prikopat them for the winter and spring have planted to a permanent place. But opinion was divided on the forum, and I all in doubts... "

To decide whether it is necessary to plant the plants in autumn, and how to protect them from frost, you need to know the effect of lowering the temperature for different types of crops:

• Thermophilic plants are sensitive to lower temperatures, even up to -1 ° C. Therefore, in the autumn it is not necessary to plant tomatoes, eggplant, peppers.
• If culture is necessary to land close to the surface, frost may harm them. Therefore, if there is a chance of frost, refuse landings of cucumbers, squash, zucchini, and so on. D.
• Cold-resistant vegetable crops are not afraid of severe frosts. These include parsley, carrots, onions, spinach, beets, fennel. They are planted in the fall, when the likelihood of a thaw small. Spring shoots will appear faster.
• Fruit trees are sensitive to frost. Even at a temperature of -1... -2 ° C kidney and ovary die. If you plan on planting trees, wrapped them qualitatively. It is important that the fall in the trunk sap flow has not started. Less afraid of cold apple, some varieties of cherries and plums.
• Ornamental trees are more hardy to frosts. Therefore, they are often planted in the fall. At the level of the crown temperature is higher, so the trees can withstand even severe frost.
• Many species of ornamental shrubs planted in the fall, too. With proper care open branches not freeze even at a temperature of -8 ° S.No on shoots should be the leaves and buds. They can not withstand frost.

To protect plants from frost in the autumn and spring gardeners, gardeners use a number of techniques. Some approaches are simple and effective. There are sophisticated techniques. Summer People with experience are advised to take the following actions.

Sprinkling

If a small portion, and the estimated freezing slack (not lower than -2 ° C), it is possible to use this method. It is important to understand that watering should be done by sprinkling a finely divided. If you moisten the soil of the conventional hose, the water will turn to ice. This will only aggravate the situation.

If the soil is moistened fine mist, it slowly cools off and evaporation to protect plants from frost. On the hose to wear special sprayer and sprayed with water the ground part of the bush, tree or vegetable crops. Likewise treated soil.

Water, freezing, releases heat. It will be a real salvation for the plants. Watering is carried out at night at a temperature close to 0 ° C. The steam produced in such conditions, a high level of thermal capacity.

dymlenie

This method requires a lot of time and effort, as cottager directly involved in the process from the evening until the morning. If the temperature drops to + 1 ° C, kindle fires. Smoke must travel along the ground surface. He is warmer than the air, so it will rise. While the smoke is at ground level, he does not miss the cold air to the plants.

This method is effective when there is no wind. Otherwise, fire, fire can spread to plants. Because of this, the fire will happen. Therefore, growing some crops, such as grapes, using special flue installation. The fire can not spread to the area.

If there is no special equipment, straw, dry litter, sawdust around the perimeter make small heaps. The center drive in the count, which will hold the material in one place. Top lay wet straw, wet leaves or other slow fueled handy tools. This will ensure sufficient amount of smoke without flame. Morning pile sprinkle a layer of earth. As the burning make new heap to the amount of smoke it was sufficient.

formation of shelters

Gentle cultures do not even planted under the shelter. Seedlings are grown in a closed heated space. Shelters do for perennials that can not survive the winter, hardy vegetables and berries. covering materials applied with the onset of cold. Some of them pull on the frame, the other can be spread on the plants.

Shelters will protect the roots of plants, which in the autumn planting is not enough strengthened. Some gardeners use for that make-shifts, for example, old coats, blankets and so unnecessary. But the right to use a special covering materials for these purposes. Experienced gardeners selected dense insulation. They can be film or fabric.

Top you can sprinkle materials dry leaves and twigs. In shrubs and trees wrapped tops and trunks only with the onset of frost-resistant. After all, the day yet still warm, so wrap can lead to the development of diseases under the covering materials. Therefore it is best covering materials suitable for the period of possible frost, can "breathe". The steam passes through them, but the heat is kept inside.

For creating shelters of straw, dry leaves and grass, compost. The selected material is spread over the surface of the soil after watering evening. This is a very effective way. Combining it with drip irrigation, can protect plants from frost.

Heating

This method is suitable for those summer residents, who grow vegetable crops in greenhouses. If it gets very cold, it need enamel bucket with a lid. You also need to take 2-3 large pieces of coal. The bucket cover hole is made, through which the pipe is withdrawn. Her second end should be outside the greenhouse. The pipe must be of galvanized steel. Position through which it passes through greenhouses material paving mineral wool.

While coal is smoldering in the bucket in the greenhouse will be zero temperature, even in severe frosts. Instead of buckets can be used portable heaters, barbecue. But the top holes and needs to close. Otherwise embers can fall on sprouts, cause a fire.

top-dressing

Less effective method is the application of fertilizers. It is combined with other crop protection methods. Some types of baits have a positive impact on the crops ability to resist frost. To do this, use a product containing phosphorus and potassium. The compositions of the nitrogen, on the contrary, make even the hardiest plants are more vulnerable to frost.

In the period before the possible onset of frost is necessary to lure horticultural culture of phosphorus-potassium fertilizers.

Just a few tips ...

In some cases, the affected plants can be to try to bring back to life. They are sprinkled with cold water, which will reduce the rate of evaporation. Vegetable crops are sprayed with antidepressants, such as drugs, "Novosil", "Appin". Can be diluted matchbox urea 10 l of water. This composition was treated the affected plants.

Not to miss the freezing time to prepare, you need to learn about their normal occurrence in this area. Before the frost set windless, dry weather, and in the evening the air temperature drops sharply. Atmospheric pressure increases, the sky is clear and starry. Nature trails off as if not even heard croaking frogs and singing of nocturnal birds. This suggests the occurrence of frost. It's time to take appropriate action.

Cottagers recommend to choose to protect the future of the crop is not one, but several methods. Moreover, for each specific site and climate characteristics will suit a particular method.
