Frost protection
In May, many people already have green shoots of carrots, radishes, beets and herbs. And suddenly they come - night, return frosts.
In order not to ruin the future harvest, first of all, it is worth carefully monitoring the weather forecast.
The plants that are given the most attention are the first in the risk group. For example, if roses were cut a week or two ago, they began massive vegetation. Then young leaves of a week or two ago are susceptible to frost.
If tomatoes, cucumbers, peppers and other heat-loving, actually tropical and subtropical crops, are planted in a greenhouse ahead of time, they will suffer from low temperatures.
To protect plants from late spring and early winter frosts, you should know the methods of protection.
Let’s talk about the most common ones:
- covering
The easiest way is to cover small plants with spunbond.In addition to this, you can fill bottles with hot water in the evening and lay them out on the beds.
If there are still few shoots, each plant can be covered separately. Half-cut plastic bottles, buckets or caps made of paper will do.
Important: the cover is put on so that the plant leaves do not touch the material.
- sprinkling
Irrigation of plants is carried out several hours before the expected frost: as a rule, late at night, since severe frosts occur at dawn. At low temperatures, moisture evaporates and thereby warms the air. As a result, the frost does not reach the ground. The sprinkling method is effective at frosts down to -7°C.
Moisture-charging irrigation with water at a temperature of about 10°C is very effective for trees and shrubs.
You can enhance moisture evaporation using a transparent film, which is laid under the tree crown after watering the tree trunks. During the day, the spring sun warms the ground, shortly before the onset of frost, the film is removed - and warm steam rises up, protecting the plant crown from freezing.
- hilling
To protect young potato sprouts (with 3-5 leaves) from recurrent frosts, you need to hill them with earth using a hoe. The layer height should be 7-10 cm.
- organic mulching
This technique is good for vegetable crops. After evening watering of plants, straw, compost and dry grass are spread on the beds. A layer of organic mulch reduces heat transfer from the soil and increases humidity above its surface.
Warm beds made from organic matter also warm crops well from below. And if you additionally cover them with agrofibre, then in such a greenhouse the plants will not be afraid even of severe frosts.
- top dressing
Help plants better withstand low temperatures.
For example, when night temperatures drop to minus 4-5 degrees, vegetable seedlings fall into stress, and the plants will need two weeks to get out of it.
A safe and effective fertilizer for feeding seedlings is potassium humate "Bioresource" Rich Harvest..
This fertilizer combines the anti-stress properties of humic acids and the nutritional properties of available forms of nitrogen, potassium and sulfur. Potassium humate "Bioresource" feeds plants, gently relieving stress and improving immunity
The fertilizer is liquid, it is easy to dose and apply when watering. 15 ml of humate, this is about one cap, we dilute in 10 liters of water, which we water our plants with.
Do not forget that proper planting planning will protect plants from recurrent frosts.
Stone fruit trees, which most often suffer from night frosts during flowering, should not be planted in lowlands.
In addition, do not rush to "relocate" vegetable seedlings to a permanent place in the ground. Plants should be hardened beforehand: take them outside during the day, and back indoors at night.
And, of course, preference should be given only to those varieties that are suitable for the climate of your region.
