Good afternoon, my reader. The flowering phase of most plants traditionally coincides with a temporary drop in nighttime temperatures. Such frosts are called returnable, and currants always need protection from them.

The degree of frost resistance of currants
The currant belongs to the gooseberry family, which often suffer from spring frosts, as flowering occurs at this time. When the temperature drops to -2 ° C, the buds and ovaries almost always die. It has long been noted that when the bird cherry blossoms, frost should be expected. In some regions, they happen at the end of May - June.
Currant protection in spring
There are several proven ways to protect crops from a cold snap.
Top dressing root and foliar
The day before the expected onset of frost is sprayed with a solution of phosphorus-potassium fertilizer. If a decrease to 0 ° C is expected, then 10 hours before this, the bush is watered with the same fertilizer. This helps to reduce stress and will be a timely feeding. Preparation:
- pour 50 g of superphosphate with a liter of warm water and insist for 3 hours;
- filter and dilute in 10 liters of water;
- add 20 g of potassium salt, mix.
Root dressing is combined with regular watering so that the roots do not burn.
Evening watering
Watering the currants at the root overnight will reduce the impact of the coming frost. When the temperature drops, water evaporates, thereby it heats up the air, and cold masses will not be able to sink to the ground.
Sprinkling
For the effectiveness of the method, calm weather and freezing temperatures are required. Experienced gardeners irrigate plants towards the middle of the night, a couple of hours before frost.
Sprinkling is carried out with a spray hose or using a spray system. Reception gives the same result as watering at the root.
Smoke
Smoke is usually used to protect trees, while the temperature rises by 2-3 ° C, but this is also effective for bushes. Windy weather will significantly reduce the effect and smoke will spread to adjacent areas.
The fire is made at the moment when the thermometer mark shows 0 ° C. To create continuous smoke, dry material is thrown into the fire:
- leaves;
- straw;
- firewood;
- dry branches;
- withered grass.
A bonfire is made with a diameter of about 1.5 m and a height of at least 0.5 m. But not one, but several of them are required. Campfires are placed on the leeward side with the calculation of one per hundred square meters. If there is only dry material for the fire, then it is moistened with water. Bonfires are checked several times during the night and kept smoldering.
Covering material
Covering protection is the simplest and most popular way to preserve the ovary on the bushes. A transparent canvas is used, but it cannot be touched by the foliage. The best solution would be to install an impromptu greenhouse greenhouse. There is an option of installing 3-4 arcs over the currants, which are covered with a film. Low young bushes are covered with cut transparent bottles.
