How to save the seedlings of tomatoes in the greenhouse frost.

In late spring, early summer, summer residents should pay attention to weather conditions and weather forecasters. If soon at night the temperature falls below - 7 degrees, you should immediately begin to rescue seedlings. If you leave it to chance, the young plants, which have not yet had time to grow strong, could be seriously affected.

In no case do not leave the tomatoes, hoping that everything will be, because such actions will allow the seedlings to die, and all carried on the cultivation of work will be in vain. To tomato seedlings grew strong, need to do a simple job, which will be discussed further.

What can cause recurrent frosts

Survive the low temperature or the seedlings or seeds can not. Therefore, the plants need to cover before the fruits begin to ripen. Return frost can cause considerable damage to young seedlings.

Before the occurrence of frosts seedlings need to provide additional protection. Even slight frosts in the future may harm the crop. In plants, there is a cell sap, which freezes, leading to rupture of the membrane.

What plants are especially in need of additional protection

More susceptible to recurrent frosts, crops such as:

cucumbers;

Pepper;

melons;

eggplant;

berries;

Tomatoes.

Even if the temperature drops to just - 1, then these plants will stop in development, and in the future will bring poor harvest or will not give it at all. The slowdown may last from 10 to 15 days, sometimes longer. Also worth noting is that these plants are even grown up in a state of ill-protected against frost, so at the time of the pick in an open ground, you need to be as careful.

How to protect from frost Culture

To protect plants growing in a greenhouse or a greenhouse, the following methods must be used:

Dark plastic bottles are an excellent means of warming. Bottles filled with water, placed throughout the greenhouse area. To enhance the effect, it is recommended slightly prikopat capacity. Throughout the day, they are heated, and at nightfall give off their heat plants.

In use as a warming means cobbles. But to accumulate heat and to share it with the land and seedlings, they will be much slower.

Seedlings, which is in the greenhouse, should cover spunbond or other material pre-established on the arc beds. The edges of the material have to press firmly to the ground, so that cold air does not penetrate into a mini greenhouse. But it is worth noting that this method is only used if the seedlings did not have time to get stronger, and in the case of cucumbers - are not recorded on the trellis.

To the greenhouse, it was warm, it is necessary to use a polyethylene that is stretched inside her. By means of clamps, the material must be secured to the structure supports. A snug fit to the walls of the greenhouse are required. Between two materials - greenhouse and polyethylene, an air cushion, which will take the cold air, not allowing the plants to freeze. You can use the film on the outside, but this method will need more films.

Many gardeners use hot water tanks or containers with glowing coals.

Maintain a certain temperature of the air is possible by means of electric heaters. Along the perimeter of the greenhouse is necessary to place several heaters so that the hot air does not touch the plants themselves. It is best to use a heater with a timer, that they turn on their own, as the temperature decreases, and turns off when the air warms up to a certain point.
