Why in the fall to whitewash garden trees

What is the meaning of whitewashing garden trees?


Whitewashing trees in the garden is an agrotechnical device that primarily protects plants from adverse natural factors, such as sunburn, sun-frost damage to the bark caused by changes in day and night temperatures in late winter and early spring. And any damage to the bark of shtambov or branches - this is the "gate" for the penetration of diseases and pests. With minor injuries, the outer layers of the bark suffer, with heavier injuries, the crust dies to the full depth, baring wood, and then "wounds" attack fungal diseases. The health of the tree is causing significant damage. To whiten the trees you need to preserve the bark, and therefore, for the healthy development of fruit plants. It is easier to prevent the occurrence of wounds than to treat them.


What fruit trees require mandatory whitewash?


In central Russia, many gardeners began to grow tasty and valuable fruit varieties that are not winter-hardy enough for their regions.Therefore, the risk group includes non-zoned varieties intended for cultivation in warmer and southern regions. The most frequent and dangerous type of winter damage to trunk and base of the branches are sunburn. Apple trees (Melba, Spartan, Welsey, Lobo, etc.), cherries, cherries, and plums suffer primarily. Pears are less vulnerable and sunburns are less common. Apricots, so popular with gardeners, and even peaches, are also greatly affected by burns.


Young planting with thin trunks, especially long booms, necessarily require whitewashing and protection.


What can replace whitewash?


Garden whitewash can be prepared by yourself or buy ready-made in the store. But it is often washed away by precipitation. You can tie round with any light material (lutrasil, spunbond, garden universal bandage). When planting young saplings on the south side, it is possible to install stakes, planks in order to shade the bark. You can tie the shtaby for the winter with fir spruce, reed, roofing felt, glassine roofing. This harness will not only replace whitewash and protect the trees from winter burns, but also from mice and hares.


When should trees be whitened?


Trees are usually whitened in late autumn or at the end of winter (end of February-March) at air temperatures above 0 ° C. At the end of winter, before whitewashing, snow is thrown from the tree trunks, and after whitewashing, the snow is returned to its original place, since snow cover reliably protects the roots from frost. To whitewash garden trees in April-May is not worth it. This is ineffective.
