In landscape design

Pine is so unpretentious for top dressing because it has a developed and strong root system. In winter, at a time of heavy snowfall, branches can break, causing the cone shape to break. Therefore, it is useful to prepare in the fall - to tie the crown in a circle, pressing it to the trunk, thereby protecting the integrity of the tree.

- scoop (damages the needles, help from the butterfly - “Decis”, “Karate”, “Aktara”, “Enzhio”, for use, you need to look at the instructions of the preparations);
- shields (feed on the needles that die off due to them, use Calypso or Confidor Maxi against these pests);
- bark beetles (noticed holes - it means the tree is affected, preventive treatment is used in early spring with compounds based on Bifentrin);
- ticks (they use acaricides - drugs that process the tree 2-3 times a week later);
