When should garden trees be treated in spring?
With the onset of warm days, spring work begins for gardeners. Indeed, not only trees wake up from the sun's rays, but also pests that have overwintered on them. In order to preserve the plantings and prepare the garden for the fruiting season, a number of activities should be carried out, including cleaning the trees and directly treating them with special preparations.
Preparing trees for spraying
First of all, all trees must be carefully examined and branches that have dried or frozen out cut out. At the same time, crowns can be formed or straightened. You can start working from about mid-March.
Leaves fallen in autumn, which have not rotted over the winter, must be raked and burned along with the cut branches, since they may contain pest larvae.
In early spring, the air temperature is not yet stable - the sun is hot during the day, and frosts are possible at night. To protect the bark of trees from burns, the trunks should be whitewashed slaked lime with the addition of PVA glue.
Before whitewashing, the trunk must be cleaned of dead bark and lichens.
The last preparatory step will be digging in the near-stem circles. It is advisable to do this a couple of days before spraying the trees.
As for when to process garden trees in spring, you can start the first spraying as soon as the air temperature warms up to 5 degrees Celsius.
Stages of spring processing of trees
Garden trees must be processed 4 times during the spring season:
- Before bud break... Spraying of plantations in order to destroy the remaining larvae that have awakened, as well as pathogens of such diseases as scab, cytosporosis, moniliosis, coccomycosis, etc. Preparations: bordeaux mix, iron and copper sulfate, carbamide, Fundazol.
- Before flowering (on a green cone)... It is carried out for the destruction of the moth and for the prevention of scab and spotting. Preparations: a mixture of vitriol and slaked lime, diesel fuel solution, Keltan, Fury, Kinmix.
- During flowering... Reprocessing of trees against clasteosporia, moniliosis and coccomycosis. Spraying to combat ticks and weevils. Preparations: copper sulfate, Bordeaux liquid, anabasine, DDT, karbofos.
- After flowering... Treatment against fungal diseases. Destruction of pests. Preparations: Fury, Skvor, Fundazol, Marshal, Barrier.
The break between each subsequent spraying should be at least two weeks.
