Planting and care
The best time to plant is early spring. It is important to have time to plant a seedling in the period from complete melting of snow to the beginning of bud break.
For Egg Blue is best suited. wet loamy soilwith high calcium and low acidity. Groundwater at the site should not be located above 1.5-2 m.
It is better to plant a tree on well-lit and warm slopes.
The soil for planting is prepared in the fall: they dig well and lime. At the same time, the landing pits, about 60 cm deep and 70–80 cm in diameter, are also being dug out. 400-500 g wood ashand then fill with cooked primer. To do this, the top layer of excavated earth is mixed with two incomplete buckets of compost or rotted manure and add 0.5 kg of superphosphate and 0.1 kg of potassium sulfate.
A peg is placed in the prepared pit and the seedling is carefully placed, gradually dropping and tamping down the soil.
The root neck when planting is left 3-4 cm above ground level. The tree is slightly tied to a peg, and around the roots make a deep hole for watering. After planting, the seedling is watered abundantly. For better survival growth stimulator solution can be used (3 tablets per bucket of water). After watering, the soil around the trunk is thoroughly mulched with dry peat or compost.
Begin to apply fertilizer only a year later after landing. Conduct 2 dressings with nitrogen fertilizers: at the beginning and at the end of June. After that, once every 2 weeks, foliar fertilizers can be used as a growth stimulant.
In the third and subsequent years, before the onset of fruiting, fertilizers are applied three times per season: in May, June and August. May feeding is good to do with a solution of urea (3 tbsp. Per bucket of water), in June you can use the same amount of nitrophoska, and in August - superphosphate and potassium sulphate (3 tbsp. Per pail of water). At least one liter of such fertilizers should be per tree.
In the fifth year, when the tree begins to bear fruit, fertilizing is done 3 times: before flowering, during the ripening of the berries and after their collection. At the same time you should not forget about regular weeding, watering, loosening and mulching. In the summer, a mixture of dry peat and dolomite flour is perfect as mulch.
The first pruning of the tree is carried out immediately after planting. At the same time, no more than 10 main branches are left, from which the crown will be formed, and the rest will be removed.
For this spring, it is necessary to remove all frozen and diseased branches, shorten growths and remove unnecessary shoots. We must not forget about the removal of the root growth to give the tree more strength to grow.
"Egg blue" possesses amazing winter hardiness and does not need shelter from frost. To protect against damage by rodents, the trunk can be wrapped with a thin polymer mesh or wrapped in old nylon pantyhose.

Holey blotch or congestion primarily affects the leaves of the plant. The first signs of this disease are the appearance of small red spots on the leaves. Over time, in their place there are holes.
The disease is caused by a fungus that develops well in wet and cool weather. Affected by this not only leaves, but also young green shoots. The spores of the fungus are spread very quickly by the wind, and they can infect all bone crops that grow nearby.
Various fungicides are used as measures to combat this disease. It is important not to use the same tool all the time, but to alternate between different types of drugs.
Moth can also seriously damage the plum crop. These insects feed on both ovaries and ripe berries. Caterpillar caterpillars and adults also cause great harm.
Measures to combat this pest consist in scraping the old bark from the branches and trunk, as well as in the use of special trapping belts. Every 2 weeks they are checked and destroyed by pests. If the moths are too much, then apply spraying wood with special preparations.
Not less damage to the plum brings aphid. It appears in the young root overgrown trees and spreads throughout the plant. Aphids feed on the sap of young leaves and shoots and can greatly weaken and even destroy the tree.
To combat aphids, first cut off all root growth, scrape off the old diseased bark and lime the trunk and main branches. Well helps processing wood "Inta-Vir" or a solution of soap.
