Features of growing and subtleties of plum care
Care for the plum tree, as well as for other garden plants, consists in regular watering, top dressing, loosening the soil, pruning and shelter. This culture does not tolerate drought, so watering is extremely important for it. Moisten the plant as needed.
Usually, during the growing season, plum is enough with 3 irrigation, and in hot weather it is better to increase their number to 4-5 procedures. After each irrigation or rain, the soil needs to be loosened - otherwise the earth will be taken up with a crust and the rhizome will not receive enough oxygen. Variety Opal also needs fertilizers.
Gardeners are advised to feed the variety according to the following scheme:
- in March - add a mixture of 10 l of water, 30 g of superphosphate, 30 g of potassium salt and 30 g of urea;
- after flowering - any drug based on potassium and phosphorus.
4 years after planting a tree, the soil must be loosened and 10 kg of compost applied per 1 m² of land. Equally important for plums and pruning. After winter, gardeners must remove frozen and damaged stems. Formative pruning should be done in the fall after the growing season or in the spring before it begins. The crown is formed so that the branches grow in tiers.
The winter hardiness of the variety is average, so the trunk circle for the winter must be covered. To do this, it should first be spudded, and then covered with agrofibre. So the root system of the plant will better tolerate frosts.
