In public parks and near hospitals, it’s recommended to plant trees that serve as excellent “sanitizers,” such as spruce, juniper, birch, pine, and oak. These trees help eliminate harmful bacteria and purify the air. For noise barriers, consider using fir, spruce, thuja, linden, hornbeam, as well as climbing plants.
In areas where the air is saturated with exhaust fumes and gasoline vapors, it’s best to cultivate birch, weeping willow, sugar maple, and winter oak.
Seedlings for urban streets are grown in nurseries. Before transportation, the roots should be moistened. Trees are planted in pre-prepared holes with a diameter of at least 4 feet. They are secured with supports—straight wooden stakes about 8 feet tall. The supports are placed on the windward side, 2-3 inches away from the trunk. The seedling is tied to the support in two or three places.
The timing of planting is crucial for the survival of fruit trees and berry bushes. Apple trees and bush berries, being more resilient, can be planted in the fall (about a month before frost) and early spring. Stone fruit varieties, pears, and grapes are primarily planted in spring. Apple and pear trees should be two years old, while stone fruits can be one year old if they have a developed crown. For currants, gooseberries, and grapes, it’s best to choose two-year-old or one-year-old plants (if they are well-developed), while raspberries are planted as one-year-old root cuttings.
In the center of the hole, a stake 5 feet long is driven into the ground. Organic and mineral fertilizers are added to the soil. Damaged and frozen (blackened) roots are trimmed, and seedlings are soaked in water for 8-10 hours. Trees that have dried out should be placed in water for 1-2 days. During planting, the root system is dipped again in a liquid mixture of soil, clay, and manure.
Immediately after planting, water the seedlings with 3-4 buckets of water each, depending on the soil moisture. Then, cover the hole with loose soil, and to retain moisture, add a layer of well-rotted manure or composted peat about 3-4 inches thick. Seedlings are tied to the stakes.
Currants and gooseberries should be planted 1-2 inches deeper than they were in the nursery, while raspberries and gooseberries should be planted at the root collar level. After planting, water the plants with 1.3-2.6 gallons of water for each hole.
Only a properly planted tree will take root, thrive, and bear fruit.
