Do I need to mow or prune the strawberry leaves after harvest? V. SizovaExperts believe that mowing is advisable only if old bushes (at least 4-5 years old) are infected with transparent strawberry mites. In this case, the leaves should be cut immediately after harvest. You need to cut them low, near the ground, since the bulk of the ticks is concentrated in the lower part of the stems. A delay in cutting leaves, even for several days, leads to a decrease in winter hardiness and yield of strawberries in the future. After serious pruning, plants are in dire need of good care - feeding, loosening the soil, watering, etc. The degree of colonization of strawberry plants by mites can be judged by wrinkled young leaves, which have a yellowish oily tint, and bushes that have become dwarf. This pest enters the site along with the infected seedlings.Therefore, obtain healthy planting material from nurseries or from healthy mother bushes.

Some publications provide guidance on leaf mowing when leaf spot is present. However, “blue” spraying of strawberry plantings with 3% Bordeaux liquid before bud break is quite effective here.

If after harvesting the plants are healthy, there is no obvious damage, then trimming the leaves is not necessary. The retained leaves encourage the formation of new buds for next year's harvest. In this case, you only need to remove the old dead leaves, loosen the soil, feed and water the plants, especially if the weather is dry.

To reduce cross-pollination of different varieties of tomatoes, regularly tap and shake their flower brushes. For greater assurance, do this several times a day.

By the way, this technique will simultaneously increase the number of formed ovaries, which in itself is very valuable.

Hazel, or as it is popularly called, hazel, grows in the Leningrad region. Its large-fruited forms can be found in the south of the region. Hazel grows in the form of a bush with a round, spherical, pyramidal, weeping shape. It is a wind-pollinated plant with dioecious flowers. One plant has both male flowers in the form of earrings 3-4 centimeters long, and female flowers in the form of buds, at the end of which stigmas stick out. Hazel blossoms in late April. Hazel is propagated by layering, dividing the bush, nuts or offspring. In spring, nuts are sown into the soil to a depth of 5-7 centimeters. Seedlings begin to bear fruit in the 5-8th year. With vegetative propagation - for 3-4 years. Hazel plants are winter-hardy, resistant to diseases and pests. Its nuts are very tasty, nutritious and contain many valuable components.

Onion fly is a dangerous pest of onions. In May - June, she lays eggs in the soil near the bulbs or on dry scales. A week later, worm-like larvae develop from the eggs, which take root in the bottom of the bulb and feed on fleshy scales. Damaged plants begin to turn yellow and dry out, and the bulb rots.

Collect and destroy damaged plants to combat onion flies. Dig up the soil in autumn, as the fly pupae winter in the soil. Change where you plant your onions every year.

Use a plant-based repellent in summer. Do not use chemistry.

In the harsh conditions of the North - West, large-fruited varieties of fruit crops are grown in a creeping form. Trees are planted obliquely, branches are pinned to the ground and special pruning is carried out. There are several types of stanches. They are used in the northernmost regions of the Leningrad Region. In the central and southern regions of the region, there is no need to use the stanza form for planting apple and pear trees, since these crops grow well and withstand winter frosts. The problem may arise due to a lack of heat during the growing season, which affects the ripeness of the fruit. But such conditions are rare.
