Forks occur when there are sharp angles of discharge (less than 40 degrees) in the event that the lateral branch is almost the same thickness as the main branch. The accretion of the branches that make up the fork is fragile, which leads to its breaking during the fruiting period. Do not leave skeletal branches and ramifications with an acute angle of departure. All lateral branches extending from the central conductor at an acute angle must be cut “into a ring” or turned into fruit-bearing branches.
Against pests of raspberries and strawberries before flowering and after harvesting, use karbofos (against aphids), sulfur preparations (against ticks). To control pests of strawberries, use also kilzar, against gnawing pests - lipidocide. Karbofos (75 g per 10 liters of water) is advisable to use against raspberry bud, shoot moth - at the beginning of bud opening, when caterpillars bite into them, as well as against raspberry-strawberry weevil and raspberry beetle (during budding of raspberries and strawberries) and raspberry fly (at the beginning of regrowth of young shoots).
During raspberry flowering, it is easy to find shoots damaged by raspberry fly larvae. Cut off their ends slightly below the point of penetration of the larva and destroy. Treat areas infested with transparent strawberry mites with karbofos immediately after harvest. Before spraying planting strawberries, only heavily populated with mites, mow, and collect the leaves and destroy. Water and feed the strawberries after mowing to help plant next year's harvest. If there are few pests, try to deal with them without mowing the aboveground part, strawberries, since its leaves are already working to create a future crop. After harvesting, carefully cut and burn the fruit-bearing shoots and blackened leaves.
Very often, gardeners complain that their fruit plants are developing very strongly, but they are in no hurry to enter fruiting. There are many reasons for the late entry of fruit trees into fruiting, but one of them is that under very favorable conditions of mineral, especially nitrogen nutrition, flower buds often do not form. In such cases, it is necessary to prevent the outflow of assimilants from the aerial parts to the roots of the tree. The easiest way to achieve this is by bending back some of the branches and securing them in a horizontal or drooping position with rubber bands and wire or twine. Perform this operation at the end of June. Fold back about 25% of the overgrown branches of the tree, that is, those branches that cover the skeletal branches and skeletal branches and on which flower buds form.
The bulk of plants are carbon. It accounts for an average of about 45 percent of the dry weight. A small portion of the carbon enters the plant from the soil. Its bulk is absorbed by leaves from the air in the form of carbon dioxide. From it, the plant assimilates only carbon, while oxygen is released back. Indeed, there is relatively little carbon dioxide in the air. Due to the high demand of plants for carbon and its low content in the air, fertilizing with carbon dioxide is required. For example, in greenhouses it is relatively easy to increase the content of carbon dioxide in the air, gardeners put containers with manure there, etc.
In garden conditions, the content of carbon dioxide in the air can also be slightly increased by introducing easily decomposing organic fertilizers into the soil, which enrich the lower layers of the air with carbon dioxide and improve the carbon nutrition of plants. More dramatically improved carbon nutrition can be achieved indirectly by improving leaf activity. Dark green leaves, rich in chlorophyll, absorb 2-3 times more carbon dioxide than light green leaves, poor in chlorophyll.
