You need to know why the apple tree drops apples in order to understand what to do
The abundant flowering of the apple tree in spring, the healthy appearance of the tree promised a generous harvest of everyone's favorite fragrant fruits. But the apple blossom falls, covering the ground with a veil, and later the ovaries quietly and modestly began to fall off. Why does the apple tree drop apples what to do, how to help it bear fruit?
Signs of starvation or biological regulation of the crop
An attentive gardener will always distinguish between the state of the apple tree and what it needs. If all agrotechnical measures are carried out on time, then there are several reasons for the dropping of the ovaries, as well as their timing:
- Regulation of fruiting. The tree bears only as much fruit as it has enough food supply.
- Poor pollination during flowering, no ovaries formed.
- Falling as a result of the development of garden pests caterpillars.
- Varietal characteristics in terms of ripening period.
Fruiting regulation means that the apple tree needs constant care during the season. Why do apples fall in June? A healthy tree requires a constant supply of food. Moreover, each stage of development needs its own nutrition. So, in the spring and until July, nitrogen fertilization... They are held regularly every two weeks. It should be remembered that the most active small roots are not located at the trunk, but at the level of the tree crown border.
It is necessary to feed the entire trunk circle. You need to make small grooves and pour in the fertilizer for absorption. You can drill multiple holes with the ice auger for ice fishing and pour nutrient solution into the recesses.
To maintain a good harvest on a healthy tree, it is necessary to organize abundant watering of the garden. But with waterlogging, aeration of the earth will be required. With excess moisture, fruit can be dropped.
Sprinkling apples before the end of the season can mean ripening of the variety. Therefore, when planting an apple tree, one should take into account when the biological ripeness of the fruits comes and harvest them in time.
Garden pests and control
Pests cause great damage to the garden. Among them, insects should be noted, which damage the fruit from the inside, destroying the seed chamber and causing the fruit to fall off. In the August carrion there are often only wormy apples. The reason is the apple moth pest. Measures to combat it are known. But the effectiveness of the treatments carried out depends on the characteristics in the development of the insect.
Lovers of gardeners should know that the butterfly shown in the figure can damage the tree, populating up to 700 fruits per season with its larvae with two years. Each butterfly lays up to 120 eggs. The caterpillar damages 3 fruits during the development period.Over the summer, up to 3 populations develop in the southern regions, one in the north. The biology of butterflies is such that the caterpillar hibernates in the bark of trees, plant debris and in the ground.
In the spring, it pupates, and the emergence of the butterfly coincides with the end of the flowering of the garden. The years are extended, within 39 days after the end of flowering, intense, later depending on weather conditions, but up to 90 days is possible. Therefore, without chemical treatment of the apple tree from the pest in the summer, the garden can lose most of the harvest.
Control measures against the apple moth:
- cleaning and disinfection of trunks, containers and storages;
- spraying with insecticides at the beginning of intensive flight of butterflies of each generation;
- installation of pheromone traps;
- the use of drugs that regulate reproduction;
- cultivation of varieties that are little susceptible to the pest.
Cleaning is necessary not only for the near-trunk circles, but also for the exfoliated bark, since the caterpillars hide in any accessible cracks. Frost of 30 degrees can destroy them in winter for five days. Therefore, warm winters cause a large emergence of the pest in spring. At the same time, the spring treatments of the garden will not significantly reduce the number.
The caterpillar turns into a pupa and ends the development cycle with a butterfly only at the end of the garden's flowering, when ovaries appear, and there is where to lay an egg. It represents a translucent translucent droplet about a millimeter. It is deposited one by one per leaf or set fruit. And all of more than a hundred. Therefore, when butterflies appear, they should be destroyed in the first week, before they have time to start laying.
Insecticides kill the butterflies that have already hatched. But the term of their appearance will be extended. Therefore, two treatments should be carried out at an interval of 10 days. Both chemical and biological preparations are used. The use of specially prepared preparations for a single treatment during mass flight after flowering is effective. The preparations proposed by scientists Insegar (25% d.p., 0.6 kg / ha) and Admiral (10% EC, 0.6 l / ha) will help reduce the number in the first generation to insignificant.
Pheromone traps, vessels with liquid with a fruity smell, attraction to light, all are used by gardeners in the struggle for the harvest. Females drown in these traps, which need moisture and nutrition.
Caterpillars pupate from fallen apples. Therefore, the carrion should be collected and buried deep in the ground so that the caterpillars cannot get out. At the same time, hunting belts are installed, from which caterpillars are regularly selected.
Late varieties of apples are less damaged by pests. Such varieties as Antonovka, Saffron Peptin, Tellisaare are considered resistant.
To get a full harvest of apples from a tree, you need to create conditions for him to pour delicious ruddy apples. To do this, feed, water and protect from pests. see also apple tree disease pictures!
Yeah, fill up the "holes" for fertilizing and then THERE will trample undergrowth ... that's what happened to the pear. No stupid drilling tips now
