Why does an apple tree drop fruits before they ripen and what to do?
Spring is the time of flowering, which will make it possible to harvest fruits from trees in summer and early autumn. Of course, if the winter was not too harsh, and the gardener who loves his garden took all measures to enjoy the harvest of a rich harvest of apples. But the process of flowering and fruit ripening has its own nuances that can lead to the death of the crop. The fall of unripe apples in June-July has already become common.
The reasons for this phenomenon may be different. Either the gardener does not properly care for and process the tree, or the branches of the tree are weak, and the harvest is large, and in the process of ripening the apples simply fall.
Reasons for dropping
In order to take measures to prevent premature fall of the apple crop, you need to outline a number of the most common reasons why this happens and what to do.
- The apple tree cannot bear the excess fruit on its branches and begins to shed them on its own. In this case, we can say that the process of survival is taking place, and those fruits of the apple tree that remain on the branches will absorb the juices of the tree and delight with ripeness and excellent taste.
- Seed ripening has occurred, but the outside of the apples is green. There is nothing wrong with this, collect the fallen fruits and place them in a dry and dark place, where they will ripen on their own.
- The apple tree is dying due to the invasion of pests that destroy not only the crop, but the tree trunk itself. If a worm is found in the fallen fruit of an apple tree, then it is time to start the fight to save the tree.
- Insufficient watering. A banal reason, but very often it causes a decrease in yield and gradual death. If the tree does not receive enough moisture, the process of self-preservation begins at the expense of fruits, which again leads to premature fall. Please note that even if the region is not dry, but wild heat sets in, you need to help the tree and actively water it. However, uncontrolled water supply can also lead to fruit drop.
- The following reason is common among novice gardeners, and those who believe that after planting a tree, it only needs to be dug in and watered occasionally. The lack of top dressing, the use of the wrong substances will certainly affect the quality of apples.
- The apple tree lacks pollination. This is due to the fact that the culture needs the so-called cross-pollination, and for this you need other fruit trees next to it, so that the process of pollinating each other takes place, without this, the fruits may start to fall or not appear at all.
- The age of the tree can also serve as a reason for the fall of apples. In this case, it is necessary to make correct and timely pruning.
- It is worth mentioning early frosts, but this is rather the gardener's fault. If you live in a region with harsh winters, be sure to purchase only hardy varieties. If an unstable variety is nevertheless acquired, and spring frosts have come, then use boric acid in the amount of 2 g per 10 liters of water to treat the tree trunk. You can also use the common drug "Ovary".These actions must be taken immediately to save the crop and the tree itself in the future.
How to fix the problem?
In order not to get solid carrion instead of bulk fruits, it is recommended to use a few tips from experienced gardeners.
pruning
Pruning branches in a timely manner, because most of the crop depends on it. Remove branches that are dry and aged, as well as those that interfere with the proper growth of the crown. If you miss this stage of care, the sun's rays will not break through the crown, and small undeveloped fruits will simply fall to the ground. Pruning is carried out in the spring, and the remaining wounds are poured with garden pitch.
Watering
Provide water from the beginning of flowering, after it ends, the day before harvest, after harvest, and before the start of preparation for winter. If the region is dry enough in the summer, then you can water more often, and at the same time mulch the soil for faster penetration of moisture to the roots and moistening the lower layers of soil around the tree. In addition to the above general measures, the age of the tree must also be taken into account. A young tree of 1 year of planting will require 3 buckets; biennial planting tree - 5 buckets; trees 3-5 years old - 8 buckets; an adult tree from 6 to 10 years old - 10-12 buckets. Watering should penetrate to a depth of 40 to 60 cm.
Whitewash
A necessary step in caring for a tree is disinfection from pests in the form of whitewashing the trunk. Whitewashing can be done in early spring, which will only strengthen the tree trunk. Also take note that disinfection should not lead to scaring off the right insects and harm the tree itself. The most common substance used for whitewashing is slaked lime with the addition of garden glue.Proportion of the mixture: 300 g per 3 liters of water plus 2-3 tablespoons of glue. You can also add a spoonful of copper sulfate here.
If you are faced with the problem of the lack of the above ingredients, then ready-made mixtures for apple trees can be purchased at garden stores or on the market.
top dressing
Fertilizers should be poured or strewed around the tree, to the depth of the bayonet, in order to prevent parasites from waking up after hibernation. The first feeding is carried out only three years after planting. You can use humus or not 500 g of urea. You can also dilute fertilizers and pour around the trunk, but then at least 4-5 buckets, so that the liquid reaches the roots of the tree. Among the fertilizers most used for top dressing, superphosphate is in demand. 25 g of the substance per bucket of water will be enough.
It would also be nice to spray the apple tree. It can be Bordeaux liquid or the necessary mineral supplements. Bred them strictly in accordance with the instructions. Spraying should be carried out on a cloudy day or in the morning, otherwise the leaves will get burned.
Pest control
For the most effective control of pests and parasites, you should have at least a small understanding of them.
Aphid
A subspecies of small insects that cover the leaf and young shoots in a dense layer, and they can be seen with the naked eye. Dense folded leaves will tell you that aphids have started on the tree. In the presence of such a deformation, the leaves must be urgently cut off and burned. Karbofos is excellent for fighting aphids. With this preparation, the processing of the apple tree should be carried out before the flowering period.
Ticks
As soon as mites are wound up on the tree, the leaves immediately turn brown, become covered with sticky cobwebs and fall off.With a massive attack of the fetus by parasites, you can see small insects of a red hue. To destroy this pest, you will need a common drug "Taurus".
Apple moth and leafworm
These are subspecies of parasitic butterflies, and it is they who become the worst misfortune for an apple orchard. These are incredibly voracious pests that, while still in a caterpillar state, are able to gnaw on the buds and young shoots of leaves on a tree, leaving only a clump of cobwebs. In this case, we use a strong chemical preparation "Tanrek", again on the eve of the flowering period. For prevention, dig up the trunk in a circle, and it is better to collect and burn all the fallen leaves from the apple tree and neighboring trees.
Flower beetle apple
It lays its eggs directly into the flower bud, from which the larva hatches and eats everything from the inside. If this happens, you can forget about flowering. The flower beetle comes to life when the first buds appear on the tree, so treatment should be carried out in early spring. In addition to the strong chemical preparation "Aktar", the use of mechanical traps can be undertaken. Wrapping a tree with adhesive tape with special preparations helps well. This action also needs to be done at the beginning of spring, but before a warm temperature is established, that is, until the pest wakes up.
codling moth
The most common type of parasite, due to which the fall of unripe apple fruits with worm marks can occur. From the codling moth, it is necessary to treat with "Decis", but only after the end of flowering, then repeat the spraying procedure twice more, this will increase the chances of the appearance and preservation of the crop. It is also necessary to remove the old and lagging bark from the tree at the beginning of the season, where the codling moth can take root.It is recommended not to dump the collected bark near the tree, but to burn it immediately. Take note that the codling moth is considered the cause of the fall of unripe fruits, a decrease in yield and, as a result, the death of the tree itself. The codling moth is a parasite that must be dealt with immediately when it is detected not only on the apple tree, but also on other fruit trees on which pollination depends.
Thus, in order to understand why the apple tree sheds fruits before they ripen and what to do, you need to take into account the factors discussed above, precautions and have at least a superficial knowledge of caring for garden trees. Also, in order to avoid crop loss or not pay so much attention to the garden issue, you can use the latest ripening varieties, such as Pepin Saffron, Antonovka, Pobeda, Tellisaare.
