Why do unripe apples fall and what to do about it?

It often happens that an outwardly healthy tree suddenly suddenly begins to shed its fruits in June, or even flowers and ovaries fall from it altogether. There are several reasons why a plant may begin to behave this way.

natural causes

It just so happened that only 10% of the total number of flowers will later turn into full-fledged apples. All the rest are needed only as insurance in case of frost, pest invasion, mechanical stress and everything else. The resources of the tree are not enough to feed the remaining ovaries, so in June and even July, falling apples is quite normal. Do not sound the alarm. In a similar way, the apple tree regulates the amount of harvest that its nutrients will be enough for.

It also happens that the ovaries fall off later - in August and even September. As a rule, at least 10 fruits remain on the tree, even if the apple tree is already relatively old. If the ovaries remain ominously few, then it is worth looking for the cause in something else. Another reason for premature fruit drop may be a feature of the variety. Many more recently developed hybrids retain fruit for a long time after ripening, however, earlier designs are no different. As soon as the apple ripens, it immediately falls to the ground.

It also happens that apples fall without ripening, and in the future they just need to be allowed to rest. If this does not happen as an exception, then it can also be attributed to the characteristics of the variety.

In this case, it is easy to determine the degree of maturation. It is necessary to examine fallen fruits for damage by pests, as well as for the degree of maturity. The apple should be full and the pits brown. Conduct a similar test not only for fallen fruit, but also for those that are still on the apple tree. You will understand a lot.

Keep in mind: nature intended that apples ripen first on the lower branches, then in the middle of the crown, and then at the very top. So if apples began to fall from the lower branches, this is most likely a signal that the harvest can already be safely harvested. One of the reasons for the premature fall of young apples may be insufficient or excessive amount of moisture that falls on the share of the tree. If annual plants, on the contrary, strive for increased fruiting in the event of a lack of water, trying to produce seeds, then perennial fruit trees are a completely different case. If there is not enough water, then the apple tree may not produce a crop at all, and the apples will fall without ripening. In priority are green leaves, not fruits.

Therefore, if the tree does not receive enough water, then first the small apples turn yellow, rot on the tree and crumble, and only then the leaves. Therefore, it is important to follow the correct irrigation scheme. If, on the contrary, watering turns out to be too superficial and frequent, this is fraught with freezing of the roots. The fact is that water must penetrate deep into the soil in order to envelop the entire root system, and not just the upper branches.In the case of light watering, only the upper part of the roots receives enough water. Therefore, it develops better and more intensively. In winter, when the ground freezes, the roots freeze too. As a result, the apple tree has to feed on poorly developed deep roots, which also does not stimulate further fruiting.

In rare cases, excessive watering can cause the roots to rot. As a result, the entire nutrition cycle of the tree will be disrupted. Then, first of all, the fruits from the upper branches will fall, and then the tree itself will begin to wither. It will be necessary to take a set of measures to level the negative consequences of this. Another reason is the lack of minerals in the soil. This is especially noticeable until July, since during this period intensive flowering and the appearance of ovaries occur, so the plant needs as many various minerals as possible. It is imperative to carry out preventive fertilizing, as well as from time to time to check the amount of certain substances in the soil using simple tests or equipment.

The climate has a great influence on the ability of a tree not to drop fruits prematurely. Recently, late frosts have been increasingly observed, as a result of which the tree is not able to recover on its own, so it makes the simplest decision - get rid of the "offspring". To avoid this, you need to treat the apple tree with protective equipment as soon as the temperature turned out to be close to critical. Lack of pollination is also a common reason for apples to fall before they are ripe. If there are no other apple trees nearby, cross-pollination does not occur, then the process of crop formation itself will not proceed smoothly.

Factors affecting the shedding of unripe apples

Not only natural causes can have a significant impact on the ability of an apple tree to bear fruit. Important aspects are proper care, timely fertilization, suitable conditions for plant growth, as well as their protection from all kinds of pests and viruses. Much depends on the time of ripening apples. For example, it is natural for late varieties to shed a certain amount of ovaries and fruits in the middle of summer. Another thing is if there are an alarmingly many discarded flowers and ovaries. Then we are talking about the influence of some unfavorable factor.

If the fruits are almost ripe, but have not reached the desired condition, and the apple tree has already dropped them, it may be that the plant lacks nutrients in order to grow all the available fruits. A clear signal of this state of affairs can be the presence on one tree of both large, almost ripened fruits, and very small still green ovaries. In this case, the apple tree discards almost ripe fruits and redistributes resources to nourish those that have not yet ripened.

Anyway proper care is very important. It consists not only in observing agricultural practices, but also in timely fertilizing the tree, spraying it from pathogenic insects. At the same time, pollinating insects should not be allowed to fly around the tree either, otherwise there is a high risk of not waiting for the harvest at all due to insufficient pollination. Another factor that does not depend on the efforts of the gardener is the age of the tree. In an old apple tree, all processes are much slower than in a young tree, so it cannot physically provide all the fruits with the necessary resources.However, even this problem can be solved if it is detected in time and correctly approached the problem, armed with the necessary information and preparing the necessary equipment and preparations.

Wrong care

Failure to follow the rules of care is one of the main reasons why apples fall from a tree. Excessive or insufficient watering, wrong choice of location, insufficient lighting, poor neighborhood, lack of pruning and crown renewal, etc. can cause a number of problems with tree productivity.

First of all, it is worth mentioning the neighborhood. For many traditional varieties of apple trees, it is vital that apple trees of some other species grow nearby. Only as a result of cross-breeding can full-fledged ovaries appear. Otherwise, there will simply be no harvest.

Be sure to clarify whether the variety you have chosen is just that. If he needs to cross-breed on an ongoing basis, it makes sense to plant one or two more varieties nearby.

Also one of the most important aspects is tree pruning. It is done not only for aesthetic purposes, but also to remove dead branches, for the emergence of new shoots, to ensure sufficient ventilation inside the crown. Branches should also be thinned out to provide adequate access to sunlight. This also affects whether the tree can give a full harvest.

Before planting an apple tree, it is necessary to properly prepare the place. Do not plant in areas with shallow groundwater. Otherwise, the roots will rot, as an excessive amount of moisture will contribute to waterlogging of the soil.If there is no other place, then you will have to constantly drain the soil to ensure a normal flow of air to the roots. If the tree can eat normally, it will stop dropping fruit.

As you can see, improper care is quite easy to change by slightly changing the approach to caring for the plant. This is within the power of not only experienced summer residents, but also novice gardeners. It is only important to learn the basics, and then follow the recommendations.

Diseases and pests

Among other things, the apple tree can suffer from the invasion of parasites and pests. The most common among those whose vital activity can contribute to the dropping of apples and ovaries is the codling moth. Everyone knows that apples are often wormy, but only a few are able to associate such a symptom with fruit drop. So, caterpillars hibernate in the bark of trees, feeding on fruits in spring and summer, and then turning into butterflies. According to statistics, over the summer, the codling moth can grind up to 650 fruits. At one time, the butterfly is able to lay 115 eggs, while each of the hatched caterpillars is able to spoil an average of three fruits.

Due to the fact that the biological life cycle of the codling moth is equal to the period of flowering and fruiting of the apple tree, a large amount of the crop can be lost over the summer. Therefore, it is necessary to resort to chemical treatments in a timely manner. It is also necessary to process the trunk to prevent the settlement of the codling moth, as well as to set up pheromone traps. The causes of falling apples can also be fungal diseases - scab and moniliosis. To calculate them, you need to pay attention to the general appearance of the plant. With scab, brown spots appear on the leaves, the fruits are also covered with brown growths.With moniliosis, the fruits begin to rot right on the tree, after which they fall off.

The fight against such diseases is carried out with the help of chemicals. They need to be selected depending on the infection.

  • Against scab, plants are treated with a solution of copper sulfate. It is necessary to spray the entire apple tree, starting from the top of the crown, ending with the trunk. The solution will require two or three percent.
  • Plants with monoliosis are treated with fungicides. Abiga-Peak, Planzir, Horus are perfect for this.

The main thing is not to delay the treatment, otherwise you can lose the lion's share of the crop.

Troubleshooting

As for the quality of the soil, sometimes the matter is in its excess acidity. In order to alkalize the soil, use tree bark. It must be applied under the apple tree, mixed with the soil. You can feed the plant using potash fertilizers, since a lack of potassium is responsible for fruit drop. It is also useful to do such top dressing for preventive purposes, applying fertilizer every spring.

Revision of care can also positively affect the quality and quantity of the crop. As mentioned above, regular and plentiful watering is important for apple trees. In the summer, especially in extreme heat, you need to water the tree at least five times a week, while making sure that the water penetrates deep to the roots. Tree pruning is carried out twice a year: in early spring and late autumn after the entire crop is harvested. Do not neglect the pruning procedure, as this can also affect the ability of the plant to bear fruit. Young branches can better bear the weight of the fruit, so they do not drop them.

Check the tree from time to time for infection with viruses or codling moth.Carry out preventive treatments to prevent the occurrence of any disease. Remember that prevention is much better than cure. In this way, you will minimize the risk of falling fruits, and at the same time protect apples from introducing worms into them.

Also plant another apple tree of a different variety somewhere nearby to ensure cross-pollination. Without it, your harvest will not be as tasty. In addition, due to the lack of genetic material, the apple tree will most likely begin to shed ovaries and unripe fruits. Caring for apple trees is not laborious, so one more apple tree will not give you a hassle.

Carefully monitor the condition of the plant, but do not rush to raise the alarm. Perhaps it is due to natural causes.
