Today, almost every household plot can be found planting cherries. When growing a fruit tree, gardeners are faced with the problem of the formation of numerous shoots, which causes inconvenience for gardening and takes away the strength and nutrients from the fruiting plant. To solve the problem, it is enough to know about the peculiarities of their formation and how you can get rid of the cherry overgrowth.
Description of the undergrowth
Shoot is a young shoot that forms on the adventitious or lateral roots of the cherry. The problem of growing territories with overgrown processes is not only aesthetic in nature, but brings practical harm. If you do not fight the emergence of overgrowth, then it is able to displace not only the parent tree, but also other types of fruit crops.
The peculiarity of the growth of young shoots is that the young shoot provides itself with nutrition at the expense of the parent tree, thereby making it weaker. A significant amount of overgrowth negatively affects the growth, fruiting of cherries and, in the absence of timely measures, can cause the death of the tree.
Most cherry varieties tend to form young shoots. On a grafted tree, such shoots have no value, since it is impossible to grow a full-fledged tree from them, and a wild game will grow from them.
It is not worth expecting the growth of a full-fledged fruiting plant from Robinovka, Molodezhnaya and Rastorguevskaya cherries.
Own-rooted varieties are able to form cherry shoots, with which you can propagate plantings. These include varieties:
There are a limited number of fruit tree species that do not have the ability to form new shoots. A significant part of them are grafted on a seed stock of Vladimir cherry or Shubinka. Among the varieties that do not give rise to cherry growth are bush plants:
- Chocolate girl;
In connection with such features, when buying a tree, you should check with the sellers about the features of a particular variety and purchase seedlings only in specialized nurseries.
Causes of shoots
Overgrowth formation is often the first signal of cherry health problems. With the large formation of new shoots, the tree strives to continue its life span as quickly as possible. There can be many reasons for this situation, but they are all associated with a violation of the rules for planting or caring for a plant.
The main ones include:
- the tree is not deep enough, and the root system is excessively bare, in this case it is enough to add soil;
- in the spring or during grafting, too many branches were cut off, in this case the balance between the root and aerial parts is disturbed, and the roots let excess nutrition to form young branches;
- the trunk or branches of the cherry have undergone mechanical damage, as a result of which wounds or cracks have formed;
- physiological incompatibility between rootstock and scion;
- damage to wood caused by exposure to cold or heat.
By eliminating the main causes of the appearance of overgrowth, you can reduce the ability of the tree to form them. In this case, young shoots must be removed correctly, otherwise the situation can be aggravated, and they will begin to form at an even greater speed.
Low temperatures can cause root damage. In extreme heat, the soil cracks, and the roots can also suffer. Growth often appears on the affected area. To exclude such a situation, a tree shelter is formed in the winter. In hot weather, the roots of cherries are protected by hay, which allows moisture to remain in the ground for a longer period.
In some cases, young shoots do not grow on the ground, but are formed below the graft area. An alien branch may even begin to bear fruit, but its characteristics and appearance will differ from the parent. Such shoots are removed, and with their significant ingrowth, they are pruned in the spring and re-grafted with another variety.
Positive traits of overgrowth
After infection of cherries with coccomycosis, gardeners are often forced to buy new seedlings for replacement. New varietal plants are not always bought in specialized nurseries, therefore, purchasing from random unverified sellers leads to plantings of low-hardy, low-yielding, self-fertile cherry species with low quality characteristics of fruits.
Unique varieties of cherries can be quite expensive, so not everyone can afford to acquire a unique look. The formation of shoots in varietal cherry species allows the plant to propagate, while not requiring financial costs from the gardener. At the same time, there are no restrictions on the territory for increasing plantings, and planting and caring for a young seedling from such specimens will be standard.
Ways to fight
Today there are two main methods of dealing with cherry overgrowth. The first involves mechanical action and is often used by Russian gardeners. The second is associated with the use of chemicals from the group of herbicides. Both options for removing overgrowth have both supporters and opponents.
Many gardeners, trying to get rid of cherry sprouts, make the mistake of digging up young shoots. With such actions, the replacement program is launched, which is characteristic of all coppice trees. At the site of the excavated shoot, 3 or 4 new ones grow, as a result, after a couple of years, the shoots literally fill the territory.
As a result, despite numerous efforts and spent time, gardeners get a garden plot overgrown with cherry bushes, while numerous new cherry shoots negatively affect the growth and fruiting of not only the parent tree, but also other fruit crops.
If it is necessary to remove overgrowth, it is required to cut out part of the shoot with a pruner, cutting off its main part and leaving an area of 20 cm from ground level. At the same time, the formation of roots and new processes will stop. At the same time, the cherry will redirect the forces in full to fruiting, and the tree will stop multiplying by shoots.
You can get rid of shoots with the help of drugs from the group of herbicides, but a significant part of gardeners advise to abandon this option. At first glance, it is possible to remove the growth with the help of chemistry simply and quickly, it is enough to spray, and the young shoots of the cherry tree die. In this case, one should take into account the fact that the shoots and the parent tree are inextricably linked, therefore, through common juices, the risk of ingestion and infection is possible.
To combat cherry growth, general herbicides are used. Such preparations are capable of destroying all plants, therefore their use requires special preparation and strict adherence to the rules of use.
The following types of herbicides are often used:
- "Tornado" is a highly concentrated agent capable of destroying lignified growth;
- "Roundup" - intended for the destruction of grassy weeds, capable of eliminating not lignified shoots;
- Hurricane is a powerful herbicide that is more effective when used in dry weather.
You can remove overgrowth with drugs on stumps. The product is diluted according to the instructions, for most of them the recommended dilution ratio with water is 1 to 3. Before use, several small holes are drilled in the stump with your own hands, into which the mixture is poured. Polyethylene is placed on top to avoid the problem of splashing the drug during rain. In this state, the stump is left, depending on the size, for 2 or 3 weeks. After that, the sequence of herbicide treatment is repeated. As a result of such actions, the stump will decompose more quickly, so it will be easier to uproot it.
Some gardeners, when buying an old plot with perennial plantings, resort to the method of completely digging up the territory to form new plantings in the future. This method is cardinal, but quite expensive and often impossible due to the peculiarities of the organization of personal plots and nearby structures.
Measures to prevent overgrowth should be considered before planting cherries, which will further facilitate gardening work. The fruit tree forms shoots only on the processes of the bark system, located no deeper than 40 cm. In this regard, it is enough to dig a growth restrictor into the ground so that in the future the problem of overgrowth formation does not bother. The following are often used as a barrier:
- plastic sheets;
- a mixture of mown grass, branches, straw;
To form a barrier, the material is dug in in a circle to a depth of 50 cm at a distance of 1-1.5 m from the cherry. The formation of shoots will be observed for some time only at the trunk, they must be cut off with a pruner. Even if individual shoots manage to germinate through the barrier, the scale of the disaster as a result will be much smaller. To reduce the formation of cherry overgrowth, mulch from plant materials, which is placed around the tree in a layer of 20 cm, will help. The overgrowth can also germinate from the seeds of fallen cherry fruits. To prevent such a possibility, you should harvest in a timely manner, and in case of falling berries, they should be picked in a timely manner.
