Spirea is an original, hardy and fast-growing ornamental plant that fits perfectly into the different styles of a perennial site. The article is devoted to autumn care for shrubs for those who want to form a beautiful, abundantly flowering bush.

The effect of pruning on the appearance and development of spirea

Spirea is the type of shrubbery that gratefully responds to pruning, even serious. Such procedures stimulate both active plant growth and powerful flowering in all varieties, including spring-flowering and summer-flowering varieties.

The lack of regular pruning, on the contrary, will cause the shrub to look unkempt and turn into thickets with dry branches and weak, unattractive flowering - the bush simply will not have the strength to form new buds. Moreover, if in the middle of summer (July) cut off faded shoots, the bush can bloom again in September! The main thing is not to forget to remove the wilted processes again in the fall.

Thus, the main advantages of pruning are: a noticeable increase in the splendor of the bush, more abundant or even repeated flowering, giving the bush absolutely any shape, including geometric shapes, characteristic of a hedge. In addition, the treated shrub will let in more air and light in time. The procedure will minimize the risk of attack by pests or the occurrence of diseases due to the debate of leaves deep in the crown. Spiraea is almost impossible to cut off incorrectly, so do not be afraid to harm her with this procedure.

Incentive Spirea Trimming Technology in Autumn

Young bushes need only minimal procedures for crown formation. Autumn pruning should be carried out on a fairly mature plantwhose age is about 3-4 years. This procedure is carried out half a month before the onset of the first frosts - this time is enough for the slices to heal, and the plant to restore its former strength for a successful wintering.

It is necessary to remove old and diseased branches with the help of a secateurs - be guided by the level of the root neck, since they will no longer bring any benefit to the plant. On each stalk, leave at least 5 buds. After such a procedure, the spirea will quickly recover, and in the spring young side shoots will increase. By trimming the shrub in this way, you can not only get rid of excess processes, but also thin out the crown.

Before you begin pruning in early autumn, you need to make sure that this is appropriate. The fact is that there are many varieties of spirea: for example, if you have Vangutta spirea or gray spirea planted on your site, then you need to cut the bush immediately after flowering at the turn of spring and summer. Summer varieties, such as Japanese spirea, are best processed in the fall. In addition, stimulating pruning every year is not recommended, as this will adversely affect the quality and abundance of inflorescences in the future. Weak and diseased shoots can and should be removed at any time of the year.

How is anti-aging autumn pruning of spirea carried out

Spirea lifespan greatly affects the processing of branches: shrubs that are more than 7 years old must be subjected to fairly hard basal pruning. If the bush is not updated on time, then the old long shoots will begin to push it to the ground - this will adversely affect the decorative properties of the plant. To “rejuvenate” the bush, absolutely all shoots are cut to the soil level (leave about 30 cm). You can not worry about the bush: with the onset of spring, spirea easily grows a lot of young shoots on the site of old stems. Try not to leave "stumps" on which the lateral processes can grow - this will greatly worsen the decorative shape of the bush.

The best time for deep cutting is September or October. With correctly performed anti-aging treatment, the shrub will gain a second life: it will form a new crown without any signs of aging.

Important! If you pursue the goal of not only rejuvenating the bush, but also reaching the peak of its decorative properties, you should ruthlessly get rid of weak branches at all stages of the plant's life cycle; First, after deep trimming, select the six strongest stems and work with them as with a frame base. The process may take several years.

If even deep pruning did not help, and it is difficult for the bush to acquire young shoots, consider replacing or dividing the spiraea into several parts. It must be remembered that the average lifespan of the spirea bushes is 20 years.

Pruning spirea in the fall after transplanting

Spirea tolerate autumn transplants very well. It is possible to move the plant to a new place as soon as the first signs of a change in the color of the leaves appear on it. On a cloudy day, transplant the bush, and then carry out the necessary pruning, something like sanitization. Most likely, many old, weak and sick branches have accumulated on the transplanted bush, which, drying out, will have a hospitable welcome to parasites and diseases. Skeletal shoots need to be disposed of as soon as possible - they are cut to a pronounced kidney. After this treatment, you can support spirea with fertilizers - so the plant will be better prepared for the winter season.

Scheme and rules for autumn pruning of a spirea hedge

Any kind of spirea can be used as a hedge, but such a green design will require even more attention than ordinary bushes. The fact is that Spirea grows unusually fast therefore, once a hedge is formed without regular pruning, it will rapidly lose its sharpness and look very messy.

Autumn pruning of a hedge is much preferable to spring: so you can gain some time for more important matters at the beginning of the summer season. The ideal time for this procedure is the turn of September and October; green wall pruning is carried out annually - so the fence will have the best density indicators.

It is customary to start processing the young hedge in the second year of the life cycle - during this period the branches are cut by one third of the total increase in length for the whole year. In older plants, branches can be cut to half the length of the total annual growth. If your hedge has been planted for a long time, then it is better to limit to cutting only at the top, since old hedges are characterized by bare lower branches.

After the haircut, the hedge, like any bush, will respond with gratitude to fertilizing, watering and mulch.

Winter Spirea Shelter After Pruning

Even fairly frost-resistant species of spirea need additional warming during the winter season, especially in areas characterized by little snow or severe winters. The better the shelter is built, the greater the likelihood of a successful wintering and abundant flowering for next year.

You can eliminate the risk of freezing of the upper shoots by bending the spirea low to the ground and falling asleep with an impressive layer of leaves (15 cm), branches or vegetable tops. Freshly planted plants must be sheltered in any case: they are still too weak to cope with frosts alone.

Despite the fact that some varieties are able to withstand lowering temperatures to -50 ° C, you should not risk it - winter in Central Russia is not predictable.
