The summer or. Butterfly bush, botanically Buddleja davidii, is extremely popular in this country because it produces beautiful panicle flowers in summer and, as the name suggests, is a magnet for butterflies. However, to ensure that this is the case from the beginning and remains so in later years, it needs regular pruning. This is done in late winter, as there is a ban on cutting from March to September due to the bird breeding season. Here you can learn how to properly prune the butterfly bush.<\/p>\n
Before you pick up the scissors and get started, here are a few things to keep in mind about pruning to avoid damaging your summer lilacs.<\/p>\n
Pruning tools<\/p>\n
Since branches and twigs of varying thickness must be cut when pruning the butterfly bush, you should also have the appropriate cutting tools available.<\/p>\n
Always make sure that the cutting tool is sharp and clean. This not only makes the job easier, but also reduces the risk that you will transmit diseases with tools.<\/p>\n<\/p>\n
Pruning technique<\/p>\n
When doing the actual pruning, be careful not to bruise the shoot. If this does occur, reset the cut below the bruise. Under no circumstances should you continue to cut at the bruised point, as this is an ideal gateway for pests and diseases to enter the plant.<\/p>\n
If the previous year's faded shoots are cut off in the spring, you should<\/p>\n
To remove ground shoots, proceed as follows:<\/p>\n
Note: This slightly angled pruning allows watering and\/or rainwater to drain away better. This serves as protection against fungal infections and other diseases.<\/p>\n
Pruning time<\/p>\n
In addition to the right time in the calendar, there are also some requirements for the right day for pruning summer lilacs. It is best to go to work on a frost-free and overcast day. sunny and rainy days are not suitable for pruning. Since the summer lilac should be pruned very early in the year, the ideal conditions should exist for several days, so that the butterfly bush can recover from pruning.<\/p>\n
To ensure that the butterfly bush thrives vigorously and healthily, perform the following types of pruning on a regular basis:<\/p>\n
Educational pruning is done in the first five years of the butterfly weed's life. The aim of this annual pruning is the formation of a stable framework of older shoots. Because this forms the basis for the budding of the flowering branches.
\nIn the first three years of standing, proceed as follows:<\/p>\n
In 4. and 5. In the first year, proceed as follows:<\/p>\n
Note: "Prune to the tang" means that branches or shoots are not pruned to the base, but left about 10 centimeters.<\/p>\n
With the maintenance pruning you ensure a long life of your summer lily. This pruning method is used from 6. carried out in the first year of growth. This involves cutting the butterfly bush back by half to two-thirds annually in late winter. Its height after pruning should be about one meter.<\/p>\n
With maintenance pruning you can influence the abundance of flowers as well as growth height and width. The stronger you cut back, the stronger the growth and flowering will be. You can get a harmonious growth habit with a homogeneous crown with moderate pruning (topiary); cut deeper and you'll get large, voluminous flower panicles. However, the abundance of flowers is at the expense of the crown, i.e. a homogeneous appearance. Therefore, before pruning, you should consider what goal you are pursuing.<\/p>\n
The following instructions are for the purpose of increased flower formation:<\/p>\n
If the goal is a homogeneous crown, then proceed as follows for topiary:<\/p>\n
During the flowering period, you should cut off faded or. cut off withered flower panicles continuously, as this form of pruning does not fall under the pruning ban. Pruning is done because the withered flowers not only deprive the underlying buds of sunlight, but you also prevent the butterfly bush from putting most of its energy into seed production. To allow the new buds to develop well, cut off the shoot tip to the next bud.<\/p>\n
Tip: In the course of removing withered flowers, you can also cut off overhanging branches up to a side branching.<\/p>\n
The aim of thinning pruning is to prevent the butterfly bush from becoming bare. Causes of thinning may include the following pruning mistakes:<\/p>\n
If the butterfly bush is pruned several times during the season, the base of the bush may become bare, and at the same time there will be more shoots at the tips of the shoots. If the butterfly bush has never been thinned out, it will form branch whorls. These are thick branches that are intertwined and can hinder each other's growth. In addition, you will only see bare, i.e. leafless, branches inside the butterfly bush.<\/p>\n
Another possible cause of callosity is when Buddleja davidii is subjected to vigorous pruning each year. The shrub itself does not suffer from thinning. However, the leafless interior of the bush massively affects its appearance. Therefore, you should regularly thin out the summer lilac. Follow these instructions:<\/p>\n
A rejuvenation pruning will make a puny butterfly bush fit again, because it makes room for a new growth of the shrub. Proceed according to the following instructions:<\/p>\n
In the following years, cut the old butterfly bush like a summer lilac in the first years of standing. Here's how you can slowly rebuild it.<\/p>\n
If you notice significant frost damage to the summer lilac after a severe winter, then you can disregard the general pruning rules. Proceed as follows:<\/p>\n
If you are unsure whether the wood is healthy or frost-damaged, then you can check this with the sog. Check vitality test. To do this, scrape off a small piece of bark. If the tissue underneath is bright and green, then the drive is healthy. If, on the other hand, it is brown, then it is dead wood.<\/p>\n
A disease pruning is done regardless of the season, because after all, you don't want the disease to spread. To avoid this, generously cut off the diseased or infested parts of the plant. It is important to disinfect the cutting tools before and after pruning, because some pathogens remain on scissors, knives and saws for weeks.<\/p>\n
Tip: If the infestation is already far ahead, you should also disinfect the cutting tools in between. This is how you reduce the risk of causing the spread of disease when pruning.<\/p>\n","protected":false},"excerpt":{"rendered":"
