Fargesia murielae, umbrella bamboo, Muriel bamboo
The fact that the garden bamboo can grow very luxuriantly is just one reason to cut it regularly. In general, the appearance of Fargesia murielae can be enhanced in this way. However, a prerequisite for optimal growth after the cut is timing the right time. But when did this come?
Regular pruning
Fargesia murielae is known to cope well with even radical pruning. In fact, it makes sense to use pruning shears every now and then to:
- produce a denser, more compact growth
- give the garden bamboo a handsome shape
- curb growth
- remove bare branches
- remove diseased branches
- provide more light
- rejuvenate the bamboo
types of cuts
In contrast to numerous other shrubs, the bamboo is not only radically shortened once. Over time, cuts of different strengths are recommended at different times. There are three types of cuts:
- the grooming cut
- the cutback
- the topiary
care cut
The trimming is usually done twice a year and is primarily done on bamboo hedges. On the one hand, he serves the shape retentionby removing overhanging branches and bare twigs. On the other hand, the better light supply through thinning out ensures denser and bushier growth. The side shoots are also shortened for this purpose.
pruning
Garden bamboo requires one every four to five years rejuvenation, cutting it back radically to 20 cm above the ground. Anyone who fears cutting their shrub too much in this way will be amazed at how quickly it recovers from the pruning. After a short time, the bamboo rewards the effort with an intensive, dense growth.
topiary
The topiary plays a major role, especially when keeping bonsai. Fargesia murielae is a very fast-growing plant, which is why a shaping cut is regularly necessary to maintain the appearance. Fortunately, the plant allows the gardener to let off steam artistically as he pleases.
young plants
In the first few years, however, you should refrain from any form of cutting, as the leaves first have to develop completely. This is important for the bamboo to photosynthesize. In the process, it converts oxygen, light, and water into sugar and glucose, which it uses to fuel its growth.
time
So that the grass recovers well from cutting, the right time is of great importance. Although the various cuts are sometimes carried out more frequently, sometimes less frequently, they should always be done at the same time of year.
First correction cut
A garden bamboo sprout in spring. In order not to damage the new leaf green, the first correction cut must be made beforehand. in the March is the ideal time to cut the grass. First, only the protruding side shoots are shortened.
main cut
Since bamboo grows rapidly, an annual trimming is not enough to keep its shape. At a later point in time, a radical pruning is essential. In order to save as much work as possible, you should start this after the leaves have sprouted. The unfolding of the side branches serves as a reliable indication that it is time for the main cut. The date of the intervention also depends on the climatic conditions. In colder areas it should happen a little later, after the Ice Saints. It is possible earlier in warmer regions.
Although the main cut greatly shortens the plant, it soon sprouts again and reaches the usual height in a short time. In order to create the desired shape, the radical pruning is followed about a month and a half later by a shaping cut in which the new shoots are adapted to the original growth form. Again, the temperature is crucial. If the bamboo is not cut until May, the second cut can still be made in June.
Bamboo in the bucket
The natural growth form of the garden bamboo rises up. Nevertheless, the grass is becoming increasingly popular as a bonsai culture or container plant. In contrast to using it as a hedge plant, several topiary cuts are then required throughout the year. Not only leaves but also roots have to be shortened. The latter is recommended in the course of repotting.
Special case: Ground-covering species
Some types of bamboo are used as ground cover in the garden. However, under the local weather conditions, they sprout later than the usual Fargesia murielae. Accordingly, the cut is also shifted backwards.
Cutting after frost damage
At temperatures of -20°C, frost damage can occur, which manifests itself in brown leaves and twigs. Most often, the symptoms become visible in February. Nevertheless, despite the bleak appearance, the gardener should not immediately grab the scissors, but should wait for the regular pruning date in June. The plant may recover on its own. Only when no new roots have formed in summer does a radical cut help new shoots.
tip: The garden bamboo is so popular because there is no risk of disfiguring it with a too radical pruning. Even after intensively shortening the shoots, they will sprout again after a short time and close unaesthetic holes. This allows the gardener to let his imagination run wild and try out different forms of design. Thanks to this property, the grass is also ideal for keeping bonsai. However, there are different types of bamboo that have different growth rates. Accordingly, the gardener should adjust the intensity and frequency of pruning for each variety.
