Rhododendrons are among the most popular garden shrubs among Germans.

A cut is part of the maintenance every now and then.

But how and when is it necessary?

A rhododendron * needs to be cherished and cared for - after all, it is a real feast for the eyes in German gardens.

But you shouldn't overdo it: especially in the first few years you hardly need to trim your rhododendron.

The evergreen shrub is still in the development phase, in which you should not disturb it.

The first

care and cutbacks

are then necessary with increasing age.

When can I cut a rhododendron?

When to cut your rhododendron depends on the purpose of your project.

A simple maintenance cut is usually carried out after flowering from May to June.

However

, if you

want to

trim

the plant a

bit

because it has become

bald inside

, you should do so before it blooms in autumn or spring.

According to the garden journal, the

following

plant and training

prunings are common for rhododendrons:

  • Trimming

    : You encourage the growth of new buds, for example by removing dead flowers.

    The date for this is after the flowering period.

  • Maintenance pruning

    : You remove individual shoots that have either become bald or are growing unfavorably.

    This is done in the spring before flowering.

  • Rejuvenation cut

    : You breathe new life into an old rhododendron through a cut.

    Best late in winter by March 1st.

  • Build-up pruning

    : After rejuvenation or a radical pruning, you encourage new growth.

    The date is before the flowering period in spring.

Cleaning up: This is how the "care cut" works on the rhododendron

After the flowering period, the

withered flowers are

not a pretty sight.

You can use this opportunity to "clean up" something.

You don't even need pruning shears or special tools.

Simply grasp the small piece of shoot under the withered flower with your thumb and forefinger and break it off to the side.

So the rhododendron is not only nicely cared for, but you also give the new buds more air for the next budding.

Conservation pruning on the rhododendron - tips

When the first balding branches protrude from the rhododendron or a branch protrudes unfavorably, it is time for a maintenance cut.

To do this, take the branch in question and check whether there is still a young, unbranched shoot far down on it.

There you then start

the cut at the fork of the branch and side branch

, as the gardening journal advises.

You should leave a small cone of five centimeters with a leaf on the side.

How to make the taper cut or radical cut on the rhododendron

A

rejuvenation or radical cut

is only required for an old rhododendron that you want to breathe new life into or that has even partially dried up.

However, it is important that grafted plants usually do not cope with too much pruning.

You don't have to worry too much about rhododendrons that have been propagated by cuttings.

You should also make sure that the evergreen flowering shrub is really well rooted.

In doing so, you cut the branches of the rhododendron down

radically to a length of 30 to 50 centimeters

, as advised by the My Beautiful Garden portal.

So-called sleeping eyes sit on the woody shoots, from which new buds form and sprout again after pruning.

In order not to put too much strain on the plant, you should divide the rejuvenation pruning over two years - i.e. only work on half of the branches in the first year and the rest in the next.

You can cut branches as thick as your arm with a pruning saw, as the stumps also produce new shoots.
