How to properly care for rhododendrons


The right location is important for rhododendrons to thrive. The location should be bright, but not in the blazing sun. A location under deep-rooted trees such as e.g. Pine trees. When it comes to planting, you should put the rhododendron in a hole that is twice the size of the root ball. The bale surface should be at the level of the earth's surface, so do not set it too low.

To water:

Sun and high temperatures can be very difficult for the rhododendron. So when it is really hot outside and when the rhododendron has a place in the blazing sun, you have to water it regularly and abundantly. If the rhododendron rolls up its leaves, it wants to prevent evaporation. This is a sure sign that he urgently needs water.


If you want to do something good for your rhododendron, fertilize it regularly with a rhododendron fertilizer from March onwards (pay attention to the manufacturer's instructions). Alternatively, you can also use compost.

It also makes sense to apply mulch around the plant. It keeps the moisture better in the soil and thus protects the rhododendron from drying out. It also releases nutrients into the soil and protects the roots from excessive sun exposure.

To cut:

As such, you don't have to cut the rhododendron. Rhododendrons can grow quite large, which is not welcome in every garden. Then you even have to use the secateurs and cut the rhododendron. It is best to do this in autumn right after flowering. Shorten about a third of the shoots evenly to about 50 centimeters.

Remove withered flowers:

Inflorescences that have withered should always be broken out immediately, as it takes too much strength for the plant to produce seeds.


The rhododendrons available here are usually all hardy. So you don't have to make any winter arrangements here. The only exception are rhododendrons in the bucket. You definitely need some protection in winter. It is best to place the container plants in a bright but cool place in the house. Does the plant have to hibernate outside because the bucket e.g. has become too heavy, then surround the pot with insulating materials such as Coconut mats or bubble wrap.

The root ball should never dry out completely even in winter. So you have to water the rhododendron even in winter. Always do this on a frost-free day. Do not water too much, because if it freezes at night, a large lump of ice forms in the root area.
