Plant rhododendrons

Plant rhododendrons

Rhododendrons should always be planted between the end of February and mid-May, and then in a partially shaded spot, which may also be close to deep-rooted trees or other large shrubs. The perennials grow best in moderately humus rich, slightly moist soils, which can be easily loamy or sandy.

All rhododendrons are extremely sensitive to compaction, which is why you should often loosen or mulch the soil around the plant. Consideration must be given to the fine roots close to the surface.

For optimal care of the rhododendrons, of course, the regular watering of plants, but no waterlogging may arise. Even in extremely dry winter phases, you should supply the Alpenrose with minimal water.

➤ Pruning:

Maintain rhododendron

In general, a pruning of rhododendron plants is hardly necessary. Only the withered flowers should be cut off in the spring.

However, as soon as old plant shreds start to corrode from below, a so-called rejuvenation cut should be made. The ideal time for this is the early spring or autumn. The plants must be cut back to about 50 centimeters in height. Incidentally, you can do this tapering cut even in the case of lack of space.

➤ Fertilization:

Also for this purpose, the specialized trade now has very special rhododendron fertilizer ready, which you should give the perennials, especially during the growth phase. Ideally, the use of a long-term fertilizer, which dispenses its active ingredients to the plants over a period of about 3 months. It then suffices to apply twice a season. Otherwise, you will need to apply fertilizer at intervals of four to six weeks.

➤ Pest Control:

In case of leaf spots (fungal disease) you should remove the affected, discoloring leaves as quickly as possible from the rootstock. All other pest infestations (for example with the rhododendron cicada) can usually be combated with appropriate pesticides. But then you must absolutely consider the instructions and warnings of the respective manufacturer!
