With these instructions, you can also plant a rhododendron correctly. There are also plenty of care tips.

In many places we find beautiful blooming rhododendron shrubs in the gardens, which unfold their true bloom every year in spring (from around May) and enchant us with their appearance. If you want to plant a rhododendron, you should read this advice article including instructions and care tips carefully, because a little effort is necessary so that the rhododendron can grow healthy and, above all, bloom.

Planting rhododendron - Instructions

The following step-by-step instructions explain exactly which preparations have to be made before planting in the garden and how you can put the rhododendron in the ground.

    Select location

    Most rhododendron species prefer a sunny to half-shady location, preferably protected. The planting should therefore not take place in a windy place in the garden.

    Prepare the soil

    The preparation of the soil is a basic requirement for lush growth. The soil should be loose and acidic, the pH value between 4.2 and 5.5 in the best case. Use special rhododendron soil or add acidic peat to the soil.

    Dig out the planting hole

    The location has been found and the ground prepared, then it is time to insert the rhododendron. Dig a planting hole that is at least twice as wide and as deep as the root ball of the plant.

    Plant rhododendron

    Depending on the condition, the root ball can be soaked in water before planting. Place the plant about so deep that at least 3 cm of the surface of the bale is below the surface of the earth. If you haven't already done so, mix the excavation with peat, fill the planting hole again and step on everything.

    Water rhododendron

    The main work is now done, at the end draw a watering trough around the plant and water the freshly planted rhododendron thoroughly.

" Important: When planting several rhododendrons in the garden, you should make sure that the plants are not too close together, otherwise they will hinder each other's growth.

When is the best time to plant rhododendron?

It is best to use rhododendrons in the period from Late February to mid-May plant, and then in a partially shaded location, which can also be near deep-rooted trees or other large trees. The perennials grow best in moderately humus, slightly humid soils, which can easily be loamy or sandy. Since the rhododdendron is hardy, you can too in autumn - early September to mid November - plant outdoors. The planting of pots is possible all year round, but then the rhododendron needs winter protection.

Grooming rhododendron - 5 tips

The rhododendron is actually very easy to care for, at least for plants that have been in the soil for a few years. From time to time, however, care measures are necessary, which you should not neglect.

    Loosen the earth

    All rhododendrons are extremely sensitive to compacted soil, which is why you should often loosen or mulch the soil around the plant. You have to be considerate of the fine roots near the surface.

    Pour rhododendron

    For optimal care of the rhododendrons, it is of course also important that the plants are watered regularly, but no waterlogging should occur. Especially in extremely dry winter phases, you should provide the Alpenrose with minimal water.

    Cut rhododendron

    A pruning of the rhododendron plant is generally not necessary. Only the withered flowers should be cut off in spring. However, as soon as old plant perennials balk from below, a so-called rejuvenation cut should be made. The ideal time for this is early spring or autumn. Cut your rhododendron either before or after flowering. You have to cut the plants back to a height of about 50 centimeters. You can also carry out this taper cut if the rhododendron has become too big for you.

    Fertilize rhododendron

    For this purpose too, the specialist trade now has very special rhododendron fertilizers available, which you should give to the perennials, especially during the growth phase. The ideal is the use of a long-term fertilizer, which doses over a period of about 3 months, releases its active ingredients to the plants. It is then sufficient to use it twice a season. Otherwise you must fertilize every four to six weeks.

    Pest control

    In the case of leaf spots (fungal disease), you should remove the affected, discolouring leaves from the planting stick as quickly as possible. If pest infestation occurs, for example due to the rhododendron cicada), this can be combated with pesticides. Be sure to read the instructions and warnings from the respective manufacturers!

    Achtung But be careful: Many rhododendron species contain toxins that are found in the leaves, flowers, fruits and pollen.
