When, how often and how is it done?

How often do you have to repot oleander?

The oleander is a heavy eater, i. H. it needs a lot of nutrients and therefore not only has to be fertilized regularly, but also supplied with fresh soil. Since the shrub also grows very quickly and - depending on the variety - can be very tall and wide, it also needs a new, larger planter every year - at least if it is a younger plant. Older specimens, on the other hand, only need to be repotted every five to ten years, here it is sufficient to pour new soil into the existing container every spring instead. Ergo you should

young, not yet too large oleanders annually
and older, hard-to-handle specimens every five to ten years

When is the best time of year to repot the oleander

The best season for repotting the oleander is spring, if possible as soon as possible after clearing out of the winter quarters. You can also combine this measure with a pruning of both the upper parts of the plant and the roots. Make sure you keep the freshly pruned and repotted plant before eventual Protecting late frosts - even an oleander that has just been fetched from the cellar does not belong in it right away blazing sun. In principle, however, the oleander can be repotted for the whole season until it is placed in the winter quarters, if necessary.

What kind of soil should I use to repot oleander?

Although the oleander needs a lot of nutrients, but - typical for many Mediterranean plants - tolerates no humus rich soil. Therefore do not use a commercially available one Potting soilbut mix the substrate yourself if possible. To do this, mix them together

5 parts of potted plant soil
1 part clay or Clay powder
1 handful of garden lime

and, if you repot the plant in spring, a good one Slow release fertilizer for flowering plants. Alternatively, you can also use potting soil as well as conventional, clayey ones Garden soil Mix in a ratio of 1: 1 or buy a substrate that is specialized for Mediterranean potted plants.

Which pot to use for oleanders?

Oleanders need one rather wide than deep planter, which is twice as large as the root ball, if possible. After all, there should be plenty of water to be stored there during the hot summer months, In addition, the roots need space for their growth - the more beautiful the plant grows and blooms above. Which material you use is entirely up to you; It is only important that the pot has drainage holes on the bottom and is also in a deep saucer.

Repot the oleander - this is how it's done

Then, however, you should use the plant also prune above ground accordingly.
This measure promotes the growth of the oleander.
Now mix the substrate according to the recipes described above
or fill in the ready-made substrate mixture for Mediterranean potted plants.
Do not forget to mix in the slow release fertilizer.
Put the oleander in and water it well.
In the following period he must be supplied with water particularly carefully,
because this promotes the formation of new roots.
Make a plant cut and remove oversized shoots
as well as overaged, dried up or frozen parts of the plant.

By the way, with oleanders you can do without the drainage layer otherwise necessary for potted plants, because these plants do not harm “wet feet” at all - on the contrary. However, you should cover one of the drainage holes in the bottom of the pot with potsherds so that the freshly filled soil is not washed out.

Tips and tricks for repotting very large oleanders
