Pruning oleanders also needs to be learned. We show when you should prune oleanders and give helpful tips on how to proceed correctly.
The oleander (Nerium oleander) should be pruned regularly so that it remains compact and blooms profusely. Fortunately, the pretty ornamental shrubs also tolerate a good pruning and are not very sensitive. Nevertheless, you should not approach a pruning completely inexperienced.
The pruning of oleanders is quite uncomplicated. However, keep in mind that the buds for the flowers are already established in late summer of the previous year. So cut back the oleander hard to prevent lush flowering the following year. Here you can find out what to consider when pruning the oleander and how you can protect the buds.
When to prune oleanders?
Oleander can be cut at different times depending on the goal. Depending on whether you want to do a pruning or a training pruning, either late fall or early spring is the right time.
Pruning oleanders in spring
In the spring, regular thinning and any training cuts should be carried out. Choose an early time to let the oleander freshly groomed into the growing season. Cut back shoots that are too long to the next shoot instead of trimming the tips of all shoots. At the tips are the buds, which are supposed to eventually develop into flowers. Individual unwanted rungs can also be cut out in this way during the summer. With this measure you promote the crown and prevent the plant from becoming too large. Leave the fruits that appear after flowering, because that's where the buds for the next year are already developing.
Pruning oleanders in autumn
The time for more radical pruning is definitely autumn before moving into winter quarters. Such a strong pruning is necessary when older oleander plants are growing over timebald. To do this, cut the logs down to forty to fifty centimeters. It may look brutal, but you will see that your oleander will sprout all the more luxuriantly afterwards. But the root should be he althy for such a ruthless measure. In the event of weakness, repot the oleander in fresh substrate beforehand to strengthen the roots. Thin and weak branches can be cut down to the base to thin out the base. Pruning may also be necessary for diseased plants. Only prune these plants back as far as the infestation extends.
