Incorrect care can punish the oleander with missing flowers. We show what you can do when the oleander is not in bloom.

If the oleander does not have any flowers, this can be related to the maintenance

The oleander (Nerium oleander) should be overflowing with flowers. But what if he doesn't do that? What could be the reason if the oleander does not want to unfold its splendor, and what can you do about it? The oleander is actually known for its abundance of flowers. Nevertheless, under certain circumstances it can happen that it does not bloom or only blooms a little. This is usually caused by an error in maintenance.

Oleander not blooming: location as the cause

The most common cause is a lack of heat and light. The oleander needs a lot of sun and warmth. Therefore, first of all, check the location of your oleander. Try a slightly sunnier place, ideally in front of a house wall or stone wall. The stones heat up during the day and radiate heat back, especially at night - just the thing for the oleander.

Too much fertilizer hinders blooms

If this cause has been ruled out and the location is actually optimal, then it could be that you fertilize your oleander too much. In this case, the oleander puts more energy into vegetative growth, leaving less for flowering. Over-fertilization can also often be recognized by brown leaf edges, for which an excess of nitrogen is responsible. In this case, repot your oleander so that it gets fresh and nutrient-poor substrate such as potting soil.

Potting fresh soil can help the oleander

In general, make sure that you use fertilizer with a balanced nutrient ratio. Long-term fertilizers such as our Plantura organic flower fertilizer are easier to dose because they only have to be given every two to three months.

Accidentally cut off flower buds

Another reason could be pruning. The buds for the flowers are already created on the tips of the shoots in the previous year, even before the seeds have matured. If you then clipped the tops, you might accidentally pluck the budshave cut off with. We have summarized for you here how to properly prune your oleander.
