Cut off oleander flowers: Should you remove faded flowers and pods or leave them until winter?

The oleander is a woody plant that loves to bloom. With good care, its flowers delight the eye of the amateur gardener all summer long. But when the plant begins to fade in August, then the question arises: can you still extend the flowering period? Perhaps cut off the oleander flowers? We explain whether removing the faded along with the pods really achieves the desired effect.

Cut oleander flowers: When is it a good idea to remove what has faded?

Cut off oleander flowers or leave them after they have withered

Oleander is a heavy grower that grows very quickly. So it’s no wonder that after just a few years, the blooms start to dwindle. In this case, a nurturing pruning is necessary. By the way, this applies not only to the garden plant, but also to the container plant.

Normally, pruning is done in the fall, just before the plant is brought to the winter quarters and before the winter dormancy period begins. However, only the older shoots are removed. In August, the oleander has already formed the new flower buds. If these are cut off, it will not bloom next year. Therefore, in September, the plant is only thinned out a little and not completely cut back close to the ground.

If the oleander has old flowers from the previous year: Cut it off or leave it?

Oleander as a tub plant care useful tips

Regular pruning saves a lot of time and effort in the fall. Flower buds from the previous year that have not opened are best left standing. However, you should remove dried out flower buds. Instead of cutting them off, pluck them off.

Should you cut off faded flowers?

You don’t need to cut off the flowers either. It is completely sufficient if you pluck off only the petals. One shoot bears many inflorescences, which bear new flowers one by one. Therefore, in any case, do not cut or shorten the flower shoots – at least until the end of the flowering period, which, with good care, can be extended until the end of September.

The oleander has long pods: remove or in any case do not cut?

Cut off oleander long pods or do not remove them

The first pods of the oleander appear in August. The long fruit capsules (about 10 to 15 cm long) contain the seeds of the plant. After a ripening period, the seed pods burst open, releasing the seeds. The oleander uses too much energy to form the pods. This can weaken it and make it more susceptible to pests and diseases . Therefore, cut off the pods regularly. In this way, you can also encourage flower formation.

Encourage flower formation and extend the flowering period by pruning with care in summer.

Do not remove flower buds from the previous year

It is possible to promote flower formation through a nurturing pruning. Older plants in particular form many inward-growing, sickly shoots. For this, the oleander wastes a lot of energy that it actually needs for flower formation. The sprouting weakens the tub plant and the flower formation decreases. But if you regularly cut off these shoots, then the oleander can put its strength into the flowers.
