If you plant nasturtiums in your garden, you will certainly expect them to bloom profusely. And rightly so. It's not for nothing that the large nasturtium with its bright yellow-orange flowers belongs in practically every cottage garden.
Why is my nasturtium not blooming and what can I do?
If nasturtiums don't bloom, it's usually due to too much fertilizer or too little sun. To promote flowering, you should fertilize little or not at all, avoid locations in full shade and remove wilted flowers regularly.
The flower of the nasturtium
The nasturtium flower is not only extremely decorative but also very tasty. Like all other parts of the plant, the flowers also contain mustard oil glycosides, which makes them taste very spicy and somewhat hot. They are also very he althy and are effective against bacteria, viruses and even fungi. Their most common areas of application are respiratory diseases and urinary tract infections.
Why doesn't the nasturtium bloom?
There are actually only two reasons why nasturtiums don't bloom. Either it received too much fertilizer or too little sun. Nasturtiums are quite easy to care for if they are in the right place. It likes a sunny to partially shaded location and rather poor soil. Although it also grows in full shade, it may bloom less profusely there.
What you can do about it
If too much shade is the reason your nasturtium isn't blooming, consider whether you can remedy the situation in some way. It might be enough to prune some branches that are causing too much shade. You may be able to plant your nasturtium in a more suitable location.
If you have fertilized too much, then avoid adding fertilizer altogether in the future. If possible, replace some of the soil around your nasturtium. Use nutrient-poor soil mixed with some clay and/or sand. Nevertheless, you will need a little patience until your plant blooms more profusely again.
You can also support continued flowering by regularly removing spent remains. Then the plant cannot put its energy into maturing the seeds, instead it will produce new flowers.
The most important things in brief:
- fertilize little or not at all
- preferably not in a fully shaded location
- remove wilted flowers regularly
