If the nasturtium receives too much fertilizer, it only forms leaves, but none or only leaves few flowers. So if you expect a rich bloom from your plant, then you shouldn't "spoil" it too much, but rather keep it sparse. She likes poor, slightly calcareous soil, which can be a bit loamy or sandy, but not too moist.

How and when should nasturtiums be fertilized?
In the open field, nasturtiums should only be fertilized when the soil is extremely poor, otherwise a little well-rotted compost in spring and regular watering in summer are sufficient. However, have you decided to put your nasturtiums in a bucket on the terrace or on the balcony to plant, it needs a little more care and attention.
You also have the choice between different growth forms for the nasturtium for planting in pots, from bushy compact to lush tendrils. Depending on which type of growth you have chosen, the nutritional requirements of the plant are of course very different. This cannot always be adequately regulated via the pot size and the amount of soil available.
If your nasturtium is only used as an ornamental plant, you can give it a small dose of semi-concentrated liquid fertilizer every month. If you like it very comfortably, then use stick fertilizer according to the package instructions. However, if you have your nasturtiums or parts of them eat then you should use natural fertilizers or regularly work a small dose of compost underground.
The essentials in brief:
- In the open field, compost is sufficient in spring
- Fertilize potted plants sparingly
- water abundantly
- Avoid waterlogging
- no chemical fertilizer for crops
Tips & Tricks
Use the fertilizer sparingly. If you fertilize too much, your nasturtiums will not produce more but fewer flowers.
