Location and soil



The intense colour play of the Nasturtium needs a natural sunny site. A full sunny location is ideal but it is feeling well in the penumbra also. When it is exposed to too much shade, the creeping plant is searching its way towards the sunny places. The Location at the compost, mostly in penumbra, is therefore also well suited.

Soil condition

There are only a few plants in the garden, which thrive even on a lean ground. The Tropaeolum majus is the best example for this. The leaner the more flowers! It prefers heavy clay soils, especially when these are pro-rata mixed with lime and sand. Furthermore it also thrives as an all-rounder in the strip cultivation with roses or cabbage plants. The Nasturtium basically grows on almost every soil.

Please remember:
  • sunny sites with fertile and slightly damp soils
  • soils that are too sandy and therefore dry soils are unsuitable
  • accumulate sandy soils with compost and soil improvement substances
Use the fresh humus of your compost to improve the quality of sandy soils. In addition you can use peat-free soils, perlite, bark humus or coconut fibers in the interests of environmental protection to improve the soil structure.

Sowing and growing



The Nasturtium scores here again with ease of use. It doesn’t has to be pre-grown very long, but is rather given directly into the open field or the plant pot. To obtain a head start, the first plants can of course be pre-grown in March and then be planted into the open field after the germs. In both cases, choose the date after the Ice Saints, because the small plants don’t tolerate ground frost. Drill a small hole and add two or three of the seeds into it. After that the seeds have to be kept moist but not too wet.

Growing in the patch or bucket

Alternatively, the markets offer ready young plants already after the Ice Saints in May. Now bald spots in the garden can be planted, roses also enjoy the pretty companion. The low-growing varieties of Nasturtiums are ideal to receive a place in the balcony box. The Tropaeolum is germing in the dark. This means that the seeds in the field or in the growing pot are covered with about two centimeters of soil. Already after around two weeks, you can see the first cotyledons.

Planting and repotting

Transplanting the Nasturtiums will be rarely necessary because the fast-growing plant claims a lot of space after some time. Therefore you shouldn’t wait too long after the purchase of young plants to plant them in the garden bed or a larger pot. Also, keep in mind that the plants soon reach a considerable size and the plant pot should be accordingly large should to not upset.


You need a lucky hand at watering the Nasturtium. Because it is necessary that it doesn’t drown in too much water or dries out. The soil should always be kept evenly damp. Here we will see quickly if the soil is too sandy, because then the plants will dry out quick.

  • watering of hanging leaves of the Nasturtium is necessary!
  • watering in the early morning or late afternoon
  • check the moisture content with the finger test before the watering


The Nasturtium is fairly modest and will grow well in the normal garden soil. If you want to eat the blossoms and leaves your Nasturtiums, you should of course only use biological fertilizers – if at all. The ideal fertilization is a portion of fresh humus, which is incorporated in the soil in the spring. If you finish this step some weeks before the date of planting, you will have the best starting point for a Tropaeolum with beautiful bright flowers.

In the balcony box

Depending on whether your Nasturtium has only decorative uses, you can supply the plant with a fertilizer stick or a liquid fertilizer. Pay attention to the manufacturer’s instructions.
