The nasturtium is a real all-rounder: it thrives in the bed, in the balcony box and in the bucket. But only if you give her the right care.Nasturtium is very undemanding
Depending on the variety, the nasturtium grows rather flat or climbing, but always very quickly. The brightly colored flowers bring a lot of color into the garden and on the balcony. What many do not even know: the flowers are edible! As a tasty decoration, they fit on delicious baked goods and also in salads.
So that the nasturtium develops many flowers, of course, you have to help a little. A lot of care is not necessary, but the grateful nasturtium can not do without it.
Choose the right location
In order for your nasturtium to find ideal conditions, you must plant it in the right soil at the right location (reading tip: plant nasturtium - this is how you can grow it indoors and sow it in the garden). In terms of location, the nasturtium is generally not particularly picky. However, it should best be in the sun or partial shade. The plant also grows in the shade, but then it produces fewer flowers.
Also put the nasturtium in humus-rich soil. If the soil is too lean, enrich it with potting soil or compost. The substrate should always be moist, but not wet. Commercial potting soil is best suited for tubs and window boxes.
How to properly pour the nasturtium
The nasturtium has a high water requirement. The earth must therefore never dry out completely. On very hot summer days, it is best to water in the morning and in the evening. Because if the plant gets too little water, it leaves the leaves hanging. Lime-free water or rainwater is the best choice. If you have a pond, pamper the plant with a pot of pond water every now and then. This gives it a lot of nutrients.
You must take this into account when fertilizing
The nasturtium generally does not need a special fertilizer. If you have enriched the soil with compost before planting, this is usually enough for the annual plant. You can supply nasturtiums in boxes or buckets with fertilizer sticks, but please be very moderate. Too much fertilizer causes the leaves to grow predominantly. The green carpet of leaves looks beautiful, but actually the flowers are what makes the plant so special. The rule of thumb applies: nutrient-rich soil yes, too much additional fertilizer no if you want to have a lot of flowers.
Remove faded parts and seed pods regularly
Remove faded parts and seed pods regularly. Then the plant has enough strength to produce new flowers all summer long. If the nasturtium grows too much, just cut a few shoots, this will not harm the plant at all.
You can ripen some seed pods towards the end of summer. This is the basis for planting nasturtium next year. If you want the nasturtium to thrive again at the same location, you don't really have to do anything. Seeds that remain on the stems also sow themselves. Then the nasturtium grows again in the same place in the new year.
By the way:
Not only the flowers are edible, but also the seeds. If you're looking for a cheap alternative to capers, just soak nasturtium seeds in vinegar. You will hardly notice a difference in taste.
