A Nasturtium doesn’t need much to be happy. Nevertheless, the right location and the optimal time for planting are crucial for abundant flowering. They are also likely to be infested with lice, but you can prevent this by planting correctly.
The best floor
If the nasturtium is on poor soil, it will bloom profusely. On the other hand, if the soil is very nutrient-rich, the leaves benefit, but you have to do without flowers. A loamy and if possible also calcareous soil is ideal for your nasturtium, it can also be a little sandy.
The right location
Nasturtium is fairly undemanding. It even grows quite well in the shade and pleases with its colorful flowers there. However, given the choice, it would prefer a sunny location.
Since it grows quite luxuriantly and likes to climb, it needs a lot of space. A climbing aid can show her the direction of growth. This can be a decorative trellis or a simple fence.
The best planting time
Since the nasturtium is not hardy, it should only be planted outdoors from around mid-May, when the ice saints are over and the danger of night frosts is over. If you have decided on a small variety that you want to put in a planter, then you are of course independent in terms of time.
However, you should then ensure a frost-free location. The nasturtium does not survive the first frost, which is why some plants are often mistaken for annuals.
The easiest way to propagate nasturtium is by seed. You can get these in nurseries and specialist shops, but also in supermarkets. You can also collect the seeds of your own plants when they have finished blooming. Sowing can be done directly outdoors after the ice saints.
Nasturtium can also be propagated by cuttings. Immediately after cutting, plant your cuttings in a pot with potting soil and place this pot in a warm place. For rooting, the plants need temperatures of 20 to 25 °C (68-77 F) and about a week.
Nasturtium as a lice catcher
Not only humans but also aphids love nasturtiums. You can take advantage of this by planting nasturtiums between your roses, for example. Then the lice will probably populate the nasturtium and spare your roses.
Nasturtium can also perform this service in cabbage beds. However, this makes the plant almost useless for your own consumption. For this purpose, you should plan some plants in another location.
If you have enough seeds, sow nasturtiums between your roses as a lice catcher.
