The black nightshade is not particularly popular in most gardens. The plant, which is related to the potato, is considered a weed, grows quickly and spreads on its own even on fallow land and on the edges of fields.
Is the black nightshade harmful in the garden?
The black nightshade in the garden is a poisonous annual plant that grows up to 70 cm high. It should be removed before it flowers to prevent spread. It is not recommended in family or animal gardens.
How and where does black nightshade grow?
The black nightshade grows almost everywhere, but preferably on nitrogen-rich clay soil. You can find it on the edges of fields and paths, on walls and on rubble sites. He also likes to settle in the garden. Since it multiplies quickly and abundantly there, it is considered a weed. The annual herbaceous plants usually grow up to 70 centimeters high, and in good conditions up to one meter.
Is the black nightshade poisonous?
Black nightshade contains tannins and alkaloids, including solanine, which is also found in potatoes and unripe tomatoes. The concentration of the ingredients varies greatly, but some parts of the plant can be classified as poisonous to very poisonous, especially the herb, the leaves and the seeds.
Unripe black nightshade berries are also considered poisonous, while ripe ones (without seeds!) are sometimes considered edible. However, we strongly advise against consuming it, as poisoning can be fatal. The quantity responsible for this varies greatly and cannot be reliably classified.
How do I remove black nightshade?
As a rule, the black nightshade is removed mechanically, i.e. by tearing it out or mowing it down. Both methods are successful. However, it is important that you remove it before it bears fruit and they fall to the ground, ideally even before it flowers. Otherwise new plants will grow there next year.
Fighting black nightshade with chemicals does not make sense. Since it is related to potatoes and tomatoes, appropriate products would also harm these plants. That might not be in your interest.
The most important things in brief:
- toxic to humans and animals
- not suitable for family gardens
- annual plant
- herbaceous growth
- mostly up to 70 cm tall
