  • Chop up the shells
  • Let the pieces dry well
  • Work dry pieces into soil around the plant
  • alternatively, let the bowls soak in water

frequently asked Questions

Even after fertilization, my plant does not produce flowers, why?

If the plant is still blooming after fertilizing, it may be because it was grown from seeds. Then the lily is just too young. Wait for the next year, when the decorative flowers will certainly show up.

When and how should I fertilize my ornamental lilies?

The first fertilization always takes place at the time when the plant is allowed to move outside again from its winter quarters. You should then pay attention to regular but economical fertilization, which should be carried out every three to four weeks during the growing season.

Can I water my ornamental lilies with mineral water?

Carbonated or still mineral water is ideal for watering the plants. Because they get the minerals that are in them at the same time. But not every sparkling water is also mineral water at the same time. This is obtained from sources and must be titled accordingly. Otherwise it is table water that is bottled from the pipes. You should shake the water well before watering so that it no longer contains carbon dioxide.

Can I always use the same home remedy for fertilization?

That is not recommended. Because in such a case it could easily lead to an overdose of various nutrients. It is better if you fertilize the agapanthus more often with changing organic fertilizers that you can find in the list. Therefore, you should not only use the potassium fertilizer too often, but also a mixture of phosphorus, potassium and nitrogen more often.
