Care tips

Your care is out of the ordinary in some ways. That doesn't mean callas are difficult to cultivate. If you put together a balanced care package from the following components, the exotic plant will give you a lot of pleasure:

• Water the callas regularly and abundantly while they are in bloom
• Fertilize every 2 weeks from the beginning of budding until flowering, every week during flowering
• At the end of the flowering period, stop fertilizing and gradually stop the water supply
• Winter flowering calla lily in late summer, repot summer flowering plant in spring

Callas spend the rest period, which usually lasts 10 weeks, in a cool, bright place. Indoor plants can stay in the pot, while the flower bulbs are dug up in the bed and stored in a dry, frost-free place.

Which location is suitable?

A light-flooded location suits the sunny disposition of a calla lily. The flowers, however, may not be confronted with blazing midday sun. The plant appreciates warm temperatures of around 20 degrees in summer, while heat waves can impair flowering. During the resting phase it can be a bit cooler, but free from frost. Callas make these demands on earth:

• Nutrient-rich, humic and fresh and moist
• One in the bucket Potting soil compost-based with a handful of sand
