The indoor calla is native to South Africa, where it grows in swampy regions that dry out after flowering. It needs optimal location conditions and the right care if it is to develop many flowers. How to make your calla lilies bloom.
Why is my calla lily not blooming and how can I get it to bloom?
To get a calla to bloom, it needs a bright location without blazing midday sun, regular fertilization during the flowering period, sufficient water and a rest period with dry soil after flowering for the development of new flowers.
Causes why the calla doesn't bloom
- Bright sun
- Soil too poor in nutrients
- Soil too rich in nutrients
- Too little water
The calla doesn't get blazing sun; the leaves especially suffer from direct midday sun. In a favorable location it is only in direct sun in the morning and evening.
Room calla needs very moist soil during the flowering period, but it must be very dry during the resting period. This is the only way the bulbs can gather enough strength to develop new flowers.
Helpful tips to get the calla lilies to bloom
- Bright location, no midday sun
- Replace Earth
- Fertilize
- Water a lot during flowering
- Let the soil dry out after flowering
Do not place the plant in the flower window directly behind the window. The glass heats up the leaves so much that they burn. Sometimes a light sunscreen that you place in front of the plant during midday helps. Under no circumstances should the place be too dark.
You should replace depleted soil and repot the plant. Fertilize once a week during the flowering period and ensure that the soil is always moist in summer.
During the flowering period, the calla needs a lot of water. Even waterlogging doesn't harm you. In addition, you should spray the plant at least once a week with a flower sprayer (€7.00 on Amazon) to increase the humidity.
Keep dry while resting
After flowering, stop watering and let the flower bulb dry out over the winter. Only then can the plant gather enough strength for the flowers next year.
Tips & Tricks
In summer, the calla is better off in a pot on the terrace. Place them as brightly as possible. In a favorable location, the plant only receives direct sunlight in the morning and evening.
