The so-called Zantedeschien are sold in different subspecies in potted form as indoor calla lilies. Since these plants are originally marsh plants, the location requirements of a room calla are usually similar to those of the dragon tree, which is also very popular.
The indoor calla needs attention, especially during the flowering period
How often should an indoor calla be watered?
As a houseplant, an indoor calla is not really subject to a climatic change of seasons. The water and nutrient requirements are therefore more dependent on the flowering period of the plant. During the flowering period, a calla in the room should always be watered regularly and thus kept evenly moist. On the other hand, things are different for the time after flowering: Then the water supply should be reduced to such an extent that a dry season is simulated and a certain rest period is induced in the plants.
What should be considered when repotting a room calla?
In order to avoid accumulation of certain nutrients in the substrate, a calla lily should be repotted once a year at the end of its "dormant phase" and provided with new plant substrate. The required soil can be mixed from nutrient-rich humus and ordinary sand. The pot only has to be chosen larger if the room calla has really grown significantly. In any case, it is advantageous to place a drainage layer in the lower part of the pot to protect the roots from waterlogging, as is the case with the princess flower, for example.
How is the calla lily cut correctly?
This plant does not actually have to be cut, only dead parts of the plant are disposed of regularly. If a room calla becomes too big for its pot over time, it can also be divided for propagation purposes.
How can the room calla be protected from pests?
Occasionally, a calla lily is attacked by aphids and spider mites. The latter can be prevented by ensuring high humidity in the room or by occasionally spraying the calla leaves with low-lime water.
What can be done against indoor calla diseases?
Viruses, bacteria and fungal diseases only very rarely play a role in a room calla. Signs of rot on the leaves or roots are usually directly related to care errors such as waterlogging in the substrate.
How often and with what should a room calla be fertilized?
After flowering, the indoor calla should not only be kept fairly dry for about eight weeks, but should also not be fertilized. With the beginning of the new flowering period, you can fertilize every 14 days, later weekly with a suitable plant fertilizer. But be careful not to over-fertilize the plant in the pot.
Does a room calla need special care in winter?
In general, indoor callas, similar to the dragon tree, should not be placed directly above a radiator, otherwise their roots can dry out. During the dormant phase, which is usually inserted over the winter, the plants should ideally be placed in a cooler room with a room temperature of around 10 to 15 degrees Celsius.
tips
As a precaution, wear gloves for all care measures on a room calla, since the houseplant, which is also dangerous for children and pets due to its poisonous content, can sometimes cause skin irritation just by touching it.
