The ideal care for the room calla
The so-called Zantedeschien are sold in various subspecies in pimped form as Zimmercalla in the trade. Since these plants are originally swamp plants, the location requirements of a room calla usually resemble those of the likewise very popular dragon tree.
How often should a room calla be poured?
As a houseplant, a room calla is not really subject to a climatic change of seasons. The need for water and nutrients therefore depends more on the flowering time of the plant. During the flowering period, a calla in the room should always be poured regularly and thus kept evenly moist. On the other hand, the following applies to the time after flowering: The water supply should then be reduced to such an extent that it simulates a dry season and thus induces a certain amount of rest in the plants.
What should be considered when repotting a room calla?
In order to avoid accumulation of certain nutrients in the substrate, a room calla should be repotted once a year at the end of its "resting phase" and be supplied with new plant substrate. The required soil itself can be mixed with nutrient-rich humus and ordinary sand. The pot only needs to be larger if the room calla has grown significantly. It is in any case advantageous to introduce a drainage layer into the lower part of the pot as protection against waterlogging at the roots, such as in the case of the princess flower.
How is the room calla properly cut?
This plant does not have to be cut, only regularly dead plant parts are disposed of. If a room calla becomes too big for its pot over time, it can also be shared for propagation purposes.
How can the room calla be protected from pests?
Occasionally, a room calla is attacked by aphids and spider mites. The latter can be prevented by providing a high level of humidity in the room or by occasionally spraying calla leaves with lime-free water.
What can be done against diseases of the room calla?
Viruses, bacteria and fungal infections rarely play a role in a room calla. Rotting symptoms 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 room calla should not only be kept fairly dry during an approximately eight-week period of rest, but also not be fertilized. With the beginning of the new flowering period can be fertilized 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, similar to the dragon tree, room callas should not be placed directly over a radiator, otherwise their roots may dry out. However, during the resting period, usually over the winter, the plants should optimally be placed in a cooler room at about 10 to 15 degrees Celsius room temperature.
Tips
As a precaution, wear gloves during all care measures at a room calla, as the indoor plant, which is dangerous for children and pets due to its toxic content, can sometimes cause skin irritation even after mere contact.
