The potted indoor calla will delight flower lovers from May to August with beautiful white, yellow, orange and purple bracts. What you need to know so that the potted plant develops new flowers every year.
How do you care for a calla lily in a pot?
For a he althy indoor calla lily in a pot, a bright location without direct midday sun is ideal. During the flowering period from May to August, the plant needs a lot of moisture and regular fertilization. After flowering, the soil should dry out and the calla should overwinter in a cool place at around 10 degrees. Repotting and renewing the soil take place annually in spring.
Imitating the calla lily life cycle
The calla lily (Zantedeschia) is a swamp plant native to South Africa. In its original location you will find:
- Swampy soil during flowering
- Dryness during the rest break
- Bright location
- Little direct sunlight
In order for the calla to develop many flowers and come back every year, you must provide the potted plant with conditions that correspond to those of the country of origin.
This means that the calla should be very bright during the growth phase, but cannot tolerate direct sunlight at midday. It needs a lot of moisture during the flowering period, but during the resting period it has to dry out completely.
The right location
A bright flower window is the best location for the potted plant as long as it does not receive direct midday sun.
The calla will do very well if you place the pot on the terrace in summer. Make sure the place is protected from the wind.
Zimmercalla likes it warm. White varieties prefer temperatures between 16 and 20 degrees, colored varieties like it a little warmer at 18 to 21 degrees.
The right care
After the rest period, the calla lilies in the pot must be watered slowly and accustomed to the flower window.
During flowering, water abundantly and mist the plant weekly. Fertilize regularly (€8.00 on Amazon).
After the flowering period, the soil must dry out completely and the pot must be placed at around ten degrees during the rest period.
Repot regularly
The calla cannot stay in the same soil for too long. Experts recommend repotting the potted plant every spring. A larger pot is only necessary if the old one has become too small. Wash the planter well beforehand.
The most important thing is to completely replace the soil. The calla is sensitive to viruses, bacteria and mold spores.
Tips & Tricks
Almost all calla species are not hardy and must therefore be kept frost-free over the winter. During the rest period, the calla can remain in its pot. Alternatively, you can also store just the flower bulbs in a cool, dark place.
