Calla plants have something very special. They are simply a feast for the eyes in the garden and enchant viewers with their beautiful calyxes and bright colors. It's no wonder that many don't get enough of these flowers and want more and more of them in the garden. After all, that's not a problem, because you can easily multiply Callas yourself. Two promising methods are presented here.
Propagate by sowing
The propagation of the Calla by sowing is uncomplicated and actually always successful. However, it takes a few years for flowering plants to develop from the seeds. In spite of this, it is worth growing the Calla by sowing. Here's how you do it:
❶ If you already have one or more Callas, you can harvest the seeds yourself. To do this, detach the grape-shaped seed heads from the plant after flowering and store your yield over the winter. In the spring, the surrounding tissue dries up and the individual seeds can be easily removed.
❷ Then put the seeds of the Calla in a wide growing bowl with moist soil and sprinkle a thin layer of substrate over them. Then cover the bowl with cling film and choose a warm location with temperatures of at least 18 ° C. Water the seeds regularly in the coming weeks.
Vent the bowl for an hour daily to prevent mold growth. If you still discover fungi, remove the infected areas of the substrate and the seeds inside them immediately.
❸ It takes about five to six weeks for the first seedlings to sprout. Wait until you see which specimens are developing best and put these seedlings in individual plant pots.
Propagation by rhizome division
❶ The Calla can easily be multiplied by dividing the rhizome, i.e. the underground tuber. Use a sharp, disinfected knife for this. It is important that both halves of the rhizome have roots and buds.
❷ Now put the halves a few centimeters deep into individual plant pots and set them up indoors. Now you have to water sparingly but regularly.
❸ With the start of sprouting, the fluid requirement increases and you have to increase the watering.
❹ Wait until you are no longer expected to freeze before moving outside. When the ice saints are over, you can plant the Calla in the garden.
