Question: calla lily reproduction
I am a gardening enthusiast and would like to know how I can reproduce the calla lilies… pending a reply, best regards, Lorenzo German
Answer: calla lily reproduction
calla lilies are plants with modified stem, between the above-ground stem and the root system a squat rhizome develops, similar to a large crushed potato; this rhizome can be divided into portions, so as to obtain different plants, which will quickly bloom.
It proceeds when the calla lilies have already bloomed and the large leaves are dried up, or when the rhizomes are dormant; this period depends on the moment in which the calla lilies of the variety you own have bloomed, since the white calla lilies tend to bloom for a fairly long period, which generally ends in the summer, while the colored calla lilies bloom for a different period. This is the period also indicated for repotting and transplanting.
Proceed by extracting the rhizomes from the soil, avoiding damaging them, or ruining the small roots that depart from them; observe the rhizomes, you will see on them some small rounded formations, which in jargon are called eyes. From these formations the future leaves will originate, therefore when you divide the rhizomes you will have to make sure to keep at least one eye for each portion (two would be better); if you are not an expert in rhizome division, it would be advisable for you not to produce a large number of portions, rather divide only each rhizome in two parts. Clean the rhizomes well, if there was some crusted earth you can also wet them in lukewarm water, to practice this operation more quickly and more effectively.
Using a well-sharpened knife (grafting knives are usually used) cut the rhizomes cleanly, leaving, as we said, a pair of eyes for each rhizome.
Dust the rhizomes with a sulfur-based fungicide and place them in small containers, with a good fresh potting soil, at a depth of about 8-10 cm, and place the pots in a sheltered place. When you see the first shoots sprouting from the ground, you can start watering again. The rhizome portions can also be buried, especially if you live in an area with mild winters; only that it is not said that all the portions sprout, and if something should go wrong, the piece of rhizome that does not sprout will remain in the soil to rot, perhaps going to ruin all the other surrounding rhizomes. Keep them in pots until you are sure they have sprouted, then you can place them where you prefer.
It often happens, removing from the ground some rhizomes of calla which have been planted for many years, that lateral formations are noticed, because the rhizome has developed; in this case, it is sufficient to divide the different sections of the rhizome, which is already clearly visible, and place them at home as if they were single plants.
