Propagation of Celosia globosa Schinz var. porphyrostachya C.C.Towns.
Celosia globosa Schinz var. porphyrostachya C.C.Towns. can be propagated through various methods such as:
Seeds
Propagation of the plant through seeds is the most common method. It is recommended to sow seeds in moist soil during the spring season. While sowing, make sure to keep the soil moist, not wet. Seeds should be covered with soil with a depth of roughly 1/8 inch. Keep the sown seeds in warm and bright light conditions and germination occurs in 5-7 days.
Cutting
Cuttings from mature plants can also be used for propagation. This is usually done in late summer or early fall. The cuttings should be taken from non-flowering shoots and should be 4-6 inches long. The lower leaves should be removed, and the cuttings should be dipped into rooting hormone and planted in a mix of peat moss and sand. The cuttings should be kept in a shaded area with high levels of humidity for two to three weeks, and then gradually acclimated to a sunny area.
Division
Another way to propagate the plant is through division. This method is usually done to maintain the size of the plant. The clumps of Celosia globosa Schinz var. porphyrostachya C.C.Towns. are divided into small portions and replanted in individual pots or areas.
