Propagation of Puelia dewevrei De Wild. & T.Durand
Puelia dewevrei De Wild. & T.Durand can be propagated through various methods which include:
Seeds
The most common method of propagation for Puelia dewevrei De Wild. & T.Durand is through the use of seeds. The seeds should be collected from ripe fruits and sown immediately in a well-prepared soil mixture. The germination rate of the seeds is relatively low, but with proper care, the success rate can be improved. The ideal substrate for germination should be well-draining and kept consistently moist. It is also important to provide the seeds with a warm environment with temperatures above 20°C. The seedlings should be transplanted into individual pots after they have grown two or three pairs of leaves.
Cuttings
Puelia dewevrei De Wild. & T.Durand can also be propagated through vegetative cuttings. The cuttings should be taken from mature plants during the active growing season. The cuttings should be 10-15cm long and should have at least two nodes. The lower leaves should be removed, and the remaining leaves should be trimmed to reduce water loss. The cuttings should be planted in a well-draining potting mix and kept in a warm, humid environment. The cuttings should be misted regularly and should not be allowed to dry out. The cuttings should root in 2-3 weeks and should be transplanted into individual pots after they have established roots.
Division
Puelia dewevrei De Wild. & T.Durand can also be propagated through division. This method involves dividing the rhizomes or tubers of mature plants into smaller sections. Each section should have at least one growing point, and the cuts should be made with a sharp, sterile knife. The divided sections should be planted in a well-draining potting mix and kept in a warm, humid environment. The plants should be watered regularly but should not be allowed to sit in water. The divided sections should establish roots in 2-3 weeks and should be transplanted into individual pots after they have grown new leaves.
