Propagation of Malaxis stolzii (Schltr.) Summerh.

There are a few ways to propagate Malaxis stolzii, including seed propagation and vegetative propagation.

Seed Propagation

The propagation of Malaxis stolzii can be done by seed, which is usually available easily. The seeds are small and can be sown as soon as they are mature.

First, soak the seeds in water for up to 24 hours. Create a propagation mixture with peat and coarse sand, with a 1:1 ratio. Mix and moisten the propagating medium, and fill it into small pots or flats. Sow seeds onto the medium, evenly spaced, and cover them with a thin layer of sand. Place the containers in a warm site of about 20-25°C in the light shade. Keep them moist and expect germination to begin within three months.

Vegetative Propagation

Another method of propagation is vegetative propagation. This involves using small sections of the plant to create a new plant.

To propagate through vegetative means, first, examine the plant and identify where the developing shoots are, and make sure that they are strong and healthy. Carefully remove these shoots, taking care not to damage the other parts of the plant. Dip the cut areas in hormone rooting powder. Prepare a soil mixture of perlite and peat moss in a 1:1 ratio. Plant the shoots in the soil mixture, taking care to keep similar spacing to the original plant. Then, water the plants thoroughly and place them in a bright, humid area. They will root and develop into new plants in a few months.
