Propagation of Buchholzia macrothyrsa Gilg & Gilg-Ben.
Buchholzia macrothyrsa Gilg & Gilg-Ben. can be propagated using seeds or cuttings. However, propagation via seeds is considered as the most efficient method for the plant.
Propagation through Seeds
The seeds of Buchholzia macrothyrsa Gilg & Gilg-Ben. are usually collected when they are ripe and dry. This is often in the months of July to August. To propagate the plant via seeds, the first step is to remove the pods and allow them to dry out completely in the sun.
After this, the seeds are extracted from the pods and cleaned. To increase the germination rate, the seeds can be soaked in lukewarm water for 24 hours before planting. This would soften the hard seed coat and allow the water to penetrate the seeds.
The seeds should be sowed at a depth of 1-2 cm in a well-draining soil mix. The soil must be kept moist and warm. Germination usually occurs within 7 to 14 days.
Propagation through Cuttings
Cuttings can be taken from Buchholzia macrothyrsa Gilg & Gilg-Ben. during the summer months. The cuttings should be taken from the tips of healthy and matured shoots, and it should be at least 8-10 cm long. The lower leaves of the cutting should be removed, leaving 2-3 leaves at the top.
The cuttings should be dipped in a rooting hormone and planted in a well-draining soil mix. The soil should be kept moist, and the cutting should be kept in a warm and humid environment. The rooting of the cutting usually takes around 4 to 5 weeks.
