Propagation of Aletes macdougalii Coult. & Rose ssp. macdougalii
Aletes macdougalii Coult. & Rose ssp. macdougalii can be propagated through various methods. Below are some of the most commonly used propagation methods:
Seed Propagation
Seed propagation is one of the most popular propagation methods for Aletes macdougalii Coult. & Rose ssp. macdougalii. The seeds of the plant can be sown in the nursery beds or directly in the field during the rainy season. The seeds may take few weeks to germinate and grow into saplings.
Cuttings Propagation
Cuttings is another method of propagating Aletes macdougalii Coult. & Rose ssp. macdougalii. Cuttings should be taken from the healthy and mature plants. The cuttings should be about 5-7 inches long.

The cuttings will take about 4-6 weeks to establish roots.
Division Propagation
Division propagation method involves separating the well-established plant into two or more parts. This method is best suited to propagate older, larger plants. The parent plant should be uprooted and carefully separated into two or more parts. Each part should have enough roots and shoots to survive on its own. The separated plants should be immediately planted in well-prepared soil.
Layering Propagation
Layering propagation is a method where new plants are obtained through the aerial branches or stems of the parent plant. The selected branch should be bent towards the soil and a small slit should be made at the bottom. This slit should then be covered with soil and kept moist. Within a few weeks, new roots will develop and can be separated from the parent plant.
