Propagation of Tetramolopium humile (Gray) Hbd. var. skottsbergii Sherff
Tetramolopium humile (Gray) Hbd. var. skottsbergii Sherff, commonly known as Skottsberg's tetramolopium, is a plant species native to one of the smallest and most isolated archipelagos in the world, the Juan Fernandez Islands, Chile. This plant is part of the Asteraceae family, and it has become very popular among succulent lovers and collectors. If you want to propagate your Skottsberg's tetramolopium, you will need to follow some specific techniques.
Propagation Methods
The most common way to propagate tetramolopium humile is through stem cuttings, which is the easiest and quickest method for propagation. Select a healthy stem that has grown at least four leaves, and use a sharp, sterilized blade to cut the stem. Remove the leaves from the bottom third of the cutting, and then insert the stem into a well-draining soil mixture. Water the soil well, and, to increase humidity, cover the pot with a clear plastic bag or plastic wrap, securing it with a rubber band.
Alternatively, tetramolopium humile can also be propagated by seeds. Collect ripe seeds from the plant and sow them in well-draining soil. Cover the seeds with a thin layer of soil mix, keeping the soil moist throughout the germination period. It may take between 15 and 30 days for the seeds to germinate.
Keep the soil moist and the seedlings in a shaded area until they grow to about two to four true leaves. Gradually acclimate the plants to brighter light and lower humidity, but avoid direct sunlight. You can transplant the plant into a larger pot once it has outgrown its current container.
Disease Management for Tetramolopium humile (Gray) Hbd. var. skottsbergii Sherff
