Watering Needs
Proper watering is crucial in maintaining healthy Crassula tetragona L. subsp. acutifolia (Lam.) Toelken.

Propagation of Crassula Tetragona Subsp. Acutifolia
The Crassula Tetragona Subsp. Acutifolia, also known as the Miniature Pine Tree, is a succulent plant that makes a great addition to rock gardens or indoor plant collections. It is a slow-growing plant, but it can reach up to 3 feet in height if grown in its natural habitat. The following are the propagation methods for Crassula Tetragona Subsp. Acutifolia.
Propagation by Stem Cuttings
One of the easiest ways to propagate Crassula Tetragona Subsp. Acutifolia is through stem cuttings. Select a healthy stem with at least two nodes. Cut the stem using a sterile knife or scissors, then let it dry for a day or two in a shaded and dry area.
After the cutting has dried, dip it into rooting hormone powder to encourage root growth. Place the cutting in a well-draining potting mix and water regularly. Within a few weeks, you should notice signs of growth.
Propagation by Division

Plant each section in a well-draining potting mix and water regularly. Keep the plant in a shaded and dry area until new growth appears.
Propagation by Leaf Cuttings
Propagation by leaf cuttings is a bit tricky but still possible. Select a healthy leaf from the plant and cut it using a sterile knife or scissors. Make sure the cutting includes the leaf's base as it will be used to create new roots.
Place the cutting in a well-draining potting mix and water regularly. New growth should appear from the base within a few weeks. Be patient as this method takes longer compared to stem cutting and division propagation method.
Overall, Crassula Tetragona Subsp. Acutifolia is a wonderful plant to propagate and grow. The above propagation methods are all effective, so choose the one that best fits your preference and start growing this amazing succulent plant.
