Water thoroughly when the top 2-3 cm of soil feels dry. Avoid letting the plant sit in waterlogged soil, which can lead to root rot. Reduce watering frequency during winter months when the plant's growth slows down.

Key traits and growing stats from plant data
Watering, pruning, propagation, and repotting details from plant data
Water thoroughly when the top 2-3 cm of soil feels dry. Avoid letting the plant sit in waterlogged soil, which can lead to root rot. Reduce watering frequency during winter months when the plant's growth slows down.
Prune to maintain shape, remove yellow or dead leaves, and encourage bushier growth. Use clean, sharp pruning shears to make cuts just above a node.
Pruning can be done at any time of year, but is most effective in spring.
Easily propagated by stem cuttings. Take cuttings of 10-15 cm with at least two nodes, remove lower leaves, and plant in moist potting mix or place in water until roots form. Roots typically develop within a few weeks.
Repot every 2-3 years or when the plant becomes root-bound. Choose a pot that is slightly larger than the current one. Use a well-draining potting mix.
Repotting is best done in spring before the active growing season begins.
