Watering needs
Crassula decumbens Thunb. var. decumbens requires moderate watering during the growing season, which is typically in the spring and summer. It's essential to allow the soil to dry out to a depth of at least an inch before watering again. The plant can tolerate drought conditions, so it's better to under-water than to over-water.
Over-watering can lead to root rot and other diseases that can harm the plant. During the winter months, reduce the amount of watering and let the soil dry out completely before adding more water.
Fertilization

Pruning
Pruning is not mandatory when it comes to Crassula decumbens Thunb. var. decumbens. However, trimming the plant annually can encourage full growth and strong stems. When pruning, use sterilized pruning tools to avoid transmitting diseases. Make clean, sharp cuts, and remove any dead leaves or stems while allowing enough healthy foliage to remain.
Propagation of Crassula decumbens Thunb. var. decumbens
There are two primary methods of propagating Crassula decumbens Thunb. var. decumbens: through stem cuttings and through seed propagation.
Propagation by Stem Cutting
Propagating Crassula decumbens Thunb. var. decumbens through stem cuttings is a common and reliable method. Cuttings should be taken in the spring when the plant is actively growing. Look for healthy stems with at least two pairs of leaves. Using a sharp, sterile knife or pair of scissors, make a clean cut just below a leaf node. Remove any leaves from the bottom half of the cutting.
Dip the cut end of the stem in rooting hormone, then gently insert it into a well-draining potting mix. Water the cutting and cover it with a plastic bag to help maintain humidity. Keep the potting mix moist, but not waterlogged. Roots should begin to form in two to four weeks.
Once roots have formed, remove the plastic bag and gradually acclimate the new plant to normal growing conditions. Transplant it to a larger container as needed.
Propagation by Seed
Propagation of Crassula decumbens Thunb. var. decumbens from seed is another option. Seeds can be sown in the spring or summer in a well-draining potting mix. Lightly cover the seeds with additional potting mix, then water gently.
Seeds should be kept warm and moist until germination occurs, which can take up to two weeks. Once seedlings have emerged, provide bright, indirect light and keep the potting mix consistently moist.
Seedlings can be transplanted to larger containers as they grow, and should be gradually acclimated to normal growing conditions. It is important to note that plants grown from seed may not display the same characteristics as their parent plant.
