To maintain the plant's health, make sure that the pH level of the soil is neutral to slightly acidic. The recommended pH level for cultivating Crassula obovata Haw. var. obovata is between 6.0 and 7.0.
Watering Needs
Overwatering can lead to root rot, which is one of the major causes of death in Crassula obovata Haw. var. obovata. It is recommended to water the plant only when the topsoil has dried out. To avoid the accumulation of water and suffocation of the roots, ensure that the container used has enough drainage holes.

Fertilization
Crassula obovata Haw. var. obovata does not require frequent fertilization like most plants since it is adapted to growing in low-nutrient soils. However, occasional fertilization will help improve the plant's overall health.
Use a water-soluble fertilizer that is low in nitrogen and high in phosphorous and potassium. Apply the fertilizer sparingly, preferably every three to four months, before the growing season begins.
Pruning
Pruning is only necessary when the plant has become overgrown or when shaping is desired. It is advisable to prune Crassula obovata Haw. var. obovata during the early spring when the plant starts to produce new shoots.
Use a sharp, clean pair of gardening shears to make a clean cut on the stem. Prune no more than a third of the plant at a time to avoid stress and shock. Take care not to cut into the woody stem since this could damage the plant.
Propagation of Crassula obovata Haw. var. obovata
Crassula obovata Haw. var. obovata is a succulent that is easy to propagate and propagate quickly. There are different methods of propagation, each with varying degrees of success. The most common methods are stem cuttings and leaf cuttings.
Propagation through Stem Cuttings
The propagation of Crassula obovata through stem cuttings is a common and straightforward method. To propagate through stem cuttings:
- Identify a healthy stem and make a clean cut, ensuring that the cutting is about 4-6 cm long.
- Leave the stem cutting to dry for a few days to form a callus, which will prevent rotting when planted in soil.
- Once the callus has formed, plant the stem cutting about 1-2 cm deep in a well-draining soil mix.
- Water the cutting and place it in a warm and bright location, away from direct sunlight.
- After a few weeks, the cutting will begin to root and produce new growth.
Propagation through Leaf Cuttings
Propagation through leaf cuttings is another popular method for Crassula obovata. To propagate through leaf cuttings:
- Select a healthy and undamaged leaf that is free from pests and diseases.
- Hold the leaf gently, and twist it off from the plant
- Set the leaf aside in a warm and dry place for about two days to allow the wound to heal.
- Once the wound has healed, plant the leaf flat onto the well-draining soil mix. Leave the soil moist but not waterlogged.
- Place the planted leaf in a warm and bright location, away from direct sunlight.
- After a few weeks, the leaf will begin to develop roots, and a tiny plantlet will emerge from the base of the leaf.
Propagation of Crassula obovata through any method is easy and rewarding. With the right care and attention, young plants can grow into mature plants that will produce beautiful blooms.
