Light Requirements
Crassula pubescens Thunb. typically thrives in bright, indirect light. Direct sunlight for extended periods can cause damage to the leaves. Therefore, it is advisable to place the plant near a window that receives bright light but is shaded from intense sunlight. A north or east-facing window would be a suitable spot for the plant.
Temperature Requirements
Crassula pubescens Thunb. is native to South Africa, where temperatures are usually warm. Therefore, the plant prefers warm temperatures ranging from 60-75°F (15-24°C). During winter, the temperature could drop to 50°F (10°C) as the plant becomes dormant. However, it is advisable to keep it away from drafty areas that could cause temperature fluctuations, which can lead to stress and damage the plant.
Soil Requirements
The plant prefers well-draining soil that retains moisture but does not get waterlogged. You can purchase a cactus/succulent mix or create a mixture of 1 part perlite, 2 parts sand, and 2 parts peat moss to provide sufficient drainage. Crassula pubescens Thunb. grows best in soil with a pH ranging from 6.0 to 7.0.
Cultivation methods
Crassula Pubescens Thunb. is a succulent plant that requires well-draining soil to prevent root rot. It is best grown in bright, indirect sunlight and in temperatures between 60-80°F. The plant can tolerate low humidity levels, making it ideal for indoor growth. It is recommended to grow the plant in a container with drainage holes to avoid water building up at the roots.
Watering needs
The Crassula Pubescens Thunb. plant is drought tolerant and requires infrequent watering. The soil should be allowed to dry out completely between watering to prevent waterlogging. Overwatering can lead to root rot, which can be fatal for the plant. It is best to water the plant deeply once every two weeks during the growing season and once a month during the dormant season.
Fertilization
During the growing season, Crassula Pubescens Thunb. requires regular fertilization to encourage healthy growth. The plant can be fertilized using a balanced liquid fertilizer diluted to half strength. Fertilizer should be applied once a month, following the manufacturer's instructions. It is essential to avoid over-fertilizing the plant, as this can lead to damage or death.
Pruning
Crassula Pubescens Thunb. requires minimal pruning to encourage branching and maintain its shape. The plant produces flowers on the stems, so it is best to avoid cutting back the plant during the flowering season. Pruning can be done during the growing season, preferably early spring, by cutting back the stems to promote bushy growth and remove any diseased or damaged parts.
Propagation methods for Crassula pubescens Thunb.
Crassula pubescens Thunb. is a popular succulent plant that is easy to propagate. There are several methods to propagate this plant, including by seed, stem cuttings, and leaf cuttings.
Seed propagation
Propagation by seed is a slow process, but it is the most natural way to reproduce Crassula pubescens Thunb. To propagate by seed, collect the seeds from the plant when the seed pods open and allow the seeds to dry for a few days. Sow the seeds in a well-draining potting mix and keep the soil moist. The seeds will germinate within a few weeks to a month, and once they have established, they can be transplanted.
Stem cutting propagation
Propagation by stem cuttings is a popular method for Crassula pubescens Thunb. To propagate by stem cutting, take a cutting from the stem of the plant and let it dry for a few days. Once the cut end has calloused over, place the cutting in well-draining potting mix and water it sparingly. Within a few weeks to a month, roots will start to develop, and new growth will appear.
Leaf cutting propagation
Propagation by leaf cuttings is another common method for Crassula pubescens Thunb. To propagate by leaf cutting, remove a leaf from the plant and let it dry for a few days. Once the leaf has calloused over, place it on well-draining potting mix and water sparingly. Within a few weeks, new roots will start to form, and a new plant will develop from the base of the leaf.
Overall, Crassula pubescens Thunb. is an easy plant to propagate, and by using any of the above methods, you can quickly grow new plants to share with friends and family or to expand your own collection.
