Light Requirements
Crassula rubescens var. laxa requires bright, indirect light to thrive. It can tolerate some direct sunlight, but too much can burn the leaves. Ideally, the plant should receive at least six hours of bright, indirect light per day. Place it near a south-facing window or use grow lights if necessary.
Temperature Requirements
This plant prefers moderate temperatures ranging from 60-75°F (15-24°C). It can tolerate temperatures as low as 50°F (10°C) but should be kept away from frost and extreme heat.
Soil Requirements
Crassula rubescens var. laxa grows best in well-draining, sandy soil. A mixture of cactus soil or potting soil with perlite or sand works well. The soil should be slightly acidic with a pH between 6.0-7.0.
Cultivation Methods
Crassula rubescens Schönland & Baker f. var. laxa Schönland is a succulent plant that is not very demanding in terms of its cultivation. It requires well-draining soil that is enriched with organic matter, such as compost. It is a hardy plant that can tolerate high temperatures and low humidity, making it a perfect indoor plant.
The plant can be propagated through stem cuttings that are allowed to callous and plant in a well-draining soil mix. It is crucial to avoid planting it in a pot that is too big for the plant.
Watering Needs
Watering needs for Crassula rubescens Schönland & Baker f. var. laxa Schönland are low, making it an ideal plant for forgetful gardeners. It thrives in dry soil, and overwatering can cause root rot. Watering should be done when the soil is completely dry, ideally in the morning hours when the sun is not too hot.
During the winter season, watering should be reduced to once every two or three weeks. When watering, it is best to avoid getting water on the leaves to prevent leaf damage.
Fertilization
Crassula rubescens Schönland & Baker f. var. laxa Schönland does not require a lot of fertilization. Fertilization should be done during the growing season in the spring and summer months using a low-nitrogen fertilizer that is high in phosphorus and potassium.
Fertilization should be done every four to six weeks, and it is essential to avoid over-fertilizing as it can cause burnt roots.
Pruning
Crassula rubescens Schönland & Baker f. var. laxa Schönland does not require much pruning. However, dead leaves and stems should be trimmed off to prevent the plant from wasting energy on them.
To encourage the plant's branching, it can be pinched at the tips of its shoots. When pruning, it is essential to use sanitized scissors or shears to prevent the spread of diseases.
Propagation methods for Crassula rubescens Schönland & Baker f. var. laxa Schönland
There are several ways to propagate Crassula rubescens Schönland & Baker f. var. laxa Schönland, including:
Leaf cuttings
This is one of the easiest ways to propagate Crassula rubescens Schönland & Baker f. var. laxa Schönland. Take a healthy leaf from the parent plant and allow it to dry for a few days. Once the cut end has healed, simply place it on top of the soil and mist it regularly until roots and a new plant start to form.
Stem cuttings
Another way to propagate Crassula rubescens Schönland & Baker f. var. laxa Schönland is through stem cuttings. Select a stem that's at least 3 inches long and cut it just above a leaf node. Remove the leaves from the bottom two inches of the stem and place it in a pot with well-draining soil. Water it well and keep the soil moist until roots and new growth appear.
Division
Crassula rubescens Schönland & Baker f. var. laxa Schönland can also be propagated through division. This method involves dividing the parent plant into sections and planting each one as an individual plant. Make sure each division has several healthy leaves and roots. Repot each section in fresh soil and water it well.
Seed propagation
Although it's possible to propagate Crassula rubescens Schönland & Baker f. var. laxa Schönland from seed, it's not common. Collect the seeds from the parent plant and sow them in well-draining soil. Keep the soil moist and wait for the seeds to germinate. It's generally easier to propagate the plant through one of the other methods mentioned above.
Disease management
Crassula rubescens Schönland & Baker f. var. laxa Schönland is a relatively hardy plant that is not prone to many diseases. However, it can still be affected by leaf spot disease, which is caused by a fungus called Cercospora. This disease can cause yellow or brown spots on the leaves, and in severe cases, the leaves may drop prematurely. To manage leaf spot on Crassula rubescens, ensure that the plant is not overwatered, and avoid overhead watering. Fungicides can also be used to control the spread of the disease.
Another disease that can affect Crassula rubescens is root rot. This disease is caused by fungi such as Phytophthora and Pythium and can lead to wilting, yellowing, and eventual death of the plant. To prevent root rot, ensure that the potting soil is allowed to dry out completely between waterings, and avoid overwatering. Fungicides can also be used to prevent the spread of the disease.
Pest management
Crassula rubescens Schönland & Baker f. var. laxa Schönland is also susceptible to attack by pests such as spider mites and mealybugs. Spider mites are tiny pests that usually appear on the underside of leaves, and they can cause yellowing and wilting of the leaves. To manage spider mites on Crassula rubescens, spray the plant with a stream of water to dislodge the pests, and then apply insecticidal soap or neem oil to kill the remaining mites.
Mealybugs are another pest that can attack Crassula rubescens, and they are usually found on the stems and undersides of leaves. Mealybugs feed on plant sap and can cause stunted growth, yellowing, and wilting. To manage mealybugs on this plant, prune off the infected parts, and then apply insecticidal soap or neem oil to kill the remaining pests.
