Crassula ovata 'Sunset' is a variety of the more commonly known Jade Plant. This variety is particularly striking due to its vibrant golden-yellow and red-tinged leaves when exposed to ample sunlight. It is a slow-growing succulent that can reach up to 3 feet in height when mature, but it can take many years to achieve this size. Here's a detailed care guide for Crassula ovata 'Sunset':

Light:

• Indoor: It thrives in bright, indirect light. A south or west-facing window is ideal. If the plant gets ample light, the yellow and red colors of the leaves will be more pronounced.
• Outdoor: Prefers partial sunlight. Full afternoon sun might be too intense and could lead to leaf scorching.

Water:

• Like most succulents, 'Sunset' doesn't like to be overwatered. Allow the top inch or so of the soil to dry out between waterings. In the growing season, you might water once every 2-3 weeks, but always check the soil first.

Soil:

• A well-draining succulent mix is essential. Consider a mix of potting soil, coarse sand, and perlite or pumice.

Temperature:

• This plant prefers temperatures between 60°F to 75°F (15°C to 24°C). It can tolerate slightly cooler temperatures at night, but protect it from frost.

Fertilizer:

• During the growing season (spring and summer), feed the plant once every 4-6 weeks with a diluted balanced fertilizer.

Repotting:

• Repot when the plant becomes root-bound or when it outgrows its pot. Make sure any new pot has sufficient drainage holes.

Pruning:

• Prune to maintain its shape or to encourage bushier growth. You can also prune to remove damaged leaves or stems.

Pests and Diseases:

• Crassula ovata varieties can be susceptible to mealybugs, spider mites, and occasionally aphids. Use insecticidal soap or neem oil as a treatment if you notice pests.
• Overwatering can lead to root rot. Always ensure your pot drains well and that you're not letting the plant sit in standing water.

Propagation:

• 'Sunset' can be propagated from leaves or stem cuttings. For best results, let the cutting dry for a few days, allowing it to form a callous over the cut end, then plant in a well-draining mix.

Additional Tips:

• If you want to encourage the bright yellow and red coloration, provide the plant with plenty of light. However, sudden exposure to intense sunlight can scorch the leaves, so if you're moving it to a brighter location, do it gradually.
• The leaves can be easily damaged by touching or bumping. Handle with care during repotting or moving.

By adhering to this care guide, your Crassula ovata 'Sunset' will grow healthily and showcase its beautiful coloration, making it a standout in any succulent collection.
