What are the planting methods and precautions for Crassula capitella 'Campfire'?

Crassula capitella 'Campfire', also known as autumn fire lotus, is a perennial herbaceous plant in the Crassulaceae family and the genus Crassula. Its stems are prostrate or upright. The plant grows in clumps, with fleshy leaves arranged in opposite pairs; under normal growth conditions the leaves are closely packed, giving the whole plant a four-angled appearance. It likes a growing environment with plenty of sunlight and relatively dry conditions. In a sunny environment the leaves range from light green to bright red.

Growth habits of Crassula capitella 'Campfire'

Crassula capitella 'Campfire' is native to South Africa and can now be cultivated in many parts of the world. It likes a cool, dry and sunny environment, is tolerant of drought, afraid of waterlogging, and has a certain degree of cold resistance. In semi-shade or shade the plant can still grow, but the leaves stay green and it is hard to bring out the variety's characteristics. It likes a cool, dry and sunny environment and well-drained sandy soil.

Propagation methods of Crassula capitella 'Campfire'

Propagation of Crassula capitella 'Campfire' generally includes three methods: cuttings, division and sowing, with cuttings being the main method. Cuttings are further divided into stem cuttings and leaf cuttings. For stem cuttings, use a stem of Crassula capitella 'Campfire' and bury about the lower 2 cm in soil, keeping the soil moderately moist; roots will form within a week. For leaf cuttings, remove a leaf with the petiole as intact as possible, lay it flat on the surface of loose potting soil, and keep the soil moderately moist; within one to two weeks roots will form from the petiole, then new buds will grow and gradually develop into a new plant. The advantage of stem cuttings is that they grow into new plants more quickly, while the advantage of leaf cuttings is a high propagation rate, since each leaf can produce a new plant.

How to grow Crassula capitella 'Campfire'

1. Light: the more sufficient the light and the greater the temperature difference between day and night, the more vivid the leaf color. When temperatures allow, it is best to place it outdoors for care to ensure sufficient light. When light is insufficient or the soil is too moist, it becomes leggy, the whole plant turns light green or dark green, the leaves become sparse and the internodes elongate, growth accelerates upward, the ornamental value is seriously affected, and the plant may even die because its photosynthesis is impaired.

2. Water: Crassula capitella 'Campfire' rots easily in an overly damp environment, so never water too much. To avoid water accumulating at the roots, it is best to choose a pot with drainage holes at the bottom; beginners can use a red clay pot with good breathability. Usually water about once every 10 days, watering thoroughly each time, and adjust the watering frequency up or down according to climate differences in different regions and seasons.

3. Soil: Crassula capitella 'Campfire' should be grown in well-drained, breathable sandy soil to facilitate the removal of excess water and the growth of the plant's roots. A mix of leaf mold, sandy soil and garden soil at 1/3 each can be used. Repot once every 1 to 2 years in spring, and dead old roots can be trimmed off.

4. Temperature: below 5°C, Crassula capitella 'Campfire' stops growing or suffers mild frostbite; at 0°C and below, the water in the leaves freezes and the cells die. When temperatures in winter and summer are too high (above 35°C) or too low (below 5°C), the plant stops growing; at this time reduce or stop watering temporarily, and resume the watering frequency once temperatures are suitable. In summer heat, pay attention to ventilation and prevent prolonged exposure to avoid sunburn.

5. Pruning: usually remove dried old leaves from Crassula capitella 'Campfire' promptly to prevent them from piling up and causing bacteria to breed. When the plant becomes leggy or grows too tall, you can trim the top branches and leaves to shape it and control its height, so as to maintain a graceful form. The cut top portion can, after the wound dries, be inserted into slightly moist sandy potting soil to take root and become a new plant. The stem and branches at the bottom can sprout more side buds.

6. Fertilizer: Crassula capitella 'Campfire' should not be fertilized too much, especially with nitrogen fertilizer, otherwise the plant will become leggy and the leaves will not turn red. Apply a dilute fertilizer mainly of phosphorus and potassium once a month.

How to make Crassula capitella 'Campfire' turn red

1. Crassula capitella 'Campfire' turns very red only under the combined effect of winter dryness + cold + strong sun.

2. During the growing season Crassula capitella 'Campfire' turns green and grows rampantly; you can cut stems and keep taking cuttings, and within half a year it will become a big cluster. If you do not want to take cuttings, you can cut some off; after pruning the plant's form will be full and beautiful.

3. Once Crassula capitella 'Campfire' has a well-developed root system it becomes sturdy, and it has already stored a large amount of water in its body; then gradually cut back on watering, giving a little less each time until watering is stopped entirely, and with strong sun exposure it will turn red.

4. Crassula capitella 'Campfire' is a horticultural variety that likes a warm, dry and sunny environment; in semi-shade or shade the plant can still grow, but the leaf color will not turn red.

5. Normally do not give Crassula capitella 'Campfire' too much water or fertilizer, and especially not too much nitrogen fertilizer, otherwise the plant will become leggy and the leaves will not turn red. Wait until the potting soil is completely dry before watering, and apply a dilute fertilizer mainly of phosphorus and potassium once a month.
