SummaryPotting soil: For red-leaf Rohdea, you can use leaf mold, garden soil and river sand mixed with a small amount of decomposed base fertilizer in a certain ratio to make the growing medium, and repot once every spring. Temperature: The optimal growing temperature is 15-18°C, and it must not go below 5°C. Light: It prefers a semi-shaded environment and should not be exposed to direct sunlight, so provide shade. Shaping: Promptly prune yellow leaves, damaged leaves and some old leaves at the lower part of the plant. Water and fertilizer: Apply liquid fertilizer once every 10-15 days, water 1-2 times a day in summer, and water less in winter.

I. Growing Methods for Red-Leaf Rohdea

1. Potting soil

For potted red-leaf Rohdea, you can use 2 parts leaf mold, 1 part garden soil and 1 part river sand, mixed with a small amount of decomposed base fertilizer to make the growing medium. During the growing season, be sure to water more to keep the potting soil moist; it is better to keep it wet than dry. You can also spray water on the leaves. In autumn, water should be controlled, alternating between dry and moist. In winter, keep the potting soil dry. Repot once every spring.

2. Temperature

The suitable growing temperature for red-leaf Rohdea is 15-18°C. In winter it enters dormancy, so it should be placed in a sunny spot, and the temperature should be kept above 10°C; the lowest temperature must not go below 5°C. In the Yangtze River basin, it can overwinter outdoors; the leaves will suffer frost damage, but new leaves can sprout again the following year.

3. Light

Red-leaf Rohdea likes to grow in a semi-shaded environment, and in summer it must be protected from direct sunlight. When grown in a greenhouse, shade of more than 60% should be provided except in winter, and 40% shade in winter, because too strong light can easily scorch it, while too weak light is also unfavorable for flowering and fruiting.

4. Shaping

According to the plant's growth, promptly prune yellow leaves, damaged leaves and some old leaves at the lower part of the plant, which helps maintain a good shape and thus improves its ornamental value. For home growing, you can wipe the leaves with a soft cloth dipped in beer, which not only removes dust but also adds nutrients to the leaves, making them cleaner and more glossy green.

5. Water and fertilizer

During the growing season, apply liquid fertilizer once every 10-15 days. In summer, increase ventilation, prevent heat and lower the temperature, ensure sufficient water, and keep the potting soil moist. In summer, water 1-2 times a day; in winter, water sparingly and do not fertilize.

II. Propagation Methods

1. Sowing method: Generally, sowing can be done separately around March to April. Sow in a flowerpot filled with growing medium, then water to keep the soil moist, place in a shaded spot, and under a temperature of 25-30°C, germination will occur in about 25 days.

2. Division method: Because its underground stem has strong sprouting ability, in spring and autumn you can use a knife to cut off the newly sprouted shoots at the rhizome together with some lateral roots, then apply plant ash to the wound, transplant into a pot, water lightly, place in a shaded spot, and after 1-2 days water thoroughly. You can also turn the whole plant out of the pot and, depending on the size of the plant, use a knife to divide it into several parts. After the wounds dry, apply plant ash, and the potting method is the same as above.

3. Cuttage method: In spring, from April to May, cut off the small plantlets growing from the base of the plant. After the wounds dry, apply plant ash, then insert them into plain sand soil. Be sure to provide shade and keep them moist. They will root in about 30 days and can then be potted.

III. Notes on Growing

1. Because it is a fleshy-root plant, do not overwater it; waterlogging can easily cause damage from excess moisture and, in severe cases, root rot.

2. If in winter the leaf tips turn yellow and scorched, or even the whole plant withers, the cause is that the roots cannot absorb water, which affects its growth.

3. For indoor growing, keep it warm, humid and in a semi-shaded environment. During the summer growing season, it should be placed in a shaded spot to prevent strong direct light, otherwise the leaf tips may dry out and the edges scorch, thus affecting the ornamental effect.
