How to Grow Rohdea japonica? Detailed Guide to Cultivation Methods and Precautions
Although the name Rohdea japonica sounds like it has very strong vitality, if cared for improperly, Rohdea japonica may also lose its green. If you want your Rohdea japonica to truly stay evergreen for ten thousand years, then you must first understand the cultivation methods and precautions for growing Rohdea japonica. Next, follow the editor to learn about it together!
1. Preparation of potting soil: For potted Rohdea japonica, use 2 parts leaf mold, 1 part garden soil, 1 part river sand plus a small amount of decomposed base fertilizer as the growing medium. During the growing season of Rohdea japonica, to keep the potting soil moist, water more frequently, preferring wet over dry, and at the same time supplement with spraying water on the leaves. In autumn, control water and alternate between dry and wet; in winter, pay attention to keeping the potting soil dry. During the growing period, fertilize generally once a month. Usually prevent direct sunlight and provide shade. Repot once every spring. The wintering temperature in winter must not be lower than 10°C.
2. Light and temperature: Rohdea japonica likes a semi-shaded environment and fears direct sun exposure in summer. For greenhouse cultivation, shade should be 60% or more in spring, summer and autumn, and 40% in winter. Too strong light easily causes sunburn, while too weak light makes it difficult to bloom and bear fruit. The suitable growth temperature is 15-18°C. In winter, when dormant, move it into a greenhouse, place it in a sunny spot, and keep the temperature above 10°C; the lowest temperature must not be below 5°C. In the Yangtze River basin, it can overwinter outdoors. Although the leaves may suffer frost damage, new leaves can still sprout again the following year.
3. Watering and fertilizing: During the growing season, apply liquid fertilizer once every 10-15 days. In summer, strengthen ventilation, prevent heat and lower temperature, and provide sufficient water, often keeping the potting soil moist and the surrounding air humid. In summer, water 1-2 times a day. In winter, reduce watering and stop fertilizing.
Precautions for Growing Rohdea japonica1. Soil: It is advisable to use sandy loam rich in humus as the growing medium. Keeping the soil pH at 6~6.5 is more conducive to fully absorbing nutrients.
2. Rohdea japonica likes a semi-shaded, warm and ventilated environment, so the temperature generally must be kept above 10°C. Except that Aspidistra elatior is slightly more cold-tolerant, other varieties all need to be kept at 10°C~32°C. In winter, it can be maintained in full sun, and in summer, direct light must be strictly avoided. In winter, when indoor ventilation is poor, scale insect damage often occurs. Once discovered, immediately brush them off with a small brush or spray No. 20 petroleum emulsion diluted 100-150 times with water to kill them.
3. Rohdea japonica likes moisture and is not drought-tolerant, but it is best to water only when the surface of the potting soil looks dry. Excessive wetness and waterlogging will rot the root system (the root system is generally fleshy), while in drought it may wilt due to high transpiration.
4. Fertilizing generally starts again when the spring temperature rises to 18°C. No fertilizing is needed during high summer temperatures or low winter temperatures.
5. If you want Rohdea japonica to grow well with green leaves, promptly clean and wipe off the dust on the leaves. In addition, if leaves turn yellow or scorch, prune them promptly to avoid unnecessary consumption of excessive nutrients.
The above is the relevant introduction to the cultivation methods and precautions for growing Rohdea japonica. When growing Rohdea japonica, everyone must pay attention: no matter how strong its vitality is, Rohdea japonica also has fatal weaknesses. When growing Rohdea japonica indoors, be sure to maintain a warm, humid and semi-shaded environment, and do not let Rohdea japonica be directly exposed to strong light.
