Detailed Guide to Growing and Caring for Rohdea japonica
Rohdea japonica is a perennial evergreen plant in the Asparagaceae family, and it is fairly widely distributed in China. Rohdea japonica has very high ornamental value, and as a potted plant it is very popular in offices, homes and other places in China. Rohdea japonica also has effects such as clearing heat and detoxifying, and dispersing blood stasis and relieving pain. So how should Rohdea japonica be grown? Below, the editor brings you the growing methods and precautions for Rohdea japonica. Let's take a look!
1. Soil selection
Rohdea japonica is not very strict about its soil requirements, but when planting, hard clay or alkaline soil should not be chosen. Sandy soil that is permeable, drains and irrigates well, and is rich in organic matter is best. The soil pH should be kept at around 6, so that soil nutrients can be effectively used. If growing it in pots, then attention must be paid to changing the soil and repotting every year. When repotting, remove rotten leaves and roots, and use slightly acidic soil as the growing medium. Although ordinary soil can grow it, soil that is rich in nutrients and loose is best for the growth of Rohdea japonica.
2. Scientific fertilisation
During the growth period of Rohdea japonica, we should do a good job of fertilising; generally, a decomposed liquid fertiliser should be applied once every 3 weeks or so. If applied together with New High Lipid Film, it can also improve fertiliser efficiency and enhance the appearance of the flowers and the number of blooms. In early summer, Rohdea japonica grows faster, and at this time it can be fertilised once every 10 days or so. A small amount of ammonium sulfate can be added to the fertiliser, which can improve the glossiness of the leaves. June is the peak flowering period of Rohdea japonica, and at this time it should be fertilised once every half month to promote flower bud differentiation and increase the number of flowers and fruits. After entering winter, fertilisation should be stopped.
3. Reasonable watering
The roots of Rohdea japonica are fleshy roots, and a warm and humid environment should be maintained when growing it. So we should water frequently to keep the soil moist, but the amount of water should not be too much. If water accumulates, then Rohdea japonica will suffer from waterlogging, and root rot is likely to occur. Every morning and evening, water can be sprayed on the ground around the flower pot to increase humidity. When watering, do not flood-irrigate, especially during the flowering period, when protection from rain should be done well. And to improve the ornamental value of Rohdea japonica, the leaves should be washed once a week with warm water to prevent too much dust on the leaves from reducing the ornamental value.
4. Precautions
Rohdea japonica does not need much light and likes to grow in a semi-shaded environment, and must not be exposed to direct sunlight. So in summer we should pay attention to doing a good job of shading; apart from winter, the shade level in the other three seasons should be kept above 60%. In winter it can be appropriately reduced by 20%, and the light should be kept moderate; too much or too little has a very great impact on the growth of Rohdea japonica. Finally, we should also pay attention to doing a good job of pruning, promptly cutting off yellow leaves, damaged leaves, old leaves and so on. This improves the overall ornamental value of Rohdea japonica.
The above is a brief introduction to the growing methods and precautions for Rohdea japonica. Growing Rohdea japonica is relatively simple, but attention should be paid to controlling light, temperature and so on well to ensure the normal growth of Rohdea japonica. That is all for today's introduction. This article is for reference only, and I hope it can help everyone!
