What are the key points to note when growing Japanese aralia (Fatsia japonica)?
Temperature conditions
Japanese aralia (Fatsia japonica) prefers a cool growing environment, with an ideal temperature between 10-25°C; generally it can maintain good growth indoors at 18-20°C during the day and 10-12°C at night. Note that prolonged high temperatures can easily make its leaves thinner and larger, and they begin to droop. Japanese aralia is relatively cold-tolerant and can overwinter safely at temperatures above 7°C.
Light conditions
Japanese aralia is a semi-shade plant with strong shade tolerance, but it dislikes strong light. It is suitable for greenhouse cultivation; except in winter, shading should generally reach more than 60%, with particular attention to direct strong sunlight in summer, so shading work should be strengthened. On the other hand, if light is insufficient for a long time, the leaves will become small and thin. In winter, it needs more sunlight.
Water and fertilizer
During the growing season of Japanese aralia, that is, from April to October, apply a thin liquid fertilizer about once every 2 weeks, and stop fertilizing after October. In hot seasons, water frequently to keep the soil moist, and at the same time spray water on the leaf surfaces and surroundings to raise the nearby air humidity. After October, gradually reduce watering and control watering.
Soil requirements
It is suitable to choose fertile, loose soil with good drainage. For potting soil, you can mix 3 parts garden soil with 1 part rice husk ash, then add a little base fertilizer.
Repotting and soil turning
During cultivation, the pot should be changed once every 1-2 years, generally in March or April. When turning the soil and repotting, base fertilizer should be placed at the bottom of the pot.
How to grow Japanese aralia: cultivation methods and key points for Japanese aralia
Japanese aralia is a very popular indoor foliage plant. Do you know how to grow Japanese aralia? Today we will share the cultivation methods and key points for Japanese aralia.
Cultivation methods for Japanese aralia:
1. Soil selection. When growing Japanese aralia, choose fertile neutral or slightly acidic soil with good permeability. This is beneficial for the growth of the roots and stems of Japanese aralia, as well as the absorption of nutrients. Clay loam, fine sandy soil and saline-alkali soil are not suitable for cultivating Japanese aralia.
2. Light and temperature. Japanese aralia likes a semi-shaded environment, and during cultivation it can be placed in a bright indoor spot for a long time. If the light is too strong, the leaves tend to curl at the edges and dry at the tips, or even get scorched; if the light is insufficient, the leaves will become thinner, yellow, and lack toughness, affecting their ornamental effect. The most suitable growing temperature for Japanese aralia is 10-20°C. In winter, the cultivation temperature should not be lower than 5°C, otherwise the plant will suffer cold damage; if the temperature is too high, the plant will grow leggy, and the leaves will be thin, drooping and yellow.
3. Watering and fertilizing. Japanese aralia likes a moist environment. In daily management, the potting soil should be kept moist but not waterlogged. In winter, generally water thoroughly once every 4-7 days; in spring and autumn, water thoroughly once every 3-4 days; in summer, water thoroughly once in the morning and once in the evening. However, on rainy days, water less or not at all. During the rainy season, be careful to prevent water accumulation in the pot, otherwise it will cause root rot in Japanese aralia. You can appropriately spray the leaves of Japanese aralia to maintain its ornamental value.
During the summer growing period, it is advisable to fertilize Japanese aralia once a week. You can use granular fertilizer with equal amounts of nitrogen, phosphorus and potassium, applied after loosening the soil. For variegated Japanese aralia, apply less nitrogen fertilizer; too much nitrogen fertilizer will gradually fade the variegated patches and turn them green.
4. Pest and disease control. When growing Japanese aralia, pay attention to the prevention and control of pests and diseases, and achieve early detection and early treatment.
5. Pruning and shaping. When growing Japanese aralia, pay attention to proper shaping and pruning. In addition, you can repot before new buds sprout each spring.
6. Propagation of Japanese aralia. Japanese aralia can be propagated by sowing, cuttings or division.
Key points for growing Japanese aralia:
1. Japanese aralia grows well in an environment with high air humidity and sufficient soil moisture, so be careful that the potting soil does not lack water, otherwise it will cause a large number of leaves to fall off. If a plastic container is used for planting, pay attention to drainage.
2. Japanese aralia should be placed in a semi-shaded spot. In summer, pay attention to timely shading and do not let the scorching sun shine directly on it. In addition, poor ventilation or too dim light can also cause the leaves of Japanese aralia to fall off.
How to grow Japanese aralia: cultivation methods and key points for Japanese aralia
The Japanese aralia plant is native to southern Japan and gardens in North China and Kunming, Yunnan, China. Because the Japanese aralia plant can absorb harmful indoor gases and also greening the indoor environment, it is the best decorative plant for indoors. The Japanese aralia plant has beautiful leaf shapes and is evergreen all year round, making it a very popular indoor foliage plant. So let us learn together about how to grow Japanese aralia, and the cultivation methods and key points for Japanese aralia!
How to grow Japanese aralia: cultivation methods and key points for Japanese aralia:
1. Growth habits: It is understood that the Japanese aralia plant likes a warm and humid growing environment; at the same time, it is shade-tolerant, not drought-tolerant, and has a certain degree of cold tolerance. Planting this plant in well-drained, moist sandy loam is more conducive to the growth of the Japanese aralia plant.
2. Watering and fertilizing: After the Japanese aralia plant has grown for a period of time, growers should water it scientifically and reasonably, and must not water too much, otherwise it will cause the plant roots to rot. During the rainy season, growers should drain water in time, which is more conducive to the normal growth of the plant. The Japanese aralia plant generally enters a vigorous growth period from April to October, and a thin liquid fertilizer can be applied about once every 14 days; after October, fertilizing should be stopped in time. In the high-temperature seasons of summer and autumn, growers should water frequently, and at the same time spray water on the leaf surfaces and surrounding space to increase the air humidity around the Japanese aralia.
3. Light: The Japanese aralia plant belongs to the semi-shade plants, and growers should avoid strong sunlight. When cultivating Japanese aralia in a greenhouse, sufficient absorption for photosynthesis should be supplemented in winter; in spring, summer and autumn, shading should be more than 60%. Even a short period of direct sunlight in summer may cause sunscald on the leaves of the Japanese aralia plant. Long-term insufficient light for the Japanese aralia plant will cause the leaves to become small and thin. In April, when the Japanese aralia plant is placed outdoors for cultivation, it should be kept under a shade shed or in the shade of trees.
The above is how to grow Japanese aralia, and the cultivation methods and key points for Japanese aralia. With careful management and cultivation, the Japanese aralia plant can absorb harmful gases in the air and the external environment. At the same time, ventilation management indoors should be strengthened, which can effectively improve the ornamental value of the Japanese aralia plant.
