What are the key points to note when growing citron? An analysis of the latest key points
Citron is a plant of the genus Citrus in the family Rutaceae. Its appearance is somewhat similar to that of pomelo, but its taste is sour and it has less flesh, so it is generally not used for eating. It is usually used as medicine or as an ornamental fruit plant. It is currently grown in all major regions nationwide, so what should be noted when growing it? Let's take a look together.
1. Proper pruning
Because the branching ability of citron is relatively weak, in order to increase the width of the canopy and raise the yield, it should be pruned properly during the growing period to encourage the plant to produce more branches. It is best to combine this with tying and shaping, and retain as many branches and leaves as possible. In addition, in autumn and winter, attention should also be paid to pruning. Dense branches, leggy branches, and pest- and disease-damaged branches should be pruned off to encourage the plant to sprout early the following year, bloom and bear fruit earlier, and increase the yield.
2. Pay attention to watering
Citron prefers a warm and humid environment and is suitable for growing in high-temperature and high-humidity conditions. However, before flower bud formation, the amount and frequency of watering should be reduced to stop the branch tips from growing. By late August, watering should be stopped. After drying, the plant becomes short of water and the leaf margins curl inward. When the main buds of the plant have already swollen and turned from green to white, flower bud differentiation is complete. At this time, watering can be resumed, and some light fertilizer can be applied as a top dressing. When the soil is too dry, a little water can be sprinkled on the leaves in the morning and evening, and some water can be poured onto the root zone at noon. This can prevent the leaves from wilting. During the flowering and fruiting period, attention should be paid to the amount of watering. Both heavy watering and light watering can cause flower and fruit drop. Do not sprinkle water during the flowering period. In the evening, water can be sprinkled beside the plant to prevent dust. When the young fruit grows to the size of a soybean, the amount of watering can be appropriately increased, and phosphorus and potassium fertilizer can be added to promote the rapid expansion of the young fruit.
3. Management during the fruiting period
During the fruiting period, the temperature should not be too high, and clear and humid control should be maintained. This can improve fruit quality, and if it is grown as an ornamental potted plant, doing so can extend the fruit-viewing time. During the fruiting period, sufficient light should be maintained and no shading should be used. If light is insufficient, it will affect the photosynthesis of the leaves, reduce nutrient synthesis, and be unfavorable to the growth and development of the fruit.
