What should be noted when planting citron

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. At present, it is planted in all major regions across the country, so what should be noted when planting it? Let's take a look together.

1. Proper pruning

Because citron has weak branching ability, in order to increase the width of the crown and raise the yield, it should be properly pruned during the growth 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, removing dense branches, leggy branches, and pest- and disease-affected branches, so as to encourage the plant to sprout early the next 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, but 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 edges 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 should be applied as a top dressing. When the soil is too dry, some water can be sprinkled on the leaves in the morning and evening, and some water can be poured on the roots at noon, which can prevent leaf wilting. During the flowering and fruiting period, pay attention 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 should be added to promote 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. At this time, the quality of the fruit can be improved, and if it is used 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 detrimental to the growth and development of the fruit.
