How to Grow Wendan Pomelo? Key Points on Water and Fertilizer Management and Harvest Timing

When people think of citrus, many think of the autumn and winter market. In fact, within the citrus family, Wendan pomelo is often the variety that "takes the lead," with harvest beginning in late summer and early autumn, capturing the market early. Wendan pomelo has sweet, refreshing flesh and a rich aroma, and it enjoys a stable market reputation in many production areas. To grow Wendan well, there are actually quite a few details to manage, and the following aspects are especially key.

Water and Fertilizer Management: Strong Trees Are the Foundation of High Yield

Wendan pomelo trees are vigorous and bear heavy crops, so their water and fertilizer needs are higher than those of ordinary mandarin-type citrus. For fertilization, it is advisable to follow the approach of "replenishing nutrients after harvest, applying spring fertilizer to promote new shoots, and emphasizing potassium during the fruit-swelling stage": promptly supplement organic fertilizer after harvest to help the tree recover; apply quick-acting fertilizer before spring budbreak to promote spring shoot growth; and during the fruit expansion stage, increase potassium fertilizer, combined with foliar feeding, which can noticeably improve flesh quality. As for water, the fruit expansion stage requires more water, so irrigate promptly during drought; appropriately restrict water before harvest, which helps sugar accumulation and also makes the fruit more storability-friendly for transport. Because soil conditions and climate vary from place to place, it is advisable to refer to local agricultural extension department guidance for specific fertilizer amounts and timing.

Pruning and Fruit Thinning: The Key to Fruit Size and Quality

Wendan mainly flowers and sets fruit on bearing mother branches, and the pruning principle is "ventilation and light penetration, remove dense growth and keep sparse growth." After harvest, prune out diseased and pest-damaged branches, crossing branches, and overly dense branches so that even the inner canopy can receive light. After fruit set, fruit thinning should also be done promptly, removing deformed fruit, small fruit, and overly crowded fruit so that nutrients are concentrated in the fruit that remains. Many beginners are reluctant to thin, resulting in smaller fruit and uneven quality, which in turn fails to fetch a good price. On this point, you must be willing to be decisive.

Pest and Disease Control: Prevention Matters More Than Cure

Common pests and diseases of Wendan include citrus leafminer, red spider mite, scale insects, as well as scab and anthracnose. In control, insist on prevention first: do a good job of orchard cleanup in winter, and collect pruned diseased branches and fallen leaves for centralized disposal; during the growing season, seize the key periods for pesticide application, pay attention to rotating chemicals, and strictly implement the pre-harvest interval. Before harvest, even more care should be taken to control pesticide use to ensure the fruit is safe to eat.

Harvest at the Right Time, and Pay Attention to Both Production and Sales

Wendan pomelo emphasizes "timely harvesting." Harvest too early, and the flesh is rather sour with insufficient juice; harvest too late, and it does not keep well. Generally speaking, when the rind turns from deep green to yellow-green and the flesh is plump and slightly springy, it can be harvested in batches. Specific standards vary slightly depending on the production area and variety. In recent years, many production areas hold picking experiences, production-sales matchmaking, and other activities during the Wendan harvest season. Fruit growers may wish to pay more attention to notices issued by local agricultural departments and actively sign up to participate. This allows them not only to learn techniques and broaden their horizons, but also to take the opportunity to expand sales channels and sell good fruit at a good price.
