How to manage celery when it finds hollow

Celery hollow is a phenomenon of tissue aging, starting from the base of the petiole and gradually developing upward, white flocculent cork-like tissue appears in the hollow part.

Prevention:

1. Choose solid and good celery varieties for planting in sandy loam soils rich in organic matter, strong water retention and fertility, and good drainage and irrigation conditions. The pH of the soil is neutral or slightly acidic. Avoid planting in clay or sandy soil.

2. Celery likes cold and humid environmental conditions. For celery cultivation indoors, the temperature during the day should be 15℃~20℃, the highest temperature should not exceed 25℃, and the temperature should be around 10℃ at night, not lower than 5℃. Properly ventilate at ordinary times to reduce air humidity.

3. Apply foot fertilizer and spread evenly. After planting, spray the new high-lipid film to shorten the slow seedling period and increase the survival rate. The top dressing in the growth period is mainly based on quick-acting nitrogen fertilizer, combined with potassium fertilizer, each time about 20 kg, and top dressing once every 15 days or so. In order to prevent boron deficiency and hollowness, 0.3%~0.5% borax solution and vegetable Zhuangshaoling can be sprayed on the leaf surface. Pour small water frequently. Always keep the border soil moist. In addition, pay attention to spraying the new high-lipid film in time to form a layer of polymer film to prevent pests and diseases.
