What are the precautions for growing celery in greenhouses in autumn?
Celery is a fast-growing leafy green vegetable with very strong adaptability. Greenhouse celery is generally raised as seedlings in summer and planted out in autumn. If planting now, you need to hurry with the seedling raising.
Greenhouse celery is mostly sown with dry seeds, though sowing after sprouting can also be used. The seedbed should be watered thoroughly; while the water has not fully drained away, level the seedbed with fine soil and sow the seeds evenly over the surface of the seedbed.
After sowing, greenhouse celery should be covered with shade and rain protection equipment. After the celery emerges, gradually reduce the shading time and increase the light time. The seedbed should also be sprinkled with water regularly. When the celery seedlings grow to 4-6 leaves, water should be properly controlled, and pests and viral invasion should be prevented and controlled in time, to prevent damping-off disease in the celery seedlings.
Before lifting the celery seedlings in the greenhouse, the seedbed should be watered thoroughly, as this will help pull up the celery seedlings with their roots intact. According to the size of the seedlings, grade the celery seedlings and plant them in separate beds, and plant them as single plants. The planting depth should also be appropriate, and after planting is completed, water the planting water immediately. Chen Long
