Watch for celery leaf blight/cercospora leaf spot and damping-off-like seedling collapse, which show up as brown to gray speckling on leaves and can spread quickly in cool, wet weather. Keep airflow by spacing plants properly, water at the soil line (not on foliage), and remove badly spotted leaves early; if problems persist, switch to a labeled fungicide for celery/leaf blight and repeat per the label after cool, humid periods. Also check for aphids on new growth and rinse them off, then release or encourage beneficial insects if populations stay low.

Harvest at about 90 days from sowing/transplanting window for your timing, when plants form full-size, crisp roots and tender, flavorful stalks. For a crisp eating quality, pick outer stalks first once they’re thick enough for use, then continue harvesting as the rest catch up. If you see stalks becoming stringy or very tall and loose, it’s past peak tenderness—start harvesting immediately.
