Frequently Asked Questions

What’s a common disease or pest for Spinacia oleracea, and how do I fix it?

Spinach commonly suffers from downy mildew when leaves stay wet and air is humid. Remove and discard infected leaves, water at the soil line in the morning, and improve airflow by spacing plants so the canopy isn’t dense. If the problem keeps recurring, use a labeled fungicide appropriate for downy mildew on leafy greens and avoid overhead watering for the rest of the cycle.

How can I tell when Spinacia oleracea is ready to harvest?

Harvest at about 35–45 days when leaves are tender and the plant is forming a good rosette. Pick outer leaves first for a cut-and-come-again harvest, leaving the center to keep producing; for a one-time harvest, remove the whole plant when it reaches full size. If leaves become coarse or the plant bolts (shoots a flower stalk), flavor drops quickly—harvest immediately.
