Frequently Asked Questions

What’s the most common disease issue for spinach (Spinacia oleracea) and how do I prevent it?

Spinach commonly gets downy mildew, which shows as yellow patches on top leaves and fuzzy gray-purple growth on the undersides. Prevent it by watering at the soil line (not overhead) and spacing plants so leaves dry quickly; remove and discard infected leaves promptly. If it’s actively spreading, use a labeled fungicide that’s approved for leafy greens and downy mildew, applied according to the label.

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

Harvest when leaves are large enough to use—usually around 45 days—by cutting outer leaves about 1–2 inches above the soil. Look for healthy, tender texture and avoid harvesting leaves that are tough or severely thickened, which can indicate early bolting. You can do repeated cut-and-come-again harvests as long as the plant keeps producing new leaves.
