Frequently Asked Questions

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

Fungal leaf spot (often favored by cool, wet weather and crowded plants) can show up as dark, irregular spots with yellowing around them. Water at the soil line (not overhead), thin so leaves dry quickly after rain, and remove infected leaves promptly. If problems persist, use a label-approved copper or potassium bicarbonate spray to protect new growth.

How often should I water Spinacia oleracea during its main growing phase?

During the 30–45 day growing window, keep the top 1–2 inches of soil consistently moist but not waterlogged—spinach prefers steady moisture to avoid tough leaves and bolting. Water in the morning so foliage can dry, typically about 1 inch per week total from rainfall plus irrigation, adjusting to soil so you don’t see wilting or crusting. If your soil stays soggy or you see drooping with saturated soil, cut back and improve drainage.
