Frequently Asked Questions

How often should I water spinach (Spinacia oleracea) during its main growing phase to avoid bolting or poor growth?
During the main growth period, keep the soil consistently moist but not waterlogged—aim for evenly damp soil 1–2 inches down. Typically water about 1 inch per week total, split into 2–3 waterings during warm or windy weather, and reduce slightly as days cool. Inconsistent moisture can stress spinach and speed up bolting, especially when temperatures rise.
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.

Expert Note
