Frequently Asked Questions

What pest or disease is most likely on spinach (Spinacia oleracea), and how can I control it?

Watch for downy mildew (often shows as yellow patches on top with gray-purple growth on the underside), especially in cool, humid weather. Remove infected leaves immediately, improve airflow with wider spacing, and avoid overhead watering. If you repeatedly see it, use a labeled fungicide for downy mildew on leafy greens and keep the bed evenly moist but not waterlogged.

How often should I water spinach during its main growth phase (about the first 3–5 weeks)?

Keep the soil consistently evenly moist from germination through the first full leaf harvest window, aiming for damp soil 1–2 inches down. In typical home beds, this often means watering 1–2 times per week, but more frequently in warm spells (part sun can still dry quickly). Don’t let soil swing from dry to soggy—spinach growth slows and bitterness increases if it repeatedly dries out.

How do I tell when Spinacia oleracea ‘Teton’ is ready to harvest?

Harvest at about 40 days when leaves are about 4–6 inches long with a tender, not tough texture. For cut-and-come-again, snip outer leaves at the base, leaving the center to regrow; avoid waiting until plants bolt or leaves become coarse. If you see flower stalks starting, harvest immediately and consider replacing the crop since quality declines fast.

Sink your spoon into Teton’s richly savoyed leaves—crisp, deeply quilted, and vividly green with a tender, sweet finish. At about 40 days, this market-class spinach forms an upright, leafy mound that stays flavorful and pleasantly crisp, even as the leaves mature. Grow Teton for fresh salads and quick sauté-style meals, or for silky green sauces and nutrient-packed additions that shine when steamed or blanched.

Sowing Tips

Transplant Conditions

Wait until soil reaches 40°F and nights stay above 32°F before moving outdoors. Harden off for 6 days first.

Expert Note

Start spinach early and keep it cool—success comes from avoiding heat (shade/row cover if nights warm up).
