Frequently Asked Questions


Why are my All Red plants developing curled, distorted leaves and tiny green insects, and what should I do?
This is commonly caused by aphids, which feed on soft growth and can trigger leaf curl on All Red (a fast crop, so damage shows quickly). Spray the plants with a strong stream of water to dislodge aphids, then apply insecticidal soap or neem every 5–7 days until new growth is clear of insects. Keep weeds down around the bed because they can harbor aphids and slow recovery.
How often should I water All Red during the 30–35 day growing window?
Water to keep the top 1–2 inches of soil consistently moist, not soggy—typically about 1 inch of water per week total, split into 2–3 waterings during warm spells. Check by pressing a finger into the soil near the roots: it should feel like a wrung-out sponge; if it’s dry to 2 inches down, water again. Avoid letting the soil dry out completely and then flood, which can reduce growth and tenderness.
How do I tell when All Red is ready to harvest at about 35 days?
Harvest when the roots are fully colored and reach the variety’s typical size for All Red—check the bed by gently pulling one plant and looking at the red portion at the soil line. If you see tops looking lush but the roots aren’t enlarging, wait a few more days; if roots are getting hard or woody, harvest promptly. For best flavor and texture, pull in the morning and replant any remaining plants back to their original depth.
Botanical illustration of All Red

Velvety, deep all-red foliage unfurls into tender, upright leaves that feel lush and substantial in the hand. “All Red” delivers a sweet, mildly earthy flavor with a crisp-tender bite—ideal for quick, vibrant harvests at about 35 days. Grow it for bold color in salads and sautés, or for steaming and stir-fry greens that stay richly red as they cook.

Expert Note

For the best deep-red color and tenderness, keep growth steady with consistent moisture and avoid letting plants get stressed by heat or drought.
