Which greens should I grow?
Lettuce, spinach, kale, chard, collards, arugula, and Asian greens differ in how they handle heat, cold, and bolting. Some are cut once, while others can be picked over and over. Choose types that suit your climate and buyers.
Start with a few reliable types and expand. Ask local growers which varieties resist bolting and disease in your area.
Mix colors and textures if you sell at a market. A table of different greens draws more attention than one type, and customers often buy several kinds together.
- Lettuce and spinach prefer cool weather
- Kale and collards tolerate more cold
- Chard handles heat better than many greens
- Check varieties for bolting resistance
When should I plant?
Most greens prefer cool weather and grow best in spring and fall. Heat makes many of them bolt, which means they send up a flower stalk and turn bitter. Plant in succession for steady supply, and use shade cloth or heat tolerant varieties in warm periods.
Check local frost dates with your extension office and plan around them.
Shade cloth over beds in warm spells can lower stress, and planting heat sensitive crops where afternoon shade falls is a free way to extend the season.
How do I feed and water them?
Greens grow fast and respond to good fertility, especially nitrogen, but too much can raise disease risk and reduce quality. Use soil tests to guide you. Keep water even, since dry spells cause bitterness and tip burn, and wet leaves for long periods encourage disease.
Drip or careful overhead watering early in the day suits most greens.
Mulch between rows to keep soil from splashing onto leaves. Splashed soil carries disease and makes washing harder, so a clean leaf surface saves time later.
What pests and diseases are common?
Aphids, flea beetles, slugs, caterpillars, and leaf miners feed on greens. Diseases like downy mildew and rots can spread in wet or crowded conditions. Row covers are often the first defense against insects, and spacing and airflow help against disease.
Because greens are eaten raw, take extra care with any product you use. Follow the label for waiting periods, and contact your extension office for guidance.
Check for slugs in the early morning or after rain, when they are active, and look for eggs and young caterpillars on the undersides of leaves while they are still small.
- Use row covers early
- Space plants for airflow
- Scout the undersides of leaves
- Follow label waiting periods exactly
How do I harvest?
Cut or pick in the cool morning with clean, sharp tools. For cut and come again crops, leave the growing point so plants can regrow. For heads, cut at the base. Handle leaves gently, since they bruise easily.
Put harvested greens in shade right away and cool them as quickly as possible. Heat is the enemy of freshness.
Keep a stack of clean harvest bins and a shaded place to work. Greens left on a hot tailgate wilt in minutes and cannot be restored.
How do I wash and keep them fresh?
Use clean, potable water and clean containers. Remove damaged leaves, rinse to remove soil, and drain or spin dry. Keep cold and humid according to extension storage guidance.
Wash hands and sanitize tools and surfaces, since greens are often eaten raw. Ask your state agriculture department about food safety rules for selling greens.
Check storage temperatures with a thermometer and keep greens away from ripening fruit, which can speed yellowing. Ask your extension office for storage guidance by crop.
- Use potable water and clean bins
- Dry or spin leaves well
- Cool quickly and keep cold
How do I plan for steady supply?
Sow small amounts every week or two, mix varieties, and keep records of what held up in heat and cold. Use extension season extension guidance for tunnels or covers if you want a longer window.
Greens are a good crop to learn on because mistakes show up quickly and you can replant fast.
Write down which sowing dates held up and which bolted. A few seasons of notes give you a local calendar better than any generic guide.
- Sow every week or two
- Rotate bed locations yearly
- Keep notes on what bolted and when
Key takeaways
- Plant greens in cool seasons and watch for bolting.
- Keep water even and fertility balanced.
- Use row covers and airflow to limit pests and disease.
- Cool and wash greens carefully since they are eaten raw.
