Which crops are best sown directly?
Root crops, beans, peas, corn and many greens and squash do well sown directly. Roots resent transplanting, and large-seeded crops sprout quickly outdoors. Some crops can go either way, and the packet or your extension office will say which is better.
Direct sowing saves the cost and effort of trays and lights, but it exposes seeds to weather and pests, so plan on some losses.
Keep some seed in reserve so you can fill gaps. Seed packets lose strength over time, so store leftovers cool and dry, and check the packed-for year or germination date if the packet lists one.
How do I know when the soil is ready?
Soil temperature matters more than air temperature. Each crop has a minimum and best range for sprouting, listed in extension publications and on packets. A soil thermometer inserted to seeding depth, checked in the morning, gives a reliable reading.
Soil should also be workable: crumbly when squeezed and released, not sticky or soaked. Working wet soil causes clods and compaction. Use your frost dates as a guide and let soil conditions make the final call.
Cold, wet spells after sowing can rot seeds, so watch the forecast and sow in small batches a week or two apart. Staggering also spreads out the harvest.
How do I prepare the seedbed?
Remove weeds and debris, loosen the top few inches and rake to a fine, level surface. Seeds need good contact with moist soil, and large clods leave air gaps. Add compost based on a soil test, not guesswork.
Mark rows with string or a board, and keep a label for each crop. Water the bed lightly before sowing if it is dry.
- Weeds and stones removed
- Fine, level surface
- Rows marked and labeled
- Soil lightly moist
How deep and how far apart do I sow?
A common guideline is to sow seeds at a depth related to their size, shallower for tiny seeds and deeper for large ones, but the packet gives the specific depth for each crop. Follow it. Spacing also varies, and thinning later brings plants to their final distance.
Cover seeds with fine soil and firm it lightly. Tiny seeds can be mixed with a little sand to spread them more evenly.
Mark the ends of rows with stakes so you can find the row after rain or when seedlings are slow to show. Use a straight board as a guide for neat rows.
How do I keep seeds moist until they sprout?
Seeds need steady moisture to germinate. A dry crust can block seedlings, so water gently, with a fine spray, and often enough that the surface does not dry out. A light cover of straw, board or row cover can hold moisture, but remove it as soon as seeds sprout.
Too much water can rot seeds and wash them out, especially on slopes. Aim for moist, not soaked.
Birds and rodents sometimes dig up seeds, and a temporary cover of netting or row cover can protect the bed until plants are up.
How do I thin seedlings?
Thinning feels wasteful, but crowded plants stay small and invite disease. Snip extra seedlings at the soil line instead of pulling, which can disturb neighbors. Thin when seedlings have a few true leaves, and again later if needed.
Many thinnings of greens and roots are edible, though only eat what you have grown yourself and positively identified as a crop. Check the spacing on the packet.
Water the row before you thin so the roots you keep are not pulled out with the ones you remove, then water again afterward.
- Thin when true leaves appear
- Snip, do not pull
- Water before and after
- Follow the packet spacing
What if nothing comes up?
Common reasons include cold or dry soil, seed sown too deep, old seed, crusting, birds, insects or washouts. Dig gently where seed was sown to look for sprouts or rotted seed. If it is early enough in the season, resow.
Test old seed by sprouting a few between damp paper towels before you sow. Keep notes on what failed, so you can adjust timing next year. Your extension office can help you identify problems specific to your region.
Keep a record of sowing date, soil temperature and the day seedlings appeared. A few seasons of notes make timing far more reliable than the packet alone.
Key takeaways
- Let soil temperature and workability guide sowing, along with frost dates.
- Prepare a fine, firm, moist seedbed.
- Follow the packet for depth and spacing.
- Keep seeds evenly moist and thin early.
