Tips for March
- Test old seeds before you sow. Roll 10 seeds in a damp paper towel, put it in a plastic bag somewhere warm, and count the sprouts after a week. If 7 sprout, sow a little thicker. If only 2 do, buy new seeds.
- Sow two seeds per cell, then snip the weaker one. Not every seed sprouts, so sow two to a cell. If both come up, cut the weaker one at the soil line with scissors instead of pulling it, so the roots of the one you keep aren't disturbed.
- Water seedlings from below. Pour water into the tray under the cells and let the mix soak it up for 20 minutes, then tip out the rest. The top stays drier, which helps prevent damping-off.
- Stretching seedlings need more light. Tall, pale, floppy seedlings are reaching for light. Lower the lights to 2 to 4 inches above the leaves, and give them 14 to 16 hours a day.
For a garden in the middle of the country (around zone 6). Colder places run a few weeks behind, warmer ones ahead.
