Sowing seeds in the garden

Broadcast them over a prepared bed or plant them in traditional rows

Many annuals, wildflowers, and vegetables can be seeded directly in the garden, either broadcast over a bed to give a planted-by-Nature look or sown in the traditional rows of a vegetable or cutting garden.

Certain easy-to-grow plants do best when sown directly in the garden, because they have delicate root systems or taproots that make successful transplantation from containers difficult. Such plants include sunflower (Helianthus), sweet pea (Lathyrus), love-in-a-mist (Nigella), nasturtium (Tropaeolum), and most wildflowers; and beans, carrots, corn, peas, and radishes.

PREPARING THE SOIL

Whether you're sowing a wildflower mixture or several kinds of annuals for a showy border, start by preparing the soil. Remove weeds, then loosen the soil and work in amendments with a spading fork, shovel, or rototiller. Add a complete fertilizer in the amount directed on the label. Finally, smooth the soil with a rake. If rain doesn't do the job for you, moisten the bed thoroughly a few days before you intend to plant. At sowing time, the soil should be moist but not soggy.

PLANTING IN ROWS

To grow vegetables or annuals in rows, prepare the soil as described above, but do not dig in fertilizer; it will be applied later.

Next, make furrows for the seeds, following the packet instructions for depth of furrows and spacing between them. If possible, lay out the rows in a north-south direction, so that both sides will receive an equal amount of sunlight during the day.

Form the furrows with a hoe, rake, or stick; for perfectly straight rows, use a board or taut string as a guide.  Now dig two furrows alongside each seed furrow ― one on either side, each 2 inches away from and 1 inch deeper than the seed furrow. Apply fertilizer in these furrows, following label recommendations for amount of fertilizer per foot of row. This technique puts the fertilizer where plant roots can best use it.

Sow seeds evenly, spacing them as the packet directs. You can tear off a small corner of the packet and tap the seeds out as you move along, or pour a small quantity of seed into your palm and scatter pinches of seed as evenly as possible. Larger seeds, such as beans, can be placed individually by hand.

BROADCASTING SEEDS IN A PREPARED BED

 Water the furrows with a fine spray; then keep the soil surface moist but not dripping wet until the seeds sprout. Thin overcrowded seedlings while they're still small; if you wait too long to thin, the plants will develop poorly, and you'll have a harder time removing an individual plant without disturbing those around it.

1. For a patterned planting, outline the areas for each kind of seed with gypsum, flour, or stakes and string. You may want to put a label in each area.

2. To achieve a more even distribution, shake each kind of seed (or an entire wildflower seed mixture) in a covered can with several times its bulk of white sand.

3. Scatter the seed-sand mixture as evenly as possible over the bed or individual planting areas; then rake lightly, barely covering the seeds with soil. Take care not to bury them too deeply.

4. Spread a very thin layer of mulch (such as sifted compost) over the bed to help retain moisture, keep the surface from crusting, and hide the seeds from birds.

5. Water with a fine spray. Keep the soil surface barely damp until the seeds sprout; once seedlings are up, gradually decrease watering frequency.

6. When seedlings have two sets of true leaves, thin those that are too closely spaced. Transplant the thinned seedlings to fill empty spaces in the bed.
