Grow & Care for Basil Plants


Basil grows as a summer annual herb. It produces fragrant, flavorful leaves often used to complement tomato-based foods. The herb can't tolerate frost and grows best during the warm days of summer and fall in nearly all climates. Basil produces ample foliage with only minimal care.

Planting Basil

1

Sow two basil seeds in moist potting soil inside a 2-inch-diameter seedling pot. Plant the seeds approximately six weeks before the last expected frost date. Cover the seeds with a 1/4-inch layer of soil.

2

Cover the pot with a plastic bag to retain the soil moisture during germination. Set the pots in a warm area indoors until the seeds sprout, which can take up to seven days. Basil doesn't require light to germinate.

3

Remove the plastic bag and move the pots to a location that receives at least six hours of daily sunlight after the seeds sprout. Water the basil when the soil surface dries.

4

Pinch out the extra seedlings so only one seedling remains in each pot after the plants produce their second set of leaves. Transplant the seedlings outdoors two weeks after frost danger passes.

Outdoor Care

1

Amend a full-sun garden bed with a 1-inch layer of compost, digging it into the top 6 inches of soil.

2

Lift the basil seedlings out of their pots and plant them in the prepared bed at the same depth they were growing at previously. Space the basil plants 8 inches apart.

3

Water basil once weekly, providing about 1 inch of moisture via irrigation or rainfall. Basil grows best in soil that remains moist without becoming soggy.

4

Pinch off the tip of each stem every three weeks to keep the plants bushy and to prevent flowering. Alternatively, snip back the plant to half its height every two or three weeks when harvesting. The foliage tastes best when the plants aren't allowed to flower.
