How to grow basil
Basil is an annual herb that thrives when summer heat arrives, pumping out fragrantly delicious leaves. Planting basil typically yields a harvest of leaves flavored with hints of anise, mint, and clove, but you can also try growing basil with tones of cinnamon or lemon. You'll find leaves in a variety of sizes, flavors and colors. If you like cooking Italian and Asian cuisine, you should try growing basil.
Here's how to grow basil in your home garden.
You can start with young plants or grow basil from seed. You can sow seeds directly into soil outdoors after all danger of frost has passed, or start seeds indoors about six to eight weeks before your region's average last frost date, using Miracle-Gro® Seed Starting Potting Mix. Sow basil seeds one-half inch deep, placing 3 seeds per seed-starting cell . Germination takes 7 to 14 days. After the first set of true leaves appear (these will be teardrop-shaped), thin seedlings by using scissors to snip off all but the strongest seedling in each cell. If necessary, transplant seedlings into larger containers until they're ready to go into the garden. In the garden, space plants 12 to 18 inches apart, depending on variety. If starting seeds directly in the garden, sow seeds one-half inch deep, one inch apart, and thin to 12-18 inches apart after the first set of true leaves appears. If growing in a pot, choose a 12-inch container or larger.
Water well after planting.
Pinch basil plants when they're 4 to 6 inches tall, removing the center set of leaves at the growing tip. This will encourage branching, resulting in a bushier plant. Pinch basil shoots again when they have added another 6 inches of growth.
Basil plants need consistent soil moisture to yield well. When the top inch of the soil is dry, you need to water. Containers need to be watered more frequently than in-ground gardens.
Mulch around plants with 2 to 3 inches of Scotts® Nature Scapes® bagged mulch, straw, shredded leaves, pine straw, or untreated grass clippings. Mulch helps reduce weeds and keep soil moist, which can reduce watering chores.
Basil plants need a steady supply of plant food to fuel leaf production. Starting about a month after planting, feed your plants with Miracle-Gro® Water Soluble All Purpose Plant Food, following the directions on the label. Continue to feed plants every 2 weeks throughout the growing season.
Sometime around mid-summer, plants will start flowering. As soon as you see a flower bud, pinch it off. If flowers are allowed to grow, leaf flavor will change (not for the better) and leaf production will start to slow.
Basil is extremely cold-sensitive, typically showing signs of cold damage at temperatures below 42°F. Harvest plants heavily if frost is in the forecast.
Start harvesting individual leaves as soon as plants are 6 to 8 inches high. Pinch individual leaves or snip stems. To store basil inside for a few days, keep freshly clipped sprigs in a vase of water at room temperature. Do not refrigerate basil; the cold air turns leaves brown. You can, however, freeze chopped basil in cubes of water or olive oil.
