Lemon balm, like several other members of the mint family, is a useful and edible plant that is easy to grow and beautiful to look at. However, it has another of mint's characteristics: a rampant and often invasive growth habit. So choose your area for planting carefully. Lemon balm makes a fragrant herbal tea that is tasty consumed either hot or cold and combines well with other herbs in tea blends and potpourris.
Moisten soilless potting mix or finely sifted, good quality potting soil until it is damp.
Transfer a shallow layer of the soil into a seed tray or pot. Firm the soil gently to settle and remove entrapped air.
Scatter lemon balm seeds across the surface of the soil, and gently press them in with a flat block of wood or similar object. Top with a light sprinkling of fine soil to barely cover the seeds.
Keep the tray or pot moist and in a warm place, about 72 degrees F, for two to three weeks until seeds sprout. They may take awhile to germinate, so be patient. Do not allow soil to dry out, but do not overwater or the seeds may mold and not sprout.
Transfer the tray or pot to a sunny location, or put a grow light about 2 inches above the seedlings until sprouts have at least two true leaves.
Put dampened soilless mix or fine potting soil in several 3-inch peat pots.
Transplant seedlings carefully to the pots by using a narrow trowel or butter knife to loosen the soil, then gently grasping each seedling by the leaves and pulling it straight up.
Make a narrow hole in each peat pot with your finger, and place the seedlings' roots down into it so it is positioned slightly deeper than it was in the tray. Firm the soil around the roots.
Place pots near a window or under lights to grow until after the last frost date for your area.
Setting Out in the Garden
Use a trowel to dig holes to the depth of the peat pots and 12 to 15 inches apart in a freshly prepared garden bed. Lemon balm prefers slightly alkaline soil and full sun to partial shade.
Place each seedling, pot and all, into each hole and firm the soil around it.
Keep moist until they are fully established.
