The listing, Lemon Mint - 20 seeds has ended.
After all danger of frost has past, set lemon balm plants 20 to 24 inches apart in rich soil where it will receive some shade during the day. Lemon balm will remain green during mild winters, such as those in zones 9 and 10. This plant responds well to cutting, growing back twice as thick. Whenever your plant is looking tired due to drought, hail, insects, or other stress, just cut it back and let it rejuvenate itself with fresh, new growth. Lemon balm likes rich, moist, but well-drained soil with a pH of 6 to 7. Because most people harvest it continually for lots of leaves, lemon balm needs a little fertilizer. When planting, add a coated, slow-release fertilizer such as 19-19-19 at the rate recommended on the label, or work plenty of organic nutrients from compost, blood meal, or cottonseed meal into the soil.
