Article: When it comes to choosing soil to grow the lemon balm in, opt for a rich, well-drained clay or sandy loam. Ideally, you want the soil to have a pH between 6.0 and 7.5. Soilless potting mixes, vermiculite, perlite, coco peat, and rockwool are also ideal mediums for growing lemon balm as long as you fertilize them regularly. Lemon balm doesn’t require a lot of fertilizer for healthy growth. However, it’s still a good idea to mix in some slow-release fertilizer into the soil when you plant to ensure that the plants receive a steady supply of nutrients over time.  A slow-release fertilizer with a 19-19-19 ratio of nitrogen, phosphorus, and potassium is ideal for growing lemon balm. Be sure to read the fertilizer label to determine the proper amount to add to your lemon balm plants and how often you need to reapply it. When it comes time to place the lemon balm in the soil, proper spacing is key because it can spread quickly as it grows. Place seeds 1⁄4 inch (0.64 cm) beneath the soil and seedlings at the same depth that they are in their containers, and space the plants so they’re at least 12 to 15 inches (30 to 38 cm) apart. You may need to thin the seedlings as they grow so there is enough space between the plants.
