You can place them in the existing landscape. I planted a bay laurel as part of our foundation plantings along with lemon balm. The rest of the herbs are mixed in with butterfly plants and vegetable plants in a large bed that is out in the sun. Most herbs, such as rosemary, thyme and Greek oregano, need at least six hours of sun each day and well-drained soil. If you are starting a new garden by preparing a bed, mix in a generous amount of mushroom compost or homemade compost to condition the soil before planting.
Most mints spread very quickly.
For this reason, I confine mine to an antique black kettle on my front steps. To keep your herbs looking nice, water regularly until established and during times of drought. Fertilize lightly with a slow-release fertilizer. I use organic fertilizer, which also builds the soil while feeding the plant. Too much fertilizer promotes fast, weak growth that will not be as flavorful.
