If your gardening space is limited or if you have problems preventing your herbs from growing into each other's space (such as mints mixing and hybridizing), an easy solution is to partially bury containers in the ground. You may use any sort of container, the least expensive ones being the plastic liners or pots that your plants come in when you buy them from the nursery. You should cut out the bottom of the container and partially bury it, leaving about four inches above ground. Doing so creates a "fence" around the herbs and discourages invasions from weeds or nearby herbs. Fill the container to ground level, and plant your herbs.
Partially burying the container in the ground helps prevent the soil from drying out so quickly as it would in an above-ground pot. The containers may be placed at any distance from each other, and the spaces between them may be utilized for other herbs as well.
