When growing indoors you may want to take a few other things under consideration that you otherwise might not think about when growing outdoors. For one, you need to lessen the amount of drainage indoor to make sure you don’t ruin your tabletop or windowsill by letting your potted basil drain on it. Also, when you let your plants sit in water they will rot and be ruined. Instead, place your potted plant on top of a saucer, liner or drain pan to catch water and protect you surface.

Whether you decide to use artificial or natural light, make sure your basil gets plenty.
Although clay pots help with drainage, they can also dry out quickly. This is especially important to consider if you live in a dry climate or are growing herbs indoors during winter when the heater is running. Instead, try a glazed or plastic container that won’t dry out as quickly as clay.
Choosing the Right Soil
Basil is a unique herb in that it prefers a nutrient-rich, slightly acidic soil that drains easily. It’s best to select a light potting mix that contains a high percentage of organic matter. You need to make sure that the soil holds moisture but is never soggy. When purchasing your soil, choose a mixture that is formulated for foliage plants opposed to one formulated for flower production. Flower production of basil plants should always be avoided.
