While basil does very well when grown outdoors, it can also be grown indoors, as long as it is provided with the right conditions. You can grow basil indoors as a herb to add more flavor to your dishes, or for aesthetic purposes. Here is a guide on the best way to grow the herb indoors:

1. Select the Ideal Area for Growing the Plant

Basil is a light lover. Place the plants near a west or south-facing window so that it can be exposed to sunlight. If this is not achievable, purchase growing light for your plants. If you are using fluorescent lights, place the lights 4” from the plant. High-intensity discharge lights are also ideal for providing light to the herbs. Switch them on for at least 12 hours every day.

2. Growing Container

3. Planting the Seeds

For basil to thrive well, it requires soil that is rich in nutrients, and well-draining. Potting soil will be a perfect choice for this. Put the soil in the container and add water to make it moist. Sprinkle the seeds on the container and cover them with dry potting soil. Use a spray bottle to add water to the soil surface.

Growing Basil From Stem Cuttings

  • Remove the leaves of a 4-inch basil stem on the bottom two inches.
  • Submerge the bottom part of the stem in water. After some time, the stem will develop roots. Let them grow up to 2 inches.
  • Plant the stem in a container with potting soil and add water.
  • After a week, the plants will start germinating. Continue adding more water to the plants. Add it directly to the soil surface and not on the leaves. Only add water when the soil feels dry.
