Fresh basil is a kitchen staple, but buying plastic clamshells of it at the grocery store gets expensive fast—and they wilt within days. Growing your own fresh basil indoors on a sunny windowsill or under a grow light gives you a continuous supply of aromatic leaves for cooking, right in the middle of your apartment.
1. Starting from Seeds or Cuttings
You have two great ways to start indoor basil:
From Seed: Sprinkle basil seeds lightly over moist, well-draining potting mix, cover them with a thin layer of soil, and keep them warm. They typically germinate within 7 to 14 days.
From Stem Cuttings (The Fast Track): Take a 4-to-6-inch cutting from a fresh store-bought basil stem, strip the leaves from the bottom half, place it in a glass of water, and watch roots sprout within a week before planting it in soil.
2. Lighting and Temperature Requirements
Basil is a sun-worshipping plant that needs plenty of energy to produce those flavorful leaves.
- Place your pot on your brightest south- or west-facing windowsill.
- If natural light is lacking in your apartment, position an LED grow light about 6 inches above the plant for 10 to 12 hours a day.
- Keep it away from chilly drafty windows or blasting air conditioning vents, as basil prefers warm indoor temperatures.
3. Smart Watering and Harvesting
- Watering: Let the top inch of soil dry out between waterings. When you water, do it thoroughly until it drains out the bottom, but never let the pot sit in standing water or the roots will rot.
- Pruning for Bushiness: Never just pluck leaves off the top. Pinch the stem right above a pair of lower leaf nodes. This forces the plant to branch out into two new stems, giving you a bushier, higher-yielding plant instead of a tall, spindly stalk.
