What You’ll Need

Small seed-starting pots or trays
-
Organic potting mix (light and well-drained)
-
Spray bottle or watering can
-
A sunny windowsill or grow light
How to Grow Basil from Seeds Indoors
1. Prepare Your Containers
Choose pots with good drainage. Fill with a moist, well-draining potting mix enriched with compost or organic matter.
2. Sow the Seeds
-
Sprinkle 2–3 seeds per container or cell
-
Cover lightly with 1/4 inch of soil
-
Gently mist the top to moisten the surface
3. Provide Warmth and Light
-
Basil seeds need warmth (21–26°C or 70–80°F) to germinate
-
Place near a sunny window (6+ hours of sunlight) or under a grow light
-
Use a humidity dome or plastic wrap to retain moisture until germination
4. Watering
-
Keep the soil moist but not soggy
-
Use a spray bottle to prevent overwatering
-
Once seedlings emerge, water at the base to avoid damping off
5. Thinning Seedlings
After seedlings develop 2–3 sets of true leaves:
-
Thin to one strong plant per pot
-
Snip the extras at the base to avoid disturbing roots
6. Fertilizing
Feed your indoor basil every 2–3 weeks with a diluted organic liquid fertilizer to encourage lush growth.
Ongoing Basil Plant Care
-
Pinching: Regularly pinch off the top sets of leaves to encourage bushy growth and prevent early flowering.
-
Lighting: Rotate the pot weekly for even light exposure.
-
Temperature: Keep basil away from cold drafts and night temperatures below 15°C (60°F).
-
Pests: Watch for aphids and whiteflies; use neem oil or insecticidal soap if needed.
Harvesting Indoor Basil
-
Start harvesting once the plant is 6–8 inches tall
-
Pick leaves from the top for continual growth
-
Never remove more than one-third of the plant at a time
Frequent harvesting encourages the plant to grow fuller and produce more leaves.
