When to Start Basil Seeds Indoors

You can start basil seeds indoors at any time of the year, as long as you have a warm environment and enough light. However, late winter or early spring is ideal if you want to transplant them outdoors later.

What You’ll Need

• Organic basil seeds

• 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.
