Indoor Basil Care: Light, Water, Fertilizer, and Flower Management

Year-Round Fresh Basil Indoors

Fresh basil > dried for flavor. Indoor growing suits yardless gardeners and winter harvests. Standard equipment from garden stores suffices.

Setup and Planting

Step 1: Pot and Mix

6-inch pot, soil-less houseplant mix (excellent drainage—prevents root rot).

Step 2: Establish Plant

Seeds: 1/pot, ½ inch deep, 2x daily water, 14-day germination.
Nursery plant: Slip from pot, bury in your mix.
Cutting: 4-inch branch in water until roots, then pot.

Step 3: Light

Full sun ideal. South window or fluorescent grow lights (16 hrs/day, 2–3 inches above plant, raise as it grows).

Step 4: Water

Lots of moisture, but roots need dry-down. Water when mix turns flaky/crumbly. ~Every 2 days depending on humidity.

Step 5: Fertilize

10-10-10 liquid vegetable fertilizer per label. Ensures foliar production—critical for leaf herbs.

Step 6: Remove Flowers

Flowers drain energy. Pinch off for lush foliage.

A sunny windowsill or light setup yields fresh basil 12 months a year.
