Quick Facts:
- Days to harvest: 70
- Hardiness: Frost-sensitive (cold kills it)
- Light needs: Full sun
- Water needs: Moderate (even moisture; don't let it dry out completely)
Planting:
- Start indoors 4–6 weeks before last frost. Do not direct sow until soil is reliably warm.
- Timing: Zone 8b — start indoors in March, transplant out after last frost (typically mid-May).
- Depth: 1/4 in, barely covered
- Spacing: 10–12 in apart
Care:
- Basil hates cold. Don't rush it outside — a cold snap after transplanting will stunt growth significantly.
- Pinch flower buds as soon as they form to keep the plant producing leaves. Once it goes to seed, leaf production stops.
- Consistent harvesting encourages branching and more leaves.
- Avoid overhead watering in the evening — basil is prone to fungal issues if leaves stay wet overnight.
Harvest:
- Harvest tips just above a leaf node to encourage branching.
- Don't take more than a third of the plant at once.
- Fresh use is best — leaves darken when refrigerated. Store cut stems in water at room temperature like a bouquet.
- For large harvests, freeze in olive oil in ice cube trays or make pesto immediately.
