Planting

How to Grow

Tuck seeds 1/4 inch deep into moist, well-draining soil in a warm location.
Mist cuttings regularly to maintain humidity and promote rooting over 4-6 weeks.
Transplant seedlings outdoors after the danger of frost passes, typically 2-3 weeks after last frost.
Space plants about 12 inches apart to ensure good air circulation.
Water consistently, keeping soil moist but not waterlogged, especially during hot months.
Harvest leaves frequently to encourage bushier growth and prevent flowering.

Pro Tip

Pinch off flower buds to prolong leaf production and maintain flavor intensity.

Common Questions

African Blue Basil questions

What zones can African Blue Basil grow in?

African Blue Basil is hardy in USDA Zone 10. Inside that range it survives winter in the ground; outside it, grow it as an annual or a container plant you protect.

Is African Blue Basil deer resistant?

Not reliably. Deer may browse African Blue Basil, especially tender spring growth — plan on repellents or fencing where pressure is high.

When does African Blue Basil bloom?

African Blue Basil typically blooms in late summer through early fall. Exact timing shifts a week or two with your zone — Sow's bloom calendar maps it to your garden.

Does African Blue Basil need full sun?

African Blue Basil does best in full sun to part shade. In hot climates, afternoon shade keeps blooms fresher longer.
