Water: Sweet basil thrives in tropical climates, requiring consistent moisture and humidity. It prefers slightly damp soil, needing watering twice a week. For optimal growth, cultivate sweet basil in well-draining soil, especially during active growth periods, to support its lush foliage and aromatic properties.
Fertilize: Fertilizing sweet basil is essential for robust growth. Use balanced fertilizers initially, then switch to high-nitrogen types. Apply every 4-6 weeks at quarter strength, adjusting for growth season. Avoid direct contact with the plant's foliage and watch for over-fertilization signs. Remember, moderation is key.
Pruning: Sweet basil benefits from regular pruning in early to late spring to encourage bushier growth and prevent flowering. Pinch off top leaves and remove flower buds to enhance foliage. Consistent pruning improves air circulation, minimizes disease risk, and extends the harvest, bolstering overall plant health and productivity.
Propagation: Sweet basil propagates effectively through cuttings, selecting healthy non-flowering shoots cut below a node. Remove lower leaves and place the stem in water or moist soil. While rooting hormone can aid, sweet basil usually roots well independently. Transplant once established, ensuring moisture and indirect light.
Repotting: Sweet basil requires excellent drainage in pots to thrive. Ensure the container has appropriate drainage holes to prevent waterlogging, which can lead to root rot and other issues.
