Ocimum tenuiflorum (Holy basil, Tulasi) 圣罗勒 (15cm/17cm pot)

Ocimum tenuiflorum, also known as Holy Basil or Tulasi, is a fragrant herb native to the Indian subcontinent. Revered for its medicinal and spiritual significance, it grows as a small, bushy plant up to 60 cm tall, with green to purple-tinted, aromatic leaves. It produces small purple or white flowers and is valued for its therapeutic properties and culinary uses. Holy Basil thrives in tropical climates and is often used in gardens or herbal remedies for its health benefits and distinctive flavour.

Plant Care Guide
Light Requirements: Holy Basil thrives in full sun, requiring at least 6 hours of direct sunlight daily for optimal growth. If grown indoors, place it near a bright window with plenty of sunlight. In shadier spots, the plant may become leggy and less productive.

Watering: Water regularly to keep the soil evenly moist but not soggy. Allow the soil to dry slightly between waterings, especially in hot weather. Ensure good drainage to prevent root rot, and avoid standing water around the plant.

Soil and Drainage: Holy Basil prefers well-draining, fertile soil rich in organic matter. Use loamy soil, and if planting in pots, ensure there are drainage holes. Adding compost will enrich the soil and support healthy growth. Mix in perlite or coarse sand for improved drainage in heavy soils.

Fertilising: Feed the plant with a balanced, slow-release fertiliser or liquid fertiliser. Avoid over-fertilising, which can result in excessive leafy growth at the expense of flavour. Organic compost can also be used to provide nutrients.

Pest and Disease Management: While Holy Basil is generally pest-resistant, it can attract aphids, whiteflies, or spider mites. Check the leaves regularly and treat with organic insecticides if needed. Watch for fungal issues like powdery mildew, particularly in humid conditions. Ensure good air circulation and avoid overhead watering to minimise fungal risk.

General Care: Holy Basil is easy to care for with regular pruning to remove dead or yellowing leaves. Prune the plant to maintain a compact shape and encourage new growth. It can be grown in containers or directly in the ground, thriving with proper sunlight, moisture, and well-draining soil.
