Thai Towers

Basil

30d to harvest

Fragrant as a summer breeze, ‘Thai Towers’ basil rises with upright, tower-like stems that hold their form beautifully—an aromatic feast of sweet anise and bright clove over a clean, peppery green snap. Leaves are small to medium and tender, with a softly crinkled, velvety surface that releases its signature perfume at every touch. Grow ‘Thai Towers’ for fresh, fragrant use and for bold, aromatic sauces where its lively flavor and upright habit shine.

Frequently Asked Questions

What pest or disease is most likely on Ocimum basilicum (Thai Towers) indoors or in warm weather, and how do I treat it?

Basil downy mildew and leaf-spotting fungi can quickly spread on Ocimum basilicum, especially with warm, humid conditions and wet leaves. Start by removing affected leaves, then increase airflow and water only at the soil line; avoid splashing the foliage. If the disease keeps progressing, switch to a labeled fungicide appropriate for basil (follow the label exactly) and stop harvesting until the re-entry interval is met.

How do I tell when Thai Towers basil is ready to harvest?

Harvest when plants are about 30 days from sowing/transplanting and have developed several sets of true leaves (typically 6–8 inches tall). Pinch or cut just above a leaf node to encourage branching; take no more than one-third of the plant at a time. For best flavor, harvest in the morning before heat triggers bitterness, and keep harvesting regularly to delay flowering.
