Thai Thai Prospera Active DMR Basil is a robust Thai basil cultivar bred for serious disease resistance, particularly against downy mildew and fusarium wilt, two adversaries that have plagued basil growers for years. This open-pollinated variety grows as a compact bush and reaches harvest readiness in about 70 days, offering gardeners a reliable supply of aromatic leaves for Thai cuisine. Space plants 4 inches apart for full, healthy specimens, and you'll have an herb that performs even in conditions where other basils falter.

The 'Prospera Active DMR' designation signals what this basil was engineered to do: resist the downy mildew that turns leaves gray and kills susceptible varieties mid-season. Combined with fusarium wilt resistance, this cultivar addresses two of the most frustrating diseases in basil growing. For gardeners in humid regions or those who've lost crops to fungal pressure, this variety offers a genuine second chance at reliable harvests. At 70 days to maturity, it's neither lightning-fast nor sluggish, giving you enough time to establish strong plants before peak harvest season.
Thai basil is essential to Southeast Asian cooking, particularly in Thai stir-fries, curry pastes, and aromatic broths where its distinctive anise-like notes shine. The leaves are harvested fresh and used to flavor dishes moments before serving, capturing their volatile oils at peak intensity. This variety's disease resistance makes it a practical choice for cooks who want a steady supply of fresh Thai basil throughout the growing season without the anxiety of crop failure.

Sow seeds indoors 6 weeks before your last frost date. Plant seeds 1/4 inch deep and maintain soil temperature at 70°F (21°C) for optimal germination. Transplant seedlings to the garden when they have developed 3 to 4 sets of true leaves.
Move hardened-off seedlings to the garden after all frost danger has passed and soil has warmed. Space plants 4 to 8 inches apart for healthy, full development.
Direct seed into the garden by planting seeds 1/4 inch deep, sowing 2 to 3 seeds per inch in rows spaced 18 inches apart. Firm soil over the seeds. Firm the soil well. Thinning is optional; allowing final spacing of 4 to 8 inches apart produces healthy, vigorous plants.
Begin harvesting lightly once plants have become established and have developed sufficient leaf mass. Harvest in the early morning when temperatures are cool and leaves are less prone to wilting. Pick leaves by hand, handling them gently to avoid bruising. For a full harvest before the plant flowers, cut the entire plant 4 to 6 inches above the ground to stimulate a second growth cycle.
Begin harvesting lightly once plants are well established, pinching leaves from the top to encourage branching and a bushier shape. Cut the entire plant 4 to 6 inches above the ground before flowering to promote a second flush of growth. Handle leaves carefully during harvesting to avoid bruising, which causes rapid deterioration.
