Why this variety

AA-93 — Ajmer Ajwain 93 — is the short-duration ajwain: it completes its season in about 150 days, which is 30 to 40 days earlier than other varieties. In Indian trials that earliness is a convenience; in Florida it is the whole strategy, because every week shaved off the season is a week less exposure to summer rain on ripening seed.

AA-93 is also one of the eight popular cultivars screened in seed-transmission studies, so it is a documented, grown-and-measured variety, not a name on a packet. For a first Florida ajwain trial, AA-93’s short season makes it the smartest pick of the group — the one most likely to actually finish.

How to grow

Direct-sow where it will grow, shallowly, at the hero spacing in a well-drained bed. Ajwain is an annual Apiaceae herb grown for its tiny, thyme-scented seed, and like its carrot-family cousins it prefers to be sown in place rather than transplanted.

In Florida, sow in fall as a dry-season trial: ajwain is a rabi (winter) crop in India, grown through the cool, dry months and ripened in dry heat. Summer rain on ripening umbels brings mold and shattering, so a fall sowing that finishes before the summer rains is the honest strategy.

Water & feeding

Water sparingly and at the base. Ajwain is a dryland seed spice: steady light moisture while plants establish, then back off as seed ripens. Overwatering in humid air invites blight and powdery mildew, and a raised bed that never puddles is the best insurance.

Feed lightly with compost at planting. Ajwain is not a heavy feeder, and excess nitrogen grows soft, disease-prone foliage. Trial spacing work found 45 by 30 centimeters productive — about the hero spacing — so give plants room to branch and breathe.

Common problems

• Powdery mildew and leaf blight — humidity diseases; space for airflow, water at the base, and ripen seed dry
• Shattering — seed falls when fully ripe; harvest when umbels brown, not after
• Aphids — cluster on flower heads; blast off with water
• Damping off — wet seedbeds; sow in well-drained soil and do not overwater seedlings

Harvest

Harvest at about 150 days when umbels brown and seed is firm. Cut, dry under cover, thresh over a tray, and winnow; store whole in a sealed jar.

Use AA-93 seed toasted lightly in oil for dal, vegetables, and breads. Its earliness does not change its flavor — ajwain is ajwain, thymol and all — it just changes whether you get a jar of it before summer, which in Florida is the difference that matters.

Saving seeds

AA-93 is a documented, open-pollinated variety, so it comes true from seed — save seed from your earliest, healthiest plants and it will grow up like its parent. Follow the full method in the Saving seeds section of the Ajwain guide.
