Frequently Asked Questions

What’s the most common disease issue for Lactuca sativa (kalura) and how do I treat it?

A common problem is downy mildew (often seen as pale yellow patches on the upper leaf surface with a fuzzy growth underneath). Remove and discard badly affected leaves, improve airflow around plants, and avoid wetting the foliage when watering. If conditions stay humid, use an appropriate labeled fungicide for lettuce and follow label timing closely.

How often should I water kalura during the main growth phase?

During the main growth (roughly weeks 3–8), keep soil consistently lightly moist—about 1 inch of water per week total, adjusted for your weather. Water at the base early in the day so the leaves stay dry, and aim for evenly moist soil rather than letting it swing to dry then soggy. If you see leaf edges browning or bitter-tasting leaves, it usually points to irregular moisture.

How can I tell when kalura (Lactuca sativa) is ready to harvest?

Harvest when plants reach about 60 days from sowing (or sooner for baby leaves) and leaf size is fully developed for your target type. For crisp, mild leaves, pick in the morning before heat triggers bitterness and bolting; outer leaves can be snipped first for a continued harvest. If the center begins to elongate or you see a flowering stalk forming, harvest immediately because quality drops fast.

Crisp as morning air, Kalura romaine forms tall, elegant heads with a cool, refreshing crunch and a gently sweet, green-forward flavor. The leaves are satisfyingly sturdy—deeply ribbed and beautifully textured—holding their shape for standout salads and vibrant garnishes. Grow Kalura for a dependable 60-day harvest that rewards with clean, upright heads and a fresh, garden-bright bite.

Sowing Tips

Transplant Conditions

Wait until soil reaches 40°F and nights stay above 35°F before moving outdoors. Harden off for 6 days first.

Expert Note

For large romaine heads, keep soil evenly moist and avoid letting plants dry out—irregular watering in warm weather can cause bitterness and early bolting.
