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.

Sowing Tips

Soil Temperature

Direct sow or transplant when soil at planting depth holds 40°F for reliable germination and early growth.

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.
