Frequently Asked Questions


How do I handle aphids or downy mildew on buttercrunch lettuce?
Check weekly under leaves for aphids; wash them off with a strong spray of water and, if needed, spot-treat with insecticidal soap, reapplying every 5–7 days until they’re gone. If you see downy mildew (grayish fuzzy growth on underside with yellowing upper leaves), remove affected leaves immediately and increase airflow—avoid wetting the foliage when watering buttercrunch.
How often should I water buttercrunch during its main growth (about weeks 2–7)?
Keep soil consistently moist but not soggy—water when the top 1 inch starts to dry, usually about 1–2 times per week depending on heat and container size. For headless/buttercrunch leaves, aim for deep, even moisture that reaches the root zone; if leaves develop bitterness or bolting starts, reduce water stress by watering more regularly during warm spells.
When is buttercrunch ready to harvest (55 days to maturity)?
Harvest when heads or clusters of crisp leaves are firm and the leaves reach full size, typically around 55 days after sowing. Use the “leaf feel” test—choose outer leaves once they’re thick and crisp; for whole plants, harvest before the center becomes too tall or bitter-tasting, as buttercrunch will bolt quickly in heat.

Sowing Tips

Transplant Conditions

Expert Note

Keep Buttercrunch cool and evenly moist; transplant into slightly cool conditions just before/during the window when nights are consistently above freezing.
