Frequently Asked Questions

Why are my butterhead (Bibb) leaves getting mushy and brown at the soil line, and what should I do?

Mushy, brown bases on Bibb are often caused by damping-off or early rot from consistently wet soil and poor airflow. Remove affected plants, improve drainage, and water only at the soil surface (not on leaves). Space plants closer to label spacing and thin promptly so heads form in drier, better-ventilated conditions.

How often should I water butterhead (Bibb) during the main growing phase to prevent bolting and keep heads tender?

During head formation, keep the soil evenly moist with about 1 inch of water per week, adjusting to rainfall and heat. Water deeply 1–2 times weekly rather than frequent light sprinkles, and check that the top 1 inch of soil stays slightly moist but not soggy. If the soil dries out fully between waterings, Bibb can stress and become tough or bolt.

When is butterhead (Bibb) ready to harvest, and how do I know the heads are ripe?

Harvest at about 55 days when heads feel firm but still tender and the leaves are flexible (not crunchy) when pressed gently. Look for the center to be well formed with leaves that are pale to light green, depending on your variety. For best flavor, cut in the morning and harvest before the head starts to elongate upward toward bolting.
