Butterhead lettuce 'Buttercrunch'

Keep moisture constant, drying out will trigger bolting; avoid watering in the heat of the day; growing under shadecloth is beneficial in hot areas.
Hot weather will develop bitter flavors.¹

Buttercrunch likes a position of partial sun and remember to water often. Keep in mind when planting that Buttercrunch is thought of as hardy, so this plant will survive close to or on freezing temperatures. Ensure your soil has a ph of between 6.2 and 6.8 as Buttercrunch is a weakly acidic soil loving plant.

Sow your seeds indoors, about 3-4 weeks before planting out. Cover seed lightly or just push into starting mix. Seed germinates best at a temperature of 60 to 68 degrees F. Seeds should germinate between 6-10 days

Try to aim for a seed spacing of at least 5.85 inches (15.0 cm) and sow at a depth of around 0.2 inches (0.5 cm). Soil temperature should be kept higher than 5°C / 41°F to ensure good germination.

By our calculations, you should look at sowing Buttercrunch about 25 days before your last frost date.

Lettuce is a fairly hardy plant and can be transplanted after danger of deep frost usually several weeks before the last light frost date. Transplant lettuce for the fall about 30 days before first frost date. Transplant seedlings between 3-4 weeks after sowing seed and fertilize with a high nitrogen mix.

Ensure that temperatures are mild and all chance of frost has passed before planting out, as Buttercrunch is a hardy plant.

By our calculations, you should look at planting out Buttercrunch about 32 days before your last frost date.

This variety tends to be ready for harvesting by early summer.
