| According to Charlie Nardozzi writing in "Vegetable Gardening for Dummies," head lettuces need cool temperatures (50-60 degrees F) throughout the growing season. In your area, try planting seed indoors in July to transplant out in August or September. Keep soil consistently moist and feed the plants with fish emulsion every 3 weeks. By fall's cool days, you should have heads formed. Try some of the many loose-leaf varieties for earlier in the year, so you don't have to worry about heads forming. Good luck! |
