Gardeners' Notes:

Positive Krtka On May 23, 2013, Krtka from Lynchburg, VA wrote:

Although classified as loose leaf, this lettuce forms a very tight head of thick, crisp, heavily savoyed leaves. Delicious and sweet! Bright green heads add fabulous crunch to spring salads. I grow it every year. When we give heads of Green Ice lettuce to friends, they always want to know what variety it is because the flavor is outstanding. Not very heat tolerant. Can be grown in spring and fall.

I had great success growing this lettuce, even though I've never been very good at growing other types in the past. This one germinated easily, grew well and a lot, tasted great.

This is one of the few disappointments I've had growing lettuce. I found Green Ice to be difficult to germinate and to grow. Also, the heads were quite small, almost like a miniature Salad Bowl type. Not worth the trouble.

Very easy to grow. Sow seeds in early spring and again after the very hot days of summer are over. In cooler climates, you can make 2 to 3 spring plantings, timed 2 weeks apart.

To harvest, pull the whole plant or just snap off the outer leaves.
