This variety is very popular in the United Kingdom, but largely unknown here in the US. The mini heads are about the size of a softball if they are grown with tight spacing, but grow quite a bit larger if given more room. Igloo produces standard sized curds of a pure white with strong outer leaves for good blanching. 30 seeds
Indoors- 4-5 weeks before last frost 1/4” deep with soil temperature at 65-75 degrees. After germination, grow in cool conditions 57-68 degrees for best results. Liquid fertilize seedlings every 7-10 days. Transplant out when there is little chance of frost.
Outdoors- Early spring until mid summer for fall crops. Plant 1/2 “deep and 18” apart.
Harvest- Tie up leaves around heads to blanch. Watch closely and pick before the curds begin to loosen.
Tips- A heavy feeder transplant/direct seed into rich, well composted soil and side dress when buds begin to form.
