For the first time, this year's onions from seed were spectacular -- uniformly big, beautiful and delicious.
We chose intermediate day varieties: Walla Walla (a large, sweet white) and Rossa di Milano (a large heart-shaped red), both from High Mowing Organic Seeds.
We started the seed indoors under lights on March 7th, then transplanted the seedlings into small six-packs three weeks later and planted them in the garden on May 2 (8 weeks after seeding).
The soil was well prepared with compost, manure and organic fertilizer, and the seedlings were planted on 6" centers. (We did not trim the seedlings, as recommended by High Mowing, to increase their size.)
The plants were kept well watered and weeded throughout the growing season, and side-dressed with sifted compost at least once during the summer.
Our first harvest was on July 25th (140 days after seeding, 112 days after planting). These onions have been providing a solid harvest for over a month.
We couldn't be more pleased!
