As you know this year for the first time we have grown onions from seeds. They were planted inside under lights and finished off in the cold frame. Then they were planted in the garden beside the row of bought onions that were planted two weeks earlier. Interesting to see how they compare. The bought onion sets are not nearly as healthy looking as the ones started at home. The only thing I would do different is maybe plant them a little earlier next year. However we shall wait to see what harvest brings.
We have 2 rows of bought onion sets. 2 rows of onion from seeds and 1 row of green onion from seeds.
