Gardeners prefer the ease and certainty of transplants because compared to growing bulb onions from seeds, they're far more productive and quite trouble-free. We grow ours over the winter in the deep South, so they get really husky by the time Spring comes in the North and are well-rooted and ready to spring into life. All our seedlings are disease and pest free, certified to enter California and Idaho. Sold in bundles, each containing approximately 50-60 plants depending on plant size. Our bunch will plant two 10' rows, provided they are spaced 4" apart. Be sure to tell us when you want yours to arrive.
