No need to start the greenhouse early to start your onions. Save the heating and labor costs and get a jump on weeds and an earlier harvest with Johnny's quality onion plants. These pre-grown, spring-dug plants arrive as dormant starts–expect them to be dry and/or pale in color due to dormancy and shipping. They are very hardy and will thrive if cared for properly. The best crops are grown in humus-rich sands, light loams, or other soils high in organic matter.
