Beginner Gardening: growing onion bulbs, 0 by Farmerdill

You guys need to learn the difference between sets and plants. Sets are always long day storage onions and are usually used for spring onions as they definitely tend to bolt. Rarely will bulb in any area where temps in June climb toward triple digits. They need the summer solstice daylight length to begin bulbing and they can't stand the heat. South of I20 in Georgia we grow short day onions in the winter. Plant in October for harvest in April. An onion "bulb" is actually a cluster of modified leaves. They require a lot of nitrogen so you might want to add a nitrogen source to your compost. Dixondale is a good source of plants and their planting instructions are good. Mixing additives into soil is good, they say put between the rows, because some folks will put in the row and then transplant directly into the fertilizer. If it is very strong that will stunt or destroy the plants. Between the rows is safe and encourages the plant to grow a larger root system.
