Always using different methods every time is more of a motivational challenge than using the same ones. A manager should get to know their employees and figure out which employees like what and what kind of position the employee is in first off before a manager starts using methods on an employee.
Preparing the Soil. Soil is best prepared for planting onions by mixing in 1 1/2 inches of compost or by adding 10-20-10 fertilizer in a trench. Dig the trench 4 inches deep, add 1/2 cup of fertilizer for each 10 feet of row, cover with 2 inches of soil and plant your onion sets on top of that.ou can grow onions in U.S. Department of Agriculture plant hardiness zones 3 through 9. Onions are a cool-season crop. If you live in a Mediterranean climate, it's best to plant what are called short day bulbs in the fall. They will only harmed if temperatures drop below 20 degrees Fahrenheit.
Outdoors, sow seeds thickly in rows about 1/2 inch deep. You can try mixing in radish seeds both to mark the planted rows and as a trap crop to lure root maggots away from the onions. Thin seedlings to 1 inch apart, and thin again in four weeks to 6 inches apart. For transplants or sets, use a dibble to make planting holes 2 inches deep and 4 to 6 inches apart. Use the closer spacing if you plan to harvest some young plants as green onions. For sets, open a furrow 2 inches deep and place the sets stem (pointed) end up 4 to 6 inches apart, and then fill in the furrow.
