Onions & green Onions

Onions

• If you wish to grow large onions, choose an intermediate type such as Candy, Red Candy Apple or Super Star. 
• Onion plants are often found in bundles.   Before planting, place the root ends in water to stimulate the planting.
• Transplants should be planted 1.5-2" deep and at least a hand width apart or approx 4" apart
• Onions have shallow root systems and need good, even moisture and adequate fertilizer to develop large bulbs.  We will discuss fertilizer in upcoming emails.
• Onions do not compete with weeds very well.  Keep the area weeded to reduce competition. 
• Onions have shallow root systems so water once per week if no rain. 
• Onions should be ready for harvest around the first half of July. 

Green Onions

• Use "sets" or what look like little onion bulbs to produce green onions, which take 30-45 days until harvest depending on the weather.
• Plant with pointed end up approx 1-2" deep, spaced about 1" or 2 finger widths apart.   My preferred method is to set the bulb in the soil with tops pointed up and then once all are planted, cover with compost until they are no longer seen. 
• Onions have shallow root systems and benefit from good even moisture from light watering a couple times a week.
