Can I plant onion in May?

How far apart do you plant onions?
Plant sets in early spring as soon as the ground can be worked. Sets should be planted at a depth of 1 to 1 1/2 inches in rows 12 to 15 inches apart. For dry onions, plant the sets 2 to 3 inches apart. Sets grown for green onions can be planted closer together.
Can onions be left in the ground over winter?

The onion that is left in the ground will begin to form sections, much like a garlic clove. Those sections can then be separated and planted as sets each spring.
Can I plant onions in January?

Can you cut onion tops while growing?
Whether you’re growing onions from seed or have purchased already-developed onion sets, trimming the onion stem during growth can help promote stronger plants and bulbs. To ensure a successful harvest, most growers recommend using onion sets, which are much faster and simpler for the home gardener.
When should onions be harvested?
There is no perfect size, just pull when they are big enough to suit you. For full-sized bulbs, let onions grow and mature.
