Why are my onions not growing

Onions are cool-season crops that require 90 days or more to reach maturity. Because of this long growing season requirement and their preference for cooler weather, planting onion seeds directly into the garden in the spring makes it difficult for the bulbs to reach a good size before warm temperatures arrive.

Why won't my onions get bigger?

If onions are planted too close to one another they will compete with one another, resulting in smaller bulbs. Whether direct seeding, transplanting seedlings or planting onion sets, onions should be spaced 3-4 inches apart to maximize growth.

How do I get my onions to grow bigger?

Plant the pots in the garden in early spring, and as they absorb moisture from the soil, they will eventually decompose, encouraging a secondary root system near the soil surface, which will produce larger onions. Onion sets and onion plants require loose soil and should be planted early (end of February or March).

What is the secret to growing onions?

Grow them in a sunny spot that has fertile, well-drained soil with a pH of 6.0 to 6.8. Improve your native soil by mixing in several inches of aged compost or other rich organic matter. Onions aren't great at taking up water, so it's important to keep soil moist so their shallow roots can drink up.

Do onions need a lot of water to grow?

What happens if you plant your onions too deep?

Don't Plant Too Deep! If you've planted the onions too deep, you may not be able to tell when the bulbing process begins as the onion is too deep in the ground. You'll end up with smaller bulbs shaped similar to torpedos because the soil will restrict the plants from bulbing properly.

When should we stop watering onions?

Trimming while seedlings are young is better for root and bulb formation. Cutting off the top green growth forces more of the plant's energy into the root system and also the forming bulb just above it (onions bulbs are actually the base of the leaf system with roots growing from the base of the bulb).

Sometimes onions will start to flower before the stem turns brown. If this happens, then pull that one and use it right away because they won't store well. You should not let them flower because that will steal all the energy from the bulb, making it super small. Which means there won't be much left for you to eat.
