Should I cut the top off my 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).
Will onions keep growing if you cut the tops off?
If an onion's stem is broken off, new green growth will form, and the onion will continue to grow. Be careful, however, to avoid breaking the stems late in the growing season as they are important for bulb growth.
Should you trim the tops of onion seedlings?
Why are my onions leaning?
So, why are your onions falling over and drooping? Onion leaves fall over when the plant is mature and the bulb is ready for harvest. This happens after the leaves have sent their energy to the bulb to make it grow bigger. Lack of water, pests, and diseases could also cause onion leaves to fall over.
Should you stake onions?
Decide how many rows you need to accommodate the number of onions you want to plant. You'll want to allow for about 4-6 inches between seedlings, and 12-18 inches between rows. Put a stake in the ground at either end of where you plan to place each row.
