Northern gardeners (Zones 3–6):
If you want big onion bulbs, plant long-day onions.
They bulb with 14–16 hours of daylight.
Short-day onions grow tall tops, but won’t form full bulbs this far north.

Too much nitrogen = big leaves, small onions! If your soil is rich in nitrogen, interplant onions with leafy greens like lettuce to help absorb the excess. This keeps your onions focused on bulb growth rather than foliage. A simple trick for better harvests! #GardeningTips #OnionGrowing
