Our onions have beautiful tops but the size of the bulb is about the same as when we planted them. I read here that depth of planting appears to be critical and we may have planted too deep but we followed instructions on the package - we used onion sets, red and yellow. It appears we may need more nitrogen but are there any other options for us with fall coming in the not too distant future to increase the size of the onion bulb. We're in region 5. Suggestions would be appreciated. In advance, thanks for your assistance.
