Q.Fertilizing Onions
I have already planted my onion sets. I have heard not to put fertilizer close to the onions. How should I fertilize and with what? Thank you.

Fertilizer while the sets are young can burn them. Give them a little time to establish and then you can fertilize with a slightly phosphorous heavy fertilizer. Before fertilizing, make sure the plants are well watered and try to fertilize on a cloudy day. This will reduce the risk of burning the plants.
