Water Rat

I don't......I usually fertilize and rototill right before I plant the vegetables in the spring. If you can get your hands on some pure chicken manure....get it. It's much better than cow manure. But make sure you rototill your garden 6-9 months ahead of time because it will burn the roots and/or kill the plants. Or you can just buy the granular fertilizer and mix it in the soil in the spring.
