I have a vegetable garden and nothing seems to be growing right, especially the cucumbers. They grow very slow. I have used blood and bone meal. It doesn't seem to be doing anything, maybe cause it's a slow release one. Not sure which fertilizer to use and how much to use. If you can help, that will be great.
