Container vegetable gardening can be a challenge come mid August. This is how I use Epsom Salt and chemical fertilizers to feed container vegetables. You can substitute fish emulsion or other organic water soluble fertilizers if you wish. I explain why I use these products in mid August. My goal is to get the container soil filled with what the plants needs so the can make it into late September.
