I need to fertilize my sales iris heavily, as we're on sand. I use a 10-10-10 and Miracle Gro often. My flower gardens get compost and fertilizer every couple of years. My veggie garden, I never fertilize. I use compost and mulch heavily with straw. Had no diseases at all on the tomatoes this year, with the straw, even though we had such wet and dry periods. Raspberries and asparagus get some 10-10-10, just too big an area for the amount of compost we produce.
