If so what kind? The only outdoor store around me is Lowes, can i pick up all the supplies i need to refurbish my landscaping there?
Apply Glyophosphate (Trade name is Roundup) to the visible grass/weeds in the bed. If you feel frisky, add Preen before mulching to help prevent weed germination over the summer. DO NOT use fertilizer when mulching. All you will do is fertilize the weeds and encourage weed growth. I recommend staying away from the box stores (Lowes, Home Depot) because their products are generally cheap quality with an expensive price. Example- Roundup at Lowes is about 9% gly and the rest water. Commercial Roundup is roughly 40%gly for the same price (if not cheaper) at a landscape supply store.
