1) How frequently does soil require amendments? Do we need to aerate it every year? We are new to gardening and owning a home, and see that our backyard has wood chips (mulch?) on the surface. Do they need to be removed or replaced on a regular basis? 2) Our roses have many many bugs on the leaves as well as dark spots. After some searching looks like we have an aphid problem as well as the black spot disease. What should we do to keep our backyard free from harmful pests? 3) In general what will be the best way to keep pests away from vegetable gardens? |
