Alright i'm going to do some yardwork for her and measure out the dimensions and check the sunlight this week. As for compost i've never done it so I've got questions so sorry. I've been reading it can give you legionnaires disease and that you can also get it from potting soil? So how far should the compost pile be from the garden and the house. I worry about diseases i'm one of those people. My mom is a smoker with asthma so I'd like to be very careful.
