Am new to gardening and would love your advice. Moved into a new house summer 2008. Front ‘lawn’ is about 30 x 30 so not particularly big. Have kept it grass, and want to stay grass for the forseeable. However, the soil is only about 3ft deep. Then it’s concrete/builders rubble. Planted some shrubs last year and they were all dead within two weeks. How best to prepare the ‘lawn’ for decent grass for this year? I have been sprinkling with moss peat for now and am about to put extra grass seed on top.
