My front lawn is now (thanks to landscaping) small at 1600 square feet. Due to trees the lawn is shady 50-60% of the time but I am removing a tree and trimming another to remedy this. The lawn is green, mostly weed free, but a bit thin and in my opinion in need of topdressing and over-seed. I wish to add 1/2 inch of top dressing but am not sure what to use. I do not have a machine that will spread the top dressing just have a wheel barrow, shovel and my back. I calculate that I will need 2.5 yards of topdressing but will likely get 3 yards to even up low areas. I understand that some recommend a mixture of loam, sand and peat while others use compost. Does anyone have any advice for this situation? I would like to get this done 1 day next week and plan on core aerating the day before.
