Mulch or top soil ??
I am looking for some advice. I am wanting to improve my soil for next year. I live in a new build property and the soil is not great. I am growing mostly perenials with some annuals. What is best to add to improve the soil as some areas the soil is full of builders sand and does not retain moisture. Should I mulch my borders or add to top soil. also where is the best place to buy from?
