One of the last gardens I worked in just before packing up for winter is mainly made up of lawn and I'm afraid I know very little about lawns, not having one of my own. I'm hoping that our practical course at college gives us more tips on what to do with them as I imagine I will get asked about this LOTS if I'm going to be doing this as a business.
While giving this lawn a haircut, I had the good fortune to be working in bright sunshine - although perishing cold! - and was rather taken with this tree which I believe is a Sorbus acauparia - sadly not in my client's garden, but just outside his boundary fence. Stunning though.
