I have had to do lots of lawn weeding lately so I sympathise I have plenty of bald patches at the moment. But yours isn't looking too bad from what I can see?
@tinley23 it's just a little builder's filling trowel - if you get one I recommend a bright handle - I had a better all metal double-ended one with a chisel blade, but I lost it somewhere in the garden and haven't seen it since!
@seacreature I have some very parched bits, and some really tough broad-leaved-grass which leaves gaps when I take it out, as does the self-heal and the violets - but I'm ever optimistic!
