A few years ago in our back garden, there was one small area of isolated lawn about 5m x .8m which I converted into a flower bed. I filled it with lots of bulbs, some small roses and every year some bedding plants. It is much harder to keep than I thought and the weeds are terrible so have decided to change back to a lawn. Any tips on best way to go about this, thinking of digging it all up, digging the roses out individually, trying to pick any bulbs i can find, then spraying some weedkiller and then planting grass seed? Worried the weedkiller will affect grass seeds growth and is it getting late in the year to be putting grass seed down?
