I had my brick driveway fully powerwashed and resanded and weeds are already coming back just a few weeks later, there's not a lot that can be done, buy a big container of weedkiller and have a spare knife handy....
I've been thinking for a while that I might need to move, somewhere with a less high maintenance garden and nearer to my friends. I might sacrifice the bike and the garage to keep it in to get somewhere with a bigger spare room and simpler garden.
However, the idea of going through the house buying thing again is a bit daunting to say the least, and now it'll be coupled with selling one too.
