Stop flushing cash down your drain

We’ve just been put on a water meter and I’m worried about my garden drying out. – Mrs M Shaw, Dunstable, Beds DAVID: Install a water butt from your downpipes to get plenty of free rainwater. If you are using a hosepipe, water after dark to minimise evaporation and lay bark chips over beds to stop them drying out. Recycle bath water on to containers and pots, when it has cooled.
