I have just taken one on too that is......well a bit of a disaster.........HUGE garden, (they have a ride on mower) and an inherited vegetable patch at the bottom of the garden the size of which would be fought over by many allotmenteers.
It has 2 beds, one running on the right hand side, and full of........well clay from when they put in the conserve, and dumped it on the I am sure once well established garden, and the other bamboo filled!
The only other real greenery are some huge hideous laurel hedges...................................BUT since I have been visiting they are getting a bit more enthused and there was even mention of taking down the laurel hedges to see to the back of the garden, so maybe there is hope for some! ;D ;D
(they also have a big apple tree, I got to pick up all the apples cos she didn't know what to do with them! :o )
