Garden with an STP...help!
last year we moved to rural Norfolk and into a new build. Our small 30'x20' rectangular garden is all lawn with two little trees planted one either side of the plot. Half the lawn (and the bit that we look out onto from our living room) covers a sewage treatment plant (STP) and there are two large and two small manhole covers dotted about for easy and obvious access.
I'd like to do something with the garden, initially plant shrubs to hide the fencing and alter the layout but I'm concerned about roots damaging the STP. Has anyone experience and advice please? Would it be wise to stick to pots and tubs and avoid planting directly into the garden?
