I have two RHS books for sale.
First one is the RHS Encyclopaedia of Plants and Flowers http://www.waterstones.com/waterstonesw ... s/6030522/
Seconed one is the RHS encyclopaedia of Gardening http://www.amazon.co.uk/RHS-Encyclopedi ... 1405322276
These books make a very expensive and comprehensive set that will give you guidance on so many aspects.
Rather rare and very expensive set originally.
Ideally I'd rather not post them, they are around 700 each book and being hardback they weigh a fair bit (however I will post if postage is covered).
New you'd be looking at around £60 for the pair however I'd happly let the set I have go for £25 (ovno) as I specialise more in trees and forestry now so I've had their use as such.
Any questions just ask.
Collection from manchester/oldham area would be great. thanks
