Had my garden done over with areas of wood chip a while ago
(www.marshal.co.uk/garden.htm if you're really board!). In some areas
the wood has now rotted down to the point where things are begining to
grow in it - not the idea at all (

So, what sort of rolling program of maintainance do I need for this -
clearly I have to replace some of it - I started trying to seive out
the soil that's formed but that will take for ever. If the only option
is to replace the lot (which I'd rather avoid) are there ways of
treating it so it lasts longer?

TIA
