Difficult to understand the application. Whats the problem with grass and weeds near wood. The wood would have been better 'pressure treated' with presevertive if its in contact with the ground. If the wood is used as an edging then maybe lay some brick paving blocks between the wood and the grass/weeds.

As others have said, Jeyes is used as a path cleaner and outdoor disinfectant. Used for the right application its a good product. The stuff will burn leaves and plants though if it lands on them. It stinks too. When I disinfect my greenhouse with it I use a superspray hose end sprayer so I dont have to touch it. The stink stays around for quite qa while. For anyone wantingto use Jees to wash out their greenhouse I can recommend this sprayer. It dilutes as you spray so you dont contaminate a buckets and you can stay outside while you spray inside. It connects to a hosepipe like a miraclegrow but you can use anything with it. www.superspray.co.uk
