Hi,
Further to enquiries in uk.d-i-y about protecting my softwood trough planters from the elements, as well as some special preserver in the end-grain at the base of the legs (see other thread) I'm thinking of giving them an all-over coat of Ronseal Garden Furniture Protector - see
Anyone know whether this sort of thing is likely to harm the plants that end up in the planters? It seems to be mainly white spirit and waxy stuff, although it does say that "the inclusion of a surface biocide also ensures that the coating is guarded from mould and algal growth".
I've got some heavy-duty-polythene liners to contain the compost, with holes in the bottom for drainage, so in fact the earth should not be in much contact with the wood, which will hopefully be better for both wood and earth.
Cheers!
Martin
