I don't know what the 4 in 1 dressing was, but presumably it was a chemical formula of some kind, and its always best to wait 6 weeks between dressings, particularly if they are granular in formulation.

Yes it is one of those Evergreen or something like that, and Westlands After-cut.

But, thank you verry much for your reply, I will take your advice, I see that on the 4-in-1 it only said ..'' a further application might be required ''.... so by that, and your comment, I deduce they would suggest no further aplications within the 6 weeks,

Thanks once again,

Well that's interesting - the boxes usually say repeat after 6 weeks to 2 months, but not past end July, or they used to...
