I have a nearly full packet of Growmore which has been in the potting shed over the winter and has now turned into a hard lump! Is it worth trying to break it up, will it be any use, or should I just dump it and buy a new one?
Looks like damp has got to it, I'm no chemist but I think the minerals would still be there. I wouldn't waste it.
Trying to be the person my dog thinks I am!
I'd put it in a strong sack or cover it with an old towel and whack it with a rolling pin.
In London. Keen but lazy.
west central Scotland
I think I'd do that too
. It'll still be viable, I would think, although maybe less effective.
No harm done in using it anyway, unless it changes in some way after getting damp. Wouldn't be much good as a plant food if that was the case though.
It's a place where beautiful isn't enough of a word....
OK thanks folks. I'll be out there whacking it tomorrow, lol
