Can I make a big batch and use it diluted for the rest of the season, or should I do small batches in succession?

[noshed]

I usually make one binfull, stink the place out with it and then make another binfull...

I still have severall milk containers full from last year which I intend using this year... the trace elements can't have gone anywhere (?) so I'm presuming it's still as good

Me too, I'm going to use last years, just started the new batch
