I bought loads of cheap MP compost (Levington's Essentials ) which was crap but I roughly mixed it with composted horse/farm manure (Wickes) plus a handful of 6X chicken fertilizer .
Chitted tubers on a 6" base of this then cover and earth up as the halms grow.
I never let the tubs dry out so possibly too moist for ants ?
There is a bit of a trial going on with these 8 tubs - 4 had Vitax Potato fertilizer mixed in and the other 4 had blood ,fish & bone mixed in but I doubt I'll see any significant difference.
