Hi I bought calicified seaweed to go in the growbags for the spuds but then someone said calcified seaweed is like lime and the potatoes dont like it and I need seaweed fertiliser....didnt know there were so many seaweed products lol.....so any help would be greatfully received, calcified seaweed good? what's the difference with seaweed fertiliser??...and some say 5 potatoes in a 40ltr bag some say 3...., so far I have 40 potatoes chitting and I'm going to have bags in the living room at this rate....phew who knew growing potatoes was soooo complicated

Samm, you should be OK with it if the compost in the bags is on the acidic side. Calcified seaweed is indeed like lime and it can cause scabbing on the potatoes. Some varieties are more susceptible than others so you won't know until you try. Scabbing is usually only superficial and doesn't affect the eating qualities of the spuds, it just makes them look a bit....scabby.

I put 3 maincrop or 4 earlies in a 40 litre bag.

Colin thankyou, I've put 4 earlies in a bag (and when I ran out of 'potato bags' I thought I'd trial one black thick plastic rubble sack, with drainage holes, and one white poly woven builders rubble sack) have put multipurpose compost and slow release potato fertilizer and a bit of pelleted chicken poo in plus a bit of vermiculite and a few water retaining gel crystals (I was told potatoes like to be pretty moist??) and they're out in a sheltered position round the front of the bay window outside til the temp picks up a bit at night, once they produce leaves I might move them to a more 'sunny' location?? does it sound right ot you??
