Potato problem

Can't identify that mould? Got a great tip for keeping slugs at bay? Suggestions for organic weed control? Post them here...

Am growing potatoes in sacks this year. Have just harvested a bag of Swift - the spuds look v good and am happy with the yield. However, we found one with a hole in it, and the potato was all rotten on the inside. Am a little mystified as the seed were planted in new compost, and the bag has been standing on gravel, so slugs have not been a problem.

Hello Ken
Is this the remains of one of the original seed potatoes that you planted which often finish up like this. Its quite natural - don't know about the hole though.

Thanks, John, but I don't tink so. The original seed potatoes had gone all soft; this one was nice and firm on the outside.

...and more bad news. My wife has just found three more potatoes with the same problem. They are firm on the outside, but the centre is hollowed out and a bit messy. Couldn't see an bugs or slugs with the naked eye, however.

Just taken a look at 'The New Vegetable Grower's Handbook' by Arthur J. Simons, which ironically is quite old - 1st published by Penguin in 1945. He mentions one or two physiological problems with potatoes, including one called 'hollow heart' which can happen with some varieties when a dry spell is followed by heavy rain. Given that the potatoes were grown in a bag, it is quite possible I didn't achieve even watering. Do you think this could be the problem, from the symptoms I've described? Never heard of it before but then I've never grown potatoes this way before, either.

Evening Ken,
In Dr.Hessayon's "Vegetable Expert"book there is an illustration of a problem called "Hollow Heart" which is exactly as you describe.It is caused by a prolonged wet spell after dry weather and may rot when stored,and there is no cure for it other than watering during dry spells.

That looks like it alright. Many thanks, Alan & Snooky. In my defence, I'd point out that one day in early June we had more rain than in March, April and May combined. But next year I'll have to watch the watering more carefully. Or grow a different variety. We harvested Charlotte about a week earlier, and as far as we have seen so far, it hasn't suffered from this...
