I agree lack of drainage holes probably the main problem!

They are in these laundry tub things with handles and I forgot to add holes.

Added them now and put a full gallons through to hopefully leach it out

If something has been overfertilised in a container.

Does anyone know if putting a lot of water through it would be enough to dilute the problem?

Before drowning them, maybe try furtling to check for potatoes ... 

they were planted in february.

Variety Swift

Swift potatoes are known as the earliest cropper on the market. They can be lifted as soon as just 7 weeks from the time of planting

Cant seem to load the link...

Would there not have to be flowers first?

[mumofstig]

There aren't always flowers.

[DD.]

Link works fine here.

Got the link to work in the end. Was my work PC playing about.

I'll have a furtle tonight and maybe even pour out a batch.

It has been 13 weeks after all and I'll post the results.

So , I had a furtle and found a golf ball sized potato near the top, so thought! I'm tipping them out.....

Look at these babies!!

It's the 1st of May. And I have a bumper crop of large new (swift) potatoes!!!

Thanks BabbyAnn, your a genius

If anything, they're a little big

[BabbyAnn]

wow - I started to suspect the "natural" die back once I'd figured the variety was Swift, but your little harvest is even better than expected.  Well done you - enjoy
