Well I Hope Not All Tops

Trying something New this year growing Potatoes in Bags.

As they was coming up I put soil over them.

They are well over the Bags and getting ready to Bloom.

My wife don't think they are going to make.

Different spuds have different haulm/shaw/foliage heights.
I tend to go by the THICKNESS of the stems as a guide to likely harvest & yours look decent.
Time to step up the liquid, & in pots I'd use a liquid feed like seaweed or comfrey tea, or tomato feed, as the extra water required might sluice out the nutrients.
