For the price the crop is very sparse, I have sowed these before and expected better. On the other hand the foliage is healthy for longer? Not worth the price

Nice plants always. A little pricey but you are paying for quality, which I much prefer.

The drought didn't help these. Great at first lifting esp good for baking, needing cooking slowly. Went flour quite soon as I couldn't spare water for them never usually have to water potatoes in Cheshire.

Very pleased with them! I probably left them in the ground too long but veg gardening is a hobby I have taken up this year, having just retired.

Potatoes grew really high and looked healthy but there were few potatoes when dug up despite me watering regularly. Think the low yield was more to do with the prolonged drought and baking temperatures than anything else. Would grow again though and hope for more favourable weather next year.

Yield wasn’t as large as other types I’ve had in previous years. They taste good but not like jersey royals, as advertised. Might try again next year though.

We grew these in tyres because on the whole potatos take up so much room in the vegetable plot. They did well and we had a heavy cro Perhaps next year I shall harvest them earlier as I let them grow toolarge.
