This is what my Kestrel potatoes were looking like last weekend (5th May), before I did some "earthing up"...
And after the earthing up (on the 6th May)...
They have been growing well all week and are now even further above the soil than last week!
And the ones growing in bags are doing pretty well too. In the bags, I've put a bottle with the bottom cut off so that I can water to the base more easily, although with all the rain we've had recently I haven't used the watering can in weeks!
