I'm hoping I haven't made mistake number 3!!! My potatoes weren't growing well and after a few days of rain have shot up, I have a feeling I should have done something with compost before they got this big??
I have looked on the big web and there isn't really much info after the initial planting, and can't find much on the forum either about putting more soil on. Should I have done it already and if so, have I ruined them? If not then when should I do it? Also how much, do I completely cover them, half cover them or what??
Both varieties are earlys, first and second.
