I planted “early potatoes” in a potato barrell in late March. Looked after it, watered it etc. I have a lot of foliage but only one flower. Is this OK? Have not grown them before so am unsure if they are flourishing. Should I give them tomato feed? How often should they be watered? I am not sure when they will be mature enough to harvest.
If they turn out to be very ‘soapy’ and immature, leave them for a couple of weeks for some starch to accumulate in the tubers.
