I am new to potato growing and this year have planted 20 first earlies (10 each of Kestrel and Winston) and 20 maincrops (Golden Wonder). All the first earlies are growing merrily and have been earthed up twice.
But only some of the maincrops are growing - approx 12 out of 20. The rest are nowhere to be seen. Is it possible I received 8 duds in the original bag? Everyone else's potatoes on the allotment seem to be growing perfectly well, with no gaps in the rows. All potatoes were succesfully chitted prior to planting out (bar two, which were planted anyway).
Can anyone help?
