A 1kg pack of a typical variety should contain over 10 tubers.

Plant First Earlies  10cm (4") deep,  30cm (12") apart in the row and 60-70cm (24-28") between rows.

Plant Second Earlies 10cm (4") deep, 30-40cm (12-16") apart in the row and 70-75cm (28-30") apart between rows.

Plant Maincrop varieties 10cm (4") deep, 40-45cm (16-18") apart in the row and 70-75cm (28-30") apart between rows.

Our seed potatoes are all certified and size graded which eliminates all over large and very small tubers although of course this does not mean that they are all identical as this can be dependant on the growing season and the variety.
