Ok, in my quest for huge levels of amazing organic fruit and vegetables from the allotment, i’ve been doing some potato growing research. Various sources, including books, verbal and internet.
– Plant seed potatoes in rows 75cm apart for main crops and for 2nd earlies. 60 cms apart for 1st earlies.
– Place each potato 10-15 cms down into trench and up to 30cms apart within each row.
– Use a fertiliser directly around potatoes with lots of organic matter, including potash.
– Lightly cover potatoes then as each new shoot comes through. At a height of 15cms, cover with just 5 cms showing through. The bases of the plants must be covered to avoid scalding by sun which makes green areas on potatoes which taste bitter and contain a poisonous alkaloid.
– The new growth potatoes always develop above the height of the original seed potato.
– Cuts can be made and each seed potato can be divided up with each piece having a single bud. See images below for my latest plant experiment! : )
– If you want to store potatoes, leave them in ground for at least 2 weeks after plant has died back for the potatoes to develop thicker skins.
– Use straw or newspaper between layers of stored potatoes – keeping for 6-8 months.
