They have travelled from the Andes in South America and have been around for a very long time, used as a food staple by Incas. But after taking a back seat to more prolific, faster growing commercial crops, heritage potatoes are making a come back.
Roger and Viola Blok of Purakaunui Heritage Potatoes know all about the high food value and anti-oxidant properties of these brightly coloured purple, red and pink tubers. If you are at one of the coastal markets (Seacliff, Portobello, Port Chalmers) where Roger sells his potatoes you’ll find he is happy to share his knowledge and experience. His stall signage is full of good information and he takes time to chat with customers. He’s as keen to educate as he is to sell fresh produce .
Freshness is assured as all potatoes for sale are washed and sold within 2 days of digging, any surplus used by family or discreetly dropped at various back door steps in his community. This interaction with customers is an important aspect of Roger’s business. Information is shared, contacts are made. These links, say the Bloks, form the basis of building and supporting communities.
Roger is happy to share his roadside stall on Purakaunui Rd. with neighbours as a co-operative arrangement. This serves everyone, local growers as well as passing neighbours and tourists.
When asked what growing methods he used Roger replied, ″Honest growing and the three S system ″. Honest growing includes traditional horticulture techniques taught him by his Dad, good work ethics learnt from his parents, Marie and Charles Blok, and his own common sense way of doing things. His background in both landscaping and engineering serves him well. Honest growing also means making use of what is available, recycling, and not using chemicals. The 3 S’s are sheep shit, stinging nettle and sweat. Often cursed, Roger can only say good things about stinging nettle and, after years of working with it, he is now oblivious to its sting. As well as being home to ladybugs and a hatchery for the red admiral butterfly, stinging nettle removes any residual phosphates from the soil. It also provides a natural water retention system by capturing evening dew and delivering moisture down to the soil. This is vital on Blok’s property as it relies solely on rain water. Plants are watered as seedlings but after that they are on their own and get watered only when it rains ! Crops are rotated and the soil is replenished using manures, seaweed, comfrey and mulch. 20 different varieties of potato can be in the ground at one time but not all will be for sale. Some are grown to build up stock supplies, some are part of a heritage potato seed bank and others may be in quarantine until they prove to be disease free. Roger and Viola also like to cook and taste new varieties before they sell them so they can advise customers from personal experience. All potatoes sold by Bloks can be used as seed potatoes. Their heritage potatoes aren’t washed in fungicides or sprout inhibitors as are many commercial varieties. Blok’s potatoes can be put in the sun to develop a sprout, a process called ″ chitting ″. Their heritage potato varieties include Urenika, Salad Blue, Maori Chief, Pink Fir .……..
Their produce has diversified over the last 3-4 years of selling at markets, local restuarants and shops. What started out as lettuce and potatoes now includes 3-4 types of onions, salad greens, mescluns, endives, Russian kale, 2-3 types of cabbage and collard greens. They are also becoming famous for their large Hosta collection. The Hostas will be for sale, along with potatoes, at the Lady Thorn Dell in Port Chalmers late in October.
Watch out also for gate sales from their roadside stall from mid November, daily but particulary weekends.
