The season for organic potatoes in Britain is shorter than that for conventionally grown potatoes. The first organic new potatoes are dug in late April/early May and the first large, storable potatoes arrive in shops in September. The late arrival is due simply to the slower growth rate – conventional potatoes grow fast with the help of fertiliser and a lot of water. Using less water and allowing the potato to grow at a natural rate not only strengthens it, protecting it from disease, but it gives the potato more flavour. Here is an instance where there is no doubt at all that an organic food has more flavour than its conventional counterpart. Ordinary potatoes are routinely treated with anti-blight spray – their fast growth means weaker plants that need frequent treatment. They are also treated with sprout suppressants and insecticides after harvest. Organic farmers find that growing several types of potato throughout the season in soil that has been well nourished with manure will also help control disease, but they are allowed to spray with copper to prevent blight. Copper treatments are controversial, as residues remain in the soil, but still greatly preferable to the numerous chemical treatments used on conventional potato farms.
