Space plants: 30 - 40 cm apart Compatible with (can grow beside): Peas, Beans, Brassicas, Sweetcorn, Broad Beans, Nasturtiums, Marigolds Avoid growing close to: Cucumber, Pumpkin, Sunflowers, Tomatoes, Rosemary Before planting expose seed potatoes to light to start shoots growing. Avoid direct sun as this can burn or par-cook the seed! Let the potatoes grow shoots up to 1cm long - this can take a few weeks. In hot or dry climates sprout seed potatoes in seed trays of dampened potting mix. Large seed tubers can be cut into pieces - just make sure each piece has at least one 'eye' or shoot. Let the cut pieces dry for a few days before planting or else they will probably start rotting. Green potatoes are poisonous! Potatoes accumulate cadmium and other heavy metals, so avoid fertilizers which contain these elements. Similarly, avoid using tyres as containers for growing potatoes as they can leach heavy metals.
