Upon receiving the potato tubers, promptly unpack them and commence the chitting process. Place them in a seed tray or egg box, without compost, in a well-lit and cool area shielded from frost. Begin chitting approximately six weeks prior to your intended planting date.
Early cultivars can be planted and protected from harsh frost with horticultural fleece protection (typically from late February).
Dig a trench 8-13cm (3-5in) deep, adding a general-purpose fertiliser at the trench's bottom. Plant the potato tubers in the trenches, ensuring they are about 30cm (12in) apart, with shoots facing upward and being cautious not to damage them. Lightly cover them with soil.
Once the plants reach around 20cm (8in) in height, mound up the soil around the base, covering the lower two-thirds of the plant. Adequate watering enhances crop yield and prevents potato scab. Harvest from May to June. 'Sharpe's Express' bulks up slightly later than other first earlies but produces a heavier crop.
