For summer-planted seed potatoes, skip the chitting process. Instead, directly plant them in well-prepared trenches, spacing them about 30cm (12in) apart. Alternatively, use a potato grow-bag with at least 20cm (8") of compost beneath the potatoes. Add a general-purpose fertiliser at the bottom of the trench or grow-bag, then cover the potatoes with a 20cm layer of soil or compost. Ensure they are well-watered. As 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. Protect the crop from frost, and expect harvesting in approximately 12 weeks.

For spring-planting seed potatoes: 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. For early varieties, you can plant them with frost fleece protection, while later varieties should be planted after the harshest frosts have passed in your region (typically mid-March to mid-April). Dig a trench 8-13cm (3-5") deep, adding a general-purpose fertiliser at the trench's bottom. Plant the potato tubers in the trenches, ensuring they are about 30cm (12") apart, with shoots facing upward and being cautious not to damage them. Lightly cover them with soil. Once the plants reach around 20cm (8") 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 in June - July.
