Growing Early potatoes in a pot

Water early potatoes regularly once the foliage emerges, aiming to keep the soil consistently moist but not waterlogged. In dry spells from late April through June, water deeply once or twice a week; inconsistent watering can lead to misshapen tubers or scab. Reduce watering as the foliage begins to yellow and die back, as tubers are nearly mature and excess moisture at this stage increases the risk of rot. Feed in April and May using a balanced general-purpose fertiliser or one higher in potassium to promote tuber development. Apply a granular feed when earthing up, or use a liquid tomato feed every two weeks once plants are established. Avoid high-nitrogen fertilisers, which encourage leafy growth at the expense of tubers. Early potatoes are not overwintered; they are a spring-planted, early-summer crop. Lift them as soon as the foliage dies back or when tubers are large enough to use—usually from late June onwards. Use a fork to dig carefully from the side of the ridge to avoid spearing the tubers. Eat earlies fresh; their thin skins mean they do not store well. Watch for potato blight, especially in warm, humid weather. This fungal disease spreads rapidly and can devastate a crop. Inspect plants regularly and remove affected foliage immediately. Slugs and wireworms can damage tubers underground; reduce slug populations with traps or barriers, and avoid planting in recently grassed areas where wireworm is common. Colorado beetle is a notifiable pest in the UK and must be reported if found. Mulch around plants with straw or compost to suppress weeds, conserve moisture, and keep soil temperatures stable.
