Grow maincrop potatoes for a larger yield that stores well through winter. Plant in spring and leave in the ground until autumn.
1 Chit Seed Potatoes
Place seed potatoes eyes-up in egg boxes in a cool, light place from 10th March - 24th March. This encourages sturdy shoots over 4–6 weeks before planting.
2 Plant Outdoors
Plant chitted potatoes in trenches or containers from 7th April - 5th May. Space them apart and cover with of soil. They can tolerate a light frost once established.
3 Earth Up
Draw soil up around the stems as they grow from 12th May - 14th July. This prevents tubers turning green and toxic. Build the mound to about high over several weeks.
4 Water and Feed
Water regularly to keep the soil moist, especially during dry spells from 26th May - 4th August. Apply a high-potash feed every 21 days to encourage tuber development.
5 Harvest Maincrop
Harvest from 19th August - 15th October after the foliage has completely died back. Leave the tubers in the ground for a few weeks after this to set the skins for storage. Lift carefully with a fork and store in a cool, dark place.
Companion Plants
Plants that grow well (or poorly) with Potato
Plants to Avoid
Pumpkin
Pumpkins have vigorous growth that can smother potato plants and compete for space and nutrients.
Squash
Squash plants spread widely and can overshadow potatoes, reducing their sunlight and growth.
Tomato
Tomatoes and potatoes are both susceptible to blight and can spread the disease to each other.
Why Companion Planting Matters
Companion planting can help deter pests, improve pollination, enhance growth, and maximize garden space. Some plants release chemicals that repel pests or attract beneficial insects, while others can improve soil quality or provide shade for sensitive plants.
