Sow your beetroot seeds either under cloches in February or unprotected from April to June. The previous autumn, dig over the soil well, removing stones - frost over the winter will also break up the soil further. Before seeding, weed the site thoroughly and dig it over once more, before levelling it off and raking over. Rake in a spread of general granular fertiliser around two or three weeks before seeding. Using the end of a cane or similar stick, create a trench with a depth of 2 cm.
Place two seeds next to each other, at a distance of 10 cm between pairs, and water in. Thin out the seedlings once they are established, with a height of around 2 cm, thin out the weaker seedling in each pair. To grow in succession, plant out a new row every 4 weeks.
To grow your beetroot in a container, loosely fill a pot with a diameter of 20 cm and a depth of 25 cm with multi-purpose compost. Sow the seeds in a thin scattering across the surface, then cover with a further 2 cm layer of compost. Once established, thin out the seedlings to leave a 10 cm gap between plants.
