Put Seed Potatoes in Egg Cartons for Sprouting Sprout (“chit”) potatoes before planting. In early spring, place seed potatoes in egg boxes, with the end with the most eyes facing upward, and set them on a cool windowsill. Plant when the shoots are ¾in (2cm) long.
STEP 2: Plant Potatoes In Large Plastic Bin
Potato Planting in Large Plastic Bin From mid- to late spring, make drainage holes in the base of the bin and fill a third with compost. Evenly space five potatoes on the surface, with their shoots pointing up. Cover with 6in (15cm) of compost and water well.
STEP 3: Earth Up Potato Plants As They Grow
Earthing Up Potato Plants as They Grow Add compost around the plants in stages as they grow until the bin is full. Known as “earthing-up,” this encourages more tubers to form, prevents them turning green and poisonous on exposure to light, and reduces frost damage.
