Couldn’t wait any longer. The polytunnel has kept the soil dry. The seed
potatoes have strong, stubby, green chits. So, I planted 6 Sharpes
Express & 6 Maris Bard today. I figured that if they do get caught by a
cold frost, I have still got some more chitting on the window-sill.
* planting depth 10cm

making shallow trench
* cover the potato with soil

cover seed potato
* planting distance in row 30cm

space potatoes in row
* distance between rows 60cm

potato rows 60 cm apart
Early potatoes are planted closer together than main crop, because we
harvest them when they are smaller.
Early potatoes should be ready for digging in 10-12 weeks!!
