Chit Seed Potatoes (optional)
Stand seed potatoes eye-end up in egg boxes somewhere light and cool so they grow short, sturdy shoots.

Plant Seed potatoes
Plant seed potatoes 35 cm, rows 60 cm apart apart in rows.
- 14–28 days after “Plant Seed potatoes” · Early April – mid April
Look for Shoots
Green shoots should be showing. Keep weeds down — these crops hate competition.
