Project Bak Choy: grow new leaves from scraps
This post is long overdue. I am starting on a second round of reviving bak choy. So I hope you enjoy this. Step 1 Buy some healthy looking bak choy from a (Chinese) supermarket. Lop off the leaves about 1½ inches from the bottom. Immerse in little containers like these. If it's terribly cold, I use water that is just warm to the touch. Put them on a window sill or somewhere with lots of light. And warmth where possible. In the picture above, you can see bak choy in different stages of regeneration. The green leaves traps energy from the sun and soon you will find roots, or root nodules, at the bottom of the stumps. Be patient. It may take more than a week to root. Meanwhile, refresh the water at least once every two days. You will find some bits getting sodden and looking like it's 'rotting'. Remove those bits, clean up the plants under running water and return them to the containers with fresh water. Step 2 When the roots are visible and clearly thriving
