Steps to Grow Cabbage from a Head Scrap

Here's how to grow a new cabbage plant from a scrap of an existing head, based on the reference provided:

Get a cabbage scrap: Start by selecting a healthy cabbage head. Take a scrap from the base of the head.
Cut the scrap: Carefully cut the scrap from the cabbage head using a clean knife or sharp tool.
Place in water: Put the cabbage scrap's stem in shallow containers filled with water. The scrap should be partially submerged, with the cut end in the water.
Wait for roots: Allow time for the cabbage stem to develop roots. This process can take some days or even weeks.

The process, although simple, can be made clearer with some additional explanations:

Selection of scrap: Ensure the scrap taken from the cabbage head is at least a couple of inches in size and includes the bottom stem.
Water quality: Use fresh, clean water and change the water every couple of days to prevent bacterial growth and ensure proper oxygen supply.
Container: A shallow container like a small bowl or dish works best. The container should be wide enough to allow the scrap to sit comfortably.
Light and temperature: Place the container in an area that gets indirect sunlight and has a moderate temperature. This helps stimulate root development.
Patience: Root growth can vary, so be patient. Watch for small roots to start appearing from the stem.

Once you have a well-developed root system:

Planting: You can transplant the rooted scrap into soil in a pot or your garden.
Soil: Choose a well-draining, fertile soil for best results.
Care: Provide the young cabbage plant with regular water and appropriate light to continue growth.

This method will help you grow a new cabbage plant from the scrap of an older head.
