Dahlia blossoms will make yellow, orange and green dye colours. They can be picked fresh, dried or after the first frost.


Difficulty Level:


Time Required:

1 day

Here’s How:


  1. Pick the blossoms and soak in water overnight.
  2. Fill the dyepot with water, add the dahlias and simmer for about an hour.
    For stronger colour simmer for another hour.
  3. Add clean premordanted wool to the dyepot and simmer for an hour or until sufficient colour is reached.
  4. Allow the dyepot to cool before removing the dyed wool.
  5. Remove the wool from the dyepot, rinse and let dry.


  • You can strain the blossoms from the dyepot before adding the wool, or put the blossoms into a nylon stocking before placing them in the dyepot.
  • Try alum, tin, iron or baking soda mordants to obtain different colours.
