Cold Stratifying Milkweed Seeds for Monarch Butterflies

Updated: Apr 6, 2023

Monarch Butterflies were declared an endangered species in 2022. Milkweed is the monarch's only host plant to lay eggs and the only plant that monarch caterpillars feed on. They're entire existence is dependent on US planting Milkweed in our yards and parks.



The good news for monarch enthusiasts is that common milkweed is a perennial plant that will return to your yard each spring, multiplying and spreading with each passing year.



However in order to germinate purchased milkweed seeds they'll need to go through a cold stratification process.


COLD STRATIFICATION:

the process of simulating a cold, damp winter to spur seeds into action for spring planting.


I use this method for many other seeds that require cold stratification like: mugwort, lavender.



You'll need:

milkweed seeds

paper towel

water

tweezers

storage baggies


Process:


  1. About 6 weeks before sowing, you'll use this method to cold stratify your milkweed seeds.

  2. Fold a paper towel four ways. Completely wet the paper towel and squeeze out so that it is damp but not drenched

  3. Open the flap on your paper towel and pour half a portion of your seed packet into the "pocket" of the paper towel

4) Use the tweezers to gently separate any seeds that are stuck together

5) Fold the flap back over and place the paper towel inside the storage baggie, release any air before sealing it closed

6) Label your storage baggies

7) Place inside your fridge for at least 6 weeks

8) Sow!


I hope this inspires you to grow milkweed, if not to raise your own monarchs, then to simply help the species thrive. If you have any questions about cold stratification, growing milkweed or raising monarch butterflies please feel free to get in contact with me: thelittlelovewitch@gmail.com
