While starting seeds indoors always gave me satisfaction of seeing my baby plants magically transform each summer, there were definitely lots of growing pains along the way:

  • Bad seeds can put your garden way behind schedule (or force you to buy plant$)


  • Seedlings can get leggy unless you use anto promote stronger stems


  • Fragile seedlings can die inside


  • Fragile seedlings can die during outdoor transplanting


  • Seedlings can drown, bake, or get blown away


  • Did I mention our  rambunctious four-legged friends?…Oh Deer!

Starting Seeds VS Cuttings

While milkweed seeds can do the job, they just don’t measure up to cuttings…especially in the case of annual varieties (for most) like swan milkweed (Gomphocarpus fruticosus), and tropical milkweed (Asclepias curassavica).

After your first season starting milkweed seeds, you’ve basically won the ‘milkweed lotto’ for life if you take advantage of your mature plants…you won’t even have to pay taxes!

Tropical milkweed varieties are prime species for winter cuttings since they can be overwintered indoors. When trying to propagate native milkweed, it’s easier to take summer cuttings for outdoor fall planting.

Milkweed Cuttings Benefits

  • No pots, no soil, no mess if you keep the cuttings in water
  • Doesn’t require grow lights, window placement will suffice
  • Require minimal care compared to seeds
  • Cuttings will grow, flower, and seed much quicker than seedlings
  • Cuttings are strong, sturdy, and dependable for transplanting
  • Plant cuttings are the gift that keeps giving…100% free!

Tips to Grow from Cuttings (UPDATED AFTER VIDEO)

A Step by Step Tutorial for Growing Tropical Milkweed from Stem Cuttings. Growing milkweed has never been so easy...and so fast!


  • Root overwintering plants anytime between January and March. Start to grow from cuttings at least one month before planting outside


  • Fill cuttings containers (I use 20oz clear plastic cups) with distilled water (not tap water) because it has a neutral PH level and no additives or elements that could potentially harm developing plants


  • Place plastic wrap over each cup and secure it with a rubber band


  • Use gloves or wash hands thoroughly after handling milkweed to avoid getting milkweed sap in your eyes later. This can cause burning and a few unfortunate souls have even had to go to the emergency room for treatment.


  • Make sure you only take milkweed cuttings from your healthiest plants


  • Take cuttings under water or rinse cut area afterwards to insure water uptake


  • Use a hand pruner or scissors


  • Cut at an angle just below a leaf node (while this is not as important for tropical milkweed, it’s a good habit to get into for taking cuttings in general)


  • Your stem cutting should be roughly 4″ long or 3-5 leaf nodes. You can take multiple cuttings from the same stem.


  • Pinch off all foliage (except the top two leaves). Leaves submerged in water can cause bacteria and give off an unpleasant odor


  • Rinse off each cutting thoroughly with water to remove potential OE spores


  • Pierce the plastic with a small phillips-head screwdriver and then put each cutting through the plastic, except for the top stem and leaves. The cuttings should not be touching the bottom of the glass


  • Using a cloning machine? We replaced our foam inserts with rockwool cubes because the foam was causing the cuttings to rot at the insertion point. We still use foam to cover the holes where there aren’t any cuttings.


  • Place cuttings in an area away from direct sunlight, but receiving some light. Ours are on a table where they get a couple hours of dappled sunlight every afternoon. This has worked well for root growth.


  • Change cutting water and rinse out container every week to avoid fungus and disease



  • Fall cuttings give you a huge head start and more cuttings to choose from (however, you’ll have to pot the plants indoors after a couple months to prevent rotting)


  • If stems start rotting transplant into potting soil immediately and place by a window that gets (at least) two hours of sunlight per day. For more rigorous growth, place under grow lights or increase sun exposure

A Cloning Bucket can also be used to start milkweed stem cuttings and other butterfly plants. Clone bucket systems will grow roots faster than just submerging cuttings in a glass of water.

So, a few months after starting tropical milkweed from cuttings, what can you expect??
