How do you propagate green spire Euonymus?

Cut a 2-inch vertical cutting from the stem of your plant with sharp, clean shears. Prune off any leaves that are below where you will put it in the potting mix to avoid creating an air pocket which might rot and kill your new rootstock. Stick them upright into moist potting soil so they’re at least half buried – this is important as roots need oxygen too! Firm down around their base gently then water well afterwards for good measure before putting back on display or giving away again.

Stick the cuttings upright into growing medium so that they are barely touching soil. Water them well and cover with dirt to provide a stable foundation for their roots as soon as possible. Green euonymus cuttings root best when temperatures stay between 75 and 80 degrees Fahrenheit, but anything over 68 will keep them alive in order to grow more quickly.
