Episode Details

Propagation is your best friend as a plant parent. It's a free way to make more of the plants you already have, and watching new roots grow is so much fun! But there's more to it than sticking a pothos in a glass of water, not to mention that if you get the humidity wrong, you’ll get mold. So I invited over my go-to propagation nerd, Lindsay Sisti, to guide us through the different ways you can propagate successfully. She’s a propagation expert, plant breeder, and author of The Ultimate Guide to Houseplant Propagation. She’s been in the podcast before, and we've both survived mold cleanup in our own homes. Listen in!
