Propagation Tips For Plant Parents That Actually Work: Prop Boxes, Ikea Grow Cabinets and How to Avoid Mold Damage

Author: Maria Failla- Happy Plant Lady and Author of Growing Joy: The Plant Lover's Guide to Cultivating Happiness July 28, 2026 Duration: 1:14:40

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!

There’s a quiet, accessible kind of wellness waiting for you on a windowsill or in a patch of soil. Growing Joy with Plants explores that very idea, moving beyond basic tips to examine how our relationship with the natural world directly nurtures our mental and emotional health. Hosted by Maria Failla, a self-proclaimed Happy Plant Lady and author of "Growing Joy: The Plant Lover's Guide to Cultivating Happiness," this podcast feels like a warm conversation with a knowledgeable friend. Maria guides you through the practicalities of keeping your houseplants alive and thriving, but the discussion always circles back to the deeper connection-how the simple acts of watering, repotting, or simply observing growth can become anchors of calm in a hectic day. Each episode digs into how gardening and engaging with nature, even in small urban spaces, offer tangible tools to manage feelings of anxiety and overwhelm. This isn't about achieving a perfect indoor jungle; it's about finding moments of peace and genuine happiness through the process of care. The underlying message throughout the podcast is a powerful and gentle reminder: tending to your plants is fundamentally an act of tending to yourself. You’ll come away with not just better plant care knowledge, but a refreshed perspective on cultivating joy in your daily routine, learning that the serenity you might seek on vacation can be rooted right in your own home.
