"While it’s easy to find high-quality potting mix at gardening stores and nurseries, there are good reasons to consider #DIY #PottingMix. Making your own blend gives you greater control and allows you to make adjustments for different needs. You can also save money this way.

"As you investigate recipes for the perfect potting mix, consider the importance of leaving out peat. Peat moss is often used in potting blends but unfortunately it must be harvested from wetlands. The process damages a delicate ecosystem and releases carbon dioxide. Luckily, if you want to make soilless growing mediums, there are plenty of good alternatives. Here we show you how to make your own potting mix."

I hadn't considered using #RiceHulls in a #PottingSoil mix. But I am definitely going to incorporate that into a #PeatFree mix, along with #CoconutCoir, #Perlite or #Vermiculite, and aged #Compost!

#SphagnumMoss vs #PeatMoss: Environmental Guide 2026

Excerpts: "Here’s what shocked me: peat moss takes thousands of years to form, yet we’re harvesting it faster than nature can replace it. Meanwhile, sphagnum moss can be sustainably harvested in just 5-6 years. That’s a massive difference that directly impacts our planet’s carbon storage and wetland ecosystems."

[...]

"The environmental implications of choosing between sphagnum moss and peat moss extend far beyond your garden. Peatlands cover only 3% of Earth’s land surface but store twice as much carbon as all the world’s forests combined. When we harvest peat moss, we’re not just removing a growing medium – we’re releasing carbon that’s been locked away for millennia.

Research from wetland ecologists cited by Oregon State University Extension confirms that peat is being harvested at non-sustainable rates. The extraction process requires draining bogs, which immediately begins releasing CO2 as the peat oxidizes. A single hectare of drained peatland can emit 15-20 tons of CO2 annually – equivalent to driving a car around 50,000 miles."

"Sphagnum moss works exceptionally well for #orchids, particularly epiphytic species that naturally grow on trees. Its chunky texture provides the perfect balance of moisture retention and air circulation that orchid roots require. I’ve found that wrapping orchid roots in slightly damp sphagnum moss can revive stressed plants remarkably quickly.

For propagation, sphagnum moss creates an ideal environment for rooting cuttings. Its natural antibacterial properties help prevent rot while maintaining consistent moisture. Air layering, a propagation technique for woody plants, relies almost exclusively on sphagnum moss to encourage root development on branches still attached to the parent plant.

Carnivorous plants, which evolved in nutrient-poor bog environments, thrive in pure sphagnum moss. The moss provides the acidic, nutrient-free medium these specialized plants need while preventing mineral buildup that could damage their sensitive roots."
