Stonecrop (Sedum) is one of those easy-going plants that usually doesn’t ask for much. But if it gets hit by a fungal infection like gray mold (Botrytis), it’s going to need a little extra TLC from you. Luckily, there are some simple, natural ways to kick this pesky fungus to the curb and get your plant back on track.
How do you get rid of gray mold on Stonecrop?
To fight off gray mold, you can use a natural fermented nettle or horsetail tea. Just spray your homemade solution directly onto the plant and repeat the process until the fungus is completely gone. Make sure to prune away any infected parts of the plant and toss them in the trash—don’t compost them, or you might spread the spores!
What does gray mold look like on Stonecrop?
You’ll first notice gray mold when the leaves start turning a funky brown color. If it goes unnoticed for too long, a fuzzy white or gray fungal “carpet” will start growing on the plant. If you see that fuzz, it’s time to jump into action to save your plant and step up your Stonecrop care routine. Gray mold is a tough fungus that spreads like wildfire; it won’t just go away on its own. Be thorough and gentle when cleaning it up to make sure you get every last bit.
Why does gray mold grow on Stonecrop in the first place?
If your Stonecrop is showing signs of mold, there are usually a few culprits. Most of the time, it comes down to watering habits or nutrient issues. You want to fertilize your Stonecrop regularly with a gentle, plant-friendly food. Watering is also key—overwatering leads to soggy soil (standing water), which is a recipe for disaster. Keeping the roots from sitting in water is the best way to keep your plant healthy and mold-free.
How can you prevent gray mold on Stonecrop?
The best way to keep Stonecrop diseases like gray mold at bay is consistent care. Even though hardy Stonecrop varieties are tough as nails, they still need a check-up now and then. Keep an eye on your plants, and be sure to snip off any brown or dead stems. Proper watering and feeding are your best defense against fungal infections.
Pro Tip: Fertilize to keep the mold away!
To protect your Stonecrop from pests and fungi, it needs a steady supply of minerals and nutrients. Since gray mold is so stubborn, prevention is your best friend. You don’t even need fancy store-bought chemicals—natural fertilizers from your kitchen work great! Try mixing some coffee grounds, cooled vegetable cooking water, banana peels, or horn meal into the soil to give your plants a healthy boost.
