What’s happening to my #Sedum ?
Hey, guys! My sedum has this nasty white/brown stuff on it. I thought it was just dirt at first, but it’s spread across pretty much all the leaves now. To me it looks like some sort of fungus, but I’m not sure. Does anyone know what’s happening, and if so, how do I fix it?

Hi Jack, it's me again.
You know how on the other post you commented about using fertilizer high in nitrogen?
Unfortunately, high nitrogen and an unbalanced fertilizer makes the perfect environment for powdery mildew to grow and multiply rapidly.
Im going to suggest Insecticidal Soap. I use Bronners Castile Soap. It's plant safe and will not harm your plant.
While peroxide can be effective at killing it, it is quite harsh on plant leaves and it may damage them.
Here is what I would do:
1. Cut off all infected leaves because the spores spread very easily. You will also have less plant to treat.
2. Mix 1 tablespoon Castile soap into 1 quart of water.
3. Spray entire plant. Tops and bottoms of leaves stems, all of it.
4. Flush the soil until it runs out of the bottom of the pot.
Repeat weekly and water when needed with treatment until no new mildew is made.
Most fungi, mildew, bacterial infection happen in plants with low air circulation. Indoors there is very little airflow. To prevent it in the future NEVER mist plants and add fan for airflow. ❤️
Use a balanced fertilizer high nitrogen gives them an excess of new growth. To much new growth promotes a perfect environment for powdery mildew to grow.

So, I don’t use fertilizers with this plant, only compost at the beginning of the year since it’s in a large pot outdoors, but that’s really good to know.
Living in North Carolina, we naturally have high humidity here and this plant is in a place that doesn’t get lots of wind.
I’ll admit, last year I was much more dutiful with leaf cleaning, and this didn’t happen. I’ll go through with the treatment and will keep up with regular cleaning.
Thank you so much!

@UrLocalPlantGuy You can fertilized just make sure it is a balanced fertilizer. Some are extremely high in Nitrogen, you don't want that. You need is to be balanced. I'll include my fertilizer write up so you understand.
Fertilizer
You want an NPK fertilizer which will show up on the front of the container.
N- Nitrogen for Foilage growth
P- Phosphorous for root growth
K- Potassium for overall health
It will look like this on the front.
10-10-10
5-10-5
6-8-5
Each fertilizer will have its own numbers and you want each one to be between 5 and 10. The number represents the percentage in the fertilizer. If it's between 5 and 10 for each ingredient your plant will get the perfect amount of nutrients. Too high can burn roots and cause other issues weakening the plant making it vulnerable to disease and infections.
Liquid is better because the plants can absorb it easier. Plus it gives your plants an instant boost of nutrients
