How to treat Gray Mold (Botrytis) on Plants
My hoya (hota carnosa compacts) plant has white and brown spots on most of the leaves. It’s been like this for a while and is still growing new leaves and even flowered while it was like this, but it looks pretty unhappy. Is this a fungus/disease or a care issue?
It looks like the plant has botrytis. Botrytis, or Gray Mold as it is commonly called, is a fungus that attacks the leaves, flowers, stems, and rhizomes of house plants. Keep water off of the leaves and provide good air circulation around plants; you may need a small fan nearby. If a plant becomes infected with Gray Mold, it is usually recommended that you trim off the diseased areas, remove any soil that has mold on it, and spray with a commercial Fungicide.
If you are adverse to chemicals you can try this homemade remedy. Put a tablespoon or two of baking soda in a spray bottle, add a teaspoon or two of mineral oil, and fill with water. Shake well and spray all parts of the plant.
