Q.holes in the leaves of some of my plants
I noticed holes in the leaves of my snake plants as well as philadendrum. Is some bug/fungus eating the leaves? I have taken a number of plants down to my senior center where I care for them and the plants in question are not near each other.
I can't determine a cause from just your description, though it sounds like an insect issue. You can treat all the plants with Neem Oil. Neem Oil works as both an insecticide and fungicide and is organic and safe for people and pets.
