Hi, my succulents have recently been getting holes in them and I have no idea what it is. Please help!!
There are a number of things that can cause marks on Echeveria leaves. Some people have already mentioned slugs and other larger pest eating the leaves. It can be abrasions from being handled, like from your hand, your nails, rings on your fingers. I have cause damage to mine with my wedding ring. I have also created abrasions with my nails or rubbing the plant against another plant or the wall it is pushed against. I can not tell from your picture if they are raised marks or indents. You call them hole, so I am assuming indents. If the marks are raised it could be Oedema. This is caused by over watering.
