Hello I bought this small Japanese maple tree. When I purchased it the leaves had some holes in it but it was on clearance and I thought I would give it a shot !! It's condition has continued to worsen and now it almost looks dusty....I have inspected the leaves (including the undersides) but I do not see any pests!!! Any thoughts ??

Welcome!

Did the dusty stuff show up after you brought it home? Are the holes getting more numerous? Where are you keeping it (inside or outside)? I would start by giving it a warm soapy bath then see what comes back.

Thank you for the response !! The dusty stuff showed up after I brought it home. The holes are getting more numerous and I keep it outdoors in a large pot. I have another Japanese Maple and I have never had a problem !! Sorry I am new to this , what type of soap should I use ?

A little dish soap in warm water. The idea is to see what pops out but also to see if you have a mildew problem. Have you gone out after dark with your flashlight to see what happens at night? Best done at 10 or 11pm or 4am. Rolling on the floor laughing

If you have a bottle of beer, pour some into a container and put it beside the tree. I usually use a tuna can but anything about that tall and filled half full of beer will work. If you use something like the bottom of a water bottle, bury it so the top edge is almost even with the soil and pour an inch of beer in. Check to see what you've caught in the morning.

If you haven't repotted, don't. Don't fertilize. Make sure the tree has good air circulation (the major cause of mildew). Keep it watered but don't drown it.

Thank you kindly !! I have not checked at night yet . Do you think I have a mildew and pest problem ??! I was thinking maybe so...I was concerned when I bought it bc of the holes but it now appears as if it is being chewed on the sides of the leaves now ...maybe slugs in the pot ? I have not repotted it. I have only had it two weeks!
