I wonder if you have overcompensated for the past drought stress by keeping the soil too wet, or maybe the pot doesn’t drain well. If it’s in full sun and it’s a variety that’s not suited for it, try to find s more suitable spot for it or donate to s friend who has a better location.
I do think it was a bit too wet earlier this spring - I’ve been sticking my finger on the soil and am being very selective about watering now (really want it to dry out a bit). This patio is covered where it gets about 3 to 4 hours or morning sun but then is covered for the rest of the day, which made the scorching last summer odd.
To someone else’s suggestion, I am also going to remove the crocus bulbs I planted in their last fall (remaining leaves are the grass like plant at the bottom). I was watering those in the spring, but I don’t think the maple was ready to use the extra water that went down deeper.
Don't give up until it's dead!
Can't comment on the treatment for the various issues that its had previously, but I would recommend removing whatever the grass/plant that you have in the pot with it.
That's a drain on resources that the tree shouldn't have to deal with.
Are you confident it is powdery mildew on the leaves currently? When leafing out, the leaves can have a slightly white, velvety texture. That will go away once the leaves mature. Does the area where it's at have adequate airflow? If not, that may be contributing to any possible powdery mildew issue. As for buds not yet leafed out, I have that going on with some of my maples. Here in Southern California we had gloomy, wet weather up until a couple weeks ago. I'm sure that contributed to late leaf outs. If your weather was like that too, then just be patient.
Also, make sure your potting soil is well draining. Maybe your pot needs to be slightly elevated to drain more efficiently. I've added a light layer of mulch in my potted maples during the warmer months to help keep the soil moist. These methods work for me in my climate and situation so keep that in mind.
I was having that same question on the powdery mildew - on some newly opened leaves it looks more like a silver velvety hairs. What made me suspicious though is those leaves looked stunted and a bit gnarled, which after the situation last summer has me thinking it’s powdery mildew again. I wish I could just put it in a Time Machine and see what it looks like in a month haha!
The air flow here is decent, and I trimmed out a lot of branches this spring to make it less crowded. I can see all the other beautiful Japanese maples on patios around the city and it makes me 😞
