It’s going to be a problem with watering - if the leaves don’t come back in spring it will be dead.
Do you grow everything in pots or can you plant some things in the ground? I’ve noticed with your questions quite often the issue seems to be around watering, either too much or too little. Planting in the ground will make this much easier, if you can. Don’t be disheartened, watering is a tricky thing to get right and even hard to advise on it’s a bit of trial and error until you get the knack, and it sounds like you have the right approach to keep trying and growing lots of different things
Remember with the acer, it was super hot this week and the leaves much just be frazzled.
