New growth during the summer periods can often look a little misshapen and very tender in the heat of summer. If the mature growth is looking healthy, you are propably ok.
However, it does sound like you are fertilizing quite a bit. Japanese maples dont need much fertilization, i would defintitley stop fertilizing at this time of year. And lower yout N numbers. It causes new leafy growth on the top of the plant, that might not harden off before your Totonto cold weather rolls in. I would stay with numbers around or below 10 next year.

As for watering, steady even water is best. Since yours is in the ground, it propably needs water every 3 days or so. Depends on what mother nature gives you. Hopefully the soil is good draining soil, so the tree is not getting drowned, the roots dont like that.

Good luck and stay away from the fertilizer til spring and the lower the amounts. Checking your soil, will tell you if you even need anything.

We maple lovers tend to baby our trees to death sometimes.

Thanks for the help Mike . I have cut out all fertilizing and watering until I see that it needs water . I have a lot of clay here and I'm guessing its a little of both .

Clay is the most saturated soil type there is.
