This is the time of the year we usually start seeing odd lumps or growths on
maple leaves, which are called galls. This is simply a cosmetic issue and
won't harm the leaves or tree. Enjoy this curiosity of nature! More info:

I have a maple tree that I have been growing in my back yard for 3
years now. It is about 6 feet tall. About 1 in 3 leaves has a little
red thing popping up out of it. I am not sure what it is. My question
is what is it and if it is bad how do I fix it. Thanks
