I recently purchased an Emperor One Japanese Maple and noticed after a few weeks that a few of the leaves have these brown spots. What can I do to prevent this?

Brown spots can indicate a fungal disease or they may just be sunscald. This can happen when the tree is growing in a shady spot in the nursery and then is transplanted into full sunshine when you get it home. You can pick off the affected leaves just in case it is a fungal disease. This will keep the pathogens from splashing onto healthy leaves. Best wishes with your new maple!
