why am I getting small parts of several leaves turning crispy brown?

Thanks

Anthracnose (Colletotrichum sp.), a fungal disease, could be at work. Usually the lesions appear first at leaf margins or near the base of the leaf where it joins the petiole, but often they spread, covering large areas of the leaf and killing it.

There are some interiorscape fungicides (check the labels to be sure they’re still approved for use in your state) that you can use to treat this...among them, Clearys 3336 and Compass O (which has translaminar activity, according to Lynn Griffith’s interiorscape pesticide database). In an interiorscape, unless you are spraying water on foliage and spreading the fungal spores from plant to plant, the malady probably came with the tree when you got it, so you shouldn’t have to treat repeatedly if you’re keeping the foliage dry.

Pick off and destroy the affected leaves, being careful to sterilize any cutting tools between cuts so that you don’t spread the fungus to other parts of the plant. Trimming the spots with scissors only contaminates the tool and spreads disease to the next cut.

Probably, this is stress-induced by the transition from nursery to interior (if a new plant)...an otherwise healthy tree in optimal growing conditions would not likely express serious symptoms and could live with this fungus in its system for a long time. You will have to make the economic decision about whether the plant’s appearance and condition warrant replacement, or try to live with it and see if the plant "grows out of it".
