Q.My avocado plant leaves started to brown
I put the plant outside in sun -it was a 60 degree day on Long Island. I haven’t put it outside since-did I burn the leaves or shock the plant? What can I do? Thanks

Was it turning brown before you put it outside or after? Usually sunscald makes the leaves turn whitish.
You can move your plant outside in the summer, but first you need to "harden it off." A sudden change from indoors to full sun will burn the leaves. They need to spend time in the shade first and gradually moved to more and more sun.
It could be from wind or salt accumulation in the soil or even too much fertilizer. The link below addresses these issues:
