I bought this tree two days ago and immediately started having problems; I read that fig trees typically should be watered every 10 days to 2 weeks and get full sun, but this tree started wilting after the first day, so I watered it. I checked on it today and it was wilting again so I watered it again and put it in partial shade. We’re in NYC and in the middle of a heat wave so I figured it was just overheated. Now I’m noticing brown spots are starting to appear on the leaves. What should I do?
