SOS in need of advice on what to do with this guy. It was a huge Croton my husband acquired from work (best teacher award) about a month and a half ago and it was doing great then all of a sudden TONS of leaves just dropped from it. I donāt know if itās not enough sun or not enough water (I give 2 cups of water every time 2 inches of soil is dry???). How do I fix this?? Please help!
