This is my first post in the forum so please let me know if I'm doing something wrong. I bought three Aucuba picturatas and put them down about a month ago one is doing great and two seem to be struggling. They are close to each other on the NE side of my house. All 3 have some new growth but one has a lot more and the bottom leaves on two of them are drooping and starting to fall off. Can anyone tell me if it's fungus, to much sun, to much or not enough water? The last one in the pictures is the one doing well. Any help is appreciated.
