Last year I bought and planted a Starfruit tree (don't know which variety) from a someone local (Southern CA, West Covina area) who grafted it from his own tree. The leaves on his tree looked healthy and floated.. Mine looks sad and folded. The tree I bought looked healthy when I bought it. It flowered several times now but never fruited. Not sure what I'm doing wrong or not doing.. Please help! Thanks in advance!
