Q.Pistachio Trees
I have pistachio trees (1 male and 1 female). When I bought my house, the owner told me they needed to be sprayed in order for them to produce meat in the nuts but she neglected to tell me what to spray them with. Last year they did produce the shells but no meats. What do I need to spray them with and what other nutrients do I need to give them in order to ensure they stay healthy? Thanks!

It's possible that your trees may need boron. See: http://www.fluidfertilizer.com/pastart/pdf/9P11-13.pdf
