I planted my Staghorn in hopes of getting the red fruit cones but every year they seem to start and then disappear. Any idea why? Thanks ahead of time!
I see that this species is dioecius; that means that there are separate male and female plants. So, you either have a male plant that will never bear fruit; or you have a female plant that isn't getting pollinated.
If you can post a close-up of the flowers when some of them open (should be about another week or so), we should be able to verify that this is a male.
