Hey,
Went to my parents place over Christmas and looked over my coffee plantation, 24 K7 trees, which are all doing extremely well. They are flowering for a 2nd time in 6 months and their are more cherries each time. Most are over 51/2 feet and have not lost one since I planted them near two years ago.
I hope this year will produce more cherry and that they flower around the same time so I can pick them in one go. It is possible to get "flower syncronisation" but that requires irragation and not quite so much rain as Mt Tamborine.
Have a Great New Year all.
