Yeah Ugni seems to do best in shade in 60 degree san francisco fog.
I gave up on them , but they are worthy of a spot if they grow and fruit great at your location.
Seems to be a northern Cal , PNW plant.

Chilean guava (Ugni molinae).
In the span of 5 years I have bought at least 10 of these plants all due to having replace dead ones. Regardless of their iterations, they are extremely sensitive. IME just touching the branches lightly to inspect growth I saw said branch die back in a few days for no reason. What's available to buy are just too small and expensive to keep trying to grow. I'mma pass on these for now. Soursop is easier to grow then these in FL 9B lol.
