Glad to be of service.
Yep, Puerto Rico. My house is in a suburban part of the foothills. Dry heat for part of the year, thoroughly wet heat in other parts. My plants have been through it all and have been very vigorous in their survival. But I must admit, I lack resources (no job yet, small yard with my parents). Trees aren't much of a problem for me, but herbaceous plants struggle in the ground, so I keep them in pots and they're basically surviving. Healthy enough, but not productive in the long term (I don't fertilize, and barely re-pot). That said...
... my Blackberry and Black Raspberries haven't fruited (the first has been thoroughly neglected in a small pot, the latter requires some proactive care and fruits in its second year - in my neglect it grows vigorously but has yet to fruit and the older wood dies off). During its first year (with fertile soil in a new big pot) my Caroline Raspberry seemed productive enough. I feel it would've been very satisfactory in a direct soil planting with compost, manure and a trellis (essentially, proper care; also applicable to Black Hawk). R. probus (a feral specimen given to me from the mountains) is the only one I have in-ground, and is my best success story. Fully neglected, it failed to fruit for a long time in its shady spot, but as soon as I cleared some of the surrounding trees to let in some light, the flowers came. It fruited in quantity for several months straight (tasty and slightly milder than Caroline, but stronger than R. rosifolius), and the clump of plants has grown bigger from the original plant. Seeing as most of these (including R. ulmifolius) are diploid, I'm starting my hybrid experiments with them; but I'm taking a break for now (and except for Caroline, they're not flowering right now anyway).
