Thank you, Francisco, I'm always appreciative of your valuable comments and insights.
Of the ones posted so far, most are probably too small or delicate for commercial production. I would probably try marketing Longue d'Aout, Valle Negra, Italian 376, and maybe Princesa (seems too delicate, but Pons has recommended it, I'm told). From my July posts, I would also probably market Panache, Flanders, Black Mission, Monstreuse, and maybe Jurupa. I might also try UCR 184-15 because of it's large size and good flavor, but would need to be packed carefully.
If I ever get into breeding (hope to acquire or develop a black persistent caprifig), some of these others would also be useful for breeding.
My new orchard presently has three rows (46 trees in each row) and I figure I need to add at least two more to accommodate the trees I still have in pots. In my plans I've figured I would be generating farm revenue from tree sales as well as fruit but I have been giving thought to needed to plant additional rows to plant more trees of the ones that are most suitable for fresh market fruit sales. I'm afraid this may never end and create too much work for me. Perhaps I should buy some lottery tickets in hopes that I can fund the hiring of one or two full-time workers to get all of the chores done....seriously!
