While we don’t have as much of the hardiness problems in Zone 8b, we have big problems with fruit ripening due to our northern latitude.
I am growing a variety of persimmon trees but now that I’ve had the chance to sample a few from my tree and my neighbor’s tree, I am getting discouraged from growing it here.
Background: I picked up 1 Saijo, 1 Nikita’s gift and 1 Jiro earlier this season. Towards the end of the season, I wanted to try out Rojo Brillante, so I purchased that from JF&E.
Only Jiro produced fruits this year. They barely turned color and I brought them in a few days ago. They have softened nicely but the flavor is just blah. Really bland. The store bought persimmons are MUCH better.
My neighbor’s Izu developed much more color, much sooner. It is also much sweeter. I hear it is an early variety.
It seems to me that Jiro is marginal here in Seattle and won’t ripen adequately in a normal year and hence must not be grown. They should definitely not be sold in garden centers as they are every year.
About the other varieties, it seems that Saijo is early and might have a good chance here. Daniel is growing Nikita’s Gift successfully in South west WA but it is a bit warmer there.
Can anyone comment on Rojo Brillante? Is it a variety that needs more heat units than what my area will provide?
Do astringent varieties need more heat than non astringents or vice versa?
