Tropical Fruit Discussion / Lemon Guava Leaf Spot
« on: May 09, 2019, 08:01:57 PM »
My lemon guava's leaves aren't lasting nearly as long as I think they should. As shown in the pictures, starting from the lowest leaves of this spring's growth (8 weeks since these leaves broke bud), the leaves are developing brown spots near the leaf tip, moving gradually down the edge, with the entire leaf eventually turning red. I thought this was normal initially, but I'm starting to worry that I'm going to run out of leaves by the middle of the summer, and haven't seen anything similar being reported online. One of my Cherries of the Rio Grande has two leaves with brown spots not similar to these, but in general the plant looks healthy, and none of my other plants have shown this symptom yet. I'm in Northern California. It seems like some kind of fungal infection to me, but that might just mean that the plant is being weakened by something else that I need to address, for example low humidity or insufficient water. It isn't currently pushing new growth, so something may be stunting its growth, I'm just not sure what's typical. The tree has been in the ground for a bit over a year.

Tropical Fruit Buy, Sell & Trade / Wanted: Kadsura

Looking for seeds of Kadsura coccinea, or similar Kadsuras, shipped to California, USA.

It looks like the Vietnamese name is Quả Na Rừng. Here is an article about it with pictures: It says there are two types, red and white. I think the white ones have green skin and the red have red skin, but Google Translate isn't perfect. This says 150-1200m elevation, but I've read from Chinese sources it is higher, like 1500-2000 (don't remember exactly). Seems to be native to southern China and northern Vietnam. These articles say it is foraged from deep within the forests, but I've seen pictures of commercial plantings as well. From this article, it sounds like it's not traditionally considered medicinal nor valuable in Vietnam, but the Chinese have recently been buying it from locals for their traditional medicines, leading to scarcity:

From what I've read from Vietnamese sources it grows as a vine before becoming a 15-20m tree. Based on the regions it grows in, I suspect it could grow in areas with mild frost like Northern California, although it may not be able to handle our summers. Only one way to find out.
