What's killing my pandorea vine?
I have two pandorea jasminoides 'Lady Di' plants in a corner
of my yard. They are right next to each other, with one trellis facing east and one facing north. But other than a slight difference in the amount of sunlight that falls on the trellised leaves, they both have the same growing conditions. I'm in the South Bay part of the San Francisco Bay Area, not far from the bay, so the soil here is adobe (clay). I amended the soil when I put the pandoreas in about seven years ago, and I feed them occasionally. During the warm months, I water them via little sprinklers at their bases. This time of the year, they get rain often enough to keep them watered. Here are some photos: http://www.wintertime.com/Personal/Plants/pandorea.html As you can see, one of the plants is not looking at all well. I first noticed it a couple of weeks ago, and it's gotten worse. The other pandorea is showing no sign of trouble. The leaf damage looks kind of like frost damage to me, except we haven't had any nights below 32 degs. here. And other plants that don't like cold nights--such as my bougainvillea--are doing just fine, anyway. There's a Japanese maple that's closer to the sick pandorea than to the healthy one, but it seems unlikely to me that the roots of the maple could be damaging the vine. You can see the trunks of both in the fourth photo; they're about 18" apart. They've been living together happily for seven years. In the closeup photo of the leaves, some leaves appear to be turning brown at the spine, but others have random mottling. So I don't know whether they're necessarily turning brown from the inside out. There's still some healthy growth on the vine, but I don't know how much longer it will last. I looked up "pandorea" and "disease" last night, and generally got results saying that they aren't often susceptible to problems. There was one reference to phytophthora (root rot), but that was all. And again, the two plants have the same conditions, so I wouldn't expect that problem to affect just one of them. Anyone here got any ideas on what's going on and whether I can save the plant? Thanks! Patty p.s. A little "eat your hearts out" note to those of you in the North and East: I was watering my strawberry pot today and noticed a nice big, ripe, strawberry. In fact, it was a bit overripe, because I don't normally check for berries in December! I went ahead and ate it; it was very sweet. I see another one coming along nicely. Good ol' California. :-) |

What's killing my pandorea vine?
Hi, everyone.
I posted this message while a lot of people were probably away from their computers during the holidays. Thought I'd try it again in case anyone has any ideas. Thanks!
