We tend to press the limits and this year our jade trees suffered as a result.
We left them out too long into the fall -- they were too cold for too long one night. The following morning we noted the leaves were dark and watery. Imagine lettuce gone old or impatiens thinned out after the first frost (below). That's what we saw.
Here's what we learned, and did.
After the second hit, so many leaves have been lost that it's just a stemmy mass. All that's left are the lower leaves that were protected by their fallen comrades.
Jade can take more cold than an impatiens, but a limit's a limit. In this case, both our jades were under cover of the porch roof, one closer to the open air than the other. One looked like it would lose all its outer foliage but keep the interior and lower leaves. The plant more exposed to the night air, had damage on all its leaves. That meant its branches had taken a hit, too.
It can be hard to tell right way when a jade's branches die. We just hoped the trunk hadn't been hurt.
Where's the picture? No use taking one. In the overall, they still looked okay. What we saw was the off color of the foliage, and that they felt less firm.
The plant that had a bit more shelter than its unfortunate buddy -- in fact, its companion's canopy had been part of its protection -- stayed that critical degree or two warmer. That was enough that many of its inner leaves survived where the tree's
own outer layer of leaves trapped some warm air.
It will be a year before they're back to cat-hosting status, though. Sorry, Olive! (Click Water, fertilize indoors in March in the links at the bottom of this screen, to follow this jade's progress.)
