spots on sunset jade

11 years ago

Hi, photo{{gwi:807}} I have a large and stunning sunset jade. the leaves are turning an unhealthy looking yellow with some dark dots and larger spots, some leaves are dried at the edges and some are dropping, also some are fine but I know how fast that can turn bad. This summer I had a mealy infestation. I am not seeing any mealy or ants on this jade. This is one of the few plants{{gwi:807}} I did not wash off down to the root ball with insecticidal spray. So wonder if I must? The plant is about 3 feet tall with a main stem about 3.5 inches thick, so it won't be easy. Any ideas what this could be? Mites? Spider Mites? What is the difference? What should I look for? Do you treat a sunset jade the same as other succulents (insecticidal soap)? Or is neem better? Help.

Yeah, my 'Hummel's Sunset' does that, too.
Seems like all the pale variegates have a hard time Spring and Fall with the moisture and the sunlight, et cetera. I still haven't found a happy medium as far as shade/sun is concerned. Can you bring it in at night? That'll probably help.

Josh,
Wow, could be awesome. Not because yours gets that too but because it can possibly be unrelated to any kind of pest. After the summer of mealy's I've been worn out at the idea of a new pest infestation. I'm in San Diego, do you think night temps of 50 degrees can be a problem?

I'll try it tonight. But could it ever acclimate, or do you know what type of succulents might be the most hardy in changing temps? I live at the bottom of a canyon, about a mile or 2 as the crow flies from the ocean. I wanted to plant succulents throughout the yard but the top of the slope has a bit more climate variation. I'm trying to figure out what type of succulents I can plant there in the ground. Would Aloes or green Crassula manage the "less protected" top of my slope any better? If you know or have any ideas I would value your opinion. In the meantime I will put my sunset jade in a more protected area. Thx!
Anna

Hey, Anna, I think it has to do with the overnight dew. I could be wrong. Hopefully some of the more experienced members will comment on the possibility of pests.

Green Jades do much better for me with the outdoor transition.

Josh,
Thanks, that makes a lot of sense, I find the dew on all my plants in the morning. That seems like it could cause the brown spots if the dew leaves drops of water, then the sun hits it and burns. I brought the plant inside tonight and will continue to do so and see what comes of that.
Thanks so much,
Anna
