I'm wondering what's causing these brown spots? Too much sun? Too much water? I have several more pots of Jade and only this one shows the browning. They all sit out in the direct sun all day long and I water them all at the same time not totally soaking just generally making sure they have enough water about every 4 days or so.

Mine will do that if one side of the plant gets too much sun. Although you said they all get the same sunlight and care, that one is disagreeing with you. Or it just wants a shadier spot.

Thanks Daisy, I'll move it to a spot that is a bit shadier spot by my Adeniums which are in a filtered sun spot.

That looks like what happened to my pachyveria..hates being overwatered, so some leaves turned brown fast, so I have learned to be hands off watering it much.

I water my jades thoroughly at the root zone area once a week, and they don't suffer that sudden browning. Maybe you need to lessen watering just a bit.

Thanks Tarev, that's what I'll do then. I've got about 5 pots of Jade and I'll put them on the schedule with my Adeniums. I guess I'm going to have to start a log for each type of plant and when they need watered and when they do get watered.

You can be sure that is not too much sun because you would be seeing red edges on all the leaves (all but one of my jade plants have this feature, and the one that lacks it gets shaded from above). The red edge is a good sign, maybe what you should be aiming for during the cooler months, certainly nothing to be concerned about. I would think from the picture that the problem may at least in part be related to insufficient sun actually.

Watering is very much a personal thing and each place has its own rhythm, but I would not water a jade like an Adenium this time of year. The Adeniums are not real excited about drying out for too long this time of year but a jade (especially one that's not in a lot of sun) can go twice as long between waterings. The way you can know for sure is to keep an eye on how much water they slurp up each time (or stick a finger or moisture meter in the soil to get a better idea of where the moisture is at).

We have lots of jades around here (forgiving climate) and big ones in the ground can survive without any supplemental irrigation through our 3 month minimum summer drought. Up to 5 or 6 months bone dry, with 10 inches of rain total in a good year.

Thanks Baja, here are the others I have. They're all basically in the same grouping as the one with the browned leaves out in direct most all day long until about 6pm here.

Based on the color of the leaves and the distance between them (internodes) I am guessing they're getting some protection. Sometimes you have to physically go out there and watch to see what's going on. (I have a light meter and have spent some time around here doing just that.) Jade plants look different in the sun, the red color and very short internodes being the most obvious cues. Has it been really cloudy lately?

There hasn't been any clouds since the 28th and before that it was nothing but sun for about 3wks Baja, however, I think I have them too close to the house as when I cut the back yard I cut a swath and move the plants back there to where I've cut. I think this time I got them too close to the house and at times they're in shadow in the late afternoon.
