My Crassula has developed these black spots and some of the new leaves have turned black and died. I'm really perplexed because the plant seems very healthy otherwise. The black spots and dying leaves are only on one side of the plant. very odd. There's One little spidar living on the bad side of the plant but I let him stay there because he seems harmless and I figured he'd kill any harmful bugs that try to live on the plant. I don't think that it is from over watering because I use a moisture reader and water very carefully. Any ideas?

Looks like a fungus on the leaves.

Really? Do you have any thoughts on how I can get rid of it? Its an older plant so I'd be pretty upset if it died lol

Hmmm. Have you checked for aphids? Are you in a humid environment?

I checked for aphids. I don't live in a typically humid environment but it has been very humI'd for the past month. I didn't consider that.

Looks like fungal spots..just keep it dry for now. What are your temps now? If it continues to be humid, it can be left drier for awhile. It will eventually scar and you may lose the leaf or it may just heal itself. Jades are very tough. They easily bounce back.

Forgot to ask..is the plant in a container? You may want to position the plant in a sunnier area, south side is really good for them. More warmth.

Boo fungus. Lol is really up and down right now still, temperature wise. Yesterday is was 82 degrees and sunny and right now it's around 62 degrees And foggy. it is in a container so I'll try moving it, right now it's on my porch which is east facing. Hopefully it will just bounce back like you said ๐Ÿ˜Š
Thank you for the advice, Tarev!

plantsmylove, I used to kill everything from over watering. The only thing I could grow were mammoth sunflowers. Lol You should try using a moisture meter. It has really helped me a great deal.

I had that on a Jade one summer & finally realized it was spores from shotgun/artillery fungus.

Tiffany, did you do anything to get rid of the fungus? Or did it just go away eventually?

Love sunflowers! Those look great!

About the fungus, I removed all of the spores I found on plant leaves by removing those leaves, and changed the soil in the 2 pots the fungus was living in. I don't think it can survive in my yard since I don't mulch with shredded wood - haven't been able to find any the past few yrs, but it was making a living in those pots (which did have some shredded wood mulch from a batch of "home made" potting soil I made a few yrs ago.) I put the soil from those 2 pots in a plastic bag in the dumpster, just in case it can get going in shredded leaf mulch. That was last summer, I haven't seen any more of it.

Thanks Tiffany! And thank you for the acorn!
Okay that's what I'll try then. I wanted to repot it anyway, but I was afraid to since I read somewhere that Crassula plants fall apart when taken out of their pots? I'm not sure how true it is but didn't want to take any chances. I guess now we'll find out!
Thank you for the advice Smiling

Happy to compare anecdotes. :+)

A healthy plant shouldn't fall apart. Yours looks absolutely vigorous! That makes me wonder if it needs a new pot? If you're able to add a pic of the whole thing, those who have grand, old Jade plants could advise more specifically.

My experience with the jades I have, grown in containers, they really do not need that much deep container, but drainage is really important. I have repotted some, it does not fall apart, but I do have to put some heavy rocks at the base, and stake the plant for awhile as it anchors itself eventually.

Even if I have some in a bit bigger container, the soil is only half level, so the jade plant grows well.

UV light can inhibit the growth of certain fungus/pests on plants. Maybe your crassula needs to sunbathe a little. Smiling

I'm not sure repotting is the way to go either, it may invite more problems, jades are good in the same pot for literally decades if you do things right.

That leaf spot is very common, the plant will drop the bad leaves, the spots may be fungus I'm not sure, but they are environmental.
You'll see them spring and fall.
I'd not worry, it's more likely that you'll kill the plant with kindness than those black spots...
Atleast that's my experience...

I think cinnamon works best on treating open wounds. But it may work well here, too. I think the active ingredient in cinnamon needs to come in direct contact with the fungus, here it looks like the fungus is hiding "under the skin." But I can't really tell.

It's worth a shot!
The black spots can be picked out, exposing an open wound, I wouldn't do that tho...

Try cinnamon or copper dust.
Chances are, with some good sun and wind, your jade will be fine.
At worst it'll drop the affected leaves.
Make sure to get them outta the pot tho, no sense in letting them fester near the roots!
