Mike I been checking the mail box everyday waiting for your package..nothing yet...did it get sent when you said?

Sorry I been so busy lately and I lost your email. Please email me.

Mary

You got e-mail my friend...

I was in the process of rooting some big leafed jade for you too..Wait till see these babies..

Mike..:-)

Where are you located? I'm in Southern Ontario and I've never had this problem after leaving my jades out all summer last year and for the last week or so this year.

If the leaves are molding then it's probably due to moisture as you suspect. You might consider moving the jades somewhere where they can get more air flow, or sunlight to dry the leaves in the morning.

Can you also describe the mold in a bit more detail? Maybe some pictures would help as well.

Thank so much Mike! Will be in touch buddy:)

I just gave up on most jades. Not a problem with dew but with high humidity and the salt spray. They sure don't like to be wet. I suppose you could put some kind of dehumidifier or heater with them, though then you have to worry about being electrocuted.
Good luck.
Tally HO!

Tally,
have you ever tried growing Jades in pure mineral mix?
Not Pumice or Turface necessarily, but something that is mostly granite or quartz?

Jades actually receive most of their moisture from fog banks in situ, and it seems
that the ambient humidity would be a boon....so long as the soil-mix held very little moisture.

I'm just trying to think of something, as no one should be without a Jade!

Beachplant, I have been preaching that for years. Yes they live off the fog in Africa, it builds up on the leaves, and the leave facing down drop it on the roots, they live in cracks of rocks, so soil is scarce for them, and the goat, sheep eat the leaves, including all kinds of grasshoppers etc. that is how they get pruned. They can live on very little care. They are survivors. The sun comes out and dries off the leaves, or the dry day time humidity takes care of it. I belong to a group where 50% of us have been to Africa or Madagascar. The speakers also have been all over So America where ever they can find cactus, we get speakers from all over the world if they can speak English. Calif, is loaded with extremly gifted informed cactus and succulent members. Who teach and inform all of us novices. Norma

They must have great air circulation and only water in the morning so they dry off by the evening, or give more heat to get rid of the extra water. Or if you get a lot of fog, just don't water it won't be necessary. If they can be grown in England South and North with no problems then you should be able to grow them as well, England had floods, yes, some of them floated away, or sat in water for several days, that they did protest, however when they froze my friends did not toss them out, and would you believe it they grew back so it was not dead after all. You can grow them just give them another chance, and yourself another chance. Norma Did not proof.

I have a couple of jades. The problem is the humidity is 90% or more for weeks and weeks and weeks and months. It's not like fog which burns off in the morning, it's humid 24/7. There is no break in the middle of the day, it's 99% humidity at noon and midnight and all hours inbetween. I've tried jades in about every mix you can think of. A few will live here, most die a painful death. The cactus/succulent dealers don't grow them either. I grow most of my collection on the front upper roof of the porch, full sun all day, great air circulation but salt spray, humidity, wind, ya gotta be really tough to grow in Texas LOL!

The past couple of weeks the humidity has been almost 100%, winds average around 20mph so everything, and I mean everything is covered with salt spray, it's been overcast and last night we had about 6-8"of rain.

The garden has sand, you can build a sandcastle in the yard, the city was raised after the 1900 storm with dredge from the Gulf. After Hurricane Carla in the 60's the city dumped truckloads of oyster shells along the city streets for people to fill in their yards where the soil washed away, dig down about 4" and you hit a thick layer of oyster shells. It's a bugger to dig through!
Tally HO!

I bet that salt spray does them in. But I did see them along the Coast on the South Cape among the rocks and the water line. They seemed happy campers. I jut don't get it, it was exactly where the Inian ocean joined the Atlantic Ocean, there were actually Penguins nesting at the Cape. Norma

Here's a question regarding my jade plant. It is doing very well right now and is getting quite potbound at the moment.

Is edema a common thing with jades? I have some little white bumps popping up in the 'pores' of the leaf itself. It would be difficult to take a photo of this since they are very small.

I'm calling them pores since they remind me of the pores on my nose...lol. When I run a finger over these bumps, they are very slightly raised and are white. They aren't easily removed! I could have overwatered it at some point and maybe edema is the cause?

Or could it be something else? As I mentioned, the plant on the whole is very healthy, and is slowly getting a bunch of new leaves. My question is really more cosmetic (and curiosity) than anything else!

Lastly, when I bought the jade it was in fact several plants in the same pot. I have not separated them, but rather potted them together. Hearing mixed things about keeping jades in a tight cluster, I wondered what you guys thought?

If I remember somewhere on these forums, I think someone suggested they are excess salts excreted by the plants.

I am curious, does it look like the leaves on John's jades provided in the link below?...I hope someone helps you..

Mike-

Thanks so much for your response! I checked the photos in your link, and yes - as a matter of fact, the spots on John's jade plant do look very similar to the spots on my jade.

However, my jade spots aren't quite that numerous or noticeable (and my jade isn't as beautiful as John's!). Don't those spots kind of remind you of spilled, dried milk all over the plant? Of course it's not that at all, but it's definitely something!

The 'bumps' on my plant have an almost chalk like texture when i scrape them with a fingernail... I haven't the slightest. I will do my best to get a clear picture of them soon.

I tend to really notice little things like this on my plants, since I pick them up and examine them closely from time to time.

Anything particular that would cause malformation of the leaf edges? I have a couple leaves that are saw toothed on the end, but still rounded.

It sounds to me like you are describing some kind of scale. (I think this is the problem in the picture above too). They are tiny bugs which feed on the leaf matter. I have solved this on citrus trees by rubbing the leaves with rubbing alcohol, which kills the scale and forces them to release their grip. However, I have never tried this on jades. Can anyone else confirm or deny my hypothesis?

Zach

Those little dots are merely excretions (of salts, sugar, or other compounds) from the pores on the Jade's leaves.
The pores are called hydathodes.

In John's pic, we're seeing the typical excretions, as well as some cold/mechanical trauma to the leaf surface.
After that pic was taken, John's Jade took some serious freeze damage, so I must surmise that it had
been exposed to fairly cold - though not freezing - temps in the days prior to the major freeze.

It shouldn't be anything to worry about.


Josh

Cool, good to know. Ill have to do some research on hydathodes as I've never heard of them. I guess I was wrong. Thanks for the info.

I learned about hydathodes from a member at this site, as well, so I'm glad to spread the word!

One can minimize the excretions by using distilled water, or rainwater (if available).
Also, a well-made soil mix that flushes easily and doesn't have a lot of fine particulate
will reduce the occurence.


Josh

Ok...

I have a couple photos of my jade. One is an overall shot of the plant zoomed out, while the other is slightly closer (as close as I could get without blurring the pic)-- and if you look closely in the foreground at the leaves, you can see tiny white dots. These dots/bumps don't move, so I really doubt its a pest problem. Btw, how do you guys do that fancy multi-pic posting on here? Can you do that in Photobucket?

Side note: My majesty palm had a ridiculously massive infestation to the point that I chucked it. For 15 bucks at Ikea, that 6 foot palm wasn't worth saving! I couldn't cover every inch of the plant with a mister bottle, so I resorted to the garden hose...alas, I failed. But, in the process I saw a ton of spider mites moving about. There was probably more wrong with that plant than just the spider mites, but I'll probably never know. Much later, I had mites on my rosemary plants. A quick spray of those solved my problem though.

Second jade pic: look for the white dots on leaves... they are difficult to see.

Houseplantlover,
"Those little dots are merely excretions (of salts, sugar, or other compounds) from the pores on the Jade's leaves.

Yes, if you select all the pics you want to post, then hit "generate html code" at the bottom of the photobucket page,
the first code option should be the thumbnails, and the second code will be full-size.
