I have a jade plant and overall it seems healthy, but there are some concerns I have! Photos attached for each
1. some leaves more at the bottom are turning yellow with small black spots and shrivelling up/falling off eventually. Is this normal?
2. the leaves at the top seem okay but some have little spots (dark brown) almost looks like a scab but I can scrap them off some are okay after I do this and some leave a grey mark if it pierces the skin.
3. the trunk seems healthy and firm.
4. watering schedule - may 30 (repotted & watered), june 12, june 25, and nothing since. soil is pretty dry even if I put my finger two inches into soil.
5. in a west facing patio window gets full direct sun from about 12pm to sunset.

Any advice on any aspects would be greatly appreciated! I'm a new jade owner and I want it to be healthy!

Thanks!

Welcome to NGA, @terbear !

Overall I think your plant looks very healthy. Jades do lose leaves fairly regularly (at least mine does, and it's at least 15 years old). I don't know what the little specks are -- but it may be getting kind of "fried" in the west window exposure; the afternoon sun from the west is pretty intense. Perhaps @Tarev can give you more of an expert opinion, though Smiling (TIA, Tarev)

Hi & welcome! Pretty plant and pot!!

Does the new pot have a drain hole in the bottom?

@weedwhacker thanks for the feedback, it helps my peace of mind to know that they jades do lose leaves fairly regularly. It's a pretty hot window so maybe I'll try moving it during the day and see if that improves the spots. I'll look forward to hearing from @Tarev

@purpleinopp it does have a drain hole at the bottom, I also added a layer of rocks and there is a plastic tray with holes too! Lots of drainage.

Hello terbear! Sandy is right, jade plants normally drop the older, lower leaves, usually occurs as seasons change. In my area it happens around late winter to spring. Crassulas are cool temp growing plants, active when temps are cool. It slows down a bit during warm to hot months. You might have much better temps than we do, so the drop of leaves is just happening now. At times too, it drops the older leaves to start redirecting its energies to push out new leaves that come out at the tips and anywhere up and down the branches and stem. Oftentimes, this is the stage that succulents end up getting overwatered, thinking it is getting thirsty, it is not. It is just its natural leaf growing phase.

You did mention you have repotted the plant in May, so it is also acclimating again in its new growing condition. Are you able to bring your plant outdoors? It will love good airflow around it, if you can put it in part sun/part shade area to acclimate slowly. Now even if the plant may seem to be a bit slow growing in summer, it still appreciates a good through watering, it still drinks water, it is in summer that I do see it fatten up its stem.

Glazed containers are quite pretty, I also have mine in one, but it does hold water far longer at the root zone, so make sure you check the media has dried out a bit, putting a rock at the base of the plant helps. If it shows damp when you lift the rock, then your media is still wet and delay further watering just a bit more. This plant is quite efficient storing water in its leaves and stem, so you have to allow a good interval in watering.

The question about jade "scabs" has not been answered. We, too, have persistent scabs on our jade. In fact, scabs are responsible for most of the ongoing leaf loss, since last autumn. The plant has become increasingly spindly and bare. It is about 10 y.o. and is a far cry from its healthier years when it was consistently full and lush.

Few jade owners report scab problems. It mustn't be a common malady. Thus far, I have not found a gardening site or forum to actually identify the "disease," and/or offer a knowledgeable treatment. If you know something that the rest of us don't, please, please clue us in. Many thanks. Dennis.

Back up.... Where is this layer of rocks for added drainage?

Dennis, can you add a photo of your 'scabs'? I don't see the scabs on terbear's plant either. Jade plants do have larger than normal pores on the leaf surfaces. Is that what you are looking at?

Hello Dennis, I am thinking what you are calling jade scabs maybe leaf edema that happens and manifests as little bumps on the leaves. This happens when the roots are absorbing too much water that it can release on its leaves. Excess water is accumulated on the leaves and leaves a bumpy mark, turns brown and stays there. At times it will be a prelude for a leaf drop.

It often occurs when one's growing area maybe too humid, or simply overwatering the plant. Giving good watering intervals helps, as with good airflow all over the plant.

Indoor growing environment limits good light and air flow around the plant as well as good gas exchange that occurs at night for the jade plants. Though the plant will still grow, it is not as robust as when it is grown outdoors in its preferred light intensity and temperature needs. That is why I often advise for indoor growers, makes sure media is porous and open, use containers with drain holes, position plant to as much light as you can indoors and do watering intervals.

You have to give us more information:
1) is it grown indoors or outdoors
2) what is your watering regimen
3) in what part of the world are you growing your jade plant
4) what medium did you use when you planted it
5) is it an old plant or newly acquired
6) did you recently repot the plant
7) post a photo of the plant
8) what type of container are you using and does it have drain holes

I'm new to succulents and this group sounds like a wonderful way to learn. I have a large jade plant and am thinking about putting donkey tail cuttings around the bottom to help fill in the pot and shade the soil a bit. What do you all think?

If it were mine, I won't mix in another succulent. Jades can easily fill the container as it gets older and bushier, so the other succulent might suffer from poor light access.

It is a matter of preference too, they do have similar growing needs.

I have to agree jades can grow quickly . Here are two pics of a jade I bought recently. The first on the day I got it in mid feb and another from today . Amazed at how fast it is growing

Hello

Hoping someone can help. Both these 2 jade plants at plant shop about 4 weeks ago. They are in a west facing window and get direct sun in late afternoon. I water every 2 weeks. The soil is very dry at that 2 week intervals. Plants are in a 2.5 inch pot. Live in Canada . 2 leaves seems to have been torn on the same plant. Nothing so far for 2 nd plant . see pics . I don't recall those tears being there when I bought them. Can anyone help? Thanks
