Yellowing leaves in Jade plant Crassula tetragona
Comments (4)I've been trying to determine what was wrong with this Crassula tetragona since May. Had suggestions for drainage, potting mix, sunburn, etc., but not one person suspected pests. I never could upload the photo to this post in June, but there is a later photo of the damage in a post titled "What's the funk on my Crassula tetragona" in the cacti forum. Mites aren't visible. I couldn't see them even with a magnifying glass. I needed the macro lens of my "real" camera, then I had to enlarge the image. It begins as yellowing of leaves for no apparent reason. Old leaves are mostly affected, but newer leaves sometimes also. Leaves drop. Some shrivel. People mistake it for over-watering, poor drainage, sunburn, etc. As it progresses, leaves look textured with tiny indentations about pin pricked size. Leaf surfaces get what looks like a brown or black coating, stain, or discoloring. Plants continue to grow and produce more leaves and branches, but eventually only those newest leaves remain healthy. That's where my plants are now. I can save them, but it'll be a huge setback. Worse, they've been in contact with all my other plants, shared a water bucket, etc., so I'll be treating a lot of plants. Hopefully, this mite doesn't thrive so well on other plants....See MoreDracaena Plant- Entire leaves turning brown and yellow
Comments (7)I trust Dave on the temperature thing because he's got smarts and much more experience than I do. Please forgive the long post, but I'm bad at being concise. I certainly don't intend to be critical, but some of the information can help stave off some common but easily avoidable problems. I'm suspicious about what's going on inside that pot. So tell us--how exactly do you water? Do you give a measured amount, or do you soak the soil? Was the plant's root ball very stiff and dry before you replanted it? What kind of soil did you use? Have you ever checked right after you water to be sure that the old soil gets moist? It's very strange for potting soil to need water more than once a week at most. That makes me think the old soil was very peaty and fine grained, and had become so compacted that it was hydrophobic. The best solution to that is to break up and remove all of the hardened soil and replace it with fresh soil, but this isn't a good time of year to do that kind of work. But simply submerging the pot in a bowl or bucket of water until no more bubbles come up (which may take a while) will rehydrate the compacted soil and make it easier for it to accept water normally. For moisture management, your finger is fine so long as it reaches all the way to the bottom. My concern is that your new pot has a reservoir to catch drained water, which can then be wicked up by the soil and keep the bottom wet. The issue is that roots need air to get the oxygen that lets them do their job, so they suffocate, rot, and die if the soil they colonize is wet for any length of time, and obviously can't supply the plant with water. This adds up to overwatering, which has almost the same symptoms as underwatering. Then the plant has to spend energy regrowing the lost roots, which eventually weakens it. That's why we tell people to remove the reservoir so the pot can drain into a saucer and to remove the drained water right away so it doesn't get taken up again.

Comments (9)Hello Hank. That's quite a dramatic change isn't it? I had exactly the reverse of that phenomenon with a piece of jade that I bought back from southern Spain several years ago. The mother plant was very pale almost lime green, very much like your plant is now, that is what caught my attention in the first place. There was a piece that had been knocked off as it was adjacent to the main paseo/pavement so I rescued it and grew several plants from it assuming they would be this pale yellow/green/red edged colour. Mother plant was left to bask in the full Costa del Sol sunlight and heat, admittedly in what looked like a poor and thin soil and with goodness knows what watering it as and when...dogs I mean as there were a lot being walked! Every piece I cut up rooted and went on to produce the usual deep green leaves I was more familiar with. They have all retained those nice red edges, but it appears to be the change in growing conditions that has caused the colour change in my case, nothing else I'm sure. That said, and this being the reverse, I would definitely unpot yours and inspect the roots as with you saying it's been wet of late, maybe there could be some root issues starting....so just to make sure. The lower leaves should as you say, drop first, upper leaves yellowing is often a bad sign. What kind of mix is it planted in...the original or has it been repotted? Mine are in very gritty fast draining mixes so no rot issues so far...but they do live inside my gh x365....See MoreJade plant yellow leaves
Comments (1)Die and fall off. If you continue to get yellow leaves, you have a continuing problem. May need to repot in a faster draining mix. Make sure your pot has a hole and is not too big for the plant....See Moremello_mcqueen
