How often does my Jade (Crassula ovata) need water?
Comments (0)The common Jade plant, Crassula ovata, is one member of a large family of plants, the Crassulaceae. Most members are from the old world, although a few are from the Western Hemisphere. This FAQ will discuss the Jade plants, and other similar species can be treated similarly. Crassulas are generally succulents, and will usually grow a new plant from a single leaf. Few are frost tolerant, although temps. just above freezing will promote bloom. They grow outside only in a few areas of the US and Europe, so the focus here is on Jades as houseplants. When days grow short and nights are cool, Jade plants in habitat receive most of their yearly rain and also do the majority of their growing. Often times the Jades in the house also react by shedding copious amounts of leaves, leading many people to water their plant. This is to be avoided because the result can be a sudden collapse of the plant. Always allowing the plant to get very dry before watering thoroughly will keep the plant healthy. The dropping of leaves just before new growth begins is normal. To encourage bloom, allow the plant to go without water around the time of the first frost. When the days get short, withhold the water completely and let the plant withstand the cool nights. Several weeks of this dry, cold treatment followed by regular watering will result in blossoms around the shortest day of the year. Regular watering, or nights too warm, and the plant will remain healthy, but bloomless. Propagating many of the Crassulas involves detatching a healthy leaf and placing it on suitable soil. Out of the sun, but in bright light, about a month later roots will form. Watering while the plant is forming roots is unnecessary and can be deleterious if the plant starts to rot. Without roots, the water is wasted as the plant has no means to transport it into the leaf. Stems laid or planted in the soil also will root, the only requirement is that they be sound. Rooting is also easiest when days are shortest, Nov/Dec in the Northern Hemisphere. A yearly cycle for an indoor Jade is usually growth in the early spring, and the plant gets regular water (dilute fertilizer if desired), summer when there is little growth visible and the plant should be allowed to go very dry between waterings. In the fall, around the Equinox, the nights lengthen and cool, and if the plant experiences the cool then water should be withheld, and expect leaf drop as well as some of the branches. If the plant is indoors, it still will likely shed in preparation for the main growing season- the late fall/early winter. When new growth shows (after bloom if the plant flowers), water and fertilizer can be given, but always allow the plant to dry before drenching it thoroughly....See MoreLarge black/brown spots on Gollum Jade (Crassula ovata)
Comments (15)akholt I am not absolutely sure of diagnosis :); but those I would consider. Cinnamon 'fungicide': 2 tablespoons of cinnamon powder to 1 pint of rubbing alcohol (I make smaller amount, you can halve or quarter it). Mix, let stand overnight or bit longer. Cinnamon will turn into 'goo', so you need to strain te sediment (I put it into compost heap after straining). Best is to use either coffee filter or cheese cloth (need few layers). It is quite slow, so I just set a coffee filter over a jar and let it drain. You can use strained liquid as a spray or dab cotton ball in it and wipe leaves/stems. Same could be made using hot water instead of alcohol; but alcohol adds some insecticidal properties. Dark spots will not disappear, the fungicide should help to control the spores. T There are some other home remedies (some better than others, and should be used with caution). Couple recommended for mildew: 1/3 cup of milk in 1 quart of water spray; or 3 tablespoons cooking oil, 1 tablespoon liquid dishwashing detergent, and 1 tablespoon baking soda in a gallon of water; spray at three-day intervals - I never used either of them, maybe they are better in a garden? I like the cinnamon aroma, lol. Ps: soap or liquid detergent help for spray to stick better. I do not like using soaps as they may dissolve natural oils and waxes that help to protect leaves. Vegetable based soap (like Castile) is much better to use. I was looking at the chemicals in Ultra Dawn (very often recommended to use). Here is what I found: Chemicals in Ultra Dawn: Sodium Lauryl Sulfate Sodium Laureth Sulfate Lauramine Oxide aDenat. Alcohol Sodium Chloride PPG-26 PEG-8 Propylheptyl Ether PEI-14 PE-10/PPG-7 Copolymer Phenoxyethanol Methylisothiazoline Colrants I do not know what most of these are...looked up few. Too many chemicals IMO....See Morejade [plant (Crassula ovata) lower leaves yellowing
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 MoreShare your Crassula ovata Jade Plant
Comments (27)Gill, thanks. Your photos are all here, in case anyone is wondering: [Remember my large No1 jade whack from last year?....[(https://www.houzz.com/discussions/remember-my-large-no1-jade-whack-from-last-year-dsvw-vd~3260844?n=4) That's very helpful. I have a very old one that looks absolutely awful, and I even wonder if it's still alive. I think I will do some hail Mary whacks and see what happens. What I'd love to see is a Crassula bonsai done over time starting with a small single stem plant, which I just bought, because mine are defective. I've seen a web page where someone removed the leaves from the 'trunk', and did a mini-whack at the top, but then never showed anything from then on (because there wasn't anything yet). That's what I'm doing right now as of last week. I'll have to post progress. Here is a quick phone photo of one of mine. Keep in mind I've had no idea what I was doing. I grew this from a little cutting. I might ask advice on how to continue with this. What I mainly did is whack, let two branches form, whack, let two branches form. Except every other branch would only grow a single branch from that...I didn't know anything about letting other branches grow on their own....See Morerina_Ontario,Canada 5a
