Pothos - Yellow Leaf - Sign of Overwatering?
Comments (19)Hi DS I've been an interior landscaper for 30 years, and I have to consider myself pretty much an expert on pothos, having cared for ten's of thousands of them in all sorts of light conditions, etc. Pothos are pretty tough little customers, so they're good for beginners to experiment with. When their roots are staying too wet for too long, the first sign you will see is browning on the edges of the leaf stems (the stems that attach the leaves to the "vines"); the next sign will be small brown tips on many leaves, newer and older both. Conversely, if its not getting enough water, the older leaves will turn yellow. I think I'll have to disagree with advice to use 'temporary wilt' as a diagnostic tool. Your real tool to figure out what the soil is doing, how much moisture it is holding, is to actually feel it with your fingers. You can use a spoon to reach into the pot and pull up some soil,and squeeze it between your fingers. It should feel cool and soft, stick together a little bit, and fall apart easily when touched. Or you can insert a small wooden dowel or kebob skewer, as if testing a cake. When you pull it up, there should be only a few crumbs of soil, and the skewer should feel barely damp. This is the point at which you can water again. (These are the descriptions for pothos, other specie may require different moisture levels.) Now, as to your plant, the answer to your question is that yes, the new leaves may be lighter in color when the plant is moved to higher light. Did you mean you moved the plant closer to an electric light? Or just closer to the window? Just moving it closer to the window would probably not affect the leaf color. Don't worry so much about the vagaries of each individual leaf - just let it grow, and observe the overall appearance. Be aware that since you up-potted, it will be awhile before you see much leaf growth, the plant will occupy itself with growing roots before leaves. I don't know how long you've had this plant, or how big it is, but pothos really don't need to be repotted more than every couple of years....See MoreOsmanthus Fragrans leaf tip turned brown
Comments (25)I bought a one-gallon Fudingzu from Nurcar this spring. It grew right along over the summer. It responds to misting with new growth. Repeat, it responds to misting with new growth. I moved it to the front porch while my deck was being renovated, and neglected the watering. Leaves turned brown at the tips. Moved it back, resumed watering (and misting with the hose several times a day). It resumed new growth after several weeks. Left it outside til temps were threatening to go below 20, then moved it into the garage, which stays app 10 degrees warmer. Again, let it get too dry, since it was cold and dark out there. With the recent dip in temperature, finally brought it indoors to a sunny west window. Dropped a lot of leaves (too dry), but not all. It still has a nice form and plenty of leaves. Within a couple of weeks, set literally dozens and dozens and more dozens of buds, which are now opening. Butterfly's advice to flush salts out of the pot is very good. Osmanthus are said to react poorly to buildup of fertilizer salts. If you want new growth on your Osmanthus, please follow Mike's and my advice: mist the branches. Outdoors, you can just mist with the hose several times a day, til the branches drip. Indoors, maybe you can water it in the shower or tub, spraying the branches all over. I'm not sure why misting works so well with Osmanthus (I do it to my other potted plants outdoors as well). Maybe the humidity in its native habitat. But make sure, this really does work....See MoreHelp for yellowing Pothos!
Comments (5)FYI - some nutrients (N, P, K, Mg, et al) can move about inside the plant. Others are considered immobile or nearly so. The immobile nutrients, like Ca, must be available in the soil and in the nutrient stream at all times for normal growth. When there is a deficiency of any mobile nutrient, the plant will rob the nutrient in short supply from other plant parts to provide what's needed for new growth. Normally, the plant robs these nutrients from older foliage, or foliage closer to the stem/trunk in plants with branching structures. After the nutrients are extracted from the sacrifice leaves, they are shed. We don't know if it's light or fertility that's causing your plant's leaf loss, but there is no doubt that 2 years w/o fertilizer virtually insures more than one issue related to nutrition is in play. I'd say a good plan would include A) trying to fix the low light issue, B) get started on a fertilizer regimen that makes use of a high quality soluble synthetic fertilizer (like Foliage-Pro 9-3-6), C) get your watering under control by using a 'tell' to 'tell' you when it's time to water. If the pot the plant is in was plastic, you could easily tell when it needs water by hefting it to test its weight, but that doesn't work as well for clay pots - which ARE the best (conventional) choice, IMO. Using a 'tell' Over-watering saps vitality and is one of the most common plant assassins, so learning to avoid it is worth the small effort. Plants make and store their own energy source – photosynthate - (sugar/glucose). Functioning roots need energy to drive their metabolic processes, and in order to get it, they use oxygen to burn (oxidize) their food. From this, we can see that terrestrial plants need air (oxygen) in the soil to drive root function. Many off-the-shelf soils hold too much water and not enough air to support good root health, which is a prerequisite to a healthy plant. Watering in small sips leads to a build-up of dissolved solids (salts) in the soil, which limits a plant's ability to absorb water – so watering in sips simply moves us to the other horn of a dilemma. It creates another problem that requires resolution. Better, would be to simply adopt a soil that drains well enough to allow watering to beyond the saturation point, so we're flushing the soil of accumulating dissolved solids whenever we water; this, w/o the plant being forced to pay a tax in the form of reduced vitality, due to prolong periods of soil saturation. Sometimes, though, that's not a course we can immediately steer, which makes controlling how often we water a very important factor. In many cases, we can judge whether or not a planting needs watering by hefting the pot. This is especially true if the pot is made from light material, like plastic, but doesn't work (as) well when the pot is made from heavier material, like clay, or when the size/weight of the pot precludes grabbing it with one hand to judge its weight and gauge the need for water. Fingers stuck an inch or two into the soil work ok for shallow pots, but not for deep pots. Deep pots might have 3 or more inches of soil that feels totally dry, while the lower several inches of the soil is 100% saturated. Obviously, the lack of oxygen in the root zone situation can wreak havoc with root health and cause the loss of a very notable measure of your plant's potential. Inexpensive watering meters don't even measure moisture levels, they measure electrical conductivity. Clean the tip and insert it into a cup of distilled water and witness the fact it reads 'DRY'. One of the most reliable methods of checking a planting's need for water is using a 'tell'. You can use a bamboo skewer in a pinch, but a wooden dowel rod of about 5/16” (75-85mm) would work better. They usually come 48” (120cm) long and can usually be cut in half and serve as a pair. Sharpen all 4 ends in a pencil sharpener and slightly blunt the tip so it's about the diameter of the head on a straight pin. Push the wooden tell deep into the soil. Don't worry, it won't harm the root system. If the plant is quite root-bound, you might need to try several places until you find one where you can push it all the way to the pot's bottom. Leave it a few seconds, then withdraw it and inspect the tip for moisture. For most plantings, withhold water until the tell comes out dry or nearly so. If you see signs of wilting, adjust the interval between waterings so drought stress isn't a recurring issue. You might find this to be helpful. Al...See MoreWatering tips for new plant?!
Comments (6)The basic rule is water till water runs out of pot (that's assuming it has proper drainage), wait till water is almost all gone (weight of pot can be used to assess that), then water again. This may be every few days, or may be 2 x a month...just water when water is needed....See Morelaticauda
