Why has one of my snake plant leaves turned bright yellow?
Comments (5)I wouldn't fertilize now either. I agree rooting in spring has its benefits, but since you're trying to save the leaf at this time, you can't hold off till spring.. Like Rjm stated, diving the leaf is one way to root. Actually, I've seen pics of how rooting Sans is done..One leaf is cut into 2-3" pieces, set upright/angle in well-draining soil. The problem is, since your leaf is yellow, which normally happens when Sans are over or underwatered, this leaf may not root..When rooting, heatlhy foliage is recommeded..Neither the oldest nor youngest leaves are advised. I'm not saying your leaf is unhealthy, since it's still firm (no rot, right?) So, it might have a chance of survival with some work. It's also a good experiment. I wouldn't use the entire leaf to root. You've a better chance at success cutting into pieces. If you decide to go this route, there's no need for plastic (humidity) In fact, you want the soil to dry out to a degree, adding plstic will keep soil too wet. The best container is a small, shallow dish/tray. Set cuttings a few inches apart. Place tray in medium light (no direct sun) If you use Superthrive Hormone and Vitamins, add a small amount once a month..If you don't have/use Superthrive, perhaps a light dose of Fish Emulsion will help..a very light dose. Good luck, Toni...See MoreWhy are the young leaves of Showy Mountain Ash turning yellow?
Comments (8)I lost a newly planted Mountain Ash one particularly wet year and the nurseryman said yes, too wet -they prefer a light, very well drained soil (rocky, or on a slope). Once they are well established, I'm not sure if that's so much an issue unless perhaps it is planted in a consistently wet/compacted spot....See MoreWhy are my leaves turning yellow
Comments (5)Usually, chlorosis of citrus leaves is due to a shortage of calcium and/or magnesium, but iron is a possibility also. The soil where I live is very short on the cal/mag due to high rainfall leaching nutrients out of the soil. I need to supplement often, more often than I do. Dolomite contains both the calcium and magnesium mineral nutrients. In your case where your tree is potted, an additive with those minerals could be something other than a hand full of dolomite....See Morewhy did one of my leaves turn yellow and die on my dumb cane?
Comments (8)New growth isn't a clear indication that the plant is growing. True growth is measured by a plant's increase in dry weight; so, if a plant is shedding a leaf and growing a leaf, it's roughly in a static state, which is not a good place for a plant to be. I'm not necessarily saying the leaf ISN'T being shed as a result of normal senescence, only that new growth might not indicate an o/a increase in mass. There is no better fertilizer program than one you can control to the degree you know exactly what nutrients your plant is getting, how much of each, and when nutrients will be available for uptake. There is an ideal level of nutrients in the soil and an ideal fractional amount of each in comparison to each and all of the others. Most plants use about 10X as much N as P, and about 3/5 as much K as N. The rest of the nutrients also have an ideal level determined by a function of N levels and the overall level of total dissolved solids (TDS) in the soil solution. Adding tonics, miracle concoctions, or supplements targeting an increase in 1 or 2 nutrients w/o good reason or a strong likelihood what you are doing is going to correct a deficiency, is far more likely to result in limitations than benefits.
