Citrus disease or deficiency?
3 months ago
I have a 2 year old Yuzu citrus. In the spring, I fertilized and began to see new growth. Through the summer, the new leaves didn’t mature, instead stayed small, lightly colored and upward. I reported, gave another fertilizer suggested by the nursery, still the same. The tree started budding but the leaves remained how they were.
Is it deficiency or disease?
Please help. Pictures below .

Citrus cutting deficiency, Help please.
Comments (2)Well here's my guess, that soil mix looks like it stays wet too long, there's algae or whatever growing the surface of the soil. Citrus need superior drainage, and they like to get a little dry before next watering. So perhaps that soil is too waterlogged for the roots, they need ample oxygen to do their thing. This can affect what nutrients are available to the plant, even if the soil has all the right components. You can do a search for 'gritty mix' or '511' here on the forums. Those are both great formulas for your plant, that do as I stated. Hope this helps! Nick...See Morediseases? nutrient deficiency?
Comments (17)Thank you! I think I'm going to get the manganese sulfate, though. I called around Louisville this afternoon and was able to find a high-manganese nutrient liquid (guy on the phone said 2.5%) for $8 per 8 oz bottle. He said you dilute it 1-2 oz to the gallon, which would make it last about 4 weeks. On the other hand, for $12, I can get 2 lbs of manganese sulfate (including shipping) which will last me probably the rest of my natural life. If I ever become a vampire I might run out sometime around the point when warp drive is invented. We have a respirator in the garage in case I want to get paranoid about the hazards of the chemical, but this seems like a less expensive and more direct way to address the issue....See Morewhite sapote: disease or deficiency?
Comments (3)White Sapote should have deep green leaves, and i think you've hit the problem on the head--nutrient. Now, without looking it up and trying to recall my word association to remember stuff, I believe yellowing on old leaves (interveins, etc) means either the iron or magnesium deficiency. Either way, use a citrus fertilizer as your main slow release to prevent the deficiencies on the fruit tree; a mild (diluted) water soluble may help diminish the yellowing, as a foliar application and in the soil. Dont overwater tho in the process, it's winter....See MoreHelp ID Nutrient Deficiency in Citrus
Comments (8)Yeah those new leaves look like they're not getting enough nitrogen. I would go very light on the nitrogen though since it's only been in the ground for a few months, but especially since we're coming up to cold weather (maybe? it's was still almost 90 in my back yard today). I would give the tree some good protection if we get some nights around 35 degrees or lower. Once spring rolls around, then give it some more fertilizer because the ground is probably lacking....See MoreRelated Professionals
