Please help me identify why my citrus leaves are yellowing
Hi Garden Web,
I'm hoping the community can tell me why my leaves are turning yellow.
When I first got the plant about 6 weeks ago, one large older leaf began to develop some yellow spots. I posted here before and was told to not worry. Now about 4 older leaves have the same yellow spots. What concerns me is that now a large amount of young leaves have turned light green with a tinge of yellow. The plant seems to be growing pretty well otherwise and is also budding at the moment. I have noticed that the roots are creeping up to the surface of the soil. Is it a sign that my pot is too small? If so, is it a good idea to transplant while its budding?
I have been feeding with half stregnth Miracle-Gro® Water Soluble Tomato Plant Food 18-18-21 with pH adjusted to 6.0 using vinegar.
Temp is around 21C (70F)
Lighting is 100% artificial with a 50W LED grow light with some florescent lighting in the room
Thanks guys!

Please help me identify this citrus fruit!
Comments (6)It is not Oroblanco, since oroblanco has a thicker rind. I think they are unripe oranges. In Vietnam we have this kind of orange. It has green skin when it ripes. Google 'orange with green skin' you will see many photos of this kind of orange.

Comments (1)Considering the upright growth habit and the big thorns on your tree, it is surely a seedling (as opposed to a grafted or cutting-grown) tree. So it is juvenile. Until it reaches maturity, it won't flower. From the appearance of the leaves, I'd say it is most likely a sour orange (Citrus aurantium), and if so, it is likely a sprout from the base of a previously grafted tree that froze at some time in the past. So the tree is a rootstock. It is possible that it's a grapefruit seedling, but it looks to me more like sour orange. If grapefruit, it will be quite cold-susceptible, especially while small. Sour orange is fairly cold-hardy and may be ok, especially if it is in a protected site. In either case, the lack of fruit is the due to the juvenility of the tree. It needs to get substantially taller, at which time it should start blooming. 9 feet is likely close, so it could be in the next couple years, assuming you don't prune it off, and that it doesn't get frozen....See MorePlease help identify my citrus
Comments (1)Its difficult to tell what it is from the photo, have you got one of the leaf from the top?, from a photo of the whole leaf you can narrow it down a bit, but it is difficult to be exact, it depends on the size and shape of the leaf, and the petiole size/shape in relation to the leaf For it to flower depends totaly on what it is and wether its been pruned at all, from when it was planted it keeps count of how many leaves it has grown, and when it gets to the right amount it will start to flower and produce fruit, if you trim bits off the top the leaf count is reduced, so it needs to grow more to age enough to mature, so with all citrus grown from seed its always best not to prune at all lemon and lime can be fairly quick, sometimes 3 years usualy more like 5 years to flower and fruit, grapefruits can be far slower , more like 15 years Has it ever flowered? What plant food do you use?, If its not fertilised and watered correctly it will slow down the growth and can prevent it flowering due to lack of the correct nutrients, too wet can prevent it flowering as well, you are best using a citrus feed in the water when the plant is dry a few inches down, then soaking the plant, they like to be dry then soaked then dry again...See Morewhy are my river birch leaves yellow? needs saving please!
Comments (22)Yes, that is surely not a fungal problem. Find another "expert", lol! For the record-which BTW I will surely repeat many times, as it just never sinks in....the overwhelming percentage of plant performance problems are environmental, not an insect and not a pathogen. I repeat........blah blah blah......blah blah....blah blah blah blah. There, that surely won't do it! Yet time and time again, everyone immediately makes the erroneous jump to insect/disease. And of course, they want to know what to spray.....or better yet-by which I mean worse still-they come here to tell us how they sprayed some pesticide or other.....and are now seeking input on what might be ailing their tree. Anyone besides me see a problem with this order of things?...See More

6 years agolast modified: 6 years agoI took the leap of faith today and pulled it out of the container. It looks like it was very root bound and therefore nutrient uptake was limited. I had no choice but to gently loosen up the roots and re-pot in a 2 gallon.
I am in Canada in the middle of winter but I think my plant thinks it is spring based on the artificial light and flowering. Hopefully it doesn't stress it out and cause flower/leaf drop. I trimmed off maybe 10 leaves off. Do you guys think its a good idea to take more off?
I will just water with the water + vinegar for the next month or so. Then I will switch to Miracle-Gro All Purpose 24-8-16 + vinegar which is closer to what you guys recommend.
Thanks all!
