I recently bought a limequat. I thought I could leave it in a pot until I had a chance to plant it in my yard. (zone 9B) After about a month it started getting yellow leaves that dropped off the tree. I repotted it thinking that might help. It hasn't. Some of the branches are leafless but they are flowering. Hope some one can help.
It could be a number of things but it sounds like it could have cooked. Do you have it on a really hot surface in a black pot. I have had some trees do that when they got too hot in the pot.
If that was the case, you should see new leaf growth as soon as it cools down or if you put it in a cooler location.
Like I said, it could be a lot of other things too.
My first suspect would be a watering issue. Over and under-watering could both potentially cause those symptoms. If it was rootbound before, then the original problem could have been caused by underwatering (with a rootbound plant, there are tons of roots and not too much soil to hold moisture, so it becomes difficult to get the plant enough water). I don't know how long ago you repotted, but plants can go through a little transplant shock when you repot them, or it could still be leftover symptoms from conditions that made it unhappy before you repotted. Or if you've continued to water at the same frequency that you did before you repotted, it might be getting too much now--when you've got more soil around to hold water, the plant won't need to be watered as frequently as it did before. You can check by sticking your finger down a few inches into the pot and see how wet it feels--if it's sopping wet then you're watering too much, but if it's bone dry it may need more.
Thank Goodness For this thread, my beautiful Lime tree is a tree of buds and lost its leaves, it has been moved, but is still in a black pot, so will re-pot afer the big deal today.. oh.. Happy ThanksGiving to all!
