Lime tree leaves turning yellow

Post  tg404 on Sat May 24, 2014 3:48 pm

Hello,

I have a young lime tree which I repotted a couple of months ago. It was doing very well up until last week, when the leaves started to turn yellow and dry-ish at the ends. I've read in other posts here and also other websites that this can be a result of overwatering, but I really don't think this is the case here as the soil drains very very well. There are also a few black dots on some, but not all, of the leaves. Any ideas what this is?

Thanks!!

Is "lime tree" = tilia cordata? If so...I had a similar experience. I acquired two young plants (probably 2-3 years old) a few years ago and the first summer I had major problems with yellowing and curling leaves. The problem recurred the second year, then I planted them in the ground to gain size...they've been fine in the ground. I suspect it is some kind of trace element deficiency or excess, perhaps they're very sensitive to pH, I'm not sure. Hopefully someone has some info!

Thanks for the advice! Unfortunately I have no garden where I can plant them Sad I have been holding back from using fertilizer in case it is some disease and that makes them worse.. but if it is some element deficiency then I guess fertilizer may help... I may try if no one has a better suggestion!

That looks a bit like chlorosis.  One of the causes -- and the most common one -- is an iron deficiency.

Be sure that the fertilizer you choose has "chelated iron" listed among the trace elements.    Excessive levels (from over-application) of phosphate, manganese, copper, or zinc may aggravate iron chlorosis, so follow label directions of the fertilizer you use.  Other causes of iron deficiency in plants include calcareous soil, overwatering and compacted soil.

When you say you have "no garden to plant them", can I ask where you are currently keeping this tree?

I've been keeping it outside on a balcony so it gets plenty of sun! Yesterday I took it inside thinking it may help it cope better... Following everyone's comments I've applied chempak no 3 (diluted to half strength) which is supposed to be good for chlorosis (hoping this is what it actually is!)

Thanks everyone.. let's see how it goes..
