Lemon Bush

donna_marie, Nov 12, 10:16am
Hi my lemon bush is getting yellowing on its leaves and the leaves are then going brown and curling up. Also my lemons have black and some brown patches on them. I'm guessing it needs feed but have no idea what the problem is, so don't know what it needs. Any help would be great, thanks.

Mine went like this after the heavy frosts last winter. Lemons had frozen solid!
I don't know if I did the right thing, but I cut it back after the risk of severe frosts, gave it a feed of sheep pellets & kept the water up to it (it's under the eaves & gets little rain) & it's coming away again well . thank goodness, as it's an old tree & I would have been upset to lose it.
Good luck.

Yellow could be: Overwatering, underwatering, lack of nutrients, stress.
Black and brown patches -
Alternaria rot
Blue and green mold
Anthracnose
Botrytis rot
Sooty mold
Septoria rot

any number of things, check one of the problem guides on the net - with pictures.

You scaremongering?
We had several -7 degree frosts in Canterbury . where I live a -9 was recorded so I'm picking that's what it is. What poor lemon tree would come out of those cold temps unscathed?

And. what disease would survive those temperatures!

A dose of Ebbs n Salts, followed by some Citrus Fert and water will bring it back to life. Neem Oil for black soot on leaves, or a damp rag and wipe it all off then spray.

The person asking does not mention frost, what size or how old the tree is or provide pictures.
I was trying to be helpful by saying there are a number of causes, not jumping to conclusions.

Hey, I wasn't having a go at you, did you not see the *winkie* face?
She lives in ChCh. that's all I was going by.
I lost a couple of youngish citrus, thought they were safe enough after a spray with Vaporguard . nope.
My old lemon tree had a real knock back.
We've even had a couple of frosts in the last week or so . so much for global warming.
