Citrus bugs

[boris]

My lemon trees are struggling at the moment. It looks like insects are eating at the leaves. Or perhaps I need more or less fertiliser?? I'm pretty sure they're getting enough water.  Can anyone help?

It might be Citrus Leafminer @boris - a type of moth. Does it look like something is burrowing through the leaves, leaving silvery trails? It ends up making the leaves curl. If you're not sure, take a damaged leaf into a garden centre. Spraying petroleum-based oil on the leaves can prevent the moths laying their eggs but in your case it might be too late and you might need to focus on helping the tree recover. @CathM might be able to add more expertise - she's a food growing expert.

Thanks Andrea!

I have used Pyrethrum. I'm told that it's natural and should do the trick
