My partner and I had some trouble a little while back when we first planted our tree and found out that our tree was nitrogen and magnesium deficient as the leaves were very light in colour and no fruit had been produced.

We check the PH and fertilize as required with citrus feed but the pest issue seems to have gotten worse. The leave curl in this picture could be from frost? As we are in Winter here in Australia right now and the tree is in the middle of the backyard with little shelter - aside from the fence.

This (see pic) is the first lemon we have seen for over a year and a half, since we got it from the nursery! So I am really hoping we can get a few more without the tree being eaten/destroyed...

If anyone knows anything about this or has experienced the same sort of thing, your information would be greatly appreciated!

Hi Nomiepie :)

What Agricultural zone are you/plant in?

You definitely have insect issues, and I suspect by second photo perhaps some viral issues as well...

Here's a bit on leaf damage by insects/ skeletonizing:

and citrus greening, which is abundant in China, and now Florida...sadly...

But a check with your local Agricultural Extension Office, along with a sample of plant material.; should give you the proper answer on viral/bacterial. At least here in the states, and I'm sure you have something of comparison in Oz.
