I get citrus leaf miner that can cause havoc with new growth, but read once
not to fertilize after the end of Dec as the leaf miner come towards the end
of summer. Seems to be about right for Newcastle. The first attack wasn't
until mid Jan, but fortunately as the trees hadn't been given a good burst
of food for a month there wasn't much new growth at that time.

Weekly application of white oil seems to limit the problems. Rogor
(Leybacid) works a treat on my grapefruit and valencia orange, killing the
grubs already in the leaves - but was a disaster on my limes. The bottle
says not to use on Myer Lemons as it can cause leaf drop - it also does on
limes ! - mind you I didn't get any leaf miner on the limes - there were no
leaves for them to get into. Lime recovered quickly and is now cropping
well.

Cheers,
Geoff

citrus gall wasp infestation can also cause new growth to curl up from
the plant being stressed, and as far as i know the only way to get rid of
it is to remove the infected branches (the ones with the little swollen
nodes on them) and use white oil to try and prevent reinfestation, keep
the fertilizer and water up to the plant too.
hope this helps

It may be citrus leaf miner. If the curled leaves have silver/grey
trails underneath then this will be the cause. There is no cure but
white oil can prevent it. I made my own using equal parts vegetable
oil and water with a dash of detergent. Spray this on new foliage. It
worked for my lemon tree in a pot but it's since kicked up its heels
as I can't water it enough in Brisbane

Plants will fall victim to these problems if the basics arent met. First
of all make sure you have the plants in a situation of plenty of
fertiliser, chook manure works wonders with citrus, and silverbeet will
really take of with this stuff.
Proper watering is also a necessity. If you overdo the watering, that can
also create a problem with root rot. (same effect as not watering, not
enough nutrients reach the plant) So if what youre doing is not working,
dont do it for a while and try something else. (sounds inane but it works
for me)
I have never had any problems with silverbeet, and its seen as unburstable
locally, so it may be something a simple as shallow depth of soils, not
enough drainage, soil too sandy soil hasnt got enough humus.
Let us know how you go. Also try changing position of plant next time, as
this will help assess the rpoblem.
