What's wrong with me lemon tree?

chillilover starts with ...
I got this from Kmart few months back. I think it's the eureka variety. Anyhow i've manured and mulched the pot. Removed all flowers and tiny fruits it had because i was to allow the plant to grow. Anyhow now the leaves are going all yellow and dropping leaves as well. Please suggest something.

But this was planted 2 months ago. Do you think plants show late shock or something. I'll definately move it out of the sun today and check the pot.

Ok so i moved the plant out of the sun. I think that was the main problem. I put it in a shady spot which get only about an hours sun. I've watered it till it ran from the bottom and also drilled a few holes in the bottom of the pot. Will update later if all goes good.

Just a thought! When I have had a once happy potted plant that seems to have become suicidal I have dug out the soil around the inner roots and found the culpret to be a large garden worm. I disposed of the offender, and the plant began to florished again.

Might be worth shading the pot next time chillilover...the roots may have got a little cooked with the pot in direct sun also..

chillilover The tree may well be suffering in the sun as that puts an extra strain on it - but 1 hours worth of sun per day is not enough for citrus!) - and nor do I think the sun itself is the problem.
Try re-potting but check a couple of things first:
Check the trunk (BELOW the soil level) to see it does not have collar rot (i.e. note if part of the bark covered by soil is rotting/lifting - it is possible that the trunk of your tree is partly covered by soil in your picture. Collar rot could cause the symptoms you have - so check carefully. If you do have collar rot - check out how to treat it - and do so before replanting.
Then check the branch that is affected to see if you can see any holes in it (a sign of a borer - that too will cause a branch to die). If it does, cut off the branch before re-potting.
Re-pot!!! Your soil in the picture looks wet where the water went in - but dry right next to that. It should be evenly wet - otherwise there will be roots that don't get any water (and so will lead to branches dying).
Buy some good quality potting mix that contains wetting agent granules throughout it (they will help the whole of the soil in the pot to retain water), and add some well composted compost and mix thoroughly with the potting mix. Do NOT add fertilizer as it can burn the roots at an early stage - and cause problems!! Then water the soil - use a light spray/drip and allow plenty of time for all the soil to be wet (test by poking your finger in at various places!).
Then re-pot BUT when you do be careful. Make sure the trunk is NOT covered by soil or compost. Water again lightly and as an extra bonus for the tree spray the leaves with a seaweed fertilizer.
Make sure the tree is placed where it gets plenty of sun - and keep watering, every day, for the rest of the summer - unless you notice that the soil is sufficiently moist (on very hot days you'll even maybe need to water in the morning and again in the evening to help the plant recover from the re-potting). In time, I'm sure you can reduce the watering.
I think you have a lovely gardening time ahead of you,
Kathy

chilliover - there is a thread here on exactly your problem: Ants nests in pot plants. Search for it!
