Yes, as John asked, can you please provide photos since that will help a lot. I would suggest you remove it from the hot sun until your heat wave passes since the roots go into a semi dormant mode when over heated, after 85 degrees in a pot. Your roots will not use the fertilizer in those temps as normal, and your tree will not drink as normal until the temps do come down. I think Josh here HAS to put his in dabbled sun to protect his from doing what yours are doing. So both Cear and John have some good suggestions. Fotos please? Mike

What John said (except one small caveat). This is a classic sign of a tree that has been sunburned and is severely water deficient. Pull all the fruit off the tree, water deeply until you're sure the soil is watered down 24". Keep the soil moist down at least 18", which may mean watering 3 times a week while our weather here in S. California is still so hot. You don't say where you are in S. California. Temps can vary by almost 30 degrees from the coast to the inland areas. Provide afternoon shade for now until this tree has fully recovered. Whitewash the trunk with flat latex house paint cut in half with water to protect this young tree's branches and trunk from further sun damage, since this tree will defoliate from this. If you keep it watered and protected from the sun, it should start to recover. Here's the caveat: Once you see signs of recovery (leaves that are left perk up, and new flush is starting to push out), go ahead and water well, THEN put down your fertilizer, then water in the fertilizer. Never put down fertilizer when the plant is dry, or you run the risk of burning the feeder roots. Patty S.

Liz, fertilized soil will not be enough for citrus. A couple of things - first off, I suspect your potting medium is too wet and soggy. I know you've repotted, but none of the container folks here like MiracleGro soil, it just compacts and doesn't breath well enough for citrus roots. If you search for "511" mix in this forum, you'll get a great container potting mix. MeyerMike can help you out with that for sure, his citrus do exceptionally well with 511 mix. Secondly, and due to that, I am suspecting you have something fungal going on. When you see round spots like that, it is almost always something fungal in nature. You don't need a microscope to see mites. I can see them with my 57 yo "mature" eyes :-) Mites give a very classic appearance to leaves, they look speckled or stippled. Your leaves are not displaying that at all. Black spots under the leaves sounds like Greasy Spot to me. You'll need to treat with an anti-fungal agent. Also, a tree that pours its energy into blooming, while failing is a tree that is in trouble. It feels that it is dying, so this is its last ditch effort to reproduce itself. More sunlight, better potting soil, switch to a better fertilizer with micronutrients like Foliage Pro by DynaGro may all help. The fruit that fell off looks like wind damage scarring. I would pull off all the other little fruit right now, and let's see if we can get your little tree to put its energies back into its canopy, instead of the fruit. Patty S.

Yes i have a feeling it is sun burn as well, because the side facing the sun (through the window) is green, but the side that was away, the branches have turned yellow and so have the leaves. How can i solve this sun burn problem ?? Is it going to go away ? And will it affect my tree in the long run ?
