Thank you all for your input and advice. And sorry for the suspense - I couldn't find the camera cord. And another apology - I said "soil", but should've said "mix": I've got them growing in metro-mix 830 (peat, composted bark, perlite, vermiculite, dolomite lime, and blue chip). Below are links to the pics of the trees as they live in their environment. I posted links rather than the pics themselves so that I could keep the images large enough to show as much detail as possible. Houstontexas123 thanks for that link. After comparing mine I would say it looks like their iron-deficient leaves look most like mine, but again, when it comes down to it, I can't say that any of them look anything like mine. After reading your generous comments above, and reading the back of the metro-mix bag (where it recommends a constant application of fertilizer after at most the third watering), and contemplating my own ignorance, I'm pretty much coming to the conclusion that my poor citrus are deficient in probably pretty much just about everything. Heh. I guess what took me so long to wake up was that it took me so long to hit bottom. My Meyer is six or seven years old now, and has been producing happily and abundantly in the same pot until only last year without aid of any more than a general granulated house plant fertilizer that I put in the water when I brought them in for the winter. : you can see the newer growth is even yellower than the old growth (you should be able to enlarge the images by clicking them if they don't automatically fill your brower). : older growth is yellowing out and dropping off. You can see a few fruit, also sadly yellowish. : newer growth yellower than old as well. I looked around the internet and town good and long for Vigoro citrus and avocado fertilizer but couldn't seem to find anyone who was selling it or could order it, so I picked up a box of Dr. Earth's Fruit Tree Fertilizer. It lists citrus as a primary use, so ought to address my flagrant nutrientlessness. It's quick-release too, so hopefully I'll see some results soon.

Hi Sue, Ummmm my delphs don't die back till they get frosted. However by the end of the season they are starting to pale a bit. But my growing season is very short. I would just wait and see if they come back next year. Delphs are pretty tough. The summer before this one, while I was away there was a huge wind storm. When I came home my white delph at the front was broken and flattened. I cut it back to the ground.....and it grew and bloomed again by the end of the season. It also came back huge this year. I also had a fancy lilac that went dormant mid summer last year.....but it came back this year just fine and even flowered. Gardening is a lot of just wait and see....and many times you will be pleasantly surprised. Sierra

Katsols, the problem could be you let it dry too much, thus shocking the plant. Are you sure the soil was bone dry? It may look dry at the top but where the roots are could have been still wet. Though I doubt that is the case because if too wet the whole plant will tend to collapse. If all leaves were droopy when you watered and the two outer leaves have not revived, try placing a clear plastic bag over it for a few days to see if they perk up. DO NOT leave the plant in direct sun! Place it in a bright spot. This should help the plant if it was shocked by being too dry. The leaves should revive but if they do not you can always cut those affected off. Take off the bag and return to it's original spot. To avoid this from happening again, stick your finger into the soil down and inch or two. If wet, don't water,if slightly damp then it is safe to water. The key is to avoid the extremes too much or too little water. If you rather not stick your finger in, then take a sharpened pencil and stick it I the soil. If it comes out wet, don't water. Hope this helps. Irina may have some more ideas or tips to share. She's very knowledgeable. I sure she will post as well. Dave

It could maybe be a bug ? take a leaf back to the Nursery and ask, or maybe get hold of your Extension Agent.... maybe Tom here could help.... have you sprayed or anything, to try and control it ? this is sure the time of year for all this nasty stuff, what with the heat..... and usually 'this too shall pass', so don't give up, the plant should live thru' it... and Mulberries drop their leaves in the winter and come back in the Spring, at least mine do, and this year it had a bumper crop, the birds really enjoyed it !............sally
