thanks for the reply :) I don't think I get any winter frost here. It definitely never snows here. We mow our Tall Fescue lawns year round here in San Diego. I was looking at some local sod companies and found this fall overseeding guide: http://www.westcoastturf.com/fall_overseed.php That web page is talking about overseeding a Bermuda lawn with Rye. It says to do it sometime between mid October to mid November. So do you guys think I could get away with seeding TTTF the second weekend in November (not this weekend, but next weekend)?

jcjcjcx, Not really sure you want to drive around San Diego County. But here are SOME of the places in SD. Aquatic Warehouse (Kearny Mesa) Pumps supplies, but not a koi store (no koi ponds) - mainly tank species) Koi Koi Living Jewels (Rancho San Diego) Koi ponds; small supply store, but can usually get the stuff fast). The Pond Source (Carlsbad) partnered with Aquatic Warehouse; they have the fish, and the supplies. I also included a link to Phoenix places from their WG society.

Erin, a few things right off the bat. Check the roots to see if you're dealing with rot rot. What potting soil do you have this little tree in? Secondly, 40 degrees is nothing for citrus, especially most mandarins (especially if it's a Satsuma variety, extremely cold tolerant). BUT, we did have temps below that recently, depending on where you are in relation to the coast. Where are you, exactly? I'm in Vista, about 6 miles inland, but up in the hills, so it's milder on my property, save for some cold pockets (my lot slopes downhill, north to south, so the south side of my lot is literally a hole that the cold air rolls down into and sinks - only 1 citrus tree down there and it's a variegated lemon that is holding its own, amazingly, right next to an avocado tree, also hanging in there!) I think you've probably got either a bad case of root rot, or some sort of extensive root damage. Can you not plant this poor little guy in the ground?? Here are the 3 main things that can cause catastrophic leaf drop (these come from the Univ. of Az Coop Extension, very helpful info and quite applicable to us in the San Diego area): 1. Over fertilization. Prevent by following fertilizer application instructions on the product. Treat by watering heavily to flush the fertilizer below the root zone. 2. Inappropriate watering strategy, too much, or not enough water: As a general rule citrus need a deep watering once a month in the winter and once a week in the summer (in ground suggestion, NOT for potted plants, it may be less frequently in the winter, unless we get Santa Anas, more frequently in the summer, especially if very hot. Use the "index finger" test to tell.) Apply water to the entire root zone, well out beyond the drip line. Apply enough water to wet the soil at least a foot below the surface. Check the depth of the irrigation with a long handled screw driver, you will only be able to push the screw driver as deep as the water has gone. 3. Citrus Mesophyll Collapse: Grapefruits are particularly susceptible but any citrus may be affected. It is not uncommon for grapefruit trees to be affected and other nearby citrus to be fine. Leaves and fruit of citrus trees dry up and drop. Stems and branches remain green and living. Rarely is the whole tree affected. Mesophyll collapse occurs when there are unseasonable weather changes. For example if it gets abnormally cold in October for several days and then heats back up above average temperature in November. This fluctuation stresses the trees as they kick into and out of and then back into their winter slow down. It is especially stressful after a dry summer. MANAGEMENT: Remove fallen fruit to prevent attracting fungal and bacterial diseases. Continue to water the tree on its normal cycle and it will leaf-out again in the spring. Do not prune out the defoliated branches until spring, and then only after the tree has completely leafed out. Adding this: Start fertilizing as SOON as you see any sign of leaf push. I had this happen to two of my in-ground grapefruit and was horrified. Was glad to know this was the cause. Happened last winter when we had all the cold, wet weather. Totally freaked out my lovely Rio Red grapefruit. And the owner. Patty S.

It was good BeBe - thanks for everything.
