| So this Chinese elm got planted about 8 months ago. It was in a 24 in box. Planted in Socal. I noticed the leaves browning on the edges. Tree has lost some of its leaves. All the pods look dry and brown. Is this a reason for alarm?

Follow-Up Postings:

| Might be a lot of things, fertilizer burn, over watering...mine looks good. Pods happen in the fall, seeds of lacebark... I would say wait and see next spring, cut off the fert...maintain normal watering. hortster |

| I really havent been watering much or fertilizer. Only the sprinkler system plus a bit of deep water about once a week. Does it look like fungus? The pods look dry though. |
|
| From you description, of watering, probable not enough water, especially for a newly planted tree. Do you get the morning fogs? Fungus will need a wet leaf surface for a certain period of time in order to invade. So unless you have frequent fog, or some other factor that keeps the leaves wet, I would doubt it's a fungal attack. Arktrees |

| How often should it be watered? Would lack of water turn the leaves brown at the edges? |
|
| Yes it would. Called leaf burn. Watering depends upon the soil, weather, and the plant itself. There is no hard fast rule. Stick finger 1-2" into the original root ball (not the soil around the original root ball), if it feels moist, don't water. If it feels a little moist, but warm, then water. If it feel dry, then water. Also make sure the water is getting into the rootball. A little water on top so that the top looks moist, is not watering. It has to get down into the root ball.

| first.. they are NOT evergreen in so cal.. are they?? .. even in your zone.. it is pretty near winter ... arent all those leaves going to be falling off soon ... [perhaps i will learn something new today] i deep soak my trees.. MAYBE twice a year... once a week sounds like a lot ... dig a small hole beside the root mass.. and find out if you really need all that water ... it is my opinion.. that trees like to near dry in between PROPER waterings .... and i dont think that is possible with your deep waterings PLUS sprinklers ... especially this time of year.. when there is no real heat.. deep in the soil ... [what is your native soil.. and did you amend the planting hole???] it is not uncommon for there to be leaf damage/sacrifice .. due to transplant [this is where you tell me you did that 2 years ago] .... ONLY YOU can define whether it is too much or too little water... per above.. insert finger into rootball ... and per me.. dig small hole next to rootball.. 12 or 18 inches down.. AND FIND OUT WHAT IS GOING ON DOWN THERE.... guessing is insufficient .... and anyone who gives you an otherwise definitive answer.. is just speculating .... and that is why all the replies seem to be hemming and hawing .... give us some more facts ken ps: the latin name might have allowed me to google your plant.. rather than contemplate the invasive weed trees known here in MI as C. elms .. which i think i learned were asian elms .... |

| Ulmus Parvifolia, Loam soil, Zone 10, tree was planted about 8 months ago. Tree is planted on the east side of my house in full sun. Its been cold here lately. Well, in mid 60's to low 70's which is cool for us. Most of the chinese elms in my neighborhood are adults and have minimal leaf drop. I did not amend the planting hole but did break up the soil good. |

| wikipedia.. that great reference.. calls them semi-decidous .... and semi-evergreen.. whats that all about .. lol .. i will stick with transplant shock.. and a tree that is NOT 'established' ... and i would expect any tree to experience such for 2 to 3 years.. after planting .... after transplant.. it is now coping with interrupted roots.. new sun, wind, and humidity patterns [maybe even sun reflected off the house???] .. it is an understatement to say it is stressed ... IMHO.. w/o a pic.. we can not jump to disease or bugs.. with any certainty ... is there any pattern to the damaged leaves.. no plant .. holds any given leaf forever .... e.g. most conifers shed their leaves in 1 to 3 years ... and on transplant/shock .. its usually the oldest .. interior leaves that are sacrificed ... good luck ken
