Help! Are my Arborvitae trees dying?
Help! We live in CO and planted a row of 6 arborvitae trees last Spring. They were doing well and staying green, and were watered by a drip line on a regular basis until the first frost. When winter hit, we were careful to tie the branches together and bang off heavy snow so that the branches wouldn't freeze and break off. Now Spring is upon us, and the branches are browning. Although the pictures might seem as though the branches are yellow, they are actually more brown in color. We are watering them with a good 10 minute soak every 4-5 days or so, so we don't think it is a water issue. Also, some of the branches are blackening at the tips - is this due to some kind of fungus? Any advice is appreciated - please help us revive our trees! Thanks!

Ack -- is my Cedar tree dying? Please help!
Comments (1)It's an Arborvitae (Thuja occidentalis) not a cedar (Cedrus). Does look a bit thin, though the foliage that it does have looks reasonably healthy. Hard to diagnose anything useful from the minuscule pic size that this forum allows. Check for the usual suspects like bagworms. Resin...See MoreMy Two Gardenia Trees are Dying Indoors in Wisconsin.

Comments (16)Exactly, try to just keep it alive until you can put it back outside again. Most look like crap by the end of a winter indoors unless they are held in a very warm humid greenhouse with moving air and full sun. If you want hardly an issue at all, as long as the back porch does not get below 40 degrees at anytime. that is where I would put mine making sure not to over water with some supplemental light unless that porch gets lots of daylight and sunlight. When it comes to mine, I would much rather keep them on the colder side to prevent unwanted wilted growth, pests and dropping leaves. I also use mainly fresh water, bottled, or rain water. NOT TAP. No problem. Keep us in the loop please. Spray the leaves often and use a running fan 24/7...See Moreis my oak tree dying? please help!!
Comments (16)I find it hard to believe with that much mulch piled around that tree that the trunk ever saw a weed whacker or lawn mower close enough to do damage to the trunk. The damage is consistent with trees that are planted too deep, having the root flare smothered. Or it might be a mulch volcano, which would produce the same results. Chances are, if he has another tree with the same problem, then both were planted the with the same incorrect planting practices. I didn't read this whole thread but has anyone asked the OA to sweep back the mulch and/or soil to find out where the root flare is? It certainly would be fun to find out.

Comments (10)The roots were coming out of the pot it was in. which is why I moved it to a larger container. It was super happy when I did that in March. Lots of buds and leaves plus new growth. I checked the root ball and it is not root rot. It’s a citrus soil is there a better mix you like? This tree has been outside and has never been an indoor tree. i sprayed with neem because the twigs started going brown and it was not root rot. I did see cobweb s and black spots on the leaves too. Mostly it gets full Sun from about 10-6 or so....See Moreken_adrian Adrian MI cold Z5

9 years agoHi Ken,
Thanks so much for helping me diagnose the problem with our arborvitae trees. Sorry for the delay in my response. I have attached a close-up picture.
We have been watering the trees about twice a week - a gallon or two of water each time. It seemed to be an average CO winter - it snowed on and off. The snow would not last more than a day or two with out melting off. It got below freezing overnight but it would warm up during the day - average days in the 40s and it would get down to 20 or below at night. It seems like the browning started early Spring. It's clay soil, and when we planted them, we dug a hole two times the size of the root ball and mixed fertilized gardening soil in with the clay soil. There is some browning on the side of the plants that face the fence (the south side), but not as much. We are unsure if they were root-bound upon planting - how can you tell? The lawn is not sprayed where the trees are growing. We did not use landscape fabric underneath the stone.
Do you think it's a watering issue? Based on our research, it seems they are either getting too much water (which seems unlikely), not enough water (which might be the case), or some kind of fungus/disease is causing the problem. More recently, we have been watering them more in the past week to see if that helps, yet we aren't seeing a change - or does it take several days for them to green up if that's the problem?
What do you advise we do?
Thanks!!
