have you ever had a soil test???

contact your county Ag or soil conservation district.. and ask them how to have a soil test done

the brown ones dont look that great in the pix ...

the green are fine ....

they arent all that foo foo a plant.. and i am surprised how much trouble you are having.. and if you plant roots down.. you ought to be up near 80% success.. hence the soil test suggestion..

your soil conservation district might also have better ideas for Arb-like plants for your specific area ... they may have just had their annual spring sale.. or you might be just in time.. if they have left overs ....

good luck

I am experiencing the EXACT same thing! We planted 55 of these along our property line and they all bronzed. Please let me know if you find a fix.

Thanks!

I've got several GG's up on my land, which is either Z4 or 5, depending on which USDA hardiness zone map edition you are looking at. The importaant factor, I believe, in where mine are planted is that it is a very exposed site, not down by the woods, but right out in the open field area. They have burnt up quite badly. Since we're so far north where I'm talking about, there is no new growth yet to indicate where these plants are at health-wise. I still think they're going to come around, but I can't be sure just yet.

An interesting contrast lies between these hybrid GG's and the native Thuja occidentalis that makes up a major component of my woods. The latter went through the cold, snowy winter just fine....never lost their green coloration. I may be finding out that this area, where my land is, is just too harsh for GG's. If so, so be it. I've got plenty of other great conifers, both native and introduced, that are or will be thriving there. I'm also thinking that it would be interesting to plant a few GG's in more sheltered locations in the woods clearings.

I'm experiencing the same thing with my GGs which I planted last June. Although, they look more closely like the second picture. Half of the tree is bronzing to brown color with light green/yellow tips, and half is green/light green.

When I inspected them this week, I noticed that most of them are producing the green bluish seeds on top half of the plants. Does this mean they will just shed the dying parts and recover eventually?

I was skeptical when I saw them early spring but since they are producing seeds, I'm hoping they will begin to liven up. I gave them a good watering this week and the weather's been pretty nice for plants. I'm keeping my fingers crossed.

have any of you HARDENED them off to full sun application ....

IF THEY CAME FROM A GREENHOUSE/shadehouse ... perhaps they are burning up.. because you blasted them out to full blistering sun????

when i order conifers.. i always try to remember to ask upon order.. or call them back when i get them.. to ask if they came from a greenhouse ...

the next question would be how your zone compare between yours and where they are shipped from ... if they are growing lushly in z8 .. and you plant them asap in z4 in very early spring ... again.. there might be hardening off issues .... but to temps this time ....

just speculating ...

the grafters in WA and OR... tend to leave them outdoors the second winter.. or what they call winter.. lol ...

but GG's are a rooted plant ... and it wouldnt surprise me if they are in green or shade houses ....

My mistake. What I meant from my post was that my GGs resemble that of the last photo, and not the 2nd.

I ordered mine through Ebay from a seller from Texas at 2 feet tall and planted them last June and most grew at least 6 inches and about 3 grew about a foot. The long winter in Southeastern Wisconsin must have contributed to the browning I think. I made it a habit to water them thru fall and were looking great until January when the wind chills were brutally cold (-41) and temp was -21.

I really hope they will recover this summer.

so how are they looking 2 months later? pictures would be great too!!!

Thuja Green Giants are easily "wind burnt" which will turn them totally brown in the winter but they will green up in the summer. I have some that a re sporadically turning/dying from the summer heat. I havn't a clue as too why? It's about one out of 8 at my place......

I just planted 8 G G trees. I have a drip line. I used a little holly tone. I live in zone 7 . I planted them in the begining of may or very end of april. They are all turning alottle brown in areas. I water them for 7 hours straight one day a week. I have mulch around each and on top of the drip line hose. What am i doing wrong. Why are some turning brown.

Sorry to hear about everyone's problems growing GG. On my property in St. Louis, they seem incapable of being killed. I've dumped them in the ground in the heat of summer, then decided to move them the following year, broke half their roots in the process, and utterly abused them, and the things just keep on going....

I think maybe they just like my backyard..

planting in z7 should have been done a couple three months back ...

browning problems could start with the wholesaler.. thru retailer.. thru your transport .. transplanting and aftercare ..

as to which of those variables is the problem... i know not which ...

deep thorough watering throughout the root mass is imperative.. are you doing that??

We planted 10 thuja in August and since then some turned brown right away and others are on their way. They moved into a very sunny stretch in our yard and we had several weeks of hot sun here in northern CA (menlo park). I'm curious for those that had the browning whether the thuja eventually recovered or whether they needed to be replaced? Also did anyone come to a conclusion as to what was the cause?

hey sue.. you should start your own post..

give us a few pix ...

describe how you planted them ... but i have to tell you.. august is rarely a great planting time ... in many locations.. its what i call.. the heat of the summer ...

and clearly indicate if they are thuja or green giants ...

Thx Ken! I will look into my own post too, meanwhile to answer here, yes - they are definitely thuja and attached are some photos, you can see some already turned completely bronze, some seem to be on their way. Is it possible for them to recover? Do I need to do anything specific for them in the meantime? Or just wait till spring? Of the 10 we planted, 4 have turned brown/bronze, and 2 or 3 seem to be thinking about it.

Thx! Suzan
