Advice on Thuja Green Giant

Posted by ejohndan Northern VA (My Page) on

Hi all,

First of all, I am a novice gardener... So excuse my ignorance.

I moved into my first home last year, and there are a row of Thuja Green Giants. They are only a few years old (maybe 4-5 years at most).

Most of them look great, but there are three on the side that look sickly. I wasn't sure what to do at first, so I waited a year to see if they were dying. Now, 1.5 years later, they seem to be growing (the top shows green shoots). But I don't think they will ever fill out. Thoughts?

I also think I finally found the problem. During the winter and the early spring, when it rains, those three trees are located right in a marshy area where the water flows under the fence (just the natural grade). The other, healthy trees are on slightly higher ground.

Could that be why they look so thin? .

Finally, what should I do? I am not putting in a French drain at this point. Should I take the sickly trees out? And, if I do, what do you all suggest I replace them with? I want a tree that will grow tall enough to screen out that house, but the tree also has to do well with water.

I live in northern Virginia. Here are links to more pics:

I believe there is a Northern White Cedar tree that does well in wetter soils. Perhaps three of them would be suitable replacements. Will see what others suggest.

Thanks Scotjute. Yes, I would be interested in what others have to say.

I looked up that cedar, and on the map it shows it being mostly in Canada or further north. Do you think it will grow well in northern Virginia? It gets hot here in the summer.

Also, I am looking for a tree that grows fast! And also provides great screen. If you look in my photo, you can see that there is a different kind of tree (what is that, an evergreen?) on the right of the thuja giant greens. Those grow real well... I could just put 1-2 of those in to replace the sickly thujas, right?
