Thuja trees, known for their distinctive flat leaves, are a fast-growing arborvitae tree and shrub that can solve various garden problems. They can be planted as privacy hedges, hiding ugly fences or walls, or to create a decorative feature. Thuja trees are easy to grow and require minimal care, as they are hardy and low-maintenance plants. They are tolerant of various weather conditions and pests, including deer. To prevent common issues like browning, it is essential to water properly and feed with a liquid fertiliser. Most Thuja cultivars under three years of age will thrive if watered every other day.
Soil is crucial for Thuja plants, with an ideal pH between 6.0 and 8.0. Young Thujas don’t require winter protection once established, but they should be watered abundantly and mulched to retain moisture. Watering Thujas three times a month during the summer months and twice a month during the colder months is recommended. Thuja trees prefer well-drained soil and full sunlight, but may struggle in extremely hot or dry conditions.
When planting in the ground, mulch with organic matter to retain moisture and provide slow-release fertility. Thuja trees grow well in partial to full sunlight, ensuring they receive at least 6 hours of sunlight daily for optimal growth. By following these essential tips, you can ensure your Thuja trees thrive and enjoy the benefits of their unique beauty.

📹 Emerald Green Arborvitae Care: Tips, Removing Brown Needles, Fertilizing, Privacy Tree Fence
Removing the dead needles inside of these Arborvitaes will help with air circulation and prevent disease. I give some tips on …
We were recommended to use a fertilizer especially for trees, shrubs and evergreens. Manure is also used in addition to the fertilizer. We mulched them too. They are already looking better than this Spring. We had a lot of snow and they had separated, we tied a few limbs. It worked great and now they look normal. But I will go clean out the dead bit. Thanks for showing this, I wasn’t sure if I should.
Excellent article! I just fertilized our 14 arborvitaes with Plant-Tone. I will be spraying with Captain Jack’s in a few weeks. We really learn as we age! I remember seeing those bag worm cocoons years ago on another property we owned. Not knowing any better; I thought they were dead pine needles. Almost all of our Spartan Junipers were decimated. You live and you learn. Thank you!
Thank you so very much for the tips and for showing the amount of fertilizer I need to use for them. I love this trees and I had planted a bunch of them. Last year I have the problem of bag worms which I never had before and I was looking on how to prevent them and I found you to give me these great tips ❤. Thank you 🙏 for so a nice and very simple article without so much talking but straight to the topic👍👍
I bought 7 thuja arborvitae early spring. It is 7/21 and I still don’t have them planted. We put in a fence that took longer than expected and we wanted to get it stained before planting up. Plan on planting them up even though we are in a drought because I think they’d be better in the ground than in the nursery containers. We have about 50 established arborvitaes on the other side of our property and every spring we spray for spider mites along with our weeping junipers. My neighborhood was built in the late 60’s early 70’s and about every other house has a weeping juniper and I noticed in early summer they would all start to turn brown. Had a arborists come and he told me it was a spider mite problem. Since I started treating I am the only house that has a beautiful bluish green weeping juniper in the summer months for the last 7 years. My neighbor across the street just asked how I am keeping it green because he said he waters all the time. So now he is treating his yard.
Thank you for your article! Spent the last three days all day doing just this which you are doing in your article . My neighbors think I’m crazy for sure ! There are brown rows of arborvitae all over town and why spend the money if you are just going to let them turn brown and die. Mine are about 7-8 feet and newly planted(10 large from a local nursery and were robust ) and, were very lush until about 3 weeks ago they started to (and did !) turn brown all from the middle out. I didn’t even notice because I wasn’t out there enough and am now alarmed. I figure it is transplant shock as I don’t see any bugs or yellow at the top. 8 more are also small(5 feet and skinny ) or possible they got too much water with all the rain and the strange storm we got a month ago with high winds .leaf blight maybe … I have a guarantee for a year but know how that might play out ., there is new growth that is dead on the inside of sone and tiny new growth that is bright green and definitely alive on all of them; some more than others . I am about to fertilize and wondering about the Biotone and drenching them or not. It’s making me crazy ! You are great I loved your article !!
Thank you for this article. We have a group of 10 pretty mature/tall arborvitae in our backyard — over 10 feet tall. One got bagworm last spring/summer. I caught it around August/September and tried to get them all. But since our AV are so tall, it was hard to collect all of them. Now that we’ve made it through winter, I’ve sprayed my AV with Bacillus Thuringiensis to counteract any remaining bagworm issues — I also removed some more this weekend. This particular AV is brown near the top and still green in the middle/on the bottom. I hope I can save it. Next week, I am going to put down some Plant Tone and, thanks to this article, remove the dead needles in the middle. Any other tips/recommendations to try and save my infected AV? My other AVs seem to be in pretty good shape, so hoping these treatments will serve as preventive maintenance. And another question: when the needles fall to the ground, how do you remove them — just pick them up or blow them out with a leaf blower?
Thank you for the informative article. I just( last week) had some Arborvitae 3 ft shrubs planted. ZONE 7b. Western North Carolina Winston Salem area. How often should I water them. About how many gallons of water per tree.? I do not mind the extra work. How do I protect the leaders from the wind and very cold Temps. (temp range ????). Thank you.
We recently planted 11 of these a month ago. They were at Lowes and very dry at the time we bought them. I’ve been trying to water them but not when I think it’s going to rain. I have started seeing some brown areas (outside of the tree). They weren’t like this when we bought them even though they were very dry. We did have dead leaves to fall from the dryness but they weren’t brown on the outsides. Do you think they are not getting enough water? I’m getting concerned that they will die. I am also in zone 7-near Greensboro NC. Should I cut off the dead areas? I don’t think it’s the whole limb just some leaves that are noticeable on the outside when you look at the tree. I am new at getting these types of trees. Thank you for this article
