September 11, 2020Q.Evergreen Browning
I've an evergreen shaped into several balls. One of the lower balls is turning brown as well as the one below it. I can see some old gardening tape around the stem just where the limb starts. I tried to cut it back as much as possible, but the stem has grown around it. See the 20190911_Evergreen2 picture. The green gardening tape is blurry, but just visible on the stem. I have another evergreen which started to lose a limb and found similar gardening tape. It lost half the foliage on the limb before I found and removed the tape. Unfortunately, I didn't see this one after planting. Probably because it was already overgrown by the plant. Would you suggest I cut into the stem to remove the remainder of the tape?

Certified ExpertA.The dead branches need to be removed up to the branch collar on the main trunk. Will that remove the tape, too? If not, you can try to "repair" the area with the tape after removing it by following the instructions below.

Southern Ontario, CanadaQ.Privacy Plants Option Like Arborvitae
I want to fill the space between ground level deck (not touching ground) and fence with Arborvitae like plant but because there is only 10ft x 3ft space, is there slimmer type of Arborvitae that doesn't grow over 10ft high? What other option do I have if Arborvitae won't work? Thank you

Certified ExpertA.As long as there is enough soil to sustain the tree, it would tolerate the planting. If there is no soil, I would not recommend it. They will not grow, happily, on rocks.
Here is an article that will help you to know what they require in order to be healthy:

Certified ExpertA.Transplant shock is common with these trees. Disease from too much water is another common killer of these trees at the time of transplant.
Unfortunately, your photo did not come through, so I am unable to assess the damage.
Here are some articles that will help, in the meantime:

Certified ExpertA.It can be difficult to find a companion for this one. The Rose of Sharon is a good one to consider for this space, though. Here is an article that will help:
https://www.gardeningknowhow.com/ornamental/shrubs/rose-of-sharon/rose-sharon-companion-plants.htm
You can try other options, but some plants will have a harder time growing near Thuja.

November 9, 2020Q.Can I Mix Wiltpruf And Bobbex?
I’m wondering if I have to apply wiltpruf and bobbex separately to my arborvitae or if I can mix them together and save some time.

Certified ExpertA.Since the products address two different issues, I would not mix them together. However, it may be perfectly safe and effective to do so - I've not found any research at all on whether they work well as a combined mixture. This might be a better question for your garden nursery expert who sells these products or a certified arborist. You may also want to contact your local extension agent with this question:

02474Q.My Arborvitae’s Outer Branches Are Turning Yellow/brown. Is It Due To Drought? Fungus? Anything Else?
I planted 15 arborvitae Thuja Occidental in October of 2020. They did great through Fall and the Winter Season. Since Early March, I have noticed that some parts of the outer trees are turning yellow/brown. I fertilized them Early April. It has been a very try spring so far in Boston but I have watered them regularly (not sure if enough). Please see attached photos. What is the root cause of this problem? is it drought, fungus, or anything else? Should I prune the tree?

Certified ExpertA.Unfortunately, your photos did not come through. I am unable to see the damage. They are very sensitive to overwatering, and that is usually what will cause browning. Make sure that the soil has plenty of time to dry out down to about 2 or 3 inches or so between watering. Water deep in between these mild dry outs.

From here, a fungicide may be necessary. Here is an article that will help you with fungicide use:
