Thuja Green Giant Inquiry

Zone 08755 | Thuja89 added on February 9, 2020 | Answered

Hey, was messaging you on Instagram and you told me to send pics here. Here are my Thujas (have 89 of em) and was wondering if you could tell me if they look healthy. They\'re getting great sunlight and water from rain. And I was told winter makes them turn colors so just getting a little nervous. Some leaves here and there look dried out so also wondering if that\'s normal. Thanks so much!

We talked, earlier in the year, about how overwatering will take a toll on the trees. This, likely, has to do with the issue that you were having at that time.

Overwatering will cause root rot, paired with the time of planting you can expect a lot of this damage. This is something that needs to be corrected, immediately, though. It will result in the loss of the trees, as it spreads quickly from one to the next.

You will need some heavier fungicides, and to test the soil's pH, and nutrient levels.

A pH meter, and an EC (electrical conductivity) meter will help you here. If you are unfamiliar with how to use them, I would recommend having someone from your local extension come out and test your soil for you.

Likely, they will recommend a fungicide, first.
