I have just found out that I have the bagworms on my cypress trees. The trees are 10 years old and never had a problem. I sprayed the trees yesterday (when I finally realized what was on them) with liquid Sevin. Can you please HELP me with this problem, and can you tell me if they will kill my trees?
Hope you can help me. I just noticed one of my Cypress trees turning brown from top to bottom and these trees are a least 15' or better. They have spread to a few other trees but are not bad. This tree looks like it is done for. Is there any way I can get rid of the bagworms and save this tree?
Have bagworms on my Leyland cypress to the point that trees are turning brown and losing needles. Am trying to prevent remaining trees from becoming infested and hope to save the ones that are. They are presently in the cocoon state, so I have been ABLE TO REMOVE SEVERAL BY PULLING THEM OFF. Cannot reach the rest. Please help. Temperature here right now is near 90 degrees. Is it too late?
I have been told to plant after the first frost. I'm in Buffalo, NY (Zone 5B). It's cold. I am especially concerned with the Hinoki cypress, Chamaecyparis obtusa. Can I use it as a foundation plant? Are the roots destructive or are they shallow?
Yes, this would be an acceptable foundation planting.
I have six blue cypress trees planted around my new house along a wall. They were planted between rose bushes that have grown out of control around the cypress trees. When we cut back the rose bushes (vines), the cypress were very weak. Some are not able to stand straight on their own. How do we go about rejuvenating our cypress trees? They are 8-10 feet tall and their trunks are fairly thin.

The plant can reach a diameter of 20 feet. If the trunks are weak, I suggest a metal T-stake driven in the ground about 8-10 inches from the base of the trunk. Attach the plant to the stake with a non-binding material loosely in 2-3 places. Do not tie too tightly, the plant needs room for growth along with the ability to move slightly in wind andd breezes.
Why is my cypress pom pom turning brown?
There could be several reasons:
Lack of water or too much
Try to identify any changes the plant has incurred before it started turning brown. If you can isolate a "change in lifestyle", you know where to start helping it recover. If you can't find a change, I suggest you take a sample to your local agricultural extension office for identification and recommendations.
Are Leyland cypress related to Arizona cypress trees? Allergy issues involved.
They are only slightly related. The Leyland cypress is a hybrid created from the Monterey cypress (of which the Arizona is closely related to) and Alaskan cedar and does not occur naturally on its own. If you are allergic to Leyland, it could be attributed to the cedar as well, rather than simply the cypress side.
