Hi there: each year on my global cedar I get extensive spider webbing on the bush. The other day I saw the spider and tried to capture it, but it got away. It is not spider mite webbing. I have been hand picking it away. Is there anything else I can do. Thanks so much
Thank-you for contacting Toronto Master Gardeners with your question.
In general, spiders are beneficial insects in the garden because they are predators and they control other insect pest populations. While they are not harming your cedar, they are obviously enjoying the protective cover it offers, and the webbing can become unsightly. Picking off the webbing (as you have been doing) or applying a hard spray of water can offer temporary relief but the spiders will rebuild their webs if the site is appealing to them.
