We just purchased 27 Thuja to plant along our property line to block the farm and hopefully prevent the Texas long horns from continuing to come over on our property. What are the chances they will like to eat the Thuja? If they do, what type of fencing could we buy to block the trees from them until the Thuja get bigger.
Deer love Thuja occidentalis. Cattle or other animals that are walking through an area already are liable to keep walking through it after a planting is installed. The new plants will lose in this kind of situation. What you need is secure and effective fencing. A feed store/farmer's co-op should have suitable products or information about getting them.
Have had some browsing by deer of a few native T. plicata among many on Island County, WA site. The only thing completely predictable about deer in the garden is that you have to fence them out to be sure of escaping their attentions.
Also use electric fencing to stop cattle. If you already have a fence you can attach it to the top and off set into their paddock. It needs to be a strong one not battery for cattle. They will love your hedge. For some reason cypressy ones are like chocolate ice cream. Liz
