Hi Brooke, 

Thank you for your question about raised garden beds. As you may have noted in the OSU Extension publication “Raised bed gardening” a variety of materials can be used for building raised beds. https://catalog.extension.oregonstate.edu/fs270. 

Oregon State University has done research on the new type of pressure treated lumber and found it is safe for use for vegetable gardening. The original pressure treated lumber used arsenic as one of the components for pressure treating. The new (since 2004) pressure treatment Alkaline Copper Quaternary (ACQ) is safe for use in raised beds. Here is the link to an OSU publication that discusses ACQ pressure treated lumber in raised beds. http://extension.oregonstate.edu/question-of-the-week/raised-bed-lumber-pressure-treated-safe.

As you noted, redwood and cedar are good choices for raised beds, however, are more expensive. Untreated pine is an option, though as you stated, will not last as long. You may find the following publication on materials for building raised beds of interest: https://extension.umd.edu/hgic/topics/materials-building-raised-beds 

The OSU Extension publication on Vegetable Gardening has a section on raised bed gardening that you may find helpful: https://catalog.extension.oregonstate.edu/em9128 

Regarding your question about constructing deer fencing, following is a good summary article:  https://pss.uvm.edu/ppp/articles/deerfences.html 

The Oregon Department of Fish and Wildlife makes the following recommendations:

There are a variety of options for deer resistant plants. Following is a link to aromatic herbs that are considered deer resistant: https://extension.oregonstate.edu/news/herbs-rescue-fend-deer-aromatic-plants
