I planted my fall tomatoes in early November. It was very, very late to plant them but the fall was brutally hot, especially in October. I added some Greek and Italian oregano to the elevated bed with my two tomatoes plants. All were growing well with lots of yellow blooms, pretty green tomatoes, and fragrant herb leaves. In January, we experienced a very unexpected and brutal cold front. The temperature dropped below freezing for almost 10 hours, very unusual for the Texas Gulf Coast. I picked the green tomatoes right before the front blew through Rockport and pulled out the tomato plants but left the oregano for many, many deer that hang out next to my condo complex.
After a couple of months, the oregano plants were still in the bed, growing quite well with no nibbles from the deer. Although I am a Master Garden, I don’t remember discussing that some herbs are deer resistant.
(Notice I did not say deer proof. In my opinion, there are zero plants that deer will not eat if they are truly hungry.) There were plenty of plants in and around my patio for the deer to eat plus my neighbors feed them corn occasionally, so I wondered if some herbs were officially or even unofficially deer, and maybe rabbis and squirrel resistant.
I have discovered the following herbs have strong scents and deer tend to not eat them and their presence may deter deer from eating neighboring plants. Bee balm, Chives, Garlic Chives, Lavender, Mint, Oregano, Rosemary, Sage and Thyme.
All of my spring tomato plants have an herbal friend plant nearby. It’s not a guarantee but I will try anything to keep the deer away from munching my plants.
