Great video as always. I appreciate your videos. You have helped me grow 5 dragon fruit plants in Michigan Zone 6A. I have not had a gopher in two years. Someone on KZbin had a great idea that worked extremely well. He said buy 15 minute road flares. I bought 5 and put them in the holes. My backyard smoked everywhere. It actually worked. I have more just waiting, but so far only one time I had to treat for those critters. Good Luck
