About a month ago, I posted regarding a possible squirrel solution. They were digging in my succulent plants. I tried chili powder and black pepper which worked for about a week. Not in character for us here in sunny CA, it has rained about four times. Anyways, to make a long story longer, I finally figured out about a week ago, the squirrels leave the cactus plants alone. So, I have started putting thorny cacti in all my pots. Luckily, here, I think both succulents and cacti need about the same amount of water so I hope all ends well. I am not going to cater to them by leaving out water or nuts. We are over-run as it is now. Any other suggestions?
