For anyone wanting to repel cats from their gardens, black pepper works. I use it on my indoor plants because it is too expensive for outdoor use. Cayenne is not so expensive and might help also. I love watching gardening videos. Some of my favorites are Self Sufficient Me, he is down under in Australia. Black Gumbo is in Louisiana. Charles Dowding is in the UK. I sometimes watch a few others part time. Even if you don't live in their part of the world, they still have a lot of good ideas. I have tried propigating roses, with limited success. I do have one rose bush that made it and have had it for a long time now. It is from a burgundy tea rose, but I do not know what cultivar. It was mislabeled when I bought it, and somehow I have another identical one that I bought and misplaced the tag. A few others did take, but later died off. I saw where some stick rose cuttings in a raw potato, and want to try that and see how it goes. I have some pear tree cuttings I am trying to root. This is the second year I have tried that. The first ones did not take.
Well in our area the birds seem to call the cats for miles. I quit feeding the birds in spring/summers and have less cat issues. It’s a conundrum really. Cats help with mice and other ground critters but also are a major issue for the birds , unfortunately. Put Plantskyyd down to keep cats away and other ground critters , deer and gophers.it works great. I plan on putting bird food out for winter soon in areas with shelter from rain. I see they are out now in sunny days searching for food. Cats don’t like to get wet..birds should be ok in winter . I remember seeing the rose cuttings placed in potatoes . I suppose it will be better than a root cutting in water which can rot. I think it depends on the time of year the cutting is taken . Rose cutting better taken later in fall has a better chance of taking. Also in many cases it helps to dip cuttings in root hormone the place in sterile soil , or make your own root hormone by soaking willow bark in water . soil temperature is important 67-70 degrees, some prefer darkness until they root while others require light to root.
