I have three banana trees - one is blooming, a 45 foot tall mango tree, a Thai-lemon tree, two papaya trees, and a passion fruit vine. We then rotate through various vegetables in other areas.
I want to build the flower bed out front because people from the apartment complex next door have been parking in front of my house and making noise at night. I can call the cops and make them mad at me or I can build a raised bed that they can’t park in. I sort of felt that the raised bed was the better option. I am debating if I should make the bed a bit wider and plant Hibiscus close to the fence and the dwarf gardenias in front. But either way this is a 36 foot long flower bed.
Excellent option, in my opinion, and in addition, to solving the noise problem it will smell heavenly.
Have you thought about some prickly Cactus???
