How do I effectively sow wildflower seeds on my rooftop?
I’m planning to sow some wildflower seeds on my rooftop, but I’m unsure about the best method to do it. My garden setup has some clay-like soil that dries out quickly, and I'm worried about the seeds not getting enough moisture. I’ve read different techniques, like broadcasting vs. raking them in, but I'm not sure what’s best for my conditions. Have any of you successfully sown wildflower seeds on a rooftop? What techniques did you use, and do you have any tips to ensure good germination?
