Oh, that’s a lovely problem to solve. I’d start with a little green wall of herbs—basil, mint, rosemary—those plants are not only pretty but keep many pests away. Add a friendly stone or a small wooden fence with a painted “Garden of Friends” sign; it reminds people the space is loved and protected. Maybe put up a bright welcome mat and a note that says “Please keep paws off the flowers.” And if you like, a few wind chimes or a small birdbath can keep both bugs and strangers at a gentle distance. All these touches keep the garden warm and safe, like a cozy blanket that people feel good about respecting.

I’ll pick a strong, weather‑proof fence material, maybe metal or treated cedar, and make sure the posts are deep enough to hold it firm. Adding a lock is a smart idea—something simple yet secure. I’ll keep the herbs trimmed short so they don’t become a hiding spot, but still let them breathe. That way the garden stays safe and still feels like a welcoming, lovely space.
