Ruchi, what a beautiful walkway! Given the gentle curves, I think in-ground planting might look best. I would start with a list of the foods you’d like to grow and then review their growth habits, light and water requirements. You could also perform a soil test to see if the pH is right. Armed with that information, you could lay out the beds. Incorporating some herbs suited to your locale would also give structure. If you select plants that will need support, a post and cable zigzag might look nice. Good luck!

Thanks for your advice and input Stacey ! Love your attitude and way of thinking!

I might be asking you more as I go along. Look at these pictures from Houzz, this is what I was thinking, tell me if it is worth it.
Also how do I get my soil checked? Do I take a sample somewhere?
