Use large pavers and river rocks to create a sleek, durable walkway you won’t have to spend time maintaining. Here’s how to do it: First, establish and mark your walkway’s perimeter. Do your best to make the boundary lines straight and exact. Lay your large pavers, aiming to create evenly-spaced columns and rows. Finally, fill the remaining space inside your outer perimeter with river rocks.
this is way, wayyyyyy cool for ANY garden...not just in the tropics. I made one in concrete but this is MUCH easier and less stressful as there is no immediate rush to finish before the concrete sets up. Would HIGHLY recommend to anyone who likes 'different than the norm'........and appreciates a good project as well as the kudos that go with it!
