Use Super-Sized Planters: Buy several large planters and fill them with tall, decorative grasses or flowers. Arrange the planters in a row along a section of your porch or other area where you need a little screening.
Plant Trees Along Your Property: If you have a bigger yard (and budget), consider this evergreen privacy fence idea. Trees and bushes make great fences, so long as you’re a little patient. Fast-growing trees, such as arborvitaes, can reach any desired height within a few years, leaving you with a natural barrier between your backyard and your neighbor’s.
Build a Living Wall: You can make a simple living wall by hanging several flower boxes from a lattice screen or other frame. Fill the boxes with soil and the greenery of your choice. For the most coverage, choose larger, bushy plants as the main occupants of your boxes.
Hang Outdoor Curtains Around Your Patio: Simply hang the outdoor curtains of your choice from a rope, wire or rods around your porch, patio or other seating area. You can use trees, porch railings and any other sturdy fixtures in your yard to hang your curtains.
Buy a Retractable Backyard Screen: It may not be a DIY backyard privacy solution, but it is a relatively quick and cheap way to put a wall between you and any prying eyes. You can find backyard dividers and screens for sale in practically any home improvement store, both in real life and online.
Build a Privacy Screen: You can make a quirky, yet functional, privacy screen out of a few old doors, either painted to match or left in their original color. Simply attach each one together using hinges to form a folding screen.
Put Up a Simple Lattice Fence: All this project takes are a few wooden posts or boards, depending on how sturdy you want your fence to be, and enough lattice to cover them. Before putting the fence together, you can also easily paint or stain the lattice to complement the color of your house or yard furnishings.
