Wall planters enhance the appearance of the exterior of a house and enable you to grow flowers or foliage at varying eye levels. They dress up a wall and add color to it and allow you to utilize ground space so you can place other containers there. Install a planter under a window, above a doorframe or on any spot on a wall to brighten it up. Fill your planter with different types of flowers for a colorful mix.
Inspect the surface of the wall so you can use appropriate mounting hardware. Use standard lag shields on brick walls, and mounting screws for hollow brick or block walls that will penetrate the mortar to prevent the block from crumbling due to pressure.
Step back to select a suitable spot on the wall to install the planter. Visualize how the planter full of mature plants will look at that spot, or under a window frame. Also keep the size of the mature plants in mind when making the decision, so they have plenty of room to grow taller. Measure and mark the center of the window with a marker.
Step inside the room and locate studs under the window frame with a magnetic or electronic stud finder. Studs are usually found on both sides of the window as well as the center. Mark the location for the studs with a marker. Also extend the marks on the window sill so you can view them easily from outside.
Lift the planter so its center is directly over the mark in the center of the window sill. Also mark locations for both the studs on the back edge of the planter. Use a carpenter's level horizontally against its top to make sure it is even and level with the frame. Make sure the selected spot on the wall has no crevices between bricks. Put the planter back on the ground.
Insert a drill bit the same size as the lag bolts into your drilling machine. Wear protective eyeglasses and earplugs and drill holes over the marks in the back edge of the planter.
Raise the planter again so it rests in the center of the window, and extend a pencil or marker through the holes you just drilled in it on the wall. These marks will be directly over the stud marks.
Drill pilot holes over the marks on the wall and insert the lag bolts into them. Tighten each lag bolt with a wrench so it supports the weight of the planter securely.
