First, paint the stain onto the handrail then let it dry.
Lean the banister along the wall of the fence where you want it placed, then decide where you want the plants to hang on it before you drill any holes.
Once you've decided, drill a hole at an angle on the bottom side of the railing and then twist in the screw-hook.
Next, drill a hole in the back of your planter and then slip the planter over the edge of the plant hook to hang in place.

DIY Vertical Garden Ideas
This handrail was a simple way for me create a custom garden space for our small backyard, but there are plenty of other unique vertical garden DIY's, too. Keep in mind that you can also use a vertical planter as a twist on the traditional garden for creating a modern herb garden. Here are a few other DIY projects for creating a succulent wall planter or vertical planter —
Repurpose PVC pipes cut in half as plant pots that won't rust
Snag an old wooden pallet that's being thrown out
Coat a large wooden picture frame with polyurethane to make a weather-proof succulent frame
Use a fabric shoe organizer to hang on your patio for growing herbs or succulents as a hanging planter
