Plastic edging is available in many different types. There are hard plastic edgings and very pliable vinyl or plastic edging. Plastic is used often in many edging projects and there are even some types on the market that only require installing with a rubber mallet. The border for the sake of this article will be a hard plastic that comes in small sections to allow for corners and curves. This type will not look even if installed on a hill.
Step 1: Mark It Out
Mark the area that you will be adding the edging with the chalk line. On curved areas you can use landscape spray or rough in the curve with the pick. You can also use a string and two stakes to keep it straight.
Step 2: Trench It
You will need to dig a trench that is about 2 to 3 inches deep. A pick will work great for this trench because it is so narrow and has spikes on the bottom to keep it in place.
Step 3: Install The Edging
Installing the plastic edging is not difficult. It will come in small 12-inch sections so that you can add just as much or little as you need. It also makes it very easy to make turns when needed. If you are setting curves, attach a few pieces together at one time. There are stake holes for added durability but in super hard soils there is no need to add them. They will be spaced every twelve inches along the length of the edging. Use a rubber mallet to hammer the plastic edging evenly into the ground. You can add one piece at a time as you work along the border or put a couple of pieces together. The will not connect correctly though until they are secure in the ground.
Step 4: Trimming
It will most likely be necessary to trim at least one piece of the edging. A hack saw is the best way to cut this hard plastic.
Step 5: Backfilling The Edging
Use the shovel to backfill the area that was trenched. You will need about a ½ inch of edging to remain above the soil. This helps deter the plants from wandering and hold garden soil in. Tamp down the dirt with the shovel to get all of the air pockets out. Walk along both sides of the edging to tighten the soil and hold the edging more secure.
Plastic edging can be a useful and inexpensive tool for separating two spaces in a yard or garden. It can be used to create paths or define flower beds. It is wonderful for using to help retain mulching products or decorative rocks inside a contained area. Whatever type of edging project that you decide to tackle next the basics will be the same as explained here. Dig, place, secure and backfill—it’s as easy as that.
