How to Make a Homemade Aerator for Lawns

Lawn aerators foster healthy grass by softening the soil, allowing water to penetrate the ground and giving the roots room to grow. Professional lawn aerators actually pull plugs of soil out of the ground -- a very effective treatment, but it can be costly and it leaves temporary little tubes of dirt on the lawn. Aerating with spikes or large nails works well for do-it-yourselfers with limited budgets; manual aerators may be found as pitchfork-like tools, rollers you push and even spiked shoe attachments. Or, if you have a small lawn, you can make your own for the cost of a few small hardware store items.

Ruler
6-by-12-inch piece of plywood, 3/4 inch thick
Drill
5/64 drill bit
4-inch nails
Hammer
Metal handle
Handle hardware
Philips-head drill bit

Instructions

- 1
  Measure and mark every 2 inches along the long sides of the 6-by-12-inch plywood. Measure in 1.5-inch intervals along the short sides of the plywood.
- 2
  Connect the marks to make a graph on the wood, using the ruler as a straightedge.
- 3
  Place the plywood on a grass or dirt surface. Drill a hole through the plywood at each of the 12 points on the graph where the lines intersect with a 5/64 drill bit.
- 4
  Drive a 4-inch nail into each of the drilled holes with a hammer. The nails will go all the way through the plywood into the ground.
- 5
  Place a metal handle on the board, lining up the screw holes over areas of bare wood. Using the drill with a Philips-head bit, drive the screws into the plywood through the holes to attack the handle.
- 6
  Pull the plywood straight up with the handle. To aerate the lawn, place the homemade aerator on a section of grass, step on it to push it into the ground, and pull it up. Repeat until you've covered the lawn.
