If you are getting ready to plant any type of garden this year, one of the best ways to protect your new investment is by digging a trench around the garden bed.
Digging a garden trench will help prevent unwanted weeds or other types of grasses from invading the new space and will help to create a more finished look to your garden. Other than a spade, you will need very few tools to complete this DIY project.
- Spade (for this project, a half-moon edger is recommended)
- Gardening shears
- Garden trowel
- Twine or marker paint (to mark the trench)
To Dig the Trench
- Mark out the area around the garden bed where you want to dig the trench. This will help ensure you keep the trench straight and do not make any mistakes when you are actually digging.
- Dig your spade into the ground about two inches in front of the marked line about six inches deep. The spade should be angled so the middle of the trench is directly under your marking line.
- Repeat this process all the way round the marking.
- Now repeat the process on the other side of the marking line. You should have a V-shaped wedge in the ground that will now measure 4” wide x 6” deep all the way around the bed.
- To give the trench a more finished look, trim the grass around the trench with gardening shears.
- After you have trimmed the grass, use a garden trowel to pack the dirt in the trench so the walls are not crumbing.
Now that the trench is dug, you will need to maintain it so it always has that finished look. Debris will more than likely gather in the trench, especially during the fall, so make sure clean it out every so often.
You should also make a habit of trimming the grass around the trench whenever you usually cut your lawn to it maintains that finished look.
