THE PATH-MAKING MISTAKES I MADE THAT YOU SHOULDN'T

One thing that can be said for sort of tedious gardening tasks such as weeding or moving mass quantities of soil is that it gives you a lot of time to think. And over the last several weekends of working in the oval circle garden I've spent a lot of time reflecting on the mistakes I made there.

It was the first garden I designed from scratch so I give myself a big pass on a lot of things that went wrong there. It was also the first time I built paths, and more than anything else that I've learned from my mistakes in that garden, I learned a lot about how not to build paths.

So I'm going to save you from the anguish of a poorly constructed garden path and tell you exactly what you SHOULDN'T do.

The oval circle garden was cursed with poor design decisions from the get-go. The 16-paths were way too small and oddly curved when they didn't need to be.

1. DON'T SKIMP ON THE SIZE

This is a relatively small garden and when I created it, I was concerned I wouldn't have enough room for plants, so downsized the paths, to a paltry 16 inches wide. I suspect that I was also trying to save some money on the hardscaping. In general, a path meant for one person should be a minimum of 24 inches wide. If two people are meant to walk together or it's a longer path, go wider: 4 feet at a minimum.

Skinny paths not only just feel wrong, they also look wrong and nothing else will feel right when the hardscaping sets the wrong tone.

2. DON'T CURVE FOR NO REASON
I'm a sucker for meandering curves on a path, but they should make sense. The path should curve because it has to to get around an obstruction. When I made the path to the garage, I installed gardens that forced the path to curve, which might be cheating, but it's a chicken and egg thing. When I did the paths in the original oval circle garden, I thought that curved paths would keep it from being too formal. For two of the three, it worked, partly because the curve was gentle enough that you could still walk straight. But the third path had an odd, too-sharp curve in it that was all wrong.

This is the remnants of the landscape fabric I pulled out of the garden. Yuck.

3. NEVER, EVER USE LANDSCAPE FABRIC

Some people are going to think this advice is crazy. In fact, the internet thinks this advice is crazy. If you do a Google search for how to build a path, nine times out of 10, the instructions will tell you to put down landscaping fabric. And yet, many landscape professionals never put it down.

Landscape fabric is great for a year, maybe two. You'll be applauding how well it has kept weeds out of your paths. But paths, especially gravel paths, get dirty. Soil falls in, blows in or is tracked in and then is trapped on top of the fabric. This creates an environment that is very hospitable to nasty little weed seeds, which sprout. And unless you are a gardener out there every other day on your hands and knees pulling all these little sprouts (you're not), they get away from you. And then they send down roots THROUGH the landscape fabric, which makes it impossible to pull them out. Worse yet, it has a way of emerging in places you don't want it to.

A wild violet was one of many weeds embedded in the landscape fabric when I pulled it out. The roots extended underneath and were also intertwined in the fabric itself. DON'T DO IT!

Then, when you finally decide you just want to get rid of the damn fabric, you can't pull it up because you've got gravel or stone on top of it.

For the new paths, I plan to take the same approach that I did when I built the path to the garage. I'll lay down a couple inches of compacted paver base (finally crushed stone), which is in itself an inhospitable place for anything to grow. Then I'll lay down a couple inches of gravel on top of it. Yes, soil will still get in there, but when weeds do show up, I'll be able to dig them out properly, or, even better, hit them with the weed torch with no fear of lighting a giant chunk of landscape fabric on which I may be standing on fire.

Friends don't let friends use landscape fabric. Be a good friend.

Once I removed most of the pea gravel, the metal edging was still in place, but you can see that the soil was backfilled right up to the top edge of it. This just meant more soil crept over the edge into the gravel. 

4. DON'T DISRESPECT YOUR EDGES
When I made the paths on this garden the first time, I installed metal edging, although this same mistake can be made with every other kind of edging. Back then, I backfilled soil right up to the top of the edging. Then, on the other side, I backfilled gravel damn near to the top. As you can imagine, there was plenty of soil that ended up in the gravel and vice versa. Keep materials below the top of edging to make sure they stay where they should.

With the gravel dug out, even though I backfilled too high on the metal edging, 13 or more years after I installed the metal edging, you can see that it was still doing it's job (there's still some on the right side of the path) before I pulled it out.

AND ONE DO

There are a lot of options for edging materials to divide a path from the grass or a garden, but I've been thrilled with how metal edging has worked out. Generally, I prefer steel over aluminum and a 4-inch tall edge over a less expensive 3-inch edge. It can make a perfectly straight path or a curved path with no breaks. Because it is so thin, dark colors such as black and brown blend in well. Unfinished steel edging will gradually rust which is a lovely affect as well.

Of course this comes at a price. It's not cheap and shipping can cost more than the edging itself. I was all set to order this edging until I found out it would cost about $150 (more than the cost of the edging) to get to my house. Fortunately it turns out that Lowe's has the same edging in a slightly shorter size so I can drive to store and get it.

Even though it's not cheap, at least when compared to plastic edging (no, no, no) or bender board, it's still on par with or less than any kind of stone treatment. And it's certainly easier and faster to install, all of which makes using metal edging a big DO for me.
