Why don't you try doing it yourself. Just make the forms, it can't be rocket science.

From Googling cost of concrete curbing/edging...
In central California - Selling Price Of Curbing Is 7 Per Foot. Material Cost Is Less Than 10%, Direct Labor Is Approximately 33%. Gross Margin Is Well Over 50%. Average Job Is 1500. Installations Can Usually Be Done In One Day.

And from a company somewhere in Pennsylvania..."The amount of site preparation needed for a particular job may affect the final price. The price range for landscape border is $5.00 to $12.00 per linear foot."

Calling and inquiring or having someone local come out to give you an estimate on continuous extruded concrete edging is, I know, the obvious solution. But from reading a couple of websites - the company would have to look at your terrain, be aware of impediments, in-ground sprinkler systems, etc. and working around/through obstacles would add cost.

Last time I had it done it was around $3.50 a foot installed. I also did some myself and wouldn't probably do it again. I have both mower edge and normal. For the price, quality, and the one day installation, I wouldn't hastle with it especially if you have a lot to do.

Here's a pic with mower edge on one side of a walk and standard on the other. Sorry it's not a better close up.

Edging notwithstanding - great looking peonies, boxofrox! (I knew there was a reason I'll be adding more this season.)

Gee thanks dib4, I just added a new one to that grouping that is two tone with both those colors. I planted it to the right. I can't wait to see it bloom for the first time.

Thank you all for the feedback and the bonus of the beautiful peonies.

You're welcome mustangs, good luck with your curbing. I know that some don't like curbing and prefer form over function but for me the function outweighs the form. It crisply separates bed from lawn or bed from walk in a low maintenance way.

I started my project 5 years ago with a pond, a rock garden, and a block wall. The rocks and the wall were structural elements to hold up a hillside. Year two, I took this picture of stairs down to the curbed lawn and walkway. I chose the curb because this is on hard pan and I had to load good soil into both lawn and bed and didn't want the edging moving. Now beginning year 6, the old deck and stairs are gone. There's a new deck with sun room and hot tub below with stairs that angle down with the wall. There's a walk with red paver steps and grey gravel and all the beds are full of plants. But the curb still lives on, cleanly separating hard from soft. You can see that first peony I planted behind that old red chair. The regular curb borders the walk all the way around the lawn till it meets the walk on the other side where that other pick was taken. All told I suppose I have between 3-400' of it.

I ended up with over 100' at $5 @ foot. I am pleased with the functionality and from the street, it blends in with the house so it isn't obvious-which was my goal.

Thanks for your input.
