I know it has been discussed before, but I felt a need to dredge it up again. I'm getting sick and tired of seeing that green metal edging thrown in peoples landscapes. For the most part we do just a natural transition between the grass and the mulch, but lately we've had people asking for a definite edge. I'm not looking to curbing as a business, but as an additional service we can do in house. What are your thoughts on the product as a whole, certain types of machines and the like? I have seen that there are companies that are offering "cable" units that install a cable into the curb....is it worth it? Basically, I'm looking for any and all information. I know for a fact that I don't want to buy (new) into one of these companies snake-oil marketing and equipment plans. FWIW, we service a market that does not really know about this product. Thanks!
