I've used the black foam and it is a pain to work with. If you use it, be sure to wear old clothing and rubber gloves. Then plan on using twice as much as you expected. The things I like about the foam is that it's still there after ten years. I think it will be there after a hundred years. You can also pull the liner apart from the stones without harming the liner. I've rearranged my waterfall a few times and never had trouble pulling it apart. I've also used construction adhesive to secure some of the stones in my waterfall and I needed a large pry-bar to get that apart.

Wow, it's a small world (or internet in this case). I don't keep up with the conifer forum as well as I do some of the other forums, so I didn't realize this thread was a spin off of another one, but it's still a good idea to have the link to the above article as a reference for any future searches. I agree with Ken, that frequent replanting would go a long way towards solving the issues relating to soil decomposition, except for four things. First, even if you change your soil every other year, most soils will still have some drainage deterioration towards the end of the two year period. Second, if you use your old soil and mix it back in as many people do, that has the potential to cause problems. Third, it's good for everyone to understand how drainage works so that they are better able to decide what ingredients are best for particular plants or circumstances. Different species have different moisture and drainage requirements, and different circumstances (climate, amount of supplemental watering available, etc) require adjustment. Fourth, and maybe most importantly, many people (we know who we are) won't replant frequently enough even though this would be best. As for drainage, as it applies to container culture, being vastly different from drainage, as it applies to in-ground plantings, I'm not so sure. The physics is the same! Only the variable, or circumstances, change. A true understanding of one is a true understanding of both.

The client who has the lower rate probably won't be asking -- you might raise that rate, too. If the client with the higher rate was a referral, chances are the friend revealed your rate, which you'll find out if you quote a different (higher, but not a lot higher) one. So you can explain your rates go up periodically, and then, say, describe your recent continuing education or professional honors etc. -- some specialized thing that makes you different from other fine gardeners. (I've observed colleagues leverage high-profile volunteer gigs this way -- the pro bono stuff gets them name recognition, which gets them more referrals, which enables them to charge more...) If the client with a higher rate happens to have a good friend who is one of your other clients, same thing: rates go up periodically, they're still getting a good deal because (cite your skills, knowledge, etc.) and (cite your projects, pro bonos, awards, etc.). Jobs are different, too. I've charged more for steep gardens with poison oak (where I sprained an ankle on the loose steps) than for level sites where it was easier to haul things around. I've heard the same kind of anecdote as INK, where someone tries to set the price too high to force the client to say no, and instead gets the job. The one I heard was a photog, tired of traveling, who quoted what he thought was an absurdly high rate for an annual report for a bank in Asia. The bank had wanted a conservative, dull report, with photos of the suits. The photog said, if I were to do this, I'd take pix of the people in native costumes at specified sites all over the country, and not only my high rate but also first-class travel and accommodations and a big expense account. On the one hand, he was thinking, this would make it worth doing and be sort of a vacation, but on the other he went so overboard that he thought, there's no way they'd go for this. They did. (One of Rick "Day in the Life of..." Smolan's stories.) The art is to set your rate so you can be selective and do mostly jobs you love for people you like.

After a week of the installer being busy when we were available and us being busy when he was available we finally got the preslope fixed and liner installed. Flood testing currently 20 hrs in and holding water! Now I'm stuck once again. I can not find lath for the curb in town. Lowes points me to chicken wire in the gardening section. DH had to go to OKC recently and stopped at HD and bought this http://m.homedepot.com/p/--2.5%20METAL%20LATH/202093395 But installer says its wrong stuff. What exactly am I looking for? Can anyone link me to the right stuff via HD or Lowes website?!
