Presuming your location experiences significant (more than 1 or 2) freeze/thaw cycles over winter, perennials and trees/shrubs need root protection at a minimum, and also anti-dessication measures if conditions are really bad.
I’ve used large bubble-wrap around big pots/containers, followed by aesthetically-pleasing wraps of either burlap or duck…[Read more]

I second the recommendation for Chip Sullivan’s book. Absolutely wonderful, inspirational, informative, etc.

I agree, great and fair price– I for one grow weary of $60.00-125.00 scholarly or technically-oriented books, I think the price is outrageous in most cases.

You may wish to refer to two sources:

A Field Guide to Eastern Trees (Peterson Field Guides)

and also Michael Dirr’s Manual of Woody Landscape Plants : Their Identification, Ornamental Characteristics, Culture, Propagation and Uses

While the latter deals more with cultivated varieties of ornamental trees & shrubs, shade trees and native species…[Read more]

Oh you’re welcome, and yes that’s the idea. It’s used heavily in grass applications because the blades have no problem finding their way through. Plant plugs or even larger plants can be installed through the blanket by cutting an ‘X’ shaped incision in the blanket, pulling the flaps back, planting in, and then replacing the flaps around the…[Read more]

Hi Jenny, I have to suggest Curlex Erosion Control Blanket, it’s manufactured in a variety of specifications but the basic ingredient is aspen fibers woven into a non-directional matrix.

Thanks for your thoughts, Trace One, I’ll have more to say a bit later but I wanted to point out the gentleman being interviewed indicated a vehicular traffic volume of around 22,000 per day, plus bikes and pedestrians. To me that does not seem like low volume but I’m no expert!

Could I ask for an example of what you’re describing here? Thanks!

That’s very interesting, I don’t see how pointing out the fact that you were engaging in the very behavior you condemn is a ‘stretch’, however I am very open to an explanation supporting that assertion.

I find it interesting that when this fact is pointed out to you suddenly ‘everyone is entitled to their opinion’, which is very different that…[Read more]

I can certainly appreciate that irritation. I think it’s interesting and just a little sad that, between 2 people:

One who takes money to teach graphic design and then spends an inordinate amount of time proselytizing– when there is absolutely no indication anywhere in any of the descriptions about the classes that such activities take…[Read more]

“Licensing authorities are set up for one reason: to protect the public from individuals doing stuff they shouldn’t be doing…either through malfeasance or lack of competence.”

No, I’m sorry I don’t think that’s true.

Hi Philip,

May I ask about the first step in your proposed design, that being directing stormwater into vegetated areas before its collected? What are you hoping to filter?

Slightly off topic, but if the owner/admin of the Google newsgroup L.A.R.E. is present, I was banned from it when I posted an alert that several posts were obviously being sent from hijacked accounts, and the contents held a malicious website address. Can we talk, please? Or, if you’re a member of that newsgroup, I would appreciate it if you would…[Read more]

Not sure if this system is appropriate without more information on your program elements, however I’ve had good luck with Invisible Structures, Inc. , specifically GrassPave and GravelPave.

Of course choosing appropriate shade trees which can tolerate compaction is important– American Elm for example.
