Mulchy Christmas to All

by Nate Downey

In this season of giving, we're happy to announce another free tool at http://www.permadesign.com In ad.dtion to being able to estimate the annual runoff from surfaces on your site, now, you can calculate the mulch you'll need for a given project. Here's a screen shot of the more remote parts of the Marin Center and some neighboring easements in San Rafael, CA. Every year, it's the site of the wild and thoughtful Bioneers conference.

We have the tool set to a three-inch depth. In some cases, e.g., when you are sowing seed, you will want to use only a half-inch depth of mulch. Since there are six half-inches in three inches, take the number you get from our caculator and divide it by six. In other cases, e.g., where mulch is being used to keep soil insulated from extreme cold, you may want a six-inch deep mulch. For this calculation, it's obviously just a matter of doubling the three-inch estimate.

Try it today! It's fast. It's easy. And it will save you time on your next ecological landscaping project!
