Hi Rick ....
No they didn't say what they thought might be the best mulch material, but mulching with gravel is out. My older body is not up to hauling enough gravel up to the house pad level to mulch the whole area ....
Actually, our neighborhood is probably one of the most fire safe areas in town since CalFire did the fuel reduction work. All of the trees were properly limbed and all of the scrub brush removed. Even the blackberries were taken down and all of the dead growth under them removed. They also built a fire break between the meadow and the blackberry cliff.
We didn't remove the blackberries because of possible erosion problems. Jett, the owner of that property, continues to have someone cut them back every year. He also owns the property above me and has removed all of the junk pines which were more of a fire danger and has left only the oak trees.
I am really pleased that my neighbors were willing to join together to have all of our properties worked on for the fuel reduction project. My property had the least amount of work done, but with all of us getting it done at the same time and continuing the work to keep things fire safe, that is one thing we don't have to worry about.
Smiles,
Lyn
