Here in the desert finding enough mulch is a constant problem. I spread the horse droppings and now the goat and chicken droppings in areas I want to grow. When I can get old hay I also use that or my bamboo leaves after harvesting the poles, make good mulch.
A couple of weeks ago friends were at a recycling place and they met a tree trimmer . They spoke up and asked what they did with their wood chips and leaves and got a phone number. I called hoping I could get them to dump some on my property. They said they dumped on property about two miles from me and I could get as much as I wanted. I was given an address and went out there. Like a huge gold mine there was about five acres of piles of chips and mulch. What a resource. I have been making at least one trip a day to
bring a truck load of mulch home This is going down over weeds to stiffle their growth and preserve the nutrients in the soil.
Mulch is like water. It grabs rain water and holds it. The ususal desert down pours will be absorbed rather than run off. I will get pictures soon but I must say I am very happy.
My way of handling the mulch is to put a small tarp in the back of the pickup . I carry a rake and a childs quilt/bedspread. I rake the mulch onto the bedspread and lift it onto the truck bed covered by the tarp. When I get home I simply open the back after parking where I want the mulch and pull the tarp. The mulch drops in piles on the ground and I rake it out.
If you need mulch check with local landscapers who have chippers.
