Making your own compost at home provides two great benefits. It’s a great way to recycle your yard clippings and kitchen scraps, and the end result of the process provides free mulch for your plants. Our Arizona summer is just around the corner, and placing compost or other organic mulches on the surface of plant roots is one great way to get your landscape through this long, hot, dry season.
A two- to four-inch layer of organic mulch will help keep roots cooler, retain soil moisture, reduce weed growth, improve soil structure, and increase nutrient holding abilities of the soil. Compost or other organic mulches can reduce plant water needs by as much as 30%, and best of all, if you are composting, you are diverting waste from the landfill that would produce methane, a potent greenhouse gas.
When installing new plants, place compost or mulch on the surface of the root zone after planting and then top with rock or granite. Because mulch breaks down very quickly here due to the heat, it is a good idea to replenish organic mulches around existing plants once or twice each year.
Here are our favorite tips to share for successful composting in the desert:
- Check with your City/Town and see if they offer recycled trash barrels as composting containers.
- Place your composter near a water source so you can occasionally wet it down to speed up decomposition.
- Add some helpful ingredients to your compost pile like coffee grounds (check with your local coffee-house) or horse manure (check with local stables).
- Keep mulches about three to four inches from the trunk or stem, since too much moisture against the bark can cause damage.
