Use wet-strength paper bags in place of plastic bags for curbside yard debris collection: That’s the plea of the Anne Arundel County Department of Public Works.
I wish the county would make that mandatory, as it has been for residents of Montgomery County since the yard-waste composting program started in the early 1980s. Paper bags compost, while plastic bags have to be ruptured and emptied before composting can begin. Furthermore, the emptied plastic bags — plus some of the contents — have to be dumped into landfills, thus adding to our critical landfill problems.
Rupturing and emptying plastic bags in large quantities is costly, time consuming and results in shards of plastic becoming part of the finished compost. The equipment is costly and frequently becomes clogged with shredded plastic, requiring down time. Screening the finished compost removes much of the shredded plastic, but there’s always enough remaining in the compost to lower the quality of its appearance. Since black plastic bags are not biodegradable, the residue will remain in the soil for eternity.
If you compare LeafGro made at the Dickerson composting facility in Montgomery County with the same product made at the Western Branch composting facility in Upper Marlboro, you’ll see the difference. The Montgomery County LeafGro has a uniform rich brown color and smooth texture, while that made in Prince George’s County has shredded black and sometimes white plastic scattered throughout.
There are other advantages to using wet-strength paper bags. They cost less, are made from recycled paper and cardboard, fold flat, are easy to store and are environmentally friendly.
Better yet, compost your leaves and put them to work for you as soon as they fall.
Use Leaves for Mulch and Compost
If you have a leaf blower, use it to mulch by blowing fallen leaves under the branches of your shrubs, hedges and other woody plantings.
I’ve just gotten my first leaf blower, from daughter Bonnie who thought all of this leaf raking was getting to be too much for old dad. At first, I felt insulted that she wanted to deprive me of good energy-burning exercise. However, on revving up the Stihl blower, I discovered that it was perfect for blowing leaves under my azaleas, hollies and red-top. In the past, I spent hours pushing leaves with a rake under these very same plants. With the blower, I moved twice as many leaves in minutes.
Leaves are the perfect mulch. They cost nothing and neither alter the pH of the soil nor release toxic levels of manganese, as does hardwood bark mulch. A good deep layer of leaf mulch over the soil will delay its freezing, thus making more water available to the roots. Leaves provide essential plant nutrients upon decomposition, suffocate weeds because they can be piled higher and deeper than bark or wood mulches, do not compete with the roots of ornamentals for nutrients and are dependably available every fall. Mother Nature has been mulching her gardens with leaves for eons.
I have never in my life purchased a bag of mulch. I have always depended on using the leaves that have fallen from my own trees and shrubs. I’ve also saved the county government money by collecting my neighbors’ leaves and using them. It has always bothered me to see homeowners place bags and bags of leaves at the curb each fall, then in spring bring home bales of peat moss, compost and mulch to use on their landscapes.
