A Reddit user sought advice on how to kill grass on a steep hill to prepare for a native plant lawn, asking if weed fabric or black plastic would work. While these options may seem convenient, many users cautioned against using plastic due to its environmental impact, including the release of microplastics into the soil and water.
Several commenters recommended using cardboard instead. One user shared their success with cardboard, stating, “It’s the only method that worked for me.” Others suggested securing cardboard with sticks or using fallen branches as a cost-effective alternative.
Experts, including the University of Illinois Extension, also advise against landscape fabric, noting it only suppresses weeds temporarily before degrading. Instead, they recommend cardboard, newspaper, and wood mulch as better, long-lasting options.
Converting to a native plant lawn has numerous benefits, including reducing carbon emissions, supporting pollinators, and helping combat climate change by storing carbon.
