You should be putting them in Brown, biodegradable leaf bags. You can buy them almost anywhere, discount stores have them very inexpensive (5 for $2)
Putting them in plastic bags defeats the purpose of bagging your leaves.

We are closing older Trash and Recycling issues from 2011-2015 in order to focus on current Trash and Recycling issues. Many of the older issues were addressed through our regularly scheduled collection but were never closed. If your Trash and Recycling issue remains please open a new See Click Fix issue. Thanks.
