How advisable is using garbage bags under mulch?
Can black garbage bags be used under mulch of wood chips to keep out the weeds?

Hello P~ I'm guessing here...that means fair warning to get a 2nd opinion.
I'm thinking it might work, but over time, the plastic may become brittle and torn.
The plastic used for gardening is a much heavier weight and may be designed to literally weather better.
Check with a local garden supply and see what they recommend. Best of luck!
Garbage bags will never break down. Which is good for weeds but bad for the environment. I like to use weed fabric with metal stakes. It's easy to remove to add new plants and easy to use.
If you’re looking for an inexpensive, environmentally friendly option for a weed barrier try paper garbage bags or craft paper. Even cardboard boxes flattened make a great weed barrier. Each of these will break down over time so it’s earth friendly bit they are also very effective!
They make black plastic on a roll that is cheap. It is thicker than garbage bags, and will keep out your weeds. 3 mill thick is usually good, and the rolls come in a variety of sizes. One word of caution. Termites and carpenter ants LOVE mulch. I would not have it within 8 ft of my house, or you are going to have them destroy your property. This includes areas with wood decks.
