I have used 4 mil black plastic in my vegetable garden to retain moisture, eliminate weeds, warm the soil - for my tomato, pepper & melon crops.
But that field is plowed down each fall and all traces of the plastic are removed, washed/sanitized, dried and re-rolled for winter storage. The plastic can last for up to 3 years.
For the permanent plantings in my perennial beds I used commercial poly fabric woven fabric mat used as a foundation for road construction. When I initially designed my perennial beds, I layered manure, element nutrients that my soil test revealed I needed, roto-tilled the works, laid the fabric mat, tucked the edges, pinned the seams, scored the planting spots, dug the hole, planted the perennial, broadcast 3" shreaded hardwood mulch.
That fabric mat has lasted 25 years. Of course the wood mulch has to be replenished every 4 years. If a plant dies, it is removed and the scored flaps are smoothed back in place and wood mulch applied.
When a perennial, like this hosta, outgrows its scored hole, I simply score the fabric back further and tuck it under.
I'm due for a couple of loads of wood mulch, but this gives you an idea of the end result.
