Will A Raised Bed Liner Hinder Root Depth On My Garden Plants?

Question

Hi! I am doing raised beds for the first time this year and thought a liner would be great for keeping weeds down but then wondered if it will also cause problems with my vegetable plants getting enough root depth? Any insight on this would be helpful.

Answer 1

You really don't need a liner because the depth of the soil, plus any mulch will prevent weeds from germinating below the beds. You are more likely to get weeds at the top of the soil, but mulch will help.
