I've come across some mixed opinions regarding the use of tarps underneath garden beds. Some people claim that placing a tarp can help prevent pests, which has been a significant issue for me lately. However, others warn that it may hinder drainage. What are your thoughts on this? Is it really beneficial to have a tarp, or am I better off without one?

From what I've learned, keeping the soil in your garden bed connected to the native soil below can actually help plants thrive by accessing more nutrients and water. So overall, it’s a no to the tarp!
Using a tarp isn't really a good idea because it can block drainage and disrupt the natural flow of water. It might keep some pests away temporarily, but it actually can lead to more issues in the long run. Instead, focus on creating a diverse garden environment to handle pests better.
I would definitely avoid using a tarp under your garden bed. Tarps often have chemicals that can leach into the soil as they degrade, and they can create a mini 'pool' effect that prevents drainage. Instead, consider identifying the specific pests you're facing and tackle them naturally, like introducing beneficial insects to your garden.
