I've recently built two raised garden beds, each measuring 2ft by 10ft and about 16 inches deep. To keep weeds at bay, I put down a weed barrier since I couldn't find any cardboard. I planted some veggies about three weeks ago and just added more barrier underneath my watermelon, honeydew, and cantaloupe plants to help prevent weeding and keep them off the grass for the season. However, I've noticed that the barrier seems to be holding water and I'm worried it might affect drainage in the beds. The barrier isn't perfectly shaped, meaning water might drain to the edges. What issues should I be aware of? Will it hurt my raised beds' drainage capabilities?

Your weed barrier isn't exactly waterproof; it just might have sediment that clogs it over time. If you're using good permeable stuff, it should drain alright, but keep an eye on it. A lot of people swear by soaking it in a soap solution to help with drainage, especially if it's not breaking down as it should. Just give it time and moisture exposure; it'll usually work itself out. But if the plant roots are sitting in water for too long, that's not good!
It depends on what kind of weed barrier you used. A lot of folks have issues with these because weeds can still get through, and it can be a hassle to remove later. Typically, a good mulch layer does a better job and is easier to deal with. About the water drainage, if you've got heavy clay or silt soil, eventually those fine particles can clog the barrier. That could lead to a soggy center, which isn’t great for most plants—just some will handle it better than others. Honestly, if you're looking for something that works better long-term, consider using wetted cardboard or butcher paper instead next time. They’re effective and break down quicker!
I used a basic brand too, just bought it last minute. It was all I had at the time!
Your concern's valid, but as long as the barrier drains somewhat, your plants should be okay. Keep an eye on water buildup at the bottom; if you start seeing issues, you might need to replace the barrier later on. I'll say, mulch really can be your best friend here!
Don't worry too much; your raised beds should still drain. I've used weed barriers under my boxes and my plants are thriving! Sure, you might get a few weeds from blown seeds, but it’ll keep the tougher ones out, like crabgrass. Just monitor the moisture and it should be fine!
Mine beaded on top too but it's been under soil for a bit. Hopefully, it lets water through as things grow!
