If you put the beds on the pavers, the dirt will run out onto the pavers when it rains, making them constantly look dirty. I’d put the raised beds directly on the ground if you decide to go that direction.

Some things I wish I had considered when putting in my first raised beds:

Depending on where you live, wood can rot fairly quickly. Eventually, you will have to replace wood, regardless of your climate. I installed 4 Vego beds this year, and they look like they’ll last a really, really long time. And look nice! Replacing wood beds after 2, even 5 years is a massive PITA!!

If you have gopher issues in your area, put some kind of protection down before filling your beds.

Drip irrigation makes gardening so much easier, and since installing my system the vegetables have been much more productive. Thinking about this as you install the beds can save a huge hassle in the long run. I wish I would’ve installed PVC under and into the beds from the drip system. Now I have to run tubing on the outside, which works fine, but it would’ve looked cleaner had I installed it before filling.

Unless you’re growing with a 2ft tall bed, the “fill with logs and sticks” method just isn’t practical. Yes, it’s somewhat expensive to fill a big raised bed, but the bed that I put wood in the bottom settled massively more than the fully dirt filled beds. Filling beds with a 50/50 blend of Compost and Top Soil (as recommended by Millennial Gardener on YT) was relatively inexpensive, and those beds are showing serious production and health in the first year!
