ᐅ Using granite palisades for raised garden beds with a dimpled membrane?

Hello, as a tribute to our late son, we want to plant a tree for him in the garden. It is a flowering cherry tree.

The tree is intended to be the visual centerpiece of the garden.

Therefore, I have built a raised bed from granite palisades.

These are 75cm (30 inches) high and will ultimately protrude 50cm (20 inches) above ground level. Nearby there will be a wildflower meadow; here the palisades are 50cm (20 inches) high and will stick out 30cm (12 inches) from the ground.

I applied 10-15cm (4-6 inches) of frost protection material underneath, compacted it, and then poured the concrete. The palisades are each set in concrete to about 25cm (10 inches) and 20cm (8 inches) respectively.

Now everything should slowly be refilled with soil.

Does the dimpled membrane (often recommended) have any purpose other than preventing soil from falling through small gaps? Granite is a stone that generally does not absorb moisture.

In this case, I would place the dimples facing inward so that the membrane lies flat against the stones.

Nice idea. I wouldn’t install a dimpled membrane. I didn’t use one for my sandstone wall either.

That’s a nice idea, but I’m afraid the tree isn’t very suitable for that. We had an ornamental cherry tree in the front yard when we bought the house, and the tree cracked all the paths and edging around the beds. Nothing grew under or near the cherry tree anymore.

However, the Japanese flowering cherry is a deep-rooted species. So it probably shouldn’t cause any damage…

To be honest: given the circumstances, I would avoid creating a recessed area and instead place the tree directly in the garden, allowing the ground to merge naturally.

I respect that.

My wife and I were also fortunate to have a total of three daughters.

Each child receives a tree, but for our son, it should be something special since he is no longer with us. That’s why we came up with the idea of using granite curbstones back then. They also match our base render very well.

They are already installed.

In front of them, there will be a wildflower meadow or something similar so that many bees and other insects can roam there.
