The grape arbor

My family tells me that no outdoor kitchen is complete without a grape arbor so.....

The plan is for a raised gravel bed inside a retaining wall with planters for grapes in 3 corners and a set of steps leading out to the yard with flower beds on both sides

First we put in a drain to route the water off the carport into the pond

Next we excavated a level base for the retaining wall

The PVC risers are for drip irrigation for the grapes and other plants not shown here is a pressure supply line for misters in the arbor overhead. We're in Texas so everything is about the summer heat

I dry stacked one corner to check the elevation and since it was spot on I thought I'd leave it at that

Next I stacked the wall. I made it 3 courses before I decided I needed to play World of Tanks for a while. 

Next time I'll do the 4th course, the steps and the planter boxes

Here is one of the planter boxes going in

Next we fill it up

We were working with unsorted gravel so...

First we filled with this

Then we  screened out fines like this

Which gets you this

And this

And finally this

While this goes to the new rock garden
