Draing for retaining wall
I am building a small brick wall for flowers in front of my house. my questions is how do add a drainage system if it's in the corner and a curve? my yard slopes down to the corner. All the drainage systems I found online only show for a straight retaining wall, i think i would need drain pipes for the vertical and horizontal walls leading to the corner, and if so how to make this drain pipe?
I have attached pictures.
Thanks.

With loose-stack blocks you shouldn't have any drainage issues as the water will leak through the vertical seams between the blocks. Don't try to make the seams too tight and use a landscape fabric immediately behind the blocks. A few inches of gravel between the landscape fabric and the soil wouldn't hurt.

You can put a layer of landscape fabric and/or clean gravel behind the wall if you really want but I don't think it's needed except to help prevent dirt & mud from washing through. Your wall is quite small and very porous so water pressure on the back side will not be a problem.

I am finally getting to finishing my wall, but i have a question. I have decided to use gravel and put it up against the blocks then add some filter fabric then fill dirt. My question is how to you keep the filter fabric up straight when filling the gravel and dirt? it seams if you start to poor in the gravel it would just pile up and slope towards the dirt.
Sorry for the dumb question but i have never done this before.

I put in the landscape fabric. Then a layer of gravel on one side a few inches thick then put several inches of dirt on the other. Alternating back and forth so the stone & dirt balance each other out and keeps the fabric mostly in the center.
