Corner for retaining wall

Morning all,

Started on backyard landscaping now that we've finished a 2nd storey. I've got a curved retaining wall (more of an elevated garden bed), about 10 m long which weaves in and out.

Made from Adbri Hudson blocks, which are rough finished on the front with two angled smooth finished sides to allow for the curve. If possible I'd like to re-use these for a straight garden bed in the same area, but this means I have a requirement for 2 x 90 deg corners. They are also alternate stacked (like brickwork). I thought of 45 mitre, but is complex due to the alternate stacking and finish of the blocks.

Any other ideas for the corner, or am I better changing to different blocks which have corner units?

Cheers,

Tom

Square Corners

To build an outside corner begin by placing a half unit on the corner then lay the rest of the base course working from the corner block out. Begin the second course with another half unit, this time aligned with the alternate wall. Place the second and third blocks on either side of the corner unit and fix with concrete adhesive. Continue to alternate the corner unit orientation with each subsequent course.
To build an inside corner, place a full block at the corner then lay a second block at right angles to the first. Continue laying out the rest of the base course working from the corner out. On the second course lay the blocks on bond (e.g. like bricks) on one side of the corner. Once the second course of one wall is established, begin the second course of the adjacent wall. Partial units may be required on this wall to maintain running bond for better strength and appearance. Block placement in the corner should alternate direction with each subsequent course.
