I am going to build some borders and "planting boxes" out of leca blocks, 150x190, which I plan to glue with stone adhesive.
The blocks will then be plastered (the part that is above ground)...
The blocks don't have any indentations for reinforcement, so I'm wondering if it's needed at all?

Depends on the altitude
And what goes on the back, fill all the way up to the edge or, it is the pressure from behind that brings down a wall, just make sure there is drainage for any water behind. If water stays in the masses, it can freeze through the wall, become tjäle and expand, causing outward pressure, not good, otherwise no problem with not reinforcing at such a low height.
As you said, planter boxes, filled on the inside or outside? To about 5 cm from the top (normal). Having a platon on the inside means no water can penetrate the stone. It is permeable to water and in the autumn it doesn't dry out, so frost cannot form in the stone, which is good. Adding insulation on the outside is a bit excessive, not much happens at such a low height.
