Building a dry stone wall with limestone - tips?

Hello everyone, I want to build an 80cm high dry stone wall made of limestone; the stones are "rugged," meaning completely untreated, so I first have to work on them a bit with a hammer. I have already prepared a concrete foundation at the bottom. As a base, I built a concreted shuttering block wall, which holds back the load from the mountain, statically calculated. In front of this, I now want to lay the limestone stones. The stones are about 5x20x5 cm in size, very different.

I now have the following questions for the natural stone wall experts:

1) Although I already have a foundation, do I still have to set the lowest stones again in concrete, do I simply lay the stones on the foundation, or do I fix the first stones with trass cement mortar?

2) Is the supplied trass cement mortar suitable for limestone regarding discoloration?

3) I want to build a dry stone wall because I like joints without pointing. Can I compensate for unevenness in the stone placement with trass cement mortar in areas where it is not visible? For example, where the stone is not completely straight.

4) Do I fix the natural stones at the back to the shuttering block wall with mortar and press them on?

Is there anything else I should consider?

I really thank you in advance for your help.

No one can help me?

Sorry but why don't you just try it, then you'll know if it works... Or are the stones counted?

I just want to know how to do it right before I start

A dry stone wall is - as the name suggests - built dry, meaning: without mortar. This is not only what makes a dry stone wall appealing, but also provides space in the joints for wallflowers and insects to find shelter.

If you feed the rooster with "Bauanleitung Trockenmauer," you actually get very nice and helpful results.

A concrete foundation is not necessary. If I understood you correctly, the dry stone wall is built directly on the slope. Then you just need to make sure to maintain a 10 - 15% incline. This way, the wall won't tip forward.

If I understood correctly, he does not want to build a dry stone wall but rather a concrete block wall "clad" with a facing natural stone wall. In my opinion, this makes the construction of a proper dry stone wall without mortar, etc., impossible, because a dry stone wall usually only gains stability through some long stones extending into the slope or the backfill. Simply placing a few stones dry in front of the wall will certainly not work here unless the wall is accordingly strong/wide.
