This one was just asked. I believe it was determined to be off topic in the definition phase of this project (In the spirit of This off topic question and this one too ), but I'm not sure so I'm asking here. I'm really not trying to be a stick in the mud, just trying to bring some definition to the board.
The problem I have with that specific question is that it seems more on-topic in the DIY space than the gardening (or landscaping) space. I can think of two modifications that would push the question our way:
1) Change the thrust of the question from the mechanics of laying pavers to the question of how to lay pavers in an aesthetically pleasing manner.
2) Include the question of how plants (such as grass) might be allowed to grow between the pavers.
I think "How do I do X?" is a home improvement question unless there is some specific aspect of the question related to either aesthetics or plants. And the aesthetic questions are very close to the outer limit, I suspect. I just think a group of people who are focused and expert in home improvement in general will provide better answers than the (sometimes overlapping) group of people interested in growing plants.
By the way, paving stones and rocks are very much on-topic here, in my opinion, in the context of a Chinese garden. I get the impression from this question that the asker just wants to cover a bit of ground with something solid.
I'm more interested in the site for the gardening Q&A for my vegetable gardens, but there's a lot of knowledge overlap with "hardscaping", and it would be helpful to get landscapers in this community too. So long as the questions are properly tagged (this one is), I think this is no problem at all and should be considered perfectly on-topic.
It is no wonder that all I've seen on this site is about 'gardening' but very, very little about landscaping. Aesthetics!!??? I've spent most of my life involved with nothing but aesthetics? Amazing. No way...
Landscape Architects should be the first to be on site, even to chose the site. We are taught functionality. Something that functions correctly is therefore aesthetic. We are trained in all different sciences necessary to 'landscape' a site to benefit humans as well as caring for the environment and all of life that makes that environment, the environment we need to survive. We are taught 'the forest as well as the trees'!
Gardening is not a nicety, it is necessary. We are not separate from gardens, but dependent on their health.
Aesthetics...grrrr. We can design vegetable gardens, condominium complexes, freeways, grading and drainage, irrigation, lighting, architecture and even Utopias.
We design environments that include humans, animals, insects, plants, bacteria, fungi...etc. Very complicated but essential. This includes soils, weather, hydrology, architecture, gravel, pavers!, solar energy, wind energy...gees. This isn't about individual plants, individual sites but about how to consider everything in a design so that what one designs fits into a bigger design.
I've been looking for landscape questions and now I see why I haven't been able to find much. Are there any other Landscape Architects involved with this site? Otherwise, lacking the ability to see the larger picture, this site should be called Botany, period.
Yes, pavers are a necessary part of the flooring package in some designs. Just as lawns, gravel, granulithics, boardwalks, asphalt, concrete...'steppable's' and even astro-turf are in the same category. Pavers installed correctly, can vastly increase the value of a home but more importantly can make a highly functional, easy to repair, easy to maintain and aesthetic flooring surface. There are tips we as Landscape Architects can provide, such as never have the long side of a paver perpendicular to the primary views. How not to succumb to mortar, concrete in their installation. How to use pavers instead of wood decking...impervious versus pervious percentages of materials as specified by codes.
I think this site needs a much clearer definition. A main objective/goal. Why are we all working our butts off answering these questions over and over again? For points and badges?!? Grin. I've probably said too much. But I feel better!
