I posted a few pics & videos of bee habitat made with bricks. My house is old brick and they certainly use all the mortar and brick holes all over the building. There is a commercial version of bee bricks made with waste clay from a porcelain industry in the UK. There is another where the speaker makes them with cob. That all got me to thinking about other materials. Then I wondered about hypertufa. Lightweight would be a plus. I've never worked with hypertufa so I am hoping folks here who might have worked with it think it's a suitable material. Additionally, will it stand up to drilling? If not, maybe I could wrap rods in saran wrap and leave them in until dry and then remove. Any thoughts?
Always looking for interesting plants for pollinators and food! Bonus points for highly, and pleasantly scented plants.

I can't answer your question because I don't know.
If someone doesn't come along with answers, take a look around at some of the other threads as I seem to remember there was a discussion about hypertufa
This is an old question but let me tell you my experience with hypertufa. It can be drilled with a concrete bit. Sometimes it's easier to use pieces of wooden dowel or wine cork where you want the holes. Use the correct size of regular drill bit to drill out the wood.
