Best practices for Growing only windmill palms?

[Fburg Palms]

Hello all, I have 170 windmill palms growing in my Fredericksburg basement. I’m learning by trial and error and want to learn best practices to ensure best seed purchase, soils, and germination practices. Any knowledge already known would be appreciated. FYI:  I have a 20+year old windmill pams I planted in stafford Va that survives.

Beautiful looking windmill palm. When it comes to palms, windmill seeds are about the easiest to germinate and have about a 98% (guessing) success rate. No help really required.  Some people (myself included) will sow a bunch of seeds in a community pot. They can grow together like this for a year or so until they are ready to be individually potted up. This helps in the short term to not take up as much space and hassle of moving them in and out during cold weather.  Speaking of, I generally bring mine in when temps threaten to go below freezing overnight.

They seem to do fine in most soils except soggy and those that don't drain well. Sandy soils may be their least preferential. Mine love the clay soils here as long as it drains well.
