Does this establishment have transport chairs for elderly?

They do have wheel chair to rent

Non-motorized is fine. Nothing fancy, just would like to show the garden to my 89 year old mother-in-law while she is visiting.

Not motorized, no

They have a few wheelchairs available first come first served. They are not motorized.

I think you have to bring your own

I do not believe they do, I have never seen any. Call to be sure.

Mm you mean wheelchairs?

I believe so
