Let's make it easy: do very little.
@cwhitt gave you good advice. Most Tillandsia can be attached to driftwood with string, glue, nails or screws (through the woody part. You can also use string or wire to make a hanging support. They will grow much better outside.
If they are growing outside keep them in light shade with no direct sun and water them frequently. I see that you are in Ohio. In the fall they will have to be brought inside if it it expected to be in the 50's.
Once inside they will need a bright sunny spot. Keep them misted. I have a friend who lives in a Manhattan apartment with a hundred plants.
YouTube can give you some ideas but I would recommend good website.
Search Facebook for Planet Tillandsia and also for Bromeliad Society of Central Florida. If you join these you will have access to authoritative advice.
Good luck.
