We don't have bottles but we have glass water balls or plant nanny watering spikes which poke down into the soil and then you can insert a wine or soda bottle into that(Google plant nanny for a much better visual description)
I have one, but Planters Seed Co, has a variety for sale So Yes.
I really can't say if they do haven't been there since they put their plants out, but you can always call them and ask!
Yes they do
