I am in tampa fl and cooler fall weather is here (yay!). What temps are too low to have orchids outside at? I have some phal, catt, den, and vandas. Also if it is fine in the day and too low night do I cover/bring in or only when the 24 hour temps are too low? Its my first winter with orchids so advice is appreciated.
PS is it even possible to cover orchids like ground plants or is bringing inside the only way?
