I know very little about hoyas, but have about 4 of them that were given to me last year. They are growing well on my porch and are somewhat sheltered by the weather. Currently, the weather is in the 60s-70s, but drops into the 40s-50s for a short period at night. At what point do I need to bring them in. I certainly dont want them to freeze. Thanks for your help.
when to bring them in
If any of your hoyas are in the H. carnosa or H. pubicalyx groups, they should be able to tolerate those colder temps at night. Some others are more tender. Hope this helps.
