Hi, I am a newbie to the group but I need some help. I have about 70 Hoyas. I just discovered that two of them have Spider Mites. This is a problem I have never dealt with before. My Hoyas are hanging in several trees in the yard. I am afraid they will spread to other plants. Any help is greatly appreciated!

Hi Tanya and welcome to NGA!

Spidermites flourish in dry environments .. they don't like humidity. I'd take a hose and spray the infected hoyas really well followed by a few spritzes of a good insecticide. Then increase the humidity around the plants by misting the plants daily if the air is dry. If you are adverse to using chemicals then you can hose them down and wipe off the leaves with a damp paper towel - top and bottom and as said above, increase the humidity.

Thank you, this is the dry season down here so I will water them more often. Thank goodness the rainy season will begin in about a month.

You're welcome!
