Mitch, those on the bottom 3 photos looks like mealies but the top photos I don't know what it is. Try straight alcohol spray but not in the sun, it'll burn the plant. Give drink of the Bayer's trees and shrubs systemic as soon as possible and isolate the plants so the other plants doesn't get the mealies and what ever that other spots are.

hello. I am new to posting on forums, but read a lot about your hoyas. I am interested in what the experts think could be the spots on the hoya leaf. The ones that look like they are eating the skin.

I am wondering what the other white spots are too. Thank you for the help with this and other answers. Those hoyas are nice but the stuff on them isn't. Sorry for that.

Mitch, contact the vendor you purchased those hoyas from.
She is extremely helpful and will know what they are, since
they came from her.

well thanks everyone for the input! I talked to the vendor and she said that the white spots were most likely just dried sap and i took a closer look and i agreee (I still scraped them off just in case). However she wasn't sure about the spots on the Naumanii. I think I will just keep an eye on them and if they start to spread cut the leaves off that have them. Hopefully its nothing too serious!

Nice plants!

I think that the all look fine and the little bit of damage you see will soon be replaced by new growth. Cuttings are bound to get a little beat up looking. The damage in the first photo looks fungal in nature but the leaf looks healed so it may be fine. Cinnamon is a good household fungicide that is safe an does a great job stopping wet fungal rot. The dots in the second photo look like dried deposits from a fertilizer solution but it is hard to tell in the photo. The white spots on the stem could be areas that were damaged during packing or shipping. Hoyas have a protective sap that is often milky white and it helps to seal cuts or breaks in the vine or leaves. If it is fuzzy and wipes off it is a mealy bug but I don't think it is, let's hope not.

Nice haul you got there! Don't you love H. coriacea? Your's is about the size of mine (I got it from a DL order last year), and I see that your's is about to bloom - so that makes me think mine may bloom soon too!! Please post pics of the blooms for us to admire :)

I ordered H. naumanii from this DL order, and I am so excited to get it! Wait till you see the flowers!! And I'm assuming you meant to say that the first pic is H. erythrostemma? That one has gorgeous flowers too. Good selection indeed!

Ya i am sorry i did mean "erythrostemma"
I am extremely excited about the coriacea. Can't wait for it to open and i will definitely post pics when it does.

Thanks everyone for your advice

Mitch,
if you ever get white spots on your plants and you suspect insects, there's a surefire way to tell if its a bug...just try to smush it.

Mealybugs are fat little soft bodied insects under that outer fluff of white cottony stuff and they smush into jelly. Easy to know if you have a bug, or just a white spot caused by sap leakage
