This is my Hoya kerrii. For last few weeks, I have been seing these black marks on the leaves,specially ones that face the lawn. Plant is on the east side of patio, gets may be a couple of hours of morning sun.Sprinklers are off and I water without wetting leaves.What should I do and what is it?

If they were mine I'd say they were too close to a cold window... doesn't help you in Florida though, does it?

Day time temp 80 plus minus 2 degree and night temp 70 plus minus 2 degree mostly. Did rain a few times but plant is not located in direct rain. However, there has been couple of 'cold' drafty days when night temps went down to mid 60s. location is protected but has good air circulation. Other plants nearby are fine.
I water only when soil is dry to touch. Soil keeps drying too quick here though.

Plants grown outside often get insect damage and are more susceptable to temperature flutuations........ My kerrii dropped a few leaves recently.poss the cooler eves, but its fine otherwise and has been outside a few years now

It's all about choices.
Looks like bug bites to me. BTW, H. kerrii likes to be quite dry...she is really succulent.

You might just spray with an all purpose fungicide to be sure....

Thanks a lot. I do not water it much and soil is kept on the dry side . I will try spraying and may be protect it better . Temps predicted to dip to 60s tonight. I will just cover them all.

My temps in winter drop to 55º during the night sometimes on a cold night as I'm quite high up on the island ( up away from the tourists where 15 mins down the road its a good 10ºF warmer at night.) and I havent lost one to cold yet....then it warms up again quickly during the day to mid 70s this time of year....just for a couple of months, but we struggle thru it somehow

And here in Florida, they are talking about brief 'cold wave'. Hilarious!

yeah I spent yesterday afternoon dragging all but the biggest Hoya's into the greenhouse or house as we have a few nights coming dipping into the mid - upper 30's. and then a few more in the 40's. That's when I pull them in. Makes traversing around the greenhouse interesting...Hardhat area...as I keep banging my head on pots or running into dangling vines of pots hanging from the rafters. And we were wearing Shorts Christmas Day...

I have spent a lot of money on concrete pumping to build a patio in my Florida residence, which on the top of a small hill. I wanted to plant some wonderful plants in its surroundings. Now I am afraid after reading your post, what to do?
