Be Prepared to Protect Tender Landscape Plants from Chilly Nights in South Florida. Doug Caldwell

Above: Crossandra are very tender and will brown out when temperatures dip below 45 degrees or so. Below: Ixoras are sensitive as well and will defoliate all their leaves, it seems almost simultaneously, about 2 days after a cold snap.

COLLIER COUNTY EXTENSION OFFICE OFFERS TIPS TO PROTECT PLANTS IN COLD WEATHER
Collier County is known for its beautiful beaches and abundant sunshine, but even paradise gets a little chilly sometimes. As residents dig out their jackets and fire up the heaters, our luscious tropical plants don’t have the luxury of donning warm winter-wear. They count on us to ensure they can endure those frosty mornings.
While you may prefer your wool sweater to keep you warm, Doug Caldwell, Ph.D., Commercial Landscape Horticulture Extension Educator, says plants prefer frost cloth. “Frost cloth is one of the best ways to insulate plants, especially tender flowering annuals because it isn’t necessary to prop it up, off the foliage,” said Caldwell. If you don’t happen to keep frost cloth handy and can spare the bedding, sheets can protect plants as well. However, with heavier material, support props are needed to separate the material so that it doesn’t touch the plant to best protect the foliage.
For those that can’t spare the bedding, or if you are looking for a more natural approach, pine straw can be spread across the tops of sensitive plants to shield them from the icy embrace of Jack Frost. Pine straw or even old pool cover pieces can also be used to mitigate damage to tropical shrubs or young fruit trees by covering the base of the plants.
Even after a night of cold temperatures there are things you can do, or not do to help the flora flourish through future frosts. “After the freeze, avoid pruning, as new growth may be stimulated which will be more vulnerable to subsequent freeze injury,” Caldwell said. “In fact, it is best not to prune between November and February to avoid inducing tender new growth that will be prone to freeze injury,” added Caldwell.

Great comment! I have read that sago palm is susceptible to ganoderma sadly...

When folks who have lost a palm to ganoderma here, they usually want something that looks like a palm. Here in Indian River County, I suggest 3 plants which sort-of resemble palms: Sago Palm, which is a cycad but really resembles a plam Ponytail palm, which is not a plam nor a cycad and Pandanus, or "Screw Pine", which is neither a palm nor a pine but a very interesting tropical plant with a very large, interesting round cone-type seed pod when mature and spiraling leaf arrangement.

That's a tricky one as slippers/bulldozers are not as targeted by commercial divers and I don't believe many slippers get caught in regular spiny lobster traps. I would reach out to some local seafood houses to see if they get them in occasionally, request them from a distributor or if they get some of their product by divers, ask if you could make a request or be contacted when they come in. I know a few Tampa area commercial divers and I believe they sell their speared fish to Shelly's Seafood and would check with them https://www.shellysseafood.com/. Good luck!

Hi Earl, I would be happy to take a look at a picture, my email address is sipos624@ufl.edu. Cane toads and other invasive species are usually/can be more common in urban and disturbed areas where the native critters are pushed out leaving an open ecological niche. I did a search of the Everglades Conservation Area 2 A and looks like it backs up to some urban areas on the East side. The FWC promotes reporting sightings of invasive species as the best form of management is early detection and rapid response before the species become established. You could report the sighting on the I've Got One app or on this website (url below), you can also see where some invasive critters have been spotted/reported as well https://www.eddmaps.org/distribution/ . For cane toads they may not mobilize a response as they have been established but researchers could find the information useful and interesting if they are moving more towards rural undisturbed areas. -Mike

I got this last night in Everglades Conservation Area 2A. miles from anything dry. It looks like a cane toad and is the size of a bullfrog. secretions from the glands behind the head. if it is a cane toad, and they are reproducing, bad news for natvive glades frogs. i cant figure out how to attach photos but glad to email to you.

Our HOA is requiring residents to hire a tree trimming company to remove the royal palm seed pods ($55 per tree). Do you have any written materials to support nature's "self pruning" of royal palms? The royal palms on our property have never been pruned but the new HOA is determined to excessively prune these palms. Any help would be appreciated. Thank you for your time.

I just watched NBC2 news with Twyla Leigh and the Vanilla Bean vine plant. My friend, Dr. Henry Herman, Professor at FSW in Fort Myers, gave me a cutting of his plant and it was amazing how healthy it was and grew to flower. I had moved from that home, but would love to have samples to grow at my home in South Fort Myers. I am a master gardener and would love to help produce more Vanilla Bean Orchid plants. Please contact Twyla Leigh at twlaleigh@ufl.edu

Hi Albrey, The pictures are great! I believe there is a huge value of having real fish pictures for identification. I'm beginning to stockpile photos of distinguishing characteristics for all the species I now catch/do a segment on. I'm trying to do a species profile/fillet video a week on edible fish found in Florida on our Collier County Sea Grant Facebook page https://www.facebook.com/CollierSeaGrant

Thank you for your kind words! If there are any invasive species you're interested in particular, I would be happy to answer your questions or put you in contact with an expert within the University of Florida network. Feel free to reach out with any requests or ideas for future programming. Have a good one!

Thanks for your info--i didn't realize this was the problem with my porterweed until the plants were quite infected with the caterpillars. I've cut the stems as you suggest...but continually find many I've missed. The infestation is pretty established. What's the best course of action? I've cut back the porterweed substantially, but probably the moths are around and will continue to infect. If I remove the porterweed completely...and start over, must I continually (almost daily) check the plants for infestation? I've had the plants for a few years before the problem occurred.

i have a big infestation of this on my native porter weed. Didn't really notice it until it has really devasted my plants an is spreading. It is overwhelming the plants. The caterpiller appears to burrow down inside the stem and then the branch dies. It may be too late for me to control it by just cutting the infected stems out. How do I get these insects under control. Do I need to remove all the porter weed and let the ground remain dormant for a while? I have the infestation in my backyard, but have porterweed in the front also, and I observed early signs of infestation in the front. Would appreciate your advice. So glad you've identified my problem.

Thank you so much! Wish so many of my "natives" and Florida friendly, like Wild Coffee, were a bit more cold sensitive. Not sure how I'll have time and ability to protect my 100' hedge row, but we'll give it a valiant try.

For the royal poinciana caterpillar, carbaryl or a pyrethroid (bifenthrin) should work. Remember just to spray the bole of the tree from the ground up to 3 or 4 feet. No need to spray the canopy as explained in the posted FSHS article.
