Overwintering Mandevilla in coastal Georgia

20 years ago

DH, DD, and I went to a plant sale on Saint Simons Island today. There were 2 plants that DD (age 5) just HAD to have. One is Red Riding Hood Mandevilla. What is the possibility it will overwinter here if planted outside (we live in Brunswick)? I don't have a good place for it in the house so I'm not sure what to do. The darn thing only cost $1.95 so it won't be a tragedy if it dies but DD will be horribly dissapointed.

The other plant DD wanted had no tag on it. The woman at the nursery wasn't sure how to spell it but the name of the plant was prounounced "ex-hora". It has aprox 1.5 inch light green leaves with a red/pink fringy flower. The end of each fringe (it has about 6-8 fringes I think) is ball shaped. Sound familiar at all? I'd post a pic but the digital camera needs batteries. I'll try to get some tomorrow.

My other finds at the plant sale today were Monrovia Tropicannas for $2.95 each and Burgundy Lorapetalum (3 gal) for $4.00. I was pleased and may sneak back tomorrow to do more poking around.

Thanks!

Might your mystery plant be an Ixora? Sounds close...

Good bargain finds, Marshgirl. Oh, and a trip to Saint Simons...one of my favorite places to kick back and island-hop.

Yes, Yes Jerribell, it is Ixora. Thanks so much! I am such a dolt, what I described as balls on the end of the flower fringes are actually flower buds. They just started opening today. DOH! I guess I demonstrated just how much of a newbie gardener I am with that post. LOL!

Thanks for the help with the name!

Moving houseplants outdoors and planting?
Q

Josh, you're not the only member here who has planted house plants in the ground. :) Karate. Planting in the ground has its pros and cons, unfortunately, more cons than pros. Pros...plants will grow like weeds. Con. Depending on the plant, it might grow too big. For example. One spring I planted two, 1' Musas/Banana Trees in the ground. By autumn, they stood over 15' tall, 7-9' wide. Because of their sizes, I had to leave them out to die. I also planted a 7" Brugmansia. By autumn, it stood 3-4' tall. I dug up the Brug..many roots broke, but not enough to kill it. The following spring, I planted the Brug in ground again. It grew another 2-3', and bloomed profusely. From then on, it was kept in a large container. I also planted a few palms and a hardy Citrus. The palms didn't put on much growth, but foliage was full, compact and very green. Some of your plants would do okay in ground, but don't forget the cons.. Cons: Broken roots, bugs, disease. If you decide to plant in the garden, when you dig up, hose entire plant, including roots. Some of your plants that could be planted in the garden: Jerusalem Cherry Ardisia Elephant Ear Canna Opuntias Most of your other plants would do fine outdoors, in pots. Be very careful with the Pothos and Philo. Leaves could burn. Keep us posted..Toni

Growing Artichokes / Cardons Zone 8a?
Q
Comments (2)
glib, Thank you for the response. I also found a previous posting regarding cardoons by you with great info. I think I got caught up in my artichoke research and with both plants being in the same family, forgot to treat the cardoons as cardoons. The time line and blanching tip helps a ton. Seems I am a little late, but I think I may still try along with the artichokes and hope for the best.

dusty miller over-wintering
Q

I have dusty miller that has made it through 3 winters in Georgia! 2 being in Atlanta on a second floor balcony. This past summer I cut 6 or so inches off from the main stem. Dipped them in rooting hormone and kept them in damp sandy soil. They rooted to my surprize. My old ones are putting off new shoots at the bottom. I love having something that makes it through the winter and muggy summer. I have also found that lambs ear and white yarrow do the same.

Mandevilla has not bloomed
Q
Comments (4)
I'm in 7a and winter my mandevillas over inside. I cut them back pretty far when I put them out in the spring and keep them in full sun. I give them Superthrive and B1 at the beginning of the growing season and feed them once every couple weeks with either an all purpose or bloom booster fertilizer (I try to alternate). I also give them epsom salts and kelp extract once a month. Now that it's so hot I've been watering them daily. They are loaded with buds. Karyn

No No NO, you are not a dolt! I am the newbie gardener here. I've been in GA 3 1/2 years, and this year I finally decided to try and grow something, lololol. Anyhow, glad we got that one figgered out, girlfriend.

Sorry I cannot help you with the mandevilla question though - I've never grown one. But I'm betting PB or Wilmingtonislander will see your post and respond soon...

I have over wintered my Mandevilla, in the green house, but most of the posts I have read about then, say just enjoy then for the season and then pitch them, as they are rather inexpesive, and not worth the trouble and space of keeping then inside. They will not winter over, in my garden here in Lillian Alabama.

Yes, almost impossible as I believe they are indeed a true zone 10 plant...just can't handle any cold.

Thanks for the reponses WannaB and WI. Your responses confirmed my fears. I think I'll leave it in a container and find somewhere for it to live in the house for the winter as an experiment. I probably won't do that next year but DD really loves the silly thing so it's worth trying to nurse it through this winter.

Thanks again!

marshgirl,
Mandevilla are easy to overwinter. There are two methods. Both work. In both cases place plant in a good sized pot with good draining soil. Then....
1. Cut the vine back to within 12' inches of the soil line. Place pot in a bright, sunny window and be patient. Or....
2. Before potting cut back the vine so that it is about 4' to 6' long. Now work along the length of the vine cutting off every side branch to within 4" of the stem. This is called 'saddle pruning'. Now, pot the vine and jam some sort of support for the vine in the pot. I loop a long, fresh cut piece of bamboo in an arch form which works well.
Again place in a sunny window.
Don't be surprised if your vine is grumpy over the winter and looks dead. As spring approaches it will spring to life. When you return it to the outdoors remember to give it a hardening off period to adjust.

thank you Nandina- I really want to keep my mandevillas. I paid $15 each for them at Home Depot- I need to find the $1.95 plants if I can't overwinter them

The landscape person I purchased my mandevillas from told me to prepare from winter by potting it in a big pot (3x the size of plant) and cut it way back and bring it inside ...... OR to keep outside, pot in same big pot, and dig a hole in the ground for pot and plant, cut back the plant and finally mulch alot around it so that it is protected from the winter freezes and that is here in southern Louisiana!
I've potted them , now I'll wait another 2-3 weeks before bringing them in. Hope it works because I really don't want to loose them. Don't think fertilizer is used during the winter months. Does anyone know?
