I just picked up my first 2 Mandevilla Patio plants. They are both in a 3 qt containers. One has red flowers and the other has pink flowers. I need a little advice please. Do I leave them in this pot or do I transplant them to a bigger one? Do they like full sun or partial sun? I also got a 2.5 qt Hibiscus. I assume this is also tropical and will need to come in before it gets cold. Should I transplant it to a bigger pot or will it be okay in the one it is in? What about their water needs?
Thanks in advance for any suggestions you can give me.

I just Googled both the Mandevilla and the Hibiscus to see that their growing conditions are so I will go by what I read. That is what I was thinking so they just reassured me. Thanks anyway.

Hi Jeanne,

Mandevilla are lovely tropical plants. I currently have a red one in a hanging basket that's outgrown it's pot and really needs a larger container with a trellis to climb and vine around.

Is your Hibiscus the Hardy Hibiscus (Hibiscus moscheutos) or the Tropical Hibiscus (Hibiscus rosa-sinensis) that are grown as annuals in colder zones?

Rita Randolph (she edits Fine Gardening Container mag) suggests hanging mandevillas, she says they perform better draping down than climbing up. She has a couple of pictures on her website. http://ritasrareplants.com/gallery/

Whether you trellis them or hang them, use the largest container you can handle. They grow lots of roots, fast. The 'Alice Dupont' is a large , fast growing pink one, The others can do well in baskets, but will need lots of water as they become root bound. I have had one in a hanging pot for at least 9 years, but I do have to root prune it every couple of years.

Thanks Lin, Alice and Carol, I have a couple areas where I can hang my Mandevilla in the house. One is by the deck doors on the east side of the house where it would only get morning light. Should I hang it in a west window where it would get afternoon sun? Our garage is on the south side of our house so I have no south windows.

@plantladylin I got my plants at Lowes and they aren't mark very well. The Hibiscus does not really say if it is tropical or hardy but the lady said that it was tropical and would not handle our cold winters. So I am planning on bringing them inside before the temps drop below 60.

Jeanne, I can't help you with the Hibiscus, as I gave them up years ago because of giant white fly. The mandevilla goes semi dormant here, even though we rarely get so much as light frost, so in either direction you can't expect much in winter. They do prefer full sun outdoors though. Mine hangs from a covered porch facing north, so gets some morning and some afternoon/ evening sun and like all of my plants is pretty one sided.

I have a red mandevilla in a 20 inch pot with a 6 foot obelisk. It has climbed that obelisk up and down and full of blooms. I suppose I really should cut it back when I take it to the g'house this fall. It will pain me to do it, but.................

Hilarious! When I first got mine it climbed it's wire hangers, traveled to it's neighbors wires, and wrapped around the awning supports. I had a heck of a time untangling it, but after trimming, it just drapes now.

I love tropicals, and in my zone 4b garden, I treat mandevilla as an annual. I usually grow it in the ground, training it up a 6-pole bamboo teepee that is 5' high. This years' plant was not fleshing out nicely, so I direct seeded Cypress vine at the base of the teepee. What a comical pair. Cypress took off in the summer heat with loads of tiny red blooms and now [end of September] all I see of the mandevilla is its blooms jutting out of the cypress vine.

I guess I need to look and see just how much I can hack my monster back.......it's going in the g'house in the next couple days. It will pain me grievously to do that, but the less hotels I have for the whiteflies, the better it is. Rolling on the floor laughing
