How to overwinter my Lantana indoors.....I cut it back and it started to green up and shoot up stems but now its leaves are curling and It looks like it is dying ? What do you recommend I do ...Cut back again and put it in the coolest and darkest place and just barely water ?
I want to keep this alive because I don't want to try to find this color again and I had to pay quite a bit for it and didn't want have to pay for it again .
What do you think 🤔 would be the best way to keep until I can put it back outside again?????

I would go the opposite way and give it as much light as you possibly can, including grow lights. If the stems get a bit stretchy just trim them back.

I'm in the cool, dark basement camp. It will probably dry slowly, just don't let it get literally all the way dry. Lantanas are seasonal here, going completely dormant and re-growing from the roots in the spring. Putting it in the basement shouldn't kill any of the branches, just cause them to defoliate. Getting frozen is what kills the branches here.

I think the problem started when you cut them back...
They always say that cutting stuff back is going to produce vigorous growth.

At my house, lantana goes dormant in the winter and stays dormant until Spring...

Winter is when I work on getting new plants.

While lantana grows from cuttings, easier is to propagate by layering.

Your plants have been depleted by the treatment they've received...
I'd be afraid to put them in the basement at this point... What I would suggest... is to get them in a lower temp... + get them more light. I'd want to keep the growth alive + toughen it up... + stop watering so much.

next year... you could try rooting the cuttings, and attempt keeping grown plants in garage or basement...

Oh yeah... stop cutting!

This is my first year to try to winter over lantana. I brought in two in the fall before our first frost and have been growing them as houseplants more or less. They both dropped all their leaves and looked dead for awhile after I brought them in. Now they've leafed out again and look alive but not great. I have them in my walkout basement near a south window. It's a little cooler in my basement than the rest of the house. There's a balcony above the south window that shades it so they're not getting as much light as you would think. I'm letting the soil get pretty dry between waterings. It's still just January so it's too soon to say if that's a good method.
I never have good luck wintering stuff over in my garage. It's on the north side of my house and gets below freezing. Also has a big west window so it gets too hot at times.
