I live in Zone 6 in the Poconos of Pennsylvania which, as you know means it's cold here. I've had my Lantana inside throughout the winter. For some reason I didn't expect it to bloom. I guess I was just happy that it lived. I've attached a photo of the plant with my hand for perspective but the plant is bigger than it looks. But now that spring is here or almost here, I would like to know if it will start to bloom on it's own. I was going to pinch it but I thought I would check with professionals. I look forward to hearing back. Sincerely, Stacey Turpin

Lantana plants the leaves are curling up from the sides and the flowers stems are drooping.
Without a photo and detailed information it would be hard to say for sure. I can only take guesses at this point. My best guess would be overwatering. Please include detailed information on its care and photos. This will help me to see what is going on.
In the meantime, this article will give you a good idea of their care requirements: https://www.gardeningknowhow.com/ornamental/flowers/lantana/lantana-plants.htm
This usually happens every year! One season spraying did not help? They are in a sunny spot with dome shade in the morning.
Neem Oil is a great organic solution for most pests and can help act as a fungicide.
Make sure you follow the directions on the container.
Spray plants in the early am; not during full sun.
You may need to make more than one application.

Also supposed to be hardy but mine poop out after two days - very limp. Thank you for any info and time. My camera is not "connected" to computer yet. Too old for windows 10 and have not gone to website for help yet. So cannot send pictures. But the "branches" are now missing flowers and I do not want to trim because of heat unless it's ok. Upper ones are ok and still flowering. Plant is a couple years old. Am wondering if extra "branches" are using up water so plant wilts after a couple of days.
I would hold off on pruning, except for any growth that you confirm as actually dead and brittle enough to snap off when you bend a twig.
Water deeply, not just a sprinkle. Flood the entire area under the foliar spread, to try and get six to 10 inches of water penetration into the soil root zone. Mulch the soil surface with two inches of organic mulch, like compost or fir bark mulch from a garden center. Follow up with another drenching in two days, then every week through August or September Lantana is drought tolerant once it has an established root system to gather soil moisture. Until the roots are spreading far and wide, you need to give it some help with moderate watering. Not muddy wet, just adequate to stay moist and not dry out to the extreme.
browned and curled up and a little gray looking, and are not blooming at all. What can I do to help them?

I Have a lantana in a 14-inch pot. It is its second season; should I repot it this fall or next spring, or will it be ok in its present pot? It looks great but is getting big.
Repot lantana during dormancy if the plant is healthy and roots appear crowded, using clean potting soil and a pot one size larger than the one already in use.

There are no other details; one day the plant was beautiful, the next all the flowers were dead. If this happened before I never noticed, which is unlikely. The leaves are healthy.
This can happen with excessive heat, or dry weather. I would not worry too much, unless you are seeing other symptoms. It will likely bloom again once you trim the dead flowers.
