Hi, My marigolds were doing fine in spring and early summer but recently I observed them drying up like the picture shown. One plant completely dried out and other one is drying from bottom. I live in texas so it is too hot and humid here temperature 40-45 degree celcius. But it also rains frequently. Is this due to root rot or heat. Please give me the solution to this problem
They tolerate heat just fine, but that soil looks VERY wet. Does that container have drainage to allow extra water out?
I can't tell how big the pot is but if you live in Texas you probably need to water twice a day. However, the soil looks saturated. Let the soil dry between waterings. Try cutting back the dead looking foliage and see if it rebounds. If not, most likely a fungal infection has set in. Curing those plants will not be an option. It would be best to get fresh soil and try again with new plants.

Unfortunately, your photo did not come through. I am unable to see the issue at hand.
These symptoms can be caused by a handful of things. Usually, lack of light or pH imbalances, but can be caused by nutrient deficiencies too.

I’m a very new gardener and my question is if i have a marigold plant and live in a tropical climate. By the time that the marigold die because it being annual, will there be a new marigold that already bloom and have flower that grow from self seeding to avoid empty garden. Or does the marigold die and ill need to wait for the seeds to grow and mature?
It is likely that marigolds will self seed in succession. You may still have some bare ground or flowerless plants for some portion of the year, but they will likely keep the area filled out for the most part.
The new generations will not likely resemble the parents, or will not likely flower as vigorously as the parents, but they will self seed none the less.

They would be started from seed.
They are best planted in spring, either started indoors before the last frost date or started in the ground after the last frost.
Growing them now would only kill them with the first hard freeze.

We just moved to a home in CT and a lust bounty of marigolds have come up in our front yard. I didn't plant them and I know they are usually not perenials. Should I cut them back for the winter or just leave them until the spring. I'd like to encourage them to come back again each year.
Just leave them and they should go to seed and return.
They are one of the annuals that reseed freely. You can also save some of the dried flower heads to be sure you have some seeds for next year.

The best way to encourage the return of marigolds is to save seed and replant it in spring. It does not self-sow but is easy to grow from seed indoors or out. It is easier to pull the plants after they die back than to deal with the mush they become over winter. However, the choice is yours. Another option is to cut them into pieces without pulling them out, leave the leafy parts on the soil and they and the roots will compost in place.

I got this plant two weeks ago, I don't know its name. Its flowers are turning brown and its green leaves are drying and falling; I think it's dying - I don't know how to take care of it. Does it need to be watered following a schedule? Should I put it in a sunny place?
It looks like a marigold. And yes, it needs a sunny place and regular watering. If deadheaded, they will bloom all season. They also reseed freely.

I live in Ft. Myers Fl. Thanks
You can plant marigolds anytime after the danger of a frost has passed. They are annuals that often reseed, so once you have them, watch for them to come back. Or you can collect the seed and sprinkle them out the next year.
You can plant them in containers or in the ground in a sunny site with well-draining soil. Happy planting!
