I received a large mum plant as a gift. I would like to plant it outside. When and how should I do that? Thank you.
Simply put them in the ground as deep as the pots they came in or transplant them into new pots. These plants need well-draining soil and sunshine. Water well after transplanting. For those outdoors, here is an article about overwintering them that you may find helpful: https://www.gardeningknowhow.com/ornamental/flowers/chrysanthemum/wintering-mums.htm
Why are my mums not blooming? They are big and bushy, but have no flowers or any signs of them. They are several years old.
The soil could be lacking phosphorus, which is needed for blooming. You can try a phosphorus-rich fertilizer or adding bone meal to the soil.
When this bush, or whatever it is called, dies down what do you do? Contact me at catherineL2000@yahoo.com
From bhg.com-Overwintering. Prepare mums for winter after the first hard frost. Mulch up to 4 inches with straw or shredded hardwood. Fill in around the entire plant, spreading well between branches. Pinch off dead blooms to clean up the plant, but leave branches intact. Mums have a better chance of surviving if you wait to prune old stems until spring. As soon as the weather warms, pull away mulch to allow new shoots to pop up.
I live in Florida and we had a considerable amount of rain previously which led to most of my mums dying, I think. I've only had this batch of mums for about 6 weeks and although they were only around for the tail end of the rains, all the flowers have turned brown. What causes the flowers to turn brown? Do you think it was caused by root rot D/T over watering? How can I keep the flowers longer?
Depending on the age of the plant, the temperatures and sunlight conditions the blooms will fade at different rates.
Keeping the plant dead headed will help encourage more blooms.
Pinching plants back after blooming periods will help with later blooming.
Mums do need well draining soil, so if the roots remain in soggy soil they certainly suffer from root rot.
You would see the entire plant show signs, not just the flowers.

Live in Texas and it usually doesn't get cold enough for my mums to die back. Can I still cut them back? Guessing early spring.
The best time to prune or trim them back is right after they are done blooming.

My mums are from last season. They are now very leggy, and some are starting to bloom. Should I cut them back to make them more bushy? They are not very attractive.
I would cut the plants back now, despite the fact that they are just budding or blooming.
This will help shape up the plant for the summer and should help result in a healthy, and pretty plant for the Autumn season.
Here is a link to refresh you on the care requirements.

I have a big beautiful scarlet red-colored mum that comes up religiously every year. Well in the summer I wanted to do something new with the flower bed it's in, and I put down cloth and lava rocks! Big mistake! My mum absorbed too much water! Now it's not growing. It concerned me because by now it would be almost ready to bloom and hasn't grown at all. I removed the cloth and rock. Any way to save it? Please help! Thank u! - Natalie,WV
This article gives advice on how to help stressed plants. You could also try giving it some temporary shade while it recovers.
