What should I do with my angel trumpet tree this winter? It is planted in the ground outside and is doing awesome! It is huge and is full of blooms! It is too big to bring indoors for the winter.
Angel trumpet is totally a tropical, and not hardy below 40degrees F. In a more northerly climate such as yours, people usually grow them in pots. They're pretty tough, however, so you can try digging it up and putting it in a pot, cutting it back, and dealing with it as recommended in this article: https://www.gardeningknowhow.com/ornamental/trees/brugmansia/prune-brugmansia-trees.htm

I have an angel trumpet and during the winter I cut it back and place it in a cool dark spot. It has been in the same large pot for 3 years and I would like to change the soil. When is the best time to do this and do I need to prune back the roots? Thank you for your help.
I would recommend repotting in the spring when you bring it back out. This is when it is the most active in growth and will be best able to handle repotting. If you are moving up to a larger pot, then there is no need to root prune. But, if you are staying in the same size pot, you can remove up to 1/3 of the root system at that time.
Even though I'm in Texas, Zone 8a, I've moved all my outdoor plants into our greenhouse that we just put together. Since doing this about a month ago, my Angel Trumpets have just gone crazy with blooms. Since I'll be keeping them in the greenhouse until probably the first signs of spring, do I need to prune them? I have them in very large pots.
Almost forgot, thank you for the link.
I most definitely don't want to prune them because they are so beautiful. I've still got about 30 or so blooms yet to open. This is our first year with a greenhouse so I wanted to make sure that even though they are in the greenhouse that they didn't need to be pruned. I would imagine then that the same will hold true for my Hibiscus and Bougainvilleas that are in there.
Why would you want to prune them and lose those gorgeous blooms? You can do some pruning when the flowering slows, but with a light hand, and you should be able to keep it flowering right along.

I purchased 4 bareroot angel trumpets In March 2016. They sprouted leaves and are 1-4 feet tall. Now I am noticing brown tips on all 4 and 1 started dropping leaves in July. I have not fertilized them yet because I am afraid to burn them off. They are in a pot. What am I doing wrong? Thank you for your help.
Make sure you are watering adequately in the warm weather.
Your plants need daily and even twice a day watering in warm weather.
Also make sure the soil is well draining, and that the roots are not standing in water.

I have my first Angel Trumpet, which bloomed beautifully this summer. It is in a large pot so I carried it inside for the NJ winter months. It lost most of its leaves but has now started growing again. It is in a window with some afternoon filtered sun. The plant is about 5ft. tall with a Y branch almost at the top. I would love to prune this but am afraid of killing the plant. There are 2 long 2ft. branches from the Y. Please help. How and when can I prune this and can I root the pieces that are cut off?
You should hold off pruning now, as it is not in a dormant period.

I brought my plant in the house over the winter. It is a little over 3 feet tall. The branches are green, but not getting any leaves on them except close to the bottom. Do I need to prune it back to get it to produce more leaves?
It would not be unusual for your plant to show little new growth while indoors.
I would continue to care for the plant and wait until you move it outdoors to give it a pruning.

I am seeing yellow coloration on Angel Trumpet plant. Also the leaves are getting eaten by something. I don't find any bugs visually.
Pests are often small and difficult to see.
I would treat the plant with Neem Oil.
