Question
Hi, i was given 2 very large planted Angel Trumpet trees because the previous owners didn't have anymore room for them. I took them in, and put them in my basement next to my walkout so they get some sun. They're approximately 6 ft tall each. When i first got them, they bloomed like crazy. One of the trees (the one that's furthest away from the window- not by much, but it's behind the other one that's directly next to the window), the small branches are turning yellow and dying. There's no leaves on the tree. The other one atleast has leaves still. I live in Michigan so it's usually pretty gray this season. I water them once a week only. I'm scared it's dying and i can't find any answers online about the branches turning yellow, just about leaves...... Any advice?

Answer
Dear Darcie, I am assuming that you have Brugmansia which has a woody stem and not Datura which has a fleshy stem.  They are related but I think the Brugmansia is prettier and it is the one most likely to be described as a tree.  Actually most of the problem is probably just because it is winter and it's freezing in Michigan.  Here are a few tips which may help you.  First, they will go dormant during the winter, and actually it is not uncommon to have the small branches turning yellow and falling off.  I see this pretty frequently.  However, since the one that is nearest the window is growing better, I would try to get the other one more light, and actually a grow light would be a great thing for these plants.  It would keep them warmer, brighter, and help perk them up.  I would also water a bit more frequently, perhaps twice a week.  A good rule of thumb is to wait until the top inch of soil is dry before watering.  Water thoroughly, and if you have a saucer under them, make sure to empty it after watering.  Plants hate to be in standing water because it will suffocate the roots.  Also check for bugs, especially anything that looks a bit like fruit flies hovering around the plant.  Those would be fungus gnats.  You can ward off insects and diseases by treating them with a systemic insecticide/fungicide product.  One earth-kind active ingredient is NEEM oil which is available in many products.  It is a botanical ingredient and is so safe you can even bathe in it (but probably shouldn't).  Also check to see if the plants appear to be root-bound, perhaps it is time to repot them.  So basically, I don't think you have any pests or diseases, but you can be proactive on that and spray anyway, and give them more light.  I hope this information helps you.  Good luck and don't hesitate to consult me again if this doesn't appear to work.  Melissa
