I live in Alaska and have had a giant Bird of Paradise plant for years. I woke this morning to find what appeared to be a perfectly healthy leaf broken off at the base on on the floor. My question is, is it possible to put this in water to root it and replant? It really is an odd occurrence. Any way to wrap the leaf in a potting soil medium to get it to root?? Thanks for your help.
Everything I could find on giant bird of paradise (as well as the common form), says to propagate by division or seed. You could try dividing your clump, and divide out the broken piece and grow it in soil with the broken end recut. I would try rooting the leaf, too. Recut the end of it at a 45 degree angle and place it in a jar of water. Replace the water every couple of days to discourage bacteria buildup. Or, you can pot it in potting soil, water, then cover with plastic to create a greenhouse effect. Check the soil periodically and add water if dry. Vent the plastic every couple days, too, to release some of the humidity. Here is more:
Can I save it? When I got it there were 2 stems about 18 inches tall. Each had a curled up dead dry leaf. I trimmed them and started to check the dirt. Absolutely no roots!
Most sources recommend division or seed for propagation, but it never hurts to try from a cutting. It looks somewhat dark on the end so cut off just a little, and dust it with rooting hormone if you have any. Then pot it in good potting soil. Do not water for two or three days. Then follow the instructions for planting a rhizome in the article below.

Should I have kept them in mouse. Directions said sunny place and I assumed outdoors. Was it possible that it was too cold at night this time of year
Yes, in house would have been ideal. They will prefer it about 85 F for germination. This article will explain:

My bird of paradise has a flower bud which does not look like it is going to open should I leave it or cut it off .This is the first flower bud that I have the plant is producing new leaves & I think it might be getting another bud I’m sending a picture Hope you can let me know what to do please ?
I wouldn't be in a hurry to cut it off. It may bloom. If it starts turning brown and declining, then you can remove it. Here are some growing tips that may help:

The plant is about 6 ft tall, came from Florida to my home in Michigan about three months close to a large south facing window. It has pushed out four large new leaves since I’ve had it. I use a water meter to make sure I don’t over water and watered it when at least the top two inches were totally dry during winter but am watering it now when almost dry. I had a humidifier during winter but now it is humid naturally in warmer weather. I don’t fertilize yet since the greenhouse puts slow release in it typically and I do see the little green beads in the soil. I don’t see any signs of pests and the rest of the plant looks vibrant. Also should I cut them off?
It is probably a form of rust, which is a fungal disease. Go ahead and pull off the affected leaves and it may not spread. If any leaves dropped onto the soil, remove those too. Apply Neem oil to the rest of the leaves. Too much water is often the issue.

I've decided to save my potted tropicals by bringing them indoors over the winter. I don't think I have enough natural light in my living room, so I've decided to grow them in my dark basement under artificial lights. I have a bird of paradise that is 4-5 feet tall, while my alocasias and bajsoo banana plant are 3 feet tall. I have a sago palm that is 2 feet tall. What type of artificial lights will I need, how long do I keep the lights on daily, and how close to the top of the plants should the lights be? Should I fertilize monthly?
When overwintering plants, the goal is to get them through the winter, but not expect flowering. Does your basement stay above freezing, and more ideally for tropicals, about 50 degrees F? You don't need to fertilize during the winter. And just give them enough water to keep them alive. Overwatering can quickly kill a plant that's overwintering.
