I have an indoor yucca plant that has yellow, weak leaves. I read that it is due to not enough light and probably over watering. Is there anyway that I can save it?
With the yucca, water it only when the soil dries out and get it more light. If it gets the right kind of care, it should rebound and become healthy again.
My yucca is about 12 years old and has been an indoor plant. I have pruned it and would like to plant it out onto my lawn. Will it survive the winter?
Yes, you can put your yucca outdoors and it will thrive, even in winter. These are extremely hardy plants. Here is an article that you may find helpful: https://www.gardeningknowhow.com/ornamental/foliage/yucca/caring-for-and-landscaping-with-yuccas-outdoors.htm
My yucca plant does not have needles at the end of the leaves. I'm not sure what type this is but need to know how to maintain it. The plant is in my screened lanai and gets west sun through the screening.

I have got a rather large indoor (I think it's indoor; how do you tell the difference?) yucca. I am not sure how tall it will grow and the pot it is currently in is already quite large and hard to shift. I generally put it outside during summer and then bring it back in for winter. 1. How tall will it grow? 2. It has new leaves sprouting off the trunk lower down, do I/can I remove these for new plants? 3. How can I tell whether it is an out/indoor plant?
Most varieties can be grown indoors or outdoors, so this really isn't relevant as the care is basically the same. Here is an article or two that you may find helpful: https://www.gardeningknowhow.com/ornamental/foliage/yucca/yucca-plants-care-and-pruning-tips-for-pruning-a-yucca.htm

I got a Yucca plant for my bridal shower a few weeks ago and I just don't have enough room for it indoors. I would like to plant it outside but I need to know if it will survive a Nebraska winter and whether it is a sun or shade plant.
They are sun plants, but whether it will survive outside or not depends on the type of yucca it is. If it was given to you with the intention that it be a houseplant, it likely is not suited for your winters and needs to stay indoors.
I have a yucca plant too big for the room. Is it ok to chop it off at about a foot? Will it sprout or will it die? Advise please.
Yes, you can prune the plant back if it is getting too large or unsightly. The part of the trunk that does not have leaves will not regrow leaves if you prune the leafed part away, but it will often sprout new branches. It is very difficult to kill these plants, as they are very hardy.

I live in Spain. I have a yucca plant which is now flowering. The plant is about 4 years old. It is in a 20-inch concrete pot. The plant is about 4 feet tall. I was wondering if it was possible to collect seeds at a certain stage of its flowering period?
