Our Western sword ferns have been planted so that the crown or center area where new fronds emerge is 1 to 2 inches higher than the soil it is planted in. Is that too high? Thank you, Paula Haynes
What is the best time of year to plant autumn fern in Raleigh, NC?
You can plant in spring or fall.

I asked about transplanting ferns in the fall and did not get any information, helpful or useless, about doing this task in the the Fall. I have to move a large number of ferns that have "naturalized" where I don't want them, and plan to move them to my wooded backyard in the next week and wish to minimize the number of casualties.
They will do best if you transplant them in early spring, right before the new growth comes out. Late dormancy is the correct time to do this. You can, however do this at any time. Just have caution, as you will likely lose a few if they are actively growing when you transplant.

Three elements are key: only transplant on cool days, preferably cloudy ones; move as much of the rootball as possible; and water every few days for 1-2 weeks and then weekly until the ground freezes. Even after the fronds go dormant, the roots keep working to get established. Plant dehydration going into winter is a cause for winter kill.
How to prune Japanese painted ferns
Typically, you shouldn't have to prune these often. I would only remove dead or dying leaves. If you decided to prune it, I don't think you would hurt it, but you don't have to.

Hi! We have 5 ferns in pots outside ---they look great! Are way too heavy to move... What do we need to do as colder weather approaches? Can we somehow save them over the winter?
First, you must identify the type of fern that you have. This will help you to decide whether or not they will be suited to survive in your area. The type of fern they are will determine what steps should be taken to ensure their survival.

Do Holly Ferns like their leaves (fronds) getting wet when watered?
It isn't normally a problem to do so. If the area remains too humid, then this could cause a mold issue. But in most circumstances it will be fine to get them wet.

Do you have any recommendations for a room humidifier for my houseplants during winter? And , could you please tell me what makes purple leaves turn reddish and die on a purple heart houseplant? Thank you very much.
A humidifier would definitely help them out. It isn't completely necessary for them to survive, but they will be much happier with it. I believe this to be the cause of the issue with your tradascantia, also. The leaves sound like they are beginning to dry out. Just a small dehumidifier would be enough to keep them happy.
