    This winter was particularly cold for most of the U.S. It is possible that it simply got too cold. Another possibility is that if the area it is growing is too wet, it cannot tolerate that over the winter. Here is an article to help you determine if it is dead or just on a slow start:

    They should. Plants in containers should be watered once a day and twice a day in temps over 85 F. This will help stop the wilting in the future.

    With many plants, it's a matter of personal taste, especailly with ornamental grasses. However, a general spacing would be 12-18 inches for purple fountain grass, 6-8 feet for star jasmine, and 9-12 inches for the heather.

    They may need more water. Try increasing their water. In containers, they should be getting water daily.

    It may also be an issue with the wind. If they are in a windy location, this may be knocking the stems over.

    It helps to know what zone you're in. I'm in zone 6b (middle-plant zone for the USA), and our fountain head never flowered until late August-early September. That was fine with us, since we bought it for autumn colors anyway. Until I read your question, I assumed no one got them earlier. lol

    I would say yes, go ahead and prune it back but merely give it a good trim rather than a hard prune. Save that for late winter/early spring. Here is an article that you may find helpful: https://www.gardeningknowhow.com/ornamental/foliage/fountain-grass/fountain-grass-pruning.htm

    They may have too much nitrogen. Try giving them some phosphorous to balance out the nutrients again. You can use bonemeal for phosphorous.
