Q. Is it OK to divide my ornamental grasses now (end of October)? I am so busy with other gardening chores in spring that I never seem to get around to it, and they are dying out in the center.
A. Most of the ornamental grasses commonly grown in our area are warm season grasses that should be divided and moved only in the spring. The same goes for the native grasses that have become popular in recent years. These include switch grass (Panicum virgatum), big bluestem (Andropogon gerardii), little bluestem (Schizachyrium scoparium) and Indian grass (Sorghastum nutans).
If you divide and move them in fall, there is a risk of losing them. They are entering winter dormancy, and probably will not have a chance to re-establish their root systems before cold weather shuts down root growth altogether. Another factor is that their energy reserves are low because they have just finished blooming and setting seed. They may not have the vigor to recover if you divide or move them now.

Q. I really like Red Fountain Grass but hate purchasing it every year. I've never seemed to be successful getting the seeds I save from my plants to grow the next year. Is there something I should be doing differently?
A. Red fountain grass (Pennisetum setaceum ‘Rubrum’) is propagated by division rather than from seed. That explains why it is more expensive than many other annuals. Red fountain grass typically sets sterile seed, which is why you have not had any luck getting it to grow. You can dig your plants up in the fall and pot them up in large containers, to try to overwinter them indoors. An unheated attached garage or crawl space where the temperature does not fall below about 40 degrees would be ideal. Cut them back and water them thoroughly before putting them in for the winter. Leave them alone until late April. Then you can pull them out and divide the clumps if needed. Pot the divisions up to get them growing before putting them back in the garden after danger of severe frost has passed.
Grow in partial shade. Variegated leaves. Can become invasive. Height 2 to 3 feet.
