Dividing decorative grasses

Question

Is there a best time of year to split/divide Ornamental Grass (Pennisetum)? I live in So. California.

Thanks
Micahel

Answer 1

Early spring (before the new growth sprouts) or fall (after the growing season is finished). This article contains information about dividing Fountain Grasses:
