Q. It’s fall in Utah and my fountain grass just turned brown. It’s has been in the ground for only 2 1/2 months. Do I trim it now o

r in spring? Do I cover it for the winter or leave it as is? Do I water it or feed it now?

No fertilizer is needed now. You should cut it back in late winter or early spring.

Q. I planted a Hameln dwarf fountain grass last spring, this spring it’s still brown. I live in zone 5, just wondering if my grasses

have died or if I need to wait for the weather to get warmer. Suggestions? I planted 3 Hameln grasses about ft apart from each other. It’s in well drained soil, gets enough water, but never saturated. These plants get full sun. I also have the same grasses in front of the house that’s xeriscaped, and they’re also brown.
While, I was taking the photos I noticed there was some green at the roots, and the stems are pliable not stiff and breakable just “brown”.

Fountain grasses are warm season grasses and will not green up at the same time your lawn does. Cut your grass down if you haven't already done so. It will be coming up when weather warms.

Q. Should we cut back our white fountain grass?

We just bought and planted white fountain grass and they are very droopy. They were y’all with some browning when we bought them.

Q. Why are the hitchhiker seeds that come off of fountain grass a hazard? Propagate where you don’t want it?

I noticed the seeds “hitchhike”. Any soft material that comes by grabs a bunch of the seeds of the mature tops and they ride to wherever. Do they also blow all over the place and start growing in your lawn?

Yes, this is how they are meant to propagate. By any means necessary. They will start up anywhere that they can as long as the environment allows for it.

If they area is mowed frequently, or managed by hand, then you can control most instances before they are old enough to reproduce.

There are several species that are called fountain grass. The African grass, Pennisetum setaceum in considered invasive, particularly in the western US. Pennisetum alopecuroides or Chinese fountain grass is listed as invasive in some mid Atlantic areas. In total, there are 6 Pennisetums listed as invasive. However, I'm not convinced we are talking about the same plant genus. Pennisetums produces a huge number of seeds that spread via wind. They do not have burs or awns for hitch hiking. A number of other plants do , however. Some are native plants, some invasive. Perhaps you can start a new post with a photo of the plant in question. A web search for plants invasive in Ohio may turn up the information you are seeking.
