Is there a best time of year to split/divide Ornamental Grass (Pennisetum)? I live in So. California. Thanks Micahel
Early spring (before the new growth sprouts) or fall (after the growing season is finished). This article contains information about dividing Fountain Grasses:
Have a potted grass. Although it is big, it is brown. Should I cut it back?
Here are some articles that will help you.
I received some ornamental grass from my sister-in-law, who was thinning hers out. I planted within hours of getting it from her and it is starting to look dead. Like straw. I don't know if it is just shock or if it is not going to make it. I don't know whether to cut it back or leave it alone? Any help would be appreciated!
The same thing recently happened to me, with some Pampas grass given to me by a friend. It started to look sorry, just like yours, and I thought maybe best case scenario I would leave it alone and it might come back up next year.
It started sprouting new growth and continues to do so!
It might be worth it to roll the dice and give your ornamental grass regular water. See if it grows a bit this year, let it winter in the ground and you may be in for a surprise next year.
Have had this plant before and recommended it to clients. Rick Darke says leaves take on dark red by July and turn wholly wine colored by September. After we moved, purchased three at a local nursery in May of 2015 and had almost no red leaves last year -- they turned brown in the fall. Thought it might be a first year problem, but now in July of the second year, only about 1% of the leaves are red. They face south and get 8-10 hours of sun per day. Just up the road, about 12 plants facing north have about 50% red leaves right now. Contacted nursery about problem and they have no idea. Have searched on Internet and found no clues. Any ideas would be greatly appreciated!
You are not alone in reports of lack of color in your Switchgrass.
My research showed many gardeners, especially in the northern climates have similar complaints of Shanandoah not living up to the hype.
If color is what your looking for the variety, Ruby Ribbons is reported to preform better.
I live in northern Ohio. Would like to know if I should cut back grass before winter or wait till spring? I planted it last spring and is about five feet tall. I've been told to just leave it as is, but others say I must cut it back before snowfall. If cutting is recommended, how much? Thank you. Brian.
We recommend cutting back in spring before the new growth appears.
I potted my blue eye grass because it was being overwhelmed by crabgrass. It had been flowering in the years before that. It was one clump and made one flower the first year in the pot. It spread to fill the 15" pot but didn't produce a single flower the second year. I am zone 6. It is wintering in my cellar. I am thinking of putting it back in the ground, but how do I defend against invasive crabgrass (without chemicals)? Or can I leave it in the pot, in which case how do I induce it to flower? The pot soil is rich with manure as I thought that might help keep the environment "marshy". Thank you.
Make sure you do not fertilize your Blue Eyed Grass. Too much Nitrogen will inhibit flowering. If the soil is very rich in compost, you can add some Bone Meal to increase phosphorous, this boost flowering. The plant may need to be divided. Lack of flowers can be an indicator of that.
Crab grass is a weed that frustrates many of us gardeners!
Hand pulling is the safest method. Perhaps if you lift the pot of rhizomes you can pull the crap grass from the soil more easily.
Here are some links for you.
