01748Q.I Have Tall Ornamental Grass. It Did Not Come Back Up This Spring. What Happened?
We cut it back every fall. This past fall I split some of it because it was too big. Where i transplanted it has come up but where the original is planted it has not come up. It's still cut back with no new growth? How can I fix this?

Certified ExpertA.Unfortunately, the original mass may have sustained too much damage to come back. Generally, cutting back in fall, instead of early spring, will decrease the lifespan of the grass. Most ornamentals prefer a spring pruning. You may need to divide out a segment to replace the original, once your divisions are large enough.

Certified ExpertA.Fiber optic grass needs constant moisture. Without it, they will turn brown and eventually die. You can try cutting it back to about 2 inches. If it's still alive it should regrow.

I have grasses that need to be moved now. Would it be ok and should I cut the foliage down any. Thank You , Alan

Certified ExpertA.Doing so will need to be done during dormancy. Late Winter or early Spring will be most appropriate. This article will help:

10024Q.Which Ornamental Grasses Would Work In Large Pots In New York City?
Our building in the Upper West Side has some large pots in front. They get direct sunlight for just a few hours a day. Sometimes the super of the building remembers to water them but often he does not. They are filled with dead or dying boxwood plants right now. We would like to replace the box with ornamental grasses on the assumption that they could be more drought resistant than the unfortunate boxwood. Could you suggest any ornamental grasses suitable for planters in New York that would survive the climate and the stress of intermittent watering - and which would look reasonably attractive throughout the year? Many thanks in advance for any help. Nick Manning

Certified ExpertA.You could try some of the more ornamental cultivars of Miscanthus sinensis, such as the one called 'Rosi'. It is suggested for container, as long as you control its spread. They can get a bit invasive without control, escaping its original location.

Certified ExpertA.I find that Carex is a great container grass that is drought tolerant as well. These articles will offer other suggestions that may work:

September 12, 2023A.Thanks so much for such a prompt response. Carex (sedge if I understand correctly) is not particularly ornamental I think. Could you suggest anything for a planter that would survive the New York winters and looks attractive (seed heads etc.)? Thanks again.

September 22, 2023Q.Does Blue-eyed Grass Regrow In September After Drying Dead In August?
Our summer was so hot that the Blue-eyed grass all dried up and the dead blades were pulled out in August. I see what looks like about 2" growth of grass. I am wondering if this is the blue-eyed grass or just weed grasses?

Certified ExpertA.It probably won't bloom again till spring. The leaves gather energy that is stored in the rhizomes. Browned foliage can be cut back at the crown.
You may have some weed grasses filling in.

Certified ExpertA.Both are acceptable and have their pros. Many choose to kill them as they emerge in spring. It is easier to kill off young starts, and will ensure that you get them all. I would do so, as well.
