I have some perennial grasses in my flower bed that are not hardy for my zone. I would like to at least attempt to winter them over. Any suggestions other than the norm of mulching?
Mulching is one of the best ways to protect plants over winter. It also depends on the type of grass and your location. For instance, unless you live in a relatively warm climate, warm-season grasses won't tolerate cold. In fact, in cooler climates, they are often treated as annuals or overwintered indoors. If this is the case for you, then you could try digging up the plant, potting it and leaving it indoors over winter (watering once a month). Once srping returns, you can plant it back outdoors. Unfortunately, you might need to replace it in the event that it doesn't show signs of life.
Can I cut my ornamental grasses for winter? I live in Zone 9.
Yes, you can cut your ornamental grass back now.
I have several types of grasses and I let them go last fall and would like to cut them back now. I live in Oklahoma and was told they would winter over and to cut back when new growth appears. No new growth has appeared yet, but we're having an early spring. They are brown and dead looking. Am I ahead of myself? Should I wait till new growth appears or go now?
When cutting back ornamental grass, you should do so in early spring, as its foliage helps protect the plant throughout winter. However, it is common to have inconsistent growth with these grasses, especially fountain grass. Many of the warm-season ornamental grasses won't start growing until mid to late spring, or even early summer. If there are still no signs of life by late spring/early summer, chances are good that the plants did not survive winter and will need to be replaced.
Is it true that mice will nest in ornamental grasses? I want to plant grasses in a flower bed at the front porch entrance but fear them coming into house during the winter. If yes, is it true that lemongrass will deter mice if planted next to grasses?
While it is true that mice will occasionally nest in garden spots offering lots of shelter, including grasses, it is highly unlikey that they will take up residence anywhere there may be lots of traffic--such as the front porch where most people go in and out frequently. If, however, mice should become a problem for you, this article has some suggestions that should help: https://www.gardeningknowhow.com/plant-problems/pests/animals/garden-mouse-control.htm
I have ten tall (14-foot) grasses. Retired now and cutting them back every fall is too much for me and the township hick-ups when picking up all the waste from these. Poured vegetation killer on all off them in October. Some are 5 foot in diameter. Do you know how far they go into the ground? I have cut them low with a chainsaw, so they are 10 inches from the soil right now. So the question is: how do I remove them?
If they are still alive, your best bet would be to dig them up and then treat the area with weed killer. To be honest, you may want to place an ad on CraigsList saying that someone can have them for free as long as they dig them up. You will likely find several people happy to do the work for you.
Are mondo and monkey grasses pet friendly? Thanks!
The berries are mildly poisonous. Fortunately, they are not life threatening if they are eaten, but do cause stomach upset and diarrhea.
I planted some annuals in 24-inch planter using garden soil. Will they be ok? Also, what ornamental grasses could I plant where I live that will come back in the summer?
It is actually better to use organic rich potting soil rather than using regular garden soil. Regular garden soil can compact and harm the roots while potting soil will stay aerated, which will give the roots room to grow well. You can easily remedy this, however, by mixing in some potting soil or organic matter (like compost or peat) into the current soil in your pot. With adequate care, the plants should do fine. There are many ornamental grasses suited to your region. Here are a few suggestions: Maiden grass: https://www.gardeningknowhow.com/ornamental/foliage/maiden-grass/growing-maiden-grass.htm, Japanese forest grass: https://www.gardeningknowhow.com/ornamental/foliage/japanese-forest-grass/golden-japanese-forest-grass.htm, Northern sea oats: https://www.gardeningknowhow.com/ornamental/foliage/northern-sea-oats/northern-sea-oats-grass.htm, Fountain grass (look for one particularly hardy to your area). In Zones 5-9, fountain grass is considered perennial. However, they seem to respond better in the warmest areas of Zone 5. They can survive in the ground and come back as long as it does not get colder than 20 F.
