What Happens if Pompas Grass Was Not Cut Back in the Spring and Plant Starts to Grow Again
One garden task almost universally recommended for the terminate of winter or early spring is to prune ornamental grasses close to the ground. However, as a laidback gardener, I object to the generalization. Isn't there any way of avoiding this job? Let's look and see.
Evergreen Grasses
First, some grasses are evergreen (or everblue): blue fescue (Festuca glauca and others), blue oat grass (Helictotrichon sempervirens) and most sedges (Carex spp.), among others. Since they are evergreen, they don't normally demand pruning. Perfectionists can always pull out any dead or yellowish leaves ane by one (wear rubber gloves: the dead leaves will be easier to grip onto) in order to "clean" the constitute, only otherwise they volition wait pretty good on their own with no special care at all.
Of course, sometimes after an unusually harsh winter, the foliage of even evergreen grasses tin can be severely damaged. If so, practice cutting them dorsum to about 3 inches (seven.five cm) from the ground. This is for emergencies only, though. They don't appreciate harsh pruning and this could weaken or even impale them if yous repeat it annually.
Deciduous Grasses
The bulk of normally grown ornamental grasses, however, are deciduous. Their foliage dies and turns brown in the fall, but frequently remains standing. Moreover, their winter result, with arching leaves and feathery plumes nevertheless proudly erect, is 1 of their main attractions. But by the spring, the leaves are starting to collapse and the beautiful flower spikes accept begun to crumble. It would seem that pruning is an absolute necessity!
But not so fast!
In nature, nobody prunes deciduous grasses. New leaves just sally through sometime, tired ones and eventually embrace them up. And the old leaves eventually decompose and disappear, usually the same year. Remember likewise that the very best compost for whatever constitute is its own dead leaf! Assuasive the old foliage to remain intact volition slightly wearisome down the speed at which the grasses seem to green up, but in no way harm them … and an unpruned plant will soon catch up to a pruned 1.
If your ornamental grass is in the back of the garden, where the transition period—where you see a mixture of light-green and brown leaves (which can last up to mid-July)—is not and so visible, you can only walk away and let the plant take care of itself.
In spots where the grass is highly visible, even so, you may want to cut the grass back in early jump. Merely there are still a few tips to help make the task less arduous.
Making Pruning Easier
Beginning, before cutting the plant back, use a piece of string to adhere the stalks together, pulling them tight to class a sheaf. You may prefer to attach taller grasses in two or more places, giving a column event. This fashion, you lot won't have grass leaves in your line of vision as you prune and they'll all be nicely attached in one single package, making for easier removal one time y'all've cut them down.
All you accept to do, and then, is to cut the sheaf off about 4 to 6 inches (10 to 15 cm) from the ground. Yous tin can practise this with pruning shears, of course, only so yous'll take to spend a lot of time bending or kneeling, a difficult position for older gardeners to maintain. Also, you'll before long discover many grasses have precipitous leaf edges, not something you want to stick your hand into.
Instead of pruning shears, try cutting your grasses back with a hedge trimmer or small chainsaw (the fastest method) or a string trimmer (slower simply still effective). This takes trivial fourth dimension and y'all can often do it without having to kneel.
Afterwards, run the sheaf through a shredder: chopped grass leaves make a bully mulch!
Mother Nature's Clean-Upward Method
But at that place is an even lazier manner to prune deciduous grasses: set them on burn down!
In nature, tallgrass prairies—the natural habitat of most of our ornamental grasses—unremarkably burn every ane to five years. Fire is therefore part of their natural lifecycle. Indeed, without fire, there would be no prairies or steppes: trees and shrubs would take over and the land would eventually become scrubland or forest. Burn cleans out dead stems and leaves, kills invading plants (notably tree and shrub seedlings) and fertilizes the soil. And grasses themselves are non adversely affected by burn: in fact, they have evolved to tolerate burn down and even profit from this "natural pruning." A grass that burns to its base will grow back much meliorate than a grass that is cut back. Try information technology and see!
Of course, in this solar day and age, it is no longer possible to burn grasses in well-nigh urban areas. Cheque with your municipality to find out what the restrictions are.
If you do have the correct to practise so, any burning should exist done in early leap, when the basis is still quite moist. Furthermore, for safety reasons, wait for a windless twenty-four hours and, earlier starting the burn, h2o all nearby non-grass plantings, soaking their leaves and stems. And stay nearby, hose in hand, to extinguish any stray spark.
To anyone who might mutter that burning can't possibly be environmentally friendly, think once more. This is the well-nigh natural and environmentally friendly method of all, office of Mother Nature's program. How tin can you lot go incorrect when you practice what Female parent Nature intends?
