Buffalograss III

So, for the person who wants to own one, what have I learned about caring for buffalograss lawns?  Who should have one?  How do you keep the weeds out?  What problems may develop?  What about watering?

As I've stated before, buffalograss is a low-maintenance grass, but not a no-maintenance grass.  When I first put it in, I followed instructions to wait until the average daily temperature was above 80F, I planted it in the correct concentration and then mulched it sparsely with straw to help conserve the moisture, and I kept it watered well.  The result was a thinly-covered piece of ground around the house that filled in pretty well by the end of the summer, but also developed more than a few weeds.  I controlled these by regular mowing in the first two years, but I didn't apply any extra water or fertilizer to the lawn.

By the third year, there were areas of the lawn that were unhappy and became sparse.  I wasn't able to find symptoms of disease as the cause, but resorted to applying a little fertilizer and watering these areas and even a dense-head like I am could tell that the grass loved the extra treatment.  So I've settled now into providing a nice bit of high-nitrogen fertilizer in early June, after the grass has greened and is growing well, at about half the rate recommended for a fescue lawn.  That seems to encourage it to keep a very dense, even turf appearance and helps it to be just a little more green.  And in the height of summer here, late July and early August, if we've gone several weeks without rain and the temperatures have been over 100F, then I have been known to give the front yard a little watering every other week or so. That keeps it from going entirely dormant and it will green up again quickly when the September rains hit.  Usually the right time to water is about when every one else in town is watering on a nightly basis and my co-workers begin complaining about their water bills.

Weed control is another aspect of buffalograss care that can't be neglected.  There are commercial herbicides that are labeled for use on buffalograss during the growing season, but I haven't used them.  Instead, I've been happy with a program of applying Barricade crabgrass preventer at the recommended time in early spring.  To control growing weeds, you can either burn the buffalograss each spring (see below), or you can spot-treat any weeds that green up (dandelions and other broad-leaf weeds) while the buffalograss remains dormant.  As long as you are sure the buffalograss is still dormant, you can use about any herbicide necessary, including Roundup.  Once the buffalograss greens up, I simply hand pull weeds or keep them mowed down.   As far as insect problems on buffalograss, I've never seen any.  My neighbor occasionally treats his buffalograss areas for what he was told was some chinch bug damage, but I'm not sure whether he actually has chinch bug troubles or whether it was just an excuse to sell him some insecticide.  He has a different variety ('Cody') than I do ('Tatanka') so it is also possible that I'm just too cynical about plant store representatives and  'Cody' is simply more susceptible to cinch bugs than 'Tatanka'.

And one last tip; buffalograss loves to be burnt annually.  When you think about it, that's hardly surprising since it evolved in the face of the frequent prehistoric burns that kept the prairie free of trees.  I believe that the removal of the dead understuff helps the grass to thicken up and it seems to green it up faster as well.  And the weeds that have started to grow simply hate being burnt and they disappear, never to be seen again.  Perhaps the positive effect on the buffalograss is merely a result of wiping out the competition, but I prefer to think that it is thanking me for recognizing its true nature and history.  Because buffalograss has a soul that you will recognize if you take it for your own.  As Todd Rundgren sang, "Like buffalograss, you crawled across my heart, oh like buffalograss wrapped yourself around my heart."

Striking Serendipity

For a brief interlude from alternating my buffalograss manifesto and some native wildflower pictures, but in line with the Native Prairie Weeks theme I've started, I thought I'd squeeze in a little serendipitous combination that is starting to "pop" out in my garden.  The picture below is a young start of a variegated 'Fiesta' Forsythia (Forsythia  x intermedia 'Fiesta), that has had its space invaded by a self-seeded Butterfly weed (Asclepias tuberosa).  I started the 'Fiesta' a summer ago as a cutting from another larger specimen and I had placed it on the end of a row of lilacs, intending it to become a summer focal point against the dark green foliage of the lilacs.  I guess that stirring the soil exposed long-buried seeds and the Asclepias won the rapid dash to the finish line.  Over time, the 'Fiesta will be taller than the Asclepias and the latter will become an accent to the former, reversing the current imbalance in height.  Regardless, I don't think I could have picked a better plant to bloom and compliment the light yellow foliage and variegation of the 'Fiesta'.  Sometimes, maybe all the time, Nature knows best.

But doesn't it make you wonder?  That it would coincidentally be Asclepias, named for the Roman god of medicine and surgery (Asclepius) by Linnaeus himself, that would so often grace the garden of a surgeon?  Or that this combination, chosen for its pleasurable appearance by and presumably to God,  also is pleasing to we mere mortals who can only admire the genius of the natural world?

June Native Wildflowers II

Oh dear, a potential obstacle has developed that might affect my plans to leave areas of the yard unmown so that I can "cultivate" the native prairie forbs this year.  I was walking the back garden last night with Mrs. ProfessorRoush and the Primary Rabbit- and Snake-chaser, when Mrs. ProfessorRoush suddenly realized that I have been merely cutting paths through the back yard and was planning to allow most of the native prairie grass to grow for the summer.  She was, to put it mildly, neither impressed by my ecological correctness nor amused when I tried to change the subject by getting her to notice a new rose.  Mrs. ProfessorRoush seems to care less about the potential for beautiful prairie wildflowers than she does about increasing her potential for encountering snakes, mice, chiggers, ticks, and other natural creatures.  So, enjoy the pictures below, because I don't know how long I'm going to be able to let these plants bloom!



A yellow wildflower that is just now coming into bloom are my stalwart Black-eyed Susan's (Rudbeckia hirta) that self-seed through my back patio bed and over the prairie.  In fact, the pictured flower just opened and is the first of many to come this year.  I have a few of these every year, and they bloom dependably through July, but seem sometimes to get a little mildew and the stems and leaves are eaten occasionally by an unidentified insect pest. These cheery little guys seem to be more prevalent than normal this year.  I can understand the cause in the patio bed since I haven't yet mulched that bed this year, trying to encourage growth of the self-seeders, but I can't explain why they're increased on the prairie. 

The delicate, but drought-resistant, Missouri Evening Primrose (Oenothera macrocarpa) is always a welcome sight, as is the related white form of the Showy Evening Primrose (Oenothera speciosa).  These almost translucent flowers open at sunset and close by mid-morning, so the best time for viewing them is while dew still coats the grass.  They face upwards when they first open, allowing themselves to be pollinated by a night-flying moth, and then turn their faces downwards after pollination, hanging their heads in apparent embarrassment after the sex act has occurred.  I guess the flowers at the right were still virgins.

The not-so-delicate Buffalo Bur (Solanum rostratum) will grab you with it's prickly leaves and spiny calyces (burrs) if you aren't watching out carefully.  This nightshade family member, also known as "Kansas Thistle," thrives on disturbed ground and is extremely drought-resistant and an aggressive self-seeder.  At maturity, the main stem breaks off and the dry bush is blown around the prairie like a tumbleweed, scattering seed as it goes.



The strangely named Goat's Beard (Tragopogon dubius) is eaten by grazers and the mature seed-head resembles a giant dandelion showing a large white ball of plumed seeds.   The edible roots of Goat's Beard are reported to taste like parsnip or oysters (do those taste alike?) and the plant contains a milky latex sap that was chewed as gum by our prairie ancestors. 

 
 
 
 
 

 

Moth Mullein (Verbascum blattaria) is another oddly named prairie forb that comes in both white and yellow flowers.  We consider it a Kansas native, although the species is actually native to Eurasia.  The individual blooms are a natural artwork of color and form when examined closely.

 

 

 

 

 

 

 

 

 

 

 

I think I've identified most of these forbs correctly so far in the last two posts, but I lose some confidence on the myriad of small yellow composite-form flowers that inhabit the prairie.  One of those blooming right now is (I think) properly named Prairie Groundself (Packera plattensis).  If I've got the name of this one wrong, I'm sorry.   This one can be poisonous to cattle, but is rarely consumed in enough quantity to cause a clinical problem.

 

 

 

 

   

And somewhere out there amongst the prairie grass, the Killdeer eggs are still incubating in the Kansas sun:

 

Leafsnap!

We interrupt this special series of local Kansas wildfauna to bring you a special announcement.

The local Manhattan Mercury ran/copied an Associated Press article tonight about a new Ipad/Iphone app called "Leafsnap." Using this app on your Iphone or Ipad, you can snap a picture of the leaf from any tree, preferably against a white background, and it searches a growing library of leaf images created by the Smithsonian Institution and returns a likely species name and information on the tree's flowers, fruit, seeds, and bark.

River Birch

I had only a few minutes before darkness tonight, but downloaded the app and it correctly identified a redbud and a river birch.

Did I mention it also collects the GPS where you snapped the picture and creates a "collection" for each user? That the eventual idea is that the app will be used by people everywhere to map trees in their area? That in the future the plan is for anyone to be able to locate a unique tree species in their local area?  At present, the app is just set up for New York, Washington D.C., and the northeast, but it allowed me to create an identity and correctly labeled my location in Kansas.  I am now ProfessorRoush on Leafsnap.

Imagine the same tool for insects, wildflowers, roses, fish....

Imagine the possibilities.....

Find the app on your local Apple appstore, or see it at http://www.leafsnap.com./  It's free.  And I guarantee it will bring back the Cub Scout, Brownie, 4-Her, or freshman biology student in anyone!



(PS:  I wrote this entire blog on my Ipad for the first time.  Except for the picture, which I could not get to upload to blogger from the Ipad either directly or through Photobucket.  I'll work on it.)
