| "Prestige" buffalo grass in January 2013, approximately 5-months after planting in 2012. I scattered some mulch around the plugs closest to the camera to try to keep down weeds. The majority of the plugs, especially those furthest from the camera, just have bare ground between them. |
So last August, as some of y'all may remember, I took the plunge and planted some buffalo grass.
I had three primary reasons for wanting to cultivate a buffalo grass patch:
1) Buffalo grass is supposed to be very tough and able to tolerate heat and drought. This is important because summers can be very hot (90-100+ Fahrenheit) in Tennessee for months at a time -- sometimes without any rain for weeks. I'd like to cut down on my supplemental irrigation, so finding plants that can survive a drought is key.
2) Buffalo grass is supposed to be low-growing. Especially the varieties that are sold for lawn use - like the Prestige variety I bought - are only supposed to get 4-6 inches tall over an entire season. That means you could theoretically not mow your lawn at all, or maybe just once or twice per year.
3) Buffalo grass is native to North America (although I think it is more native to Western parts of the continent).
4) Buffalo grass requires far less nitrogen fertilizer (1-2 lbs per 1000 square feet) versus conventional lawns (e.g. Bluegrass at 3-5 lbs per 1000 square feet). I'm always looking for ways to reduce external inputs such as fertilizer for more eco-friendly (and wallet-friendly) landscaping.
So, how did the buffalo grass planting turn out? I posted a 2nd day update, but this is my first time revisiting the buffalo grass patch since then on this blog.
To be honest, it's not particularly a pretty sight at the moment. As I'd expected, the buffalo grass went into hibernation mode ('dormancy' is the technical term, I believe) once nighttime temperatures started dipping below freezing in late October and early November.

| One advantage of the buffalo grass plugs not growing together yet is that there was space for some self-sown lettuce seedlings to emerge. I believe this is Merveille de Quatre Saisons. The lettuce never got all that big, but I did pick and eat the baby lettuce one night when temperatures were forecast to drop into the teens, which I thought might damage the tender lettuce leaves. |
The winter color is not unattractive - I like to think of it as 'tan' or 'golden'. I less charitable soul would probably call it 'brown'. Beauty continues to be in the eye of the beholder.
The main lesson I think I can pass on from my experiences thus far would be this: If you live in a climate where temperatures drop below freezing in winter, it doesn't really make sense to plant buffalo grass in late summer.
Because while I think all the plugs survived being transplanted into an August heatwave, I also think it took them a while to settle in and get rooted. Plus they required frequent watering around the transplant time.
It probably would have been smarter to plant the plugs around May. In a good year, we're still getting nice spring rains in May, so the buffalo grass plugs probably wouldn't need much supplemental irrigation. And then they would have all summer to knit together by growing into each other along stolons.

It's hard to tell from the picture, but some of the plugs did start to send out runners and interlace with one another, but they didn't have a chance to complete that process before the weather got cold and the new growth shut down for the winter.
And because they had not yet knit together, that left plenty of space for weeds to develop. (I picked most of those weeds out by hand, which wasn't too hard in most cases, although I had to be careful not to damage buffalo grass roots.
On the bright side, the stories about buffalo grass being a low-growing grass definitely seem to be true. When the grass did start growing, it focused its energies on lateral growth rather than vertical growth. So I can definitely see this being a grass that needs hardly any mowing to keep it at a reasonable height for a lawn.
So that's the story right now.

My hope is the buffalo grass will start greening up in late March or early April, once the temperatures start staying above freezing at night and daytime temps are reliably in the 60s or higher. (It's actually around 70 Fahrenheit today, but that's not going to last. We'll be going back to highs in the 30s-40s range and lows in the 20s by the end of the week.
Presuming the grass is still alive and in good shape, I will post another update when it starts greening and then hopefully be able to post additional updates in the summer if it does start forming a solid patch of grass.
Based on my experience thus far, I don't feel I know enough yet to say whether or not buffalo grass would make a good alternative to other lawngrasses in the Southeast. I can say that if I were to do it over again, I would try to get an earlier start planting the buffalo grass (by June at the latest) to give them a whole summer to try to grow together and form a solid patch of turf.
