I need to confirm with my next-door neighbor and his rain gauge, just how wet it’s been in 2017 and in these recent storms. My guess is 2017 to date is at least 10 inches of rain, which is over 2 inches or 25% above average – but for the entire year. We have 2 months left.
Below, the same tan grass now was a green carpet over most every hill here.
Six Weeks Grama / Bouteloua barbata is a common, native annual grass in the southwest.
We had another 1 inch or even more in a late night downpour, with more lightning than I’ve seen in a couple years. But no matter how much falls, Six Weeks Grama will not re-germinate – the temperatures are cooling into fall levels, and that grass only seems to germinate in late summer and no other time.
As long as native grasses don’t grow too rangy or leggy in key areas, I assume keep them for aesthetics and function.
Even as an annual, this grama does a good job holding in the loose soils here with their roots, while gravel mulch can only cover the soil and soften the blows of wind and hard rain. Gravel cannot root.
My fingers are crossed for restraint in such areas.
The tan really creates a good visual contrast to the greens of Yucca faxoniana and Larrea tridentata.
