Weekly update: Drought is one of those events that frays the social contract. When available resources fall below critical levels for survival, individuals no longer accept the consequences of sharing. Perceptions of individual worth become exaggerated.
Apple trees suffer one of man’s most ingenious forms of cooperation. When trees are grafted, vigorous specimen’s are beheaded, and given tops from other trees which produce better fruit. To work, the graft joint must allow water and its minerals to flow up to the scion, and the products of its photosynthesis to return to the roots.
When times are bad, the biochemical signals apparently don’t work. Last summer, when the heat came and the rains did not, my ungrafted raspberry roots sent messages upward, and fruit production stopped. The half-formed berries shriveled, but the roots are back this year.
I’m not sure how those drought survival messages work when they travel between two individuals. Last summer’s trees continued to produce larger than usual crops with decreased water.
The tops were determined to reproduce seeds after the previous year’s frost had destroyed the buds.
This year suckers are appearing at the bases of trees, as roots are determined to ensure they receive the full benefits of photosynthesis they need.
Most of the local trees are classed as semi-dwarfs, and probably are grafted onto Doucin Reinette. This particular variety has been used since the late 1600's because it survives cold winters and wet soils. Unfortunately, it "suckers profusely," even in good years.
My trees never got the water they needed. My water pressure didn’t deliver in the night, but I didn’t realize the problem because I always saw leaves from a distance. When I began to wonder why I never saw flowers, I discovered the roots had replaced the desired tops on half, and threatened the other ones.
Men who are smarter about their trees don’t let this happen. They inspect their trees in winter when they prune. But this year, even they have suckers appearing. The resources of most are limited to the water provided by the ditch association, which in turn is constricted by the fact it is only one of several acequias using the Santa Cruz dam. The state doesn’t approve using groundwater for irrigation when it issues well permits. The city has its own methods, including rates to limit the flow of a critical resource in what is the third consecutive dry summer.

Weather: Last rain 4/09/13; 14:31 hours of daylight today.
The weather forecast for the past few days for Los Alamos and Santa Fé included a chance for thundershowers. What that meant was dry monsoons. Clouds appeared in the afternoon, along with winds. Temperatures dropped instead of increased. A few sprinkles fell, if anything that lasted less than a minute could be called that.
I took advantage of those predicted cooler afternoons to put out bedding plants and new perennials. Seeds can come later, but I put some in, if they happened to go in the area where I was planting. They have to deal with the winds, but if I wait until the winds die down, I suspect summer temperatures will come and nothing can be transplanted safely. A week ago I was still dodging frosts.
What’s blooming in the area: Austrian copper and yellow roses, iris, first oriental poppy.
While some have decent lilacs, most aren’t blooming. Since they like cold weather, I assume either the warm afternoons or the high winds arrested their development.
Beyond the walls and fences: Apache plume, tamarix, alfilerillo, hoary cress, tumble mustard, western stickseed, tawny and bractless cryptanthas, purple mat flower, blue gilia, fern-leaved globemallow, greenleaf five-eyes, tufted white evening primrose, scurf pea, common dandelion, June and cheat grasses. Buds on bush pea.
Last year I dug up a something that looked like a wild onion to see if it had a bulb. Brought it home and stuck in the ground. Found it blooming Tuesday.
In my yard: Siberian pea tree, spirea, grape hyacinth, Baby Blue iris, Dutch clover, oxalis, blue flax, vinca, small-leaf soapwort, snow-in-summer. Buds on snowball, beauty bush, Bath pinks, golden spur columbine.
Bedding plants: Marigolds, nicotiana.
Known unknowns: Pink bud, native dandelion, fleabane.
What’s blooming inside: Zonal geraniums, petunias.
Animal sightings: Rabbit, small brown birds, geckos, harvester and smaller ants. Hearing hummingbirds fly by.
Weekly update: When people talk about a loss of biodiversity from the increase of greenhouse gases, they forget nature adapts. For everything lost, something new is created.
Apache plumes are native to the southwest. Colorado State University Master Gardeners tell you the semi-evergreen shrubs aren’t "particular about soil types." While they are thinking of your well-conditioned garden dirt, they add Fallugia paradoxa "will perform best in sandy soil or clay loam."
In this area, they don’t grow on the Miocene-based prairies, but on Pleistocene canyon fill. They can be found on the western flood plains of the far arroyo and along the tops of the first tier of banks, where the land is built from layers of sandy loam and pebbles. Yesterday, the ones in the arroyo had leaves that were still bright, but beginning to darken.
The ones on the shrub on the bank downhill from the road cut hadn’t shed last year’s brown yet.
The ones growing on a cultivated, purchased shrub in my yard were dark green.
The difference is water. The shrub on the bank may have been part of a copse that was divided when the road was cut. There’s a plant on the opposite bank that’s a bit greener, because it’s on the wetter, upland side of the road.
The downhill shrub is retreating from the eroding bank. Each year, it puts out new plants, and more of the existing plant dies. The corpses line the bank. I don’t know if the young are suckers or seedlings, but I know I don’t see them around Apache plumes in the arroyo. You will, however, find a copse developing around a shrub on the opposite bank of the arroyo on the downhill side of the road cut.
A different type of migration is practiced by plants whose seeds can spread farther. Yesterday, as I continued walking along the rim of the lower bank, I noticed the only tawny cryptanthas blooming were some that had settled in the gravels of a gully from the bank down to the arroyo. Their normal hill side is dry and barren.
In the next gully, I found blue gilia blooming with them. The normally bloom on the bank opposite the cryptanthas in another gully leading to the arroyo.
In the third gully I found some fleabane. This peripatetic flower usually appears in people’s irrigated fields. Here only the flowering stems were green. The rest had browned.
They were all that was blooming on the prairie, and all had come up in gravelly land that holds more water than sandy loam. When I moved inland toward their usual home, I found some sweet sand verbenas. They normally grow on a rise, but this year nothing is there but dead grass. These came up in the path downhill where there was a bit more water in winter. But with the dry spring, they’d abandoned blooming and were turning brown.
If you lived on one of the hills where these plants normally bloom, your spring would have been one of drought-induced depravation like those feared by people concerned with climate change. If you happen to reside in one of the gravel wastelands, this bad year has been the floristic boon expected by the deniers.

Weather: High winds and very warm afternoons; last rain 4/09/13; 13:47 hours of daylight today.
We’ve had the apricot frost, the apple frost, and this week the one that threatened the grapes, catalpas, black locusts, and roses of Sharon.
What’s blooming in the area: Austrian copper rose, lilacs, iris. Catalpas, grapes leafing.

Animal sightings: Rabbit, small brown birds, gecko, ladybugs on peach, gray butterfly on Dutch clover, harvester and smaller ants.
Keep seeing or scaring up grasshoppers. Not a lot, but they are around.
Weekly update: People say time stands still in New Mexico. Where I live, the surface rocks were laid down during the Miocene, 12 to 15 million years ago, from pieces eroding from the Sangre de Cristo near Picuris. Grasses were evolving, and still dominate.
Of course, some things happened since then. The rift valley already had formed, but the Rio Grande didn’t become a flowing river until 3 or 4 million years ago. The Jémez caldera formed a million years ago. Man arrived.
Clovis is now estimated to have existed 13,500 to 13,000 years ago. Ranchers staked land in the late nineteenth century. I don’t know when they built the road that goes by my house, but someone maintains it, probably with a blade.
The land slopes toward the river. It drops eight feet from the top of the eastern hill to the road. The road is a flattened area that disrupts the flow of water to the down hill side. Just beyond where the road passes my house, the blade pushed dirt to the sides, creating berms that amplified its impact.
The land up hill is undisturbed. The land toward the river is steppe land dominated by winterfat.
I don’t know what dictated the location of the road, if it marked property lines or followed some natural contour it destroyed by its levelness. The land downhill has a gentler slope than the land to the east. The western side of the road is also flatter, while the uphill side has a shallow valley that separates a ridge-like hill from the main slope.
Directly across from the valley a line of cholla cactus grow. Like the grasses, they haven’t recovered from the dry summer of 2011.
The vegetation changes at that line of cholla. There’s little winterfat. If the ground is wet, four-winged salt bushes grow. If the land is dry, there may be a prickly pear.
It’s easy to blame the road. With the ridge, the road begins to cut though the slope on the uphill side, diverting water down the road, rather than across. But, it isn’t simply a matter of different water patterns. Cactus also can be found uphill.
The land is changing. A bit farther down the road, the land drops severely, and the soils are younger, laid down since the retreat of the glaciers.
Drive anywhere in this part of the state, and one of these plants is visible. Cholla grow on the east side of the road on the flat land before La Bajada Hill outside Santa Fé and on the east side going north of Española through San Juan land.
Prickly pear is harder to see because it lies low. Much of the winterfat probably was destroyed by grazing animals. The water loving chamisa, found here in the arroyo, and salt bushes that hug the water courses are found along the shoulders on the road south to Albuquerque where water collects from the pavement.
The vegetation says there’s more to the soil than sandy loam, for these common plants aren’t as promiscuous as they seem.

Weather: High winds early in the week, temperatures below freezing Wednesday; last rain 4/09/13; 13:38 hours of daylight today.
What’s blooming in the area: Few apples or crab apples, first lilacs, tulips.
Beyond the walls and fences: Alfilerillo, hoary cress, western stickseed, tawny and bractless cryptanthas, purple mat flower, common and native dandelions. Virginia creeper leafing. Siberian elm seedlings coming up everywhere.
In my yard: Siberian pea tree, grape hyacinth, vinca, oxalis. Spirea in bud.
Known unknowns: Pink bud.
What’s blooming inside: Zonal geraniums, petunia, aptenia.
Animal sightings: Small brown birds, gecko, bees, ladybugs on peach, harvester and smaller ants. Probably aphids somewhere if there are ladybugs.
Weekly update: They call the soil hereabouts sandy loam. When you ask what that means, you get that look older brothers reserve for younger when things are too obvious to explain, and too complicated.
It’s some mix of sand, silt and clay. Most likely equal parts. Maybe created during the glacial age. Sand is the ground remains of quartz. Clay the remains of rocks weathered by carbonic acid, that is carbon dioxide in water in the cold. Silt is ground feldspar and quartz that’s midway between clay and sand in size, and easily blown by the wind.
All created by the breakdown of mountains, all some kind of silicate, which I only recognize as quartz. The clay is the part that holds water, sand the part that drains.
When I walked out to the far arroyo last Sunday, a week or so after the last very high winds and before Tuesday’s, my first view was sand everywhere, collecting, burying whatever obstructed its path. When I stuck down a stick, it went 1.5" before hitting something solid. The footprints were not lying.
I suspect the drying airs have pulled so much water from the soil, the clays have taken flight, and possibly the silts. The surface is littered with tiny pieces of quartz that gleam in the light. What’s heavy is what remains.
It’s nothing new. Every dry year segregates the soils a bit. Every wet year deposits organic matter and activates the soil creating crust bacteria. More dry years than wet, and arroyos turn to sand. More wet years than, dry, the land is rebuilt.
The plants that can find water are doing well. The chamisa in the bottom is leafing at a faster rate that the bright green stems on the banks.
Its low branches trap its dead leaves which shield the moisture from the sun. It’s roots reach down far enough to reach the still good soils and water. It roots in wet seasons, like last spring, and survives the dry.
Others are struggling. The tawny cryptantha is blooming in places in the arroyo near banks where water drips or washes, where shadows hold it and wind currents are deflected. It is not blooming in its usual places on the prairie yet.
The gypsum phacelia is up near the Russian olive, but the plants are still short. There are few this year under the tree. The ones ready to bolt are growing near chamisa.
The pink buds are coming into bloom. They only grow on the upstream sides of two chamisa. I don’t know if that’s because the south sides get more water or more heat. After all, I still don’t know what they are, just where to find them.

Weekly update: A year ago, the sand verbena were getting ready to bloom. By July, the heat and drought had returned. The grasses hadn’t revived. There was no way I would have known this area had so recently bloomed.
A month ago I was walking along the side of the verbena hill, when I thought there was more gravel on the path than I remembered.
That was the first time I realized the wind was as important as the frost in exposing what lay beneath the surface.
Intellectually, I knew the ground where I was walking was a layer cake that alternated tiers of sand with ones of pebbles washed down from the Peñasco embayment. I could see the strata in the arroyo a few feet away.
I also knew from Wikipedia the taproots of Abronia fragrans could reach down anywhere from 7" to 3'. The surrounding grasses tend to concentrate their root mass in the top 6" of soil. Although needle grass roots may reach deeper, the ones in my yard are shallow.
I simply never connected the details. Someone, I kept my midwestern image that vegetation was a thatch more dependent on the topsoil than on what lay beneath.
It did not occur to me that maybe the reason that area was more fertile than the one ten feet away was that it had more gravel at the right level to retain water for the roots of the verbena, and, perhaps not enough to support the grasses in arid times.
