The ditches come back in March.
When water goes into the Atrisco Acequia Madre and the Arenal, Armijo, Los Padillas and Pajarito laterals, the year restarts across 30.3 square miles of unincorporated Bernalillo County just south and west of Albuquerque. It runs down long, narrow lots laid perpendicular to the ditches — farm geometry inherited from the 1692 Atrisco Land Grant and still readable in the parcel lines off Isleta Boulevard, the old Camino Real. It soaks into ground sitting at 4,928 feet, the lowest in the metro, where the Anapra, Agua and Glendale soils already carry a water table 45 to 60 inches down. Every large tree out here drinks on that calendar and roots shallow because of it.
So do the families. Of 13,186 occupied homes, 74.4% are owned by the people living in them; the median house went up in 1970 and 65.9% of all units predate 1980, with 18.4% older than 1950. On plenty of these lots the original house stands up front and a second dwelling sits beside it — often one of the 2,127 manufactured homes that make up 15.1% of the stock, set down in the shade of trees somebody's grandparents planted. Roque Tree Service works the valley the way the year runs here.
Spring: wind on the ditch-bank elms
Late March and April bring the gusts and the blowing sand. On March 6-7, 2025, 65 mph gusts put trees down across the metro. What they find first is Siberian elm, which lines every ditch, fenceline and back alley in the five-acequia network: 70-plus feet tall, rooted only one to three feet deep, with branches that routinely snap off and fall from significant heights. It also seeds in the billions from March through May, which is why an unmown strip along a ditch bank becomes a thicket in one season.
Whose elm it is depends on the line. Overhang across your fence is yours to trim, and we cut it back at the property line. A trunk inside MRGCD's right-of-way is the district's, through a removal request that runs three to six months. New Mexico's acequia easement statute gives the ditch a right of access with machinery, so on the tight Atrisco and Armijo lots we stage the boom truck and chipper in the yard, never on the ditch road. Spring, before leaf-out, is also the cleanest window for structural pruning and for taking out a hazard tree ahead of monsoon season.
Summer: monsoon over the manufactured homes
From July into early September the valley gets microbursts; a July 2026 severe-thunderstorm warning for Bernalillo County cited 60 mph gusts, with a 58 mph gust recorded at the Sunport. A manufactured home under inherited canopy is the most exposed structure out here — low roof, short setback, a driveway too narrow for a bucket truck to swing, and a full-size cottonwood or elm limb directly overhead. A branch that would dent a stick-built roof goes through this one.
That makes clearance pruning the summer job: deadwood out, the limbs over the roof and the service drop shortened back to sound side branches, weight taken off the long horizontal leads. Elm leaf beetle defoliation peaks in the same weeks and browns whole crowns, which is a stress signal rather than a death sentence. PNM prunes near its distribution lines on a planned schedule and tries to reach the owner first — but after a storm the utility leaves the debris, and clearing it falls to the property owner. We haul it. Emergency service runs 24/7, and we head out within about an hour, depending on distance.
Fall: mulberries, topping and the county line
Irrigation ends, the ditch banks dry and firm up for equipment, and leaf drop exposes the deadwood and the hollow unions a full crown hides all summer. It is also the season people ask about the old mulberries in Atrisco and Armijo, cut back hard every few years the way they always have been.
Here is the honest version. Topping leaves stubs that decay from the cut face inward and answers with weak sprouts, so the tree needs cutting again sooner and holds together worse each round. Crown reduction to a live side branch usually keeps the shade and the structure both. We will still top a tree on request once that is in writing. And one city rule stops at the line: Albuquerque's 1994 pollen ordinance bans new mulberry and cypress inside city limits, and the South Valley is unincorporated county, so a mulberry here can be replaced in kind. Fruit trees on the acequia lots — apple, apricot, peach, plum — get pruned after leaf drop.
Winter: cottonwoods, clearing and the second house on the lot
Most of the giant Rio Grande cottonwoods on these farm lots come from the 1941 flood cohort and are reaching the end of an 80-to-100-year life. In September 2025, after a light snowpack and an intermittently dry river, KUNM reported yellowing crowns and more than the usual amount of fallen branches. A tree in that condition standing within a limb's length of a 1950s ranch house is the valley's recurring big job: deadwood, reduce, and eventually take it down. Zone 7b winters are the time to do it, when the tree is dormant and frozen ground carries equipment across soft clay that would rut in June.
Winter is also clearing season. Russian olive, salt cedar, tree-of-heaven and elm seedlings colonize any idle irrigated parcel, and the 2003 Atrisco Complex fire in the bosque north of I-40 is the reminder of what that fuel does. Lot and brush clearing opens ground for a second dwelling, brings a pasture back, or puts a gap between a thicket and the buildings. Before stump grinding we contact 811 and locate the septic field and any shallow well — on old valley lots those are rarely where you would guess.
The five villages, and Mountain View
- Atrisco — the 1692 land-grant village and the valley's oldest settlement, urbanized in the 1950s–70s where Bridge meets Central and Old Coors; small lots under a heavy elm and mulberry canopy.
- Armijo — acequia village along Isleta Boulevard south of Bridge; old adobes and 1950s–60s houses on long lots that still back onto the Armijo ditch.
- Arenal — semi-urban, semi-rural ground around the Arenal Acequia and Sanchez Farm Open Space, irrigated pasture beside newer subdivisions.
- Pajarito — rancho settlement near the Gutierrez-Hubbell House, with larger irrigated lots, horse properties, old cottonwoods and a notable share of manufactured homes.
- Los Padillas — the southernmost village toward Isleta Pueblo: open rural ranchos, acre-plus lots, cottonwood windbreaks over acequia-fed fields.
- Mountain View — east of the river along 2nd Street SW between the Sunport and Valle de Oro, residential pockets among industrial neighbors.
What needs doing now, and what can wait
Median household income here is $58,224 against $71,494 for Albuquerque city, and three of every four homes are owner-occupied — meaning the person paying for the tree is the person who owns it and has probably owned it a long time. So we separate the estimate into what is a hazard now and what is fine for another few seasons, and say which is which out loud. The estimate is free and in writing, tree by tree, and there is nothing in it you did not ask about.
Getting here is quick: about seven road miles and fifteen minutes from Southeast Albuquerque to the Bridge and Isleta core, roughly twenty-five minutes down to Los Padillas by I-25 and Rio Bravo Boulevard — the nearest community we serve.
