Snow Day

The rare beauty of a cloaking of snow on the Tucson Mountains
With predictions of wind and rain and snow (really?) last night, we went to bed wondering what the morning would bring.  The howling wind and lashing precipitation in the middle of the night coupled with the pacing of our nervous dog made for less than sound sleep until the wind abated before dawn.  Finally things quieted down and I awoke well after dawn to find our nearby Tucson Mountains heavily powdered with snow, a serious rarity around here.

Before noon most of the snow was gone, but the frenzied activity of the birds gave credence to the freeze predicted for tonight.

After the catastrophic freeze a few weeks ago, three nights with temps in the high teens and low 20's, we figure what was going to suffer from serious cold will have already done it and will likely not bother to cover much tonight.  What doesn't survive we'll do without (simplify, simplify, simplify), or replace with plants that can survive temperatures in the mid-teens.

At least we had good weather for a wonderful and long-overdue visit with my daughter and son-in-law recently.  Tucson is like a third home to them, the San Francisco area being their first, so they were not interested in playing tourist every day, though we still got some of that in.  The Desert Museum is always a must, especially when your hosts volunteer there -- one as a docent and the other volunteer with the botany department.  Then we also managed The Cup Cafe at Hotel Congress for breakfast, Tohono Chul Botanic Gardens and lunch at the Tea Room there, and lot and lots of walking the hills of the Tucson Mountains, be they snow covered or not.

The early afternoon sleeting has just stopped and once we get past tonight it looks to be highs in the 70s and 80s.  Bring it!

The Big Chill

When the weather cools to that perfect high of around 70, we start seeing hot air balloons more frequently, early in the mornings when the atmosphere is cool enough for their warmed balloon interiors to make a difference and provide the essential lift.

Chilly morning hot air ride
Tucson gets about 20 nights of freezing temperatures a year, usually a glancing blow of a few hours just below 32 degrees.  The first one usually occurs right around Thanksgiving, so we were right on schedule.  Problem was, it was predicted to be a hard freeze -- 24 degrees.  It was time to deter the Big Chill.

Out came the styrofoam cups, insulating caps for columnar cacti.  Out came the paper bags, ditto.  Out came the plastic picnic tablecloths with the fuzzy underside (important), old beach towels and coverlets.
We even used a few baseball caps for our larger cactus "heads".




One of my very favorite plants in our backyard is the chuparosa.  It begins flowering in November and flowers all winter long, its tubular orange flowers providing nectar for our year-round Anna's and Costa's hummingbirds along with the nectar robbing mustard headed perpetual motion verdins.  We have a few of these magic winter plants, but my favorite is right outside the dining room window and is the size of a Volkswagen beetle.  I was determined to save this plant from freezing -- it wouldn't kill it but would literally nip it in the bud, likely nixing any more flowers for almost a year.  Several years ago we had a freeze in the high teens and the chuparosa looked like it had been freeze-dried.  We cut it back to medicine ball size in the spring and it bounced back, but I wanted a natural food source for our hummers.

I took every large plastic tablecloth I had, plus some old towels and a bedspread, draped them over the chuparosa and clothes-pinned them together.  We put a trouble light under the cover and kept it lit all night.  It looked like The Blob was having an eerie picnic in the back yard.  Out of appropriate covering, the two rows of green beans we'd been nursing along in our feeble winter vegetable garden would have to fend for themselves.

By night
By day
We saw hummingbirds zipping under the cover at first light, the sugar water in their feeders frozen solid. As I uncovered the chuparosa today, a Costa's hummingbird flashed his royal purple gorget at me, whether in thanks for saving his favorite winter plant or to urge me to get out of the way, I'll never know.

Success!  At least for Round One...
The hummers' food survived.  The green beans -- not so much -- but I can get great ones, cheap, at Costco.  Our flashy hummingbird winter companions?  Priceless.

If You are Thinking This is a Bird Deterrent...

...you'd be wrong.


Not more than a few hours after carefully sowing our seeds in nice straight rows, plant stakes in place with names and planting date, we went out to finish the watering job Mother Nature had started.  Our lovely garden, well mulched with an even coat of alfalfa hay, had big gouged out areas, hay tossed aside, spots in the amended soil -- amended with steer manure -- showing dark and moist.


As this area is inside our block walls, the culprit couldn't be a rogue javelina, mule deer, or bobcat.  No birds around are big enough, or interested enough, to so seriously mar the new garden.  No children here to run amuck.  


The real culprit



The string and tin foil solution?  So far so good.

Winter Garden

We're not novice gardeners.  For many years we've learned, mostly through trial and error, about what will work in our desert garden and what won't.  We've become increasingly committed to native or desert adapted plants -- plants that work well here and are of use to the local birds and other critters.

A ghostly aloe in the barrio garden
It seems a bit odd to be putting in a winter garden when we were in triple digit heat a few days ago.  Now there's nothing but highs in the 90's in the forecast, and the nights are promised to be blissfully in the lower 60's, so hopefully we've turned a corner.  Still, while our family in Denver are harvesting the last of their crops, we are just beginning.

We always said that if anyplace could drag us permanently away from Tucson it would have to be somewhere that we could do edible gardening in terrific soil with rain that fell from the sky on a regular basis.  But we both love living in the Sonoran desert, especially now that we have a real cabin in the Colorado Rockies to escape to in the summers, so we're not moving.  Ever.  Recently my husband went to a winter gardening class at Plants for the Southwest, one of our favorite nurseries here.  The class was taught by a woman who's been veggie gardening here year 'round for over two decades.  Soil amendments (organic) and knowing what to plant when were the keys.

Pew
Do you know how stinky big bags of steer manure are in the back of an SUV on a hot day?!  Luckily that trip was followed by a trek to get a bale of alfalfa hay which has a lovely grassy smell and left enough of itself behind in the car to freshen up the Honda C-RV.  A dozen packets of seeds, some additional drip irrigation sprinklers, and a "flat free" puncture-less foam filled wheelbarrow wheel and tire to replace the far from "flat free" inner-tube (thorny deserts are hard on them) pretty much completed the necessities for planting our winter garden.

Double digging in the last of the shade
We chose a sunny wall to plant the garden against.  After moving a couple of plumbagos, a Mt. Lemmon daisy, and a salvia, Bob began the double digging process to incorporate these new organics.  This is not an untouched area; we have amended this before.  Deserts are not know for their rich humusy soils, and our yard is no exception.  Developing our vegetable garden's soil will be an ongoing project.

Deep digging and existing drip irrigation systems always clash, but after a lot of digging, a few repairs and additions to the drip system, some raking, with a well-deserved brunch mixed in, we were ready to plant.

Big brunch for hard workers

Ready for seed sowing
By the time we were ready to sow some seeds it near noon and in the high 90's, but we were determined.  In less than an hour we had rows of two kinds of snap beans, snap peas, sweet peas (the flowers), quinoa (our experiment), spinach, two kinds of kale, swiss chard, and garlic.  When it cools off a bit more we'll plant some lettuce mixes and radishes.  Herbs are growing in containers.  Onions will go in after Thanksgiving.  Bob spread a nice layer of sweet smelling alfalfa hay over the bed as a mulch to retain moisture and shade the seedlings.  Eventually it will be dug into the soil for enrichment for next years winter garden.

Just went out to check it...nothing yet.  I guess five hours is a little too soon for germination.

Hatch Watch

When we got back from Colorado 20 days ago we spotted a female Gambel's quail roosting in one of our flower pots out back.  We don't know when she finished laying her clutch of 10 eggs, but we do know that incubation is between 21 and 24 days, so we can't be too far away from a hatching.

Last night we noticed a male Gambel's quail lurking around the nest.  Suddenly he squatted down on a bare expanse of gravel.  Had he been on dirt we'd have been expecting to see him take a dust bath, but he hugged the stoney ground, looking over toward where the female sat on her eggs under a potted flowering euphorbia.  These quails are monogamous and both take an active role in raising the chicks, but we had to wonder if this was maternity ward waiting room behavior.

It didn't take long to get our answer.  After a couple of minutes the male rose and cautiously approached the pot with the nest and tentatively joined his mate, carefully settling on some of the eggs.  After doing some research we learned that the male incubating the eggs is not unheard of, but quite rare.

You can see the female in the above picture, her shiny eye just above the edge of the pot.  The male is behind her, his black and chestnut head facing the other direction.

I guess we're the ones waiting anxiously in that maternity ward waiting room.

Sanctuary and Answered Prayers

Shortly after the official start of summer the Sonoran desert is well into its infamous heat, but the notorious dry heat is giving way to a steamier version.   When the weather pattern shifts, usually around the 4th of July, our desiccatingly low to nonexistent humidity gives way to an inflow of tropical moisture, bringing the novelty of clouds, and we wait anxiously for the first rain in months.

We like to help out our tough desert birds by providing fresh water, native food sources though habitat gardening (and the occasional handful of bird seed), shelter, and places to raise their young.  Our efforts are rewarded by the constant presence of some of the most fascinating and adaptive birds in the world.  In the middle of our hottest season we are seeing lots of fledgling birds -- slightly smaller than their parents, frequently seen harassing  them with begging behavior, and not quite as expert in the flying department.  We've had juvenile doves, cactus wrens, thrashers, gila woodpeckers, finches, and even a young pyrrhuloxia seeking the shade of the back porch.


While desert birds have strategies to deal with the long months without rain in a land of little standing ground water, an easy source of water for drinking and bathing is much appreciated.  This early clutch of Gambel quail are being shown the ropes by their parents, visiting the bird bath for a quick early morning drink.

While some quail families are just finishing up their parental duties with their fledglings, others are just beginning, or beginning again.  This clutch of ten eggs is usually hidden by a dedicated female quail, and is due to hatch any time now.  Seeing a string of puffball quail chicks obediently following their mother while papa quail stands guard duty on the garden wall is one of our favorite desert experiences.  A year with abundant (for us) rainfall insures the resources needed to raise more than one family a year, and we are witnessing a banner year for wildlife.

Late this afternoon, bolstered by adequate humidity and triple digit heat, we had our first brief rain of the monsoon.  There is nothing like the first rain after months without, months of searing heat.  The first drops steam off the hot flagstone, and the fragrance of creosote instantly fills the air.  The cool rain on hot parched skin is an exquisite study in contrasts.  And the breaking of the long absence of life-sustaining rain is an answered prayer.

Heat and Prayers


We're back from a month in the Colorado Rockies.  The triple digit heat is a bit of a shock.

When we left in late May it was certainly warming up.  The paloverdes had finally bloomed, making the desert feel as if pale sulfurous yellow clouds had descended to within a few feet of the ground.  The stately saguaros were starting to bloom, satisfying the white winged doves who'd arrived a few weeks before to fulfill one of their purposes in life of moving saguaro pollen from one cupped flower to the next.  The first strings of puff-ball baby quail were being squired through the backyard by their proud and watchful parents.

Our blessedly cool and rainy winter and early spring created a window of opportunity for plentiful reproduction.  Over a month ago we saw our first fledgelings, almost as big as their parents who they chased down and begged for food by trembling their able wings accompanied by nagging cheeps.  Yesterday I was treated to a display of dove love, a mating session in the mesquite outside my kitchen window.  As soon as the brief tryst was over one of the fledglings from the first clutch flew in to join mom, just in case she had something to feed him.  

We are habitat gardeners, but I'll admit to trying to dissuade the doves from nesting in other than natural spots -- in other words, I'd far prefer they use a tree or cactus than my back porch beam or the porch light.  Since the doves build their nests, a loose pile of twigs, in about seven minutes flat, you have to catch them at it.  Well, we got doved.  Yesterday when I walked out the front door to get the mail something near my head exploded.  It was a panicked momma dove vacating her nest, the one she'd built on our porch light.  I got a step-stool to check for eggs and sure enough, there were two, so mama dove gets to stay.  I'll admit it's a sweet spot for her -- shaded and safe from predators other than the winged variety.   We'll hope for a minimum of dove drama -- no naked babies falling from the nest please -- and hope for two healthy chicks that fledge successfully.

In late June we're heading for 110 degrees.  The saguaro are almost done with their blossoms though you see a stray one here or there, and heavily into fruiting.  Green fruits the size of small pears split open, revealing their juicy crimson interiors riddled with tiny black seeds, over 2,000 of them per fruit.  At a time of the year when rain has been non-existent for months, the sweet wet fruit is irresistible to anything that can get to it.  Birds have the easiest time of this while the fruit is on the cacti, but once it falls to the ground it's appreciated by most desert critters.  Birds and other animals, having eaten the fruit, move on and eventually -- through the process of elimination -- disseminate the seeds where one or two, out of millions produced by a saguaro over its long lifetime (which can be well over 200 years), might survive to maturity. 

It's a harsh environment, and one is reminded of that constantly watching the strings of baby quail get shorter by the day.  Near the summer solstice the light is white over the parched landscape.  Plants employ all their strategies -- dropping leaves, dropping whole branches, shriveling to the point of looking as if they'd been in a wildfire -- to survive until the monsoons arrive.  These summer rains the Sonoran desert is so dependent on are born from our searing heat and tropical moisture.  We've had a little pulse of the moisture in the last couple of days, and heat we have in abundance, but not enough moisture to humidify our scorched atmosphere enough to have something left over to wring out.  This is where the praying kicks in -- praying to Mother Nature to give us what we need so badly, the healing release of a hard cooling rain, the hope for survival.
