Premiere of Music Video Parody: No! (That Isn't Recyclable)

Sustainable Tucson Movie Night and Premiere of Our Music Video Parody!  

At a recent Sustainable Tucson meeting, Sherri Ludlam (Environmental Scientist from the City of Tucson Department of Environmental and General Services) informed us that China would no longer be accepting all of our dirty recycling because of contamination. When Alex Kosmider from Sustainable Tucson's Zero Plastic Waste Team heard about the threat to our recycling program, she decided to educate Tucsonans on the proper way to recycle. She rewrote the lyrics of Meghan Trainor's "No" to include what NOT to recycle. Team Recycle was formed to create a fun music video parody.

Join Sustainable Tucson for a fun-filled "Movie Night" and the premiere of No! (That Isn't Recyclable). Our hosts David Fitzsimmons and the Recycling Fairy Nicole Johnson will lead the Q & A with the filmmakers. After the intermission party we will screen the powerful documentary Trashed with Jeremy Irons. Here's the cool part! It will be shown at The Screening Room - where we shot some of the video! So you can enjoy popcorn and drinks in special compostable glasses!

Recycling was never this fun...
  • A demonstration table by Zero Waste Tucson
  • A "Book Exchange." Bring a book you don't read anymore and take a book! (We especially love books on sustainability!) 
  • Game: Stump our resident recycling expert! Bring a piece of trash to see if it can be recycled.
What: Sustainable Tucson Movie Night
When: Tuesday, August 13, at 6 p.m. (Doors open at 5:30 p.m.)
Where: The Screening Room, 127 E Congress St, Downtown. (Near the Ronstadt bus station.)
Price: Free (like all of Sustainable Tucson's monthly meetings) But feel free to show appreciation to our host - The Screening Room - by purchasing concessions or a drink at the bar.

Didn't my figs do better last summer?

Heritage fig trees last July. 
I like to fancy myself a sort of  a "citizen scientist." Well, I like to take a lot of pics of the plants in my yard to see how they are faring in our hot, dry summer...

This morning I was scrolling down Google Photos. My heart just sunk as I noticed that our yard looked greener in summers past. For sure our "drought tolerant" heritage fig trees were doing better.

Here is that fig tree now...

Heritage fig in greywater basin. Coming back a little since the rain. (Those are bean sprouts I planted for added nitrogen.)
Why is our little fig struggling so?  Dan claims it's not even as hot this summer. But he did say that last year the monsoon rains had started by now...  It can't be just the lack of water, because our fig trees are watered regularly by greywater from our washing machine... Maybe the rain clouds give some relief from the scorching sun...?

I got to thinking. I wonder if it's because it's not cooling off at night like it used to. One evening it got  up to 92 degrees! It wasn't always like this. Before there was air-conditioning people in Tucson used to sleep outside to cool off in the summer.

Some plants (and us humans) need that cooling down time to recover from the hot day. It is vital for our health.

Typical profile of the Phoenix urban heat island (UHI) using the five predominant land types
This phenomenon where it stays hot at night is known as the "Urban Heat Island Effect." All of the pavement and cement in our city holds the heat longer. Phoenix has a real problem with this. I wasn't planning to blog about that this morning. But I am concerned that some people want to make Tucson more like Phoenix with more highways going through town! Our small town infrastructure is a blessing! It is one of the reasons it's cooler here!

One way to fight the heat island effect is to plant more trees. And the city is working on that. Mayor Rothschild championed the 10,000 Trees Campaign. That's great because trees cool down our streets and neighborhoods AND sequester carbon to fight climate change. We could sure use some of those trees to line the sidewalks so people have a shady place to walk or wait for the bus.

As we plant all those trees, we need to be mindful of how much water the trees take and where we are getting the water for them. We are living in a desert during a drought.  As much as we love to grow fruit trees, they require more water. To be sustainable, we need to plant more drought tolerant heritage fruit trees or native trees - and use our wash-water and rainwater to irrigate them.

For our part, we dug out most of the gravel in our yard. We planted "durable," heritage pomegranate and fig trees in a mulch-filled  greywater basin and edible native trees in the front yard. (The mulch works with the roots of native grasses to hold the moisture longer). We water the fruit trees mostly with greywater from our washing machine and rainwater collected in the basin. In the summer, I might give them a little extra water from our 55 gallon rain barrels.

Last Sunday we had our first summer shower. Yeah! I try to use up all the water in the blue barrels before the next rain, so they are ready to be filled up again.  I try to do it first thing in the morning before it gets hot and the water evaporates.

We still aren't doing everything we can do. We plan to install more gutters on our roof to direct more rainwater into bigger cisterns and use rainwater from the neighbors roof to water a vegetable garden. (It helps to have a good relationship with your neighbors!) 

To stop the Urban Heat Island Effect, it's gonna take a community effort. We're all gonna have to plant more trees (and maybe drive a little less so we can dig up some parking lot pavement). Right now, there is enough rainwater to irrigate them all, if we all do rainwater harvesting. There are rainwater harvesting rebates and a low income grant and loan program - yet less than 1% of us are taking advantage of them. Why is that? What can we do about it?  I would love to hear your ideas and solutions.

Meanwhile, we can start where we are. Take the first steps. Plant a tree. Start a conversation with your neighbors. Share this blog... :)

"Finishing" Our Catchment Basin: Observing and Re-shaping

Yay! Our neighbors finally get a glimpse of what that "River Run Network" sign refers to. We just had our first downpour right after Dan "finished" our catchment basin!

As anyone who has taken Watershed Management Group's Water Harvesting rebate class can tell you, the first thing you do when you're gonna start an earthworks project is to observe where the rainwater naturally goes in your yard and where it puddles.... 

You can see from the photo (below), that rainwater comes down from the roof and puddles by our front door patio.

Notice: the scorched shrub in the middle. Since we are transitioning to a native food forest, we are replacing non-native shrugs with native ones. Our policy is if the shrubs make it through the hot summer without extra water, they can stay. This one did not.  You can see the durable Texas Sage to the right is doing well (partially due to getting water from the roof.) 

See how the water from roof has dissolved the patio. A reminder that we need to put in some gutters to redirect that rainwater where it can be used. 

Previously... Dan had removed A LOT of gravel and plastic so the water could penetrate the ground. 

He noticed that there was a subtle slope in the yard that was directing the rainwater towards the foundation of our house.  Not good!  But look how green the Cat's Claw  and bougainvillea are! 

He had to use a pick to get through the hard clay. 

Checking out the shallow basin. 

Dan got to use some of the red gravel he dug out of the backyard to make a decorative trail...

After putting in a path of red gravel, Dan saw that the basin still needed more shaping....

Hey, it's a process! A process of observing and adjusting to make the best use of the rainwater.

Dan used some of the gravel he had previously dug up to build a mound protecting our foundation with a gravel trail. 

While digging the basin by the little sage (and a dead native plant), we probably overdid it a bit...

Looks like we need a thirsty shrub in that basin! 

NOTE: You should never plant a native tree (like paloverde or mesquite) on the bottom of a basin that holds that much water. They could get root rot and fall over. 

So when shaping your yard to use rainwater, it's good to keep observing during the monsoon rains. (One of our favorite things to do anyway!)  

You can see from this video taken on Sunday, July 14th, that a lot of water is coming down from the roof over our carport. That water should be rushing out of the downspout. So we either need to clear out the gutter or install a bigger one.  Another project! 

A row of  edible jujube would go great where Dan removed the non-native oleanders! Mo' projects! Mo' projects! 

Our "finished" basin...

Well... until the next downpour informs us.

Thunder Teases of Monsoon Rain

The distant rumble of thunder gave us a smattering of hope that the much needed monsoon had finally arrived. But after a few sprinkles, the clouds rolled on. Such a tease! The fickle rain tickled another neighborhood instead. 

cactus trying to escape the heat
Monsoon season can't come soon enough for us....

You know it's bad when your cactus can't hack the heat!  Even the decorative metal animals seem fatigued. (Or is it just me?)

I know, I know...I heard. The monsoon will be late this year.

"The weather systems that kept the area cool in the spring also suppressed high pressure from moving north into the Four Corners region that brings the necessary heat to build monsoon storms in the area. A thunderstorm requires moisture and heat. Without heat to combine with the moisture, thunderstorms won’t come to Southern Arizona until later in the summer, as the high pressure starts to slowly move north," announced meteorologist Jeremy Michael.

Is Jeremy saying it's not hot enough!  Despite extra mulch and water, this "drought tolerant" heritage fig is down to it's last leaf!

The long hot summer (yeah, I know it's early July) has taught me a thing or two - like maybe those baby figs need some shade covering like the loquat in the background.

And it taught me to be resourceful....

As a result of the late monsoon, I was disappointed to find no purslane growing in our alleyway.  (It usually requires 2 or 3 downpours to sprout.) But I did notice purslane popping up by the emitter at a certain Korean restaurant in our neighborhood. I grabbed a handful of these edible weeds by the roots. I always wash purslane over a bowl so I can pour the little black seeds where I want them to grow in my yard.

So after enjoying the yummy leaves and stems, I planted those seeds and the roots in the basin by our loquat tree.  I figure while I'm cooling off our thirsty loquat, I might as well get double duty out of that water. While I was at it, I went ahead and soaked some beans and planted them there to put nitrogen in the ground. Six beans sprouted. There's one left after the lizard had it's share. Here is what he left of the purslane...

As my bare feet sizzled in the morning sun, I decided I had to do something for the poor bees and birds. I set up a makeshift birdbath - a tomato cage holding a Pyrex pie pan. 

magnifying glass or bird sauna? 
But it was so hot! I was afraid the clear Pyrex might act as a magnifying glass and start a fire - or at least heat up a scalding bath. 

My solution was to purchase a metal plant stand ($20 at Ace) and a terra cotta clay pot bottom ($10.)  I re-purposed some spiritual message rocks (from a super-loud meditation fountain that an ex-boyfriend got me) to place on the bottom for bees to rest on while they drank. Success! The terra cotta pot keeps the water nice and cool. 

On the bright side, the heat showed me which plants were really drought tolerant. Our desert-adapted heritage pomegranate is hanging in there nicely. (It does get more shade than the figs...)  Our Mexican Honeysuckle are surviving on just  rinse water! Dan's Charlie Brown mesquite tree is flourishing without any extra water. (See last pic below.) And our moringa have come back from the roots (after dying in the deep freeze). Some of the bottom leaves have yellowed. Perhaps they are using their resources to support the new blossoms?!

Another benefit...the delayed monsoon gave us plenty of time to prepare for planting the rain. 

With only a straw sombrero to shield him from the sun, Dan spread out the last truck load of mulch in our front yard basin.
