Creating the Plum Tree Well in 2022

This is the bottom of the plum tree in April 2022.

This is the plum tree in May 2022 after creating the tree well.

This is the plum tree in November of 2022
This is the plum tree well with crocuses in March 2023

This is the plum tree well in June of 2023.  The June drop of the fruit has not started yet.

 A good source of information for creating a 
  tree well.  Finished making the tree well around the plum tree on the 28 April, 2022.
It has boards along the Pees side to keep his freaking weed eater off the roots of the tree, I hope.  I moved the little yellow leafed veronica -- a piece to the little back rockery, a piece to the front little rockery, and another piece to the rockery next to the pond.  After weeding, somewhat, and cutting back the wild hawthorne bush, I put in the boards with clay backing on my side and some stones and the left over grass stuff on the Pees side.  I stuck little honeysuckle pilea cuttings in along the side of the boards and hope they catch hold.  I added compost from the old bin, and then some leaf mulch from under the bench on top of the compost.  I put in 3 fertilizer sticks around the roots about 4 feet from the trunk.  Still more weeding to do.  It rained overnight on the 29th, so this should all be good.  I may add some more soil of some kind over the leaf mulch to hold it down.  Perhaps some clay from under the deck, with sand added to it. Kept the tree watered over the 2022 year.  Cannot find where we had plums last year, though.

  There was a lot of June drop from the tree, this year, in June.  And still lots of plums on in September.  Some kids were under the tree with their ladder picking plums.  Pat had a word with the people (Syrians ?) next door, and told them that the tree was ours as we planted it and take care of it so they are not allowed to pick the fruit.  Haven't seen any kids there since.  But we came home from grocery shopping a couple of weeks ago and that demented old Pee was out under the tree pulling down branches.  His chair was sitting under the tree.  I was furious.  I had to physically throw him off my tree.  I haven't seen him there since.  We have managed to get quite a few pounds of plums this year, after all this hassle.  I have made 2 batches of plum sauce, each of about 2 cups.  We have had a huge pie with another pie plate of sliced plums frozen.  And then I have 5 more cups sliced and frozen in 1 cup little baggies.  We have been eating them fresh, for about 3 weeks now, too.  So, making the tree well and keeping it watered, despite the drought has been a success.

The taking down of the Virginia Creeper in 2022

 In 2022 we had many renovations done in the garden.  And the heat pump installed. Some of the garden renovations are shown on the composite of the Synopsis of the Journal entries for 2022 included below.  The taking down of the Virginia creeper was not mentioned on the composite... just too many things done in 2022.  As I am starting to do up yet more gardening pages I am doing this post so I can link it to the page about the Driveway Strip garden room 

The text is an excerpt from my daily garden journal.

August 11, 2022: 

 Pat was complaining about the magnolia and the tree/shrubs on the other side of the driveway, including the virginia creeper. He has to get up on the ladder once a year and bring it down so that it does not get up on to the wires. Poor Pat! So after talking to him about taking it out or keeping it; I think I compromised at bringing it down to manageable height. I started this chore at 3:00 and came in at 5:00. I have a lot of it pulled down. There was a squirrel's nest or two under there. It has a lot of dried out vines. The ivy is very healthy. When I got to the top of the vines I see that the ivy has grown into cracks in the post. So, it is a good thing we are taking it down, I guess. I am now contemplating cleaning out the area around the post, entirely. I do not know if round up kills ivy, creeper or St.John's wort. 

August 12, 2022:

 I have the piles of debris along the driveway with the virginia creeper stuff. So, it is quite cleaned up.  I worked at taking down more of the virginia creeper from about 3:00 to 3:40... came in for iced cappiccino and a cookie. Was back out till about 5:45. I have about 3/4 of the thing taken down. Pat and I do not know just yet how much of the creeper we are going to take down. Ground level would be good for me. The lower I go on clipping down the stems the thicker the stems become, so I do not know how much of this I can do with the long handled pruner. It has been a very good tool, but I think this bashing and crashing the creeper is taking its toll on it. This year has been full of this 'taking trees and shrubs down and cleaning up over-grown things', and renovation everywhere. 

August 16, 2022:

Was 18 degrees when I went out to the garden to continue taking down the creeper. I have it down to a knarly bunch of stems that look like a stump. I think I will leave it at that. Need to get the St. John's wort mowed down. Then I should be able to find someone to hall away the debris. The Davey Tree arborist comes tomorrow morning. Pat thinks I should ask them to take this debris... Would be nice if they could. 

August 17, 2022:

Saw Ben from Davey Tree this morning about 10:00 ish. We got all the things listed that I want done: copies of everything in the gardening folder.

August 20, 2022:

 At about 9:00 Ben came by with his silver pick up truck and his tools. He has a good big hedge pruner, rake, shovel, broom and a tarp. Also has a pressure washer and other things I don't know about. He used the tarp to load debris onto, folded it and lifted the stuff into the truck box. He clipped the St.John's wort; on the Saanich property and up to the agave. I said I would do the rest, as there are plants in there that I do not want clipped down. It must have taken him a couple hours. The truck box was full and covered with the tied down tarp. I got his private phone number and his wife's cell. He uses his cell number for Davey Tree stuff, and the ipad they gave him. He uses his private phone with Davey so he does not need to be answering several different phones. $150. paid. 2 more months and he will be able to form his own company. I don't think Davey Tree minds him doing this side work, as long as he is not doing tree stuff that Davey would be able to charge for. 

On August 18, 2023 I dug out some of the ivy at the base of the stump of the virginia creeper.  The creeper has gone wild, with great big leaves that are lying on top of the St.John's wort along the ground. I pulled down the pieces that have grown up the post to about a 6 foot height.  When I get the time I will move the creeper vines and cut back everything beneath them, and put them back along the ground again.   The St. John's wort also has been growing like crazy.

The Salton Sea

 This is a photo from our trip to California in 2018.  We are parked by what is left of the Salton Sea.  In that regard I am copying a recent article that describes the mining of Lithium from the area.

Lithium  fuels hopes for revival on California’s largest lake

August 30, 2021 

Greg Shank hits golf balls onto a dried up boating dock near his home in Salton City, Calif., Wednesday, July 14, 2021. Shank used to sail a boat on the canals near his property, which have since dried up. Increasing demand for electric vehicles has shifted investments into high gear to extract lithium, critical to rechargeable batteries, from geothermal wastewater around the rapidly shrinking body of water. But decades of economic stagnation and environmental ruin have left some nearby residents indifferent or wary. 

CALIPATRIA, Calif. (AP) — Near Southern California’s dying Salton Sea, a canopy next to a geothermal power plant covers large containers of salty water left behind after super-hot liquid is drilled from deep underground to run steam turbines. The containers connect to tubes that spit out what looks like dishwater, but it’s lithium, a critical component of rechargeable batteries and the newest hope for economic revival in the depressed region.

Demand for electric vehicles has shifted investments into high gear to extract lithium from geothermal brine, salty water that has been overlooked and pumped back underground since the region’s first geothermal plant opened in 1982. The mineral-rich byproduct may now be more valuable than the steam used to generate electricity.

California’s largest but rapidly shrinking lake is at the forefront of efforts to make the U.S. a major global player in the production of lithium. Despite large deposits of the ultralight metal in the U.S., Nevada has the country’s only lithium plant, and U.S. production lags far behind Australia, Chile, Argentina and China.

Decades of environmental ruin have left some residents on the Salton Sea’s receding shores indifferent or wary. They have been disappointed before, most recently by solar plants that failed to be the economic engine many hoped.

The Salton Sea formed in 1905 after the Colorado River breached a dike and two years of flooding filled a sizzling basin, earning it the nickname “The Accidental Sea.” In the 1950s, the lake thrived as a tourist destination, drawing anglers, boaters and celebrity visitors including Frank Sinatra.

But storms in the 1970s destroyed marinas and resorts. Flooding wrecked many homes in the tiny, former resort town of Bombay Beach, and after the water dried, left an almost apocalyptic atmosphere that has recently attracted artists.

The lake level peaked in 1995 but, with little rain, has since been evaporating faster than Colorado River water seeping downhill through farms can replenish as farmers conserved more water.

Since 2003, the 324-square-mile (839-square-kilometer) lake has shrunk 40 square miles (104 square kilometers), exposing vast lakebed with microscopic wind-blown dust that contributes to poor air quality and asthma.

The sea has been a key stopover for migrating birds. But as the lake has shrunk, the fish population has declined, chasing away about 25% of the more than 400 bird species that populated it five years ago, said Frank Ruiz, Audubon California’s Salton Sea program director. Carcasses of oxygen-starved tilapia no longer blanket shores periodically with a stench that could reach Los Angeles because there are so few left.

In Salton City, a town of about 6,000, roads curve along empty lots, a legacy of its first developer who stopped construction in 1960. Street signs with idyllic names like Harbor Drive and Sea Shore Avenue mark a barren landscape of cracked pavement.

Pat Milsop, a 61-year-old retired restaurant owner, hits golf balls across a dry canal. His view is filled with dilapidated docks on bone-dry soil that harbored boats when his mother-in-law bought his house in 2004. He is skeptical that lithium will restore some of the lake’s glory.

“Are they going to do something good for the community or just buy up all the land and kick everybody out?” he asks. Nostalgic for livelier days, he plans to move to his farm near Lubbock, Texas.

The lake is at the southern tip of the San Andreas Fault, which has shifting tectonic plates that bring molten material closer to Earth’s surface. The only other part of the U.S. known to have more geothermal brine available is on the fault’s other end in Northern California.

Rod Colwell, chief executive of Controlled Thermal Resources Ltd., oversees construction of what would be the region’s first geothermal power plant in nearly a decade. General Motors Corp. said it invested in the project as it seeks to eliminate tailpipe emissions from light-duty vehicles by 2035.

The lake’s southern shores are dotted with small, volcano-like pots of bubbling mud caused by geothermal activity. In 2011, Colwell walked about a mile in the Salton Sea’s knee-deep water — all of it now evaporated, with a fine powder below a white, cracked crust.

Lakebed is considered an ideal spot for lithium. The company says it plans to drill down 8000 feet (2,438 meters) for super-hot liquid.

“There is no brine resource like this anywhere on the planet,” said Colwell, who relied on years of extensive, publicly available reports analyzing the area’s soil.

He said the $520 million plant will start producing lithium in 2024.

Owners of 11 existing geothermal plants around the lake’s southern shores are retooling for lithium and possibly other brine minerals instead of building from scratch. Warren Buffett’s Berkshire Hathaway Energy Co. has state and federal grants for lithium demonstration projects and says it could begin construction for commercial operations in 2024.

EnergySource LLC opened its geothermal plant in 2012 and its sister company, EnergySource Minerals, has extracted lithium there on a small scale since 2016, said Derek Benson, chief operating officer. It plans to start building a $500 million addition for mineral extraction by the end of March.

An easily overlooked metal structure faces the plant across a two-lane rural road. Bolted down by tons of concrete, it drills more than 4,000 feet (1,219 meters) underground for steam that allows for electricity to be generated and delivered to the Salt River Project, a utility with 2 million customers in central Arizona.

Before it’s pumped back underground, the brine is “borrowed” for a few hours to extract lithium under a nearby canopy, Benson said.

Extracting lithium from geothermal brine has never been done on a commercial scale. There are two dominant production methods: mining for rocks and using cooler brine that bakes under the sun in large ponds for about two years until the water evaporates. The Nevada plant uses evaporation ponds.

San Diego-based EnergySource operates on the former site of Simbol Materials, a heavily hyped company that used geothermal brine and flopped in 2015 after negotiations collapsed over Tesla Inc.’s $325 million offer to buy it. Business decisions caused the company’s demise, according to industry experts and executives affiliated with the latest projects. Technology has since improved, they say, and so have market conditions.

Demand for lithium has soared as more carmakers shift to electric. California has targeted 2035 to achieve zero emissions from all cars and trucks sold in the state. The Biden administration hopes to achieve carbon neutrality by 2050.

“This is the moment where a number of trends, the confluence of them, have finally come together,” Benson said.

Detailed environmental impact reviews, required by California law, have not been released. Benson says his company’s geothermal brine technology uses much less land and about one-fifth the water of evaporation ponds and emits one-seventh the carbon dioxide of rock-mining.

Unique geochemical characteristics bring risk regardless of technology, said Alexander Grant, principal at research firm Jade Cove Partners.

“It’s very easy to fall into this narrative that the technology is not proven, but that is fundamentally not the right way to look at it,” said Grant, a Lawrence Berkeley National Laboratory research affiliate. “The fact is that it’s hard to build lithium projects.”

Smokestacks shooting steam at geothermal power plants are a towering presence amid flat fields of lettuce, melons and alfalfa.

Despite hugely productive land that stocks U.S. supermarkets with winter vegetables, Imperial County has a poverty rate of 22%, among California’s highest. El Centro, the county seat, perennially has one of the highest unemployment rates among 389 U.S. metropolitan areas.

Many farmworkers commute daily from Mexicali, Mexico, to pick vegetables in winter and melons in spring. In the summer, snowbirds flee stifling heat and people stay inside, making towns and fields look deserted.

Lithium has generated cautious optimism. EnergySource expects to contribute $80 million to $90 million annually to the economy, largely through payroll, taxes and royalties. Controlled Thermal Resources is expected to create 1,400 jobs, according to the Imperial Valley Economic Development Corp.

“How do we end up with this great opportunity before us but at the same time not get burned?” said Luis Olmedo, executive director of Comite Civico del Valle, which advocates for low-income and underserved residents, and a member of the Lithium Valley Commission, a state panel to promote the lake’s lithium resources.

The lake depends entirely on Colorado River water gravitating through canals across hundreds of thousands of acres of chemical-laden farms. Amid growth, Arizona demanded its full entitlement of river water, forcing California to end its overuse. In 2003, squabbling California agencies settled on shifting large amounts of the state’s share to San Diego, meaning less water for Imperial County farms and, by extension, the Salton Sea.

Persistent drought tied to climate change raises the prospect of even less Colorado River water seeping downhill into the lake.

Longtime residents miss when eared grebes, cormorants and white and brown pelicans were more abundant.

“The noise was awesome,” said Carlene Ness, 74, who bought a western shore house with her late husband in 1999. “That’s what everybody bought for, and we have to fight for it.”

In Calipatria, a city of 8,000 closest to the geothermal investments, lithium may be the biggest boon since two state prisons opened in the early 1990s. On a stifling July day, a gas station on the main street was the only establishment with activity.

Ruben Hernandez, 54, has worked for an Imperial Valley landowner since he was 8. He and his wife own a Mexican restaurant in the largely deserted town of Niland. His wife wants to stay, but “there’s nothing here, no town,” he said.

Lithium project backers who come for breakfast tell him he could eventually be feeding 20 to 30 people and delivering lunches to their plant.

“If they are going to lift this town up, it would be great,” Hernandez said.
