It’s not just our trees that are dying but trees everywhere, headlines an article in The Guardian (issue of 19 September 2016, written by Oliver Milman in Oahu and Alan Yuhas in San Francisco).
In Hawaii, on the big island, in 2010, the iconic ohi’a trees – a rainforest evergreen — started dying at an astonishing rate. After almost six years nearly 50,000 acres of native forest on the big island are infected, and there is the potential for major deforestation to a whole family of metrosideros trees and shrubs of the Pacific. It is caused by a beetle carrying a pathogen (dark creeping shades of Moana!).
In other areas of the tropics, disease threatens banana plantations, coffee growers are dealing with fungal attacks that reduce yield and kill the plants that produce the coffee bean, and citrus greening is a threat to citrus growers worldwide.
In California an invasive pathogen called Sudden Oak Death – distantly related to the cause of the 19th century Irish potato famine – is infecting hundreds of different plants, including redwoods and ferns (but …but…it’s called oak death): 66 million trees have been killed in the Sierra Nevada alone. SOD is caused by phytophthora ramorum. Despite its name the pathogen slowly saps the life from oaks over two to five years. It is spread mostly through water, like rain splashing off an infected leaf, or wind driven rain that can carry the pathogen for miles. Whole mountainsides have died.
In the Midwest, from Texas to Minnesota and east into Ohio, trees are dying. Ashes succumb to ash borer, oaks succumb to oak wilt (as we know to our regret through the loss of old growth red oaks in Forest Hill Park), caused by the fungus Ceratocystic fagacearum, and to opportunistic insects like the Two-lined Chestnut Beetle.And now something is affecting our native beeches. Meanwhile In the Pacific northwest, bark beetles and pine beetles are killing trees. Five years of drought starved trees of water and weakened their defenses. The beetles that used to be held in check by wet winters now have more time to roam beyond their normal territories, expanding from British Columbia to the Yukon border. Meanwhile, across the Atlantic, the iconic English and European beech forests are also threatened by climate change, especially drought. For us here, weather – mild winters possibly? – may not kill off the two lined chestnut borers the way a bitterly cold winter would, hastening their spread.
What seem like small changes to us – the shift of a degree or two, the lengthening of fall and the earlier spring onset of spring by a just few weeks (which feels beneficial to us – who doesn’t appreciate a milder winter around here?) — can have profound negative cascading affects to ecosystems which depend for communal health on everything living in a balanced equilibrium of competing and cooperating interconnected organisms, both above and below ground.Events like a long and too-wet spring, followed by a longish period of drought, such as we had here in northeast Ohio last year, which affected the prairie states even more severely, stress trees, leaving them vulnerable. They live lives many times longer than ours, but are slow to adapt.
These changes to climate – that seem so unremarkable to us, or even good as we enjoy that mild winter day – naturally affect all components of an ecosystem, and there are parameters beyond which any ecosystem becomes destabilized and the natural equilibrium of the healthy ecosystem is sent awry. I believe we laypeople inadequately appreciate this. Probably new equilibriums will be established over an extended time, but we, personally, probably will not live to see it. Recent reports suggest as much as 80% of species may be on a path to extinction…. and we? We are who understand – we who care? Galadriels, sadly looking at the world we love, knowing that much in it that is wonderful will pass away.

This edition of Gardenopolis Cleveland marks our third summer on the beat. One of our first stories was about GardenWalk Cleveland …and here we are again! Last year there was no garden walk, but they were back up last weekend and even added an additional territory, North Collinwood. Your intrepid editors Catherine Feldman, and moi, Elsa Johnson, drove up to what felt to us like another country. …. perhaps somewhere on the Baltic? We got out of our car on a road where the houses all look out over a private park over looking our inland sea…breezes we’re blowing. It was a small place of summer heaven. A treasure! Why don’t more people know this is here? ! Enjoy,…
Our co-editor, Ann McCulloh also went on Garden Walk Cleveland, to West Park on Cleveland’s west side. But she also manned a table in North Collinwood, and had the chance to take in a few gardens…by luck, she saw the one we missed.
We’re sorry we didn’t see more of Garden Walk Cleveland…. it’s just so big and sprawly that — even though it is open over two days, the idea of seeing the whole thing is daunting. We wonder what it would be like to break them into groupings and spread them out over the course of the summer…?
Chaetura pelagica, voracious eaters of all flying insects, like mosquitos. These birds, native to the Americas, spend the winter (as I would like to do) in South America (northwestern countries), but breed in North America during our summers. Their range is from the Rockies eastward to the Atlantic and northward into lower parts of Canada. Like all swifts, they are incapable of perching, but instead cling vertically to surfaces. And this is where chimneys come in.
A swift spirals down to its roost opening from above. Originally these birds roosted and nested in trees. While they are diurnal foragers, able to stay afloat in the sky for hours, the time I am most aware of them is in the liminal hours of dawn and dusk. They are easily recognized, with their strange short, neck-less bodies, long slender wings, swift erratic flight and chittering call, but they are also easily mistaken for swallows (hence the name confusion). Able to drink and bath on the wing, they are one of the swiftest of birds.
They have extremely acute vision and interestingly, can focus with one eye or both eyes, and, like our native whippoorwill, which they somewhat resemble, they have a huge mouth gape — the better to eat you, little flying insect – but they are sociable rather than solitary, and many birds – sometimes hundreds – will share a roost.In that roost there is only one breeding pair, mated for life.
Although originally cavity-in-tree dwellers, since the arrival of European colonists – and chimneys – these birds now almost exclusively use chimneys (and air shafts, isolated corners in lightly used buildings, and the walls of cisterns and wells). Here’s the catch, however: today many of us cage our chimneys, thus preventing chimney swifts/swallows from using them.
In 2010 the International Union for the Conservation of Nature changed this bird’s status from LeastConcern to Near Threatened. Its population has declined precipitously across the majority of its range. The causes of its population decline are unclear. There may be contributing factors besides loss of roosts.In the U.S, the chimney swift is protected and neither birds nor nests can be removed from chimneys.
How can you help? You can build a chimney ‘swallow’ tower.
This tall slender structure offers an alternative to chimneys. It is usually placed to allow easy maneuverability to descending birds, in an open field, or in a yard, in an open area…. but could also be placed, it seems to me, on a flat roof or deck. They can be big or small. As with chimneys, some maintenance is required. You can find plans on line; look for chimney swift houses.
Not to put too fine a point on it, but Mycorrhizal Planet, a new book by Michael Phillips, is a true breakthrough book, one that will provide new, valuable information for every serious organic gardener.The book describes how mycorrhizal fungi work with plant partners and gives detailed, practical information on how to maximize the power of fungi in all sorts of gardens—from backyard tomato patches to full-fledged agroforests.
The book combines a distillation of extensive scientific literature with decades of the author’s hands-on experience growing fruit and other crops. [As chance would have it, I just completed an Ohio State mycology course last fall and wrote my class paper on Maxmizing Positive Fungal Power in the Food Forest. So I know a little of the difficult scientific terrain Phillips had to traverse.]You would expect such a book to be densely packed, and it is. But it is also logical, good-humored, and down-to-earth, which should be more than enough to lead the committed gardener down a productive path toward a new set of best practices.
We need them.
The 20th Century produced some of the most brutal wars in history, but none so little noticed or comprehended as its War on Soil.Some background and at least a partial explanation of why the War on Soil was so unwitting:
Soil, understood as something orders of magnitude different than mere dirt, consists of minerals, dead organic matter, and multiple living organisms that are often measured, breathtakingly, in billions per teaspoon.Of these organisms, mycorrhizal fungi form the connective tissue on binds most plants. Their hyphae—microscopic filaments—exude chemicals that dissolve potential food—from minerals to wood to dead insects—and then capture it by forming the equivalent of a new stomach wall around it.See the graphic below where the red represents all the fungus’s external chemical activity. As its “stomach wall” expands, the fungus burrows its way tens of meters from its point of origin, all in the search for more food.
Much of the food it seeks, however, is not for itself, but for its plant partners.In return for the phosphorus, nitrogen and other elements our fungus gathers, it trades them in for plant sugars.These provide the fungus energy to expand and capture still more plant nutrients. Put simply, mycorrhizal fungi extend the reach of plant roots by factors of 10 or more—costing the plant far less energy than if they had to expand their root system to cover the same territory.
Fungally-derived nutrients are so important to plants that they may devote one-third of all the sugars they produce to feeding fungi. It is no exaggeration to say that this trading system forms the core of life on earth.It has been in place since both plants and fungi crawled their way out of prehistoric seas. The relationship is so tight that mycorrhizae and plants have evolved to cooperate at the cellular level with the most prevalent mycorrhizal type—arbuscular mycorrhizae—actually penetrating the cell walls of a given plant root.
But that’s only the beginning.Individual fungi merge with other members of their own species to further increase their reach.The resulting network forms microscopic highways for beneficial bacteria to travel the landscape. https://www.youtube.com/watch?v=AnsYh6511Ic And fungi emit a soil protein called glomalin which binds soil minerals and organic matter loosely together in a way that allows the overall soil complex to both breathe and retain water.We call the resulting aggregation soil “tilth” —-the exact opposite of that gardening curse: soil compaction.
Surprisingly, much of this knowledge has only emerged recently.Glomalin, for example, was identified by a U.S. Dept. of Agriculture scientist in 1996!
It is this tightly-woven mineral/fungal/plant interrelationship that 20th Century agriculture and horticulture ripped apart.Tillage and plowing chopped up all those fungal hyphae. Artificial fertilizers fooled plants into happily dropping their partnership with living food providers (sort of like satisfying children with a perpetual diet of macaroni and cheese!).Disconnection from fungal partners, however, limited the availability of trace elements that fungi help scavenge.These trace elements—molybdenum, boron, etc.–are essential to full plant health. Fungally-trapped soil carbon also disappeared.All together, the negative cascade of disappearing nutrients left a void that growers filled with ever more fertilizers, pesticides and herbicides.The ultimate result: ever less nutrition for both plants and their human consumers.
Phillips explains our downward agricultural slide in nuanced detail. But his greater emphasis is not on what went wrong, but how to make one’s own garden right. The three chapters (“Provisioning the Mycorrhizosphere,” “Fungal Accrual,” and “Practical Nondisturbance Techniques”) that make up the bulk of the book tell how to energize and expand fungal networks.
The committed gardener will find numerous possibilities for fungal enhancement of soil, ones that will require rereading and also rethinking of one’s approach to gardening.Out of dozens and dozens ideas the book offers, here are a few that I’m either implementing now or plan to in the near future.
Ramial wood chips.These are wood chips made from fresh twigs and branches, the ones where a tree’s most recent growth has occurred. As one might expect, such high growth portions of the tree carry the highest concentration of nutrients—calcium, phosphorus, nitrogen, etc.Fortunately, these young branches are often the ones professional arborists insert into their chipping machines and which they often have to pay to dispose of as landfill.So it’s easy to persuade neighborhood tree cutters to dump a truck load.I’ve done that and the chips have made my soil darker and richer and my plants happier.
Direct feeding of mycorrhizae by air-knifing holes in the soil under a tree’s drip line, then injecting (often proprietary) fungal food.I had this done last fall to reinvigorate what my arborist diagnosed as oxygen-deprived oak trees.The result: more vigorous-appearing oaks, but also a tripling (!) of fruit production of my pawpaw and peach trees planted under the oak’s drip line.
Planting of what Phillips calls “bridge trees.”These are trees planted specifically to connect more of the separate fungal pathways of a given orchard or food forest and thus, as fungal networks tend to do, share nutrients to those plants which need them most.Fruit trees typically work with arbuscular mycorrhizal partners, while oaks, maple and hickory work with ectomycorrhizal partners. Typically those two groups of fungi don’t “talk.” But a few tree species—willows, poplars, alders—partner happily bridge with both fungal communication gap. Within a broader landscape, they and their fungal partners open the possibility of tapping a much wider nutrient pool.So I’ve begun to encourage alders—already self-seeding to some extent in my food forest—by planting more in strategic locations.
As readers can now gather, Phillips goes into considerable detail.Yet what makes the appearance of this book especially exciting is how readablethe author is able to make it.
A typical passage will begin close to the “duh” level of simplicity; e.g. “Mycorrhizal fungi are the principal means plants have for obtaining phosphorus…the middle letter in NPK as represented by those three omnipresent numbers on a bag of fertilizer.”But then Phillips escalates quickly into a discussion of slow- vs. fast-release phosphorus and the relative “cost” to the plant of exuding organic acids to feed phosphorous-gathering fungi.Similarly, when Phillips must dip into scientific language—like “anastomosis,” the merging of separate fungi—he always defines it in understandable terms.
So, readable, yes, but also dense and complex.
Did I mention that this book is for gardening nerds?

While in DC for the march for climate action I also visited the Sidwell Friends School, where my husband’s cousin, David Mog (an ex-Cleveland-ite), taught math for many years. Though now retired, he is still welcomed back at Sidwell Friends, and so I got a tour of the school complex. David had told me about the waste water recycling project that Sidwell Friend’s installed several years ago and which I’d expressed an interest in seeing up close and personal (well – not too).
It is a complex system in which the water from toilets flows first into a sort of settling tank where the solids settle out. Then the liquids flow into a series of three hillside, heavily planted leach beds. As it passes through the plants of each leach bed it gets progressively cleaner. Supposedly after flowing through the third leach bed, it is safe and clean and can be recirculated.At Sidwell Friends it is reused again and again. By being circulated back to the toilets it proceeds thus in a continuous cycle. Impressive! There is really nothing to see – and definitely nothing to smell – except plants.
As part of the educational aspect a cylinder was installed at the top of the terraced slope that charts the flow of the water. This shows how the system works. Of course there is a good bit of unseen infrastructure of pipes, etc., in a basement which I did not visit.
In the same location, at the bottom of the slope is a rainwater catchment pond that captures rainwater off of the roofs of several of the more recently constructed buildings surrounding the site.The runoff rain water flows through a variety of runnels and tunnels, mostly aesthetic, and then flows into a catchment pond, which has fish. The day we were there I believe there was a problem with the filter and so the system was getting tweaked a bit by the firm that manages it.There was a young (by my standards) man working in the water and David had a good talk with him while I wandered around taking pictures.
The Sidwell Friends complex was also interesting for using its sloped site efficiently — putting playing fields, in one case, on top of a garage, and in another on top of the gymnasium.
After the visit to Sidwell Friends Elsa and David drove past the Kushener/Trump home which is in the same neighborhood as the new Obama digs (a few short blocks from each other), which we also tried to drive past, but the access road was (is) blocked as Obama is still heavily guarded by security, for his own safety. We did a little DC tour and talked about what may be Elsa’s next DC sojourn in September, the Interfaith March. We shall see.
As part of its summer long Centennial Celebration, the City of South Euclid will host GardenWalk South Euclid on Saturday, July 22nd, and Sunday, July 23rd, from 12 noon to 4:00 pm. It will serve as an annual legacy to the Centennial Celebration. The GardenWalk was co-founded by Northern Ohio Perennial Society members, Donna M. Zachary and Sue Gold, and the planning was started in the fall of 2015. Over 35 private gardens, three pocket parks (a Meditation Garden, a Tranquility garden and a Perennial Reflection Garden), a 21 acre nature preserve (hourly tours), 7 mile wetlands and over nine unique community gardens are on the GardenWalk. One community garden contains a bio-retention water basin and two are located in park settings. All can be explored during this “free, self-guided”, two day event. The city’s theme, “Come Together and Thrive,” can be seen in the many shops and restaurants along the garden route. After July 1st, the maps can be downloaded at www.cityofsoutheuclid.com or www.facebook/southeuclid.com. Maps will also be available at the South Euclid Community Center and the South Euclid-Lyndhurst Library after July 1st. During the GardenWalk, on July 22nd and 23rd, the maps, rest rooms, water and parking will be available at the Community Center at 1370 Victory Drive, South Euclid 44121 from 12 noon until 4:00 PM.
We’ve missed a couple postings, and we apologize. We (the editorial board) confess to being political creatures for whom climate change is a very real and very present (as in right now!) issue, and the direction this president has chosen in response to this issue – i.e., to deny it, and wipe out the EPA – has had us (some of us more than others) spinning off in various activist directions ever since the inauguration. Most recently two of us (Catherine and Elsa) traveled to DC for the Climate Action March (where it was a hot! hot 91 degrees! – a record high for the month, and the month itself a record high for DC).
We joined the group, Elders for Climate Action for the march itself (200,000 people strong) and, briefly, for a conference at the Capitol the day before, at which Maryland representative to Congress, Jamie Raskin spoke. Someone who ‘gets it’. Several days later Catherine attend another conference ( Consultation on Conscience ) at which the young firebrand progressive Joe Kennedy III (grandson of Robert Kennedy) spoke — another person who gets it. These speakers gave us hope (alas, short lasting).
Yes, the march and those activist activities took priority, but while we were there at the Seat of Empire we also spent time doing the very Gardenopolisy thing of looking in on almost all the gardens attached to the various and many cultural institutions around the mall and taking lots of pictures…. and these pictures tell a story about how the focus of landscape in these important public spaces is now about gardening with native plants.
We can only applaud.When Elsa was there in February for the Women’s March – 500,000 people strong – it seemed like every green space was being trampled, and it was hard to imagine anything withstood that trampling, but as you can see from our pictures, the landscapes look great.
One sometimes forgets the distances between the Capitol building at one end and the Lincoln Memorial at the other (yes, this 73 year old walked the entire distance – it felt like more than once). Just crossing the width of the Mall is a trek on a 91 degree day. The monumental scale is such that one could use a horse.
I (Catherine) bring two key points from my conference that are eminently applicable to Gardenopolis Cleveland. First, we were told over and over again by politicians and activists that the voices of citizens are heard by our elected officials in Washington. We were encouraged to speak out, especially in person. Attending town hall meetings and participating in marches does make a difference. Phoning, writing and signing petitions have an impact. We do not have to wait for our next opportunity to vote. Officials in D.C. are harried by the confusion caused by Trump and his administration. They need our support. When someone does something right, let them know.
Secondly, we were encouraged to become active at the local and state level. We can fight for the environment here at home, relatively untouched by what is going on in D.C. and we need to do so. So, what can we do? Gardenopolis Cleveland would like to open that conversation. Please respond in the Comments section about what you are doing, what you would like to be doing, and any of your own organizations that need help.
