Freedom Park Master Plan

I’ve been living in Freedom Park for 20 years.

That’s to say, not a day goes by when I’m not walking somewhere in the park, throwing a ball for our dog, pruning some trees, removing invasive plants, planning a new tree planting, or supervising a project to plant and maintain trees.

Poplar Circle? There are trees in that section now 50 to 60 feet tall that Tree Watch and Trees Atlanta planted together. The playground is surrounded by our trees. The memorial grove tucked behind the playground some of us boldly created on an ask-for-forgiveness-not-permission model. The serpentine paths leading down to and up from Austin Avenue are shaded by trees we planted in the past two decades. Ditto the other side of Highland. Ditto trees all the way along the Freedom Park Trail into Candler Park.

Every tree of ours has a unique personal history. I can tell you the life story of the American linden near the MARTA parking lot. The Harold Saether memorial white oak. The katsura planted by the late Oreon Mann. I’ve watched our longleaf pine since it was knee-high to a baby. You get the point.

Those are my bona fides. And now I’m here to tell you that I am VERY excited about the Master Plan for Freedom Park. Years ago I began discussing with members of Freedom Park Conservancy some ideas for additional tree plantings and projects in the park. They told me, “Sounds great! We’re going to be working on a master plan soon, so let’s make sure that’s considered.” Now here we are, making excellent progress toward the next level of excellence for a park created in significant part by the hard work of people in this neighborhood.

❤️ Weed Trees ❤️

Here’s a dictionary definition of a weed: “a wild plant growing where it is not wanted and in competition with cultivated plants.”

That definition leaves out a lot, doesn’t it? You hear the word “weed,” and somewhere in your mind you’re probably thinking “annoying” and “unsightly.”

People talk about “weed trees,” too. They spring up on their own, often in places where other trees may struggle to thrive or even survive. They’re exceedingly common. They may have characteristics that don’t fit the classic image of a tree, e.g., they may be bushy, misshapen, etc. And they’re scrappy: they can out-compete trees that we think of as conventionally beautiful, stately, grand, majestic, noble — all that good stuff.

Boxelder (Acer negundo) comes to mind. It’s a species of maple native to North America. Check out this guy. Talk about scrappy:

Here’s its compound leaf with leaflets (7 here but can be as few as 3), to help you identify the tree :

Weed tree? Yet entomologist Doug Tallamy says 285 species of Lepidoptera (moths and butterflies) rely upon boxelder to survive their caterpillar stage.

So many bugs! Here’s the secret: boxelder is terrible at doing what many other trees do incredibly well, which is to seal off decay. Which means that boxelder rots. And what loves rotting wood? Bugs!

And birds love bugs, of course. So boxelder indirectly feeds lotsa birds, too.

Can you build a beautiful, long-lasting dining room table out of boxelder wood? Nope. But can you sustain an ecosystem encompassing hundreds or perhaps even thousands of different insect and animal species with boxelder trees? ? Yep.

Yes, those are boxelder seedlings, bringing a stone staircase to life. Not bad for a weed.

Memorial Day 2021

In Marietta National Cemetery there lie not quite 19,000 graves of men and women who served their country. One of them is my uncle Robert Northington Hardeman III, known to his family and friends as Bobby.

He died, still a teenager, during the Battle of Saipan (June 15-July 9, 1944) in the Pacific.

Marietta National Cemetery, like many cemeteries, is a tranquil site, where many of the graves are shaded by mature trees.

Those trees are chestnut oak (Quercus montana), which is in the white oak grouping of oak trees.

The leaves of the chestnut oak have many shallow lobes, not unlike the leaf of a chestnut tree.

By the way, you do know how many wonderful trees you can find at Oakland Cemetery, don’t you? About 1,600, in fact. It’s a marvel. I highly recommend a walk there, sometime soon.

EWW!

It’s that time of the year.

Chinese chestnut (Castanea mollissima)
Spiky flowers of the Chinese chestnut tree, called catkins.

A large Chinese chestnut tree (Castanea mollissima) is in bloom near my house, and it’s once again filling the air with an . . . ammonia smell which is seriously unpleasant.

The culprits are nitrogen-containing volatile organic compounds (VOCs) which include (for you chemists out there) 1-pyrroline, 1-piperideine, 2-pyrrolidone, and phenethylamine.

Chemical structure of 1-pyrroline

What’s the deal? Presumably the tree evolved this smell to attract pollinators. A recent scientific study of Castanea mollissima in China identified the chestnut’s pollinators as flies.

Those researchers suggest that we should add Chinese chestnut to the list of plants that rely upon sapromyophily for a reproduction strategy.

That is, this tree emits a smell that deceives carrion flies into believing that they’re visiting rotting flesh.

Eww.

Naturally, I cannot help but imagine what it must have been like to be out in the forest when the mighty American chestnut (Castanea dentata), erstwhile queen of the mountainous forests in the eastern U.S., was in bloom.

And, hey, I’d happily cope with a couple of weeks of that yucky odor to have those trees back, safe and sound from the chestnut blight.

Katsura

The next time you’re in the Poplar Circle area of Freedom Park, pause to admire this beauty.

Katsura (Cercidiphyllum japonicum)

Katsuratree comes to us from Asia — Japan and China to be precise — and we have this gentlemen to thank:

Thomas Hogg, Jr. (1819-1892)

Beginning in 1862, Thomas Hogg, Jr. was stationed at a new U.S. consulate at Kanagawa, south of Tokyo. The man knew plants. His father, an emigrant from Scotland to New York City, had operated a nursery on the site of today’s Madison Square Park (Broadway and 23rd) in Manhattan. Thomas’s brother James took over the business after their father died.

Immediately upon arriving in Japan, Thomas Hogg started sending home seeds of plants entirely new to North America. In the 1870s, he made a second trip to Japan and continued his collecting.

Everything from our wonderful Japanese maples to our evil, evil kudzu vines can be traced back to the industrious Mr. Hogg.

Inman Park is simply full of Hogg’s legacy, good and bad: fragrant snowbell, Japanese snowbell, Kousa dogwood, varieties of camellia, ‘Limelight’ hydrangea, oriental bittersweet, Japanese knotweed, and more.

He was justly proud of having introduced the katsura to these shores. Its botanical name is Cercidiphyllum japonicum (because its heart-shaped leaf is similar in shape to our redbuds, the genus of which is Cercis).

Katsura leaves (note the reddish color of new leaves)

In its natural habitat, katsura can grow quite large and live a long time. A man named Charles Sprague Sargent, who was the first director of Harvard’s Arnold Arboretum, had a photo taken of this tree on his trip to Japan in 1892. See how older katsuras tend to develop multiple trunks:

In fact, there’s a katsura on the grounds of the Arnold Arboretum with just such multiple trunks. This tree was grown from seed collected by another 19th-century botanist, a man named William S. Clark, during his 1876 expedition to Japan:

Arnold Arboretum katsura

There’s lots to love about katsura. Check out this fall foliage:

Katsura in autumn

Also in fall, the leaves emit a smell similar to caramel or cotton-candy, though not everyone can smell it. It’s generated by a chemical compound called maltol, which is also emitted by such items as bread, warmed butter, chicory, and cocoa.

Tale of An Oak Tree

When Jeanne and I moved into our Waverly Way home, back in the year 2000, there stood a huge water oak (Quercus nigra) between our house and our neighbor to the east.

Several years later, that oak died, and so our neighbor had to take it down. But it left some acorns behind!

In 2010, you can just see a sapling poking its head out of the bushes, in front of the flowering dogwood:

The next year, it’s making a bit of progress, though it’s hard to pick it out among all the other volunteers.

By 2014, with its root system just the way it wants it, the oak has leapt up.

Here is the tree now, on May 22, 2021. Roughly a decade of growth. It’s more than 60 feet tall. Look to the left. That’s a white oak (Quercus alba) that I myself planted probably five years before that water oak even thought about germinating.

Sixty feet tall in 10-12 years!

Splinting

I visited a lovely back yard today. It belongs to our neighbors the Crouses.

(As our recent Tour of Gardens revealed, back yards are definitely where it’s at in Inman Park.)

Four years ago, Marge and Gray invited Tree Watch to plant a blackgum (Nyssa sylvatica ‘Wildfire’), ginkgo (Ginkgo biloba), and a Shumard oak (Quercus shumardii) in their back yard, as well as an American linden (Tilia americana) in the sidewalk planting strip out front.

We said, “No way.”

Just kidding. We said, “Fantastic!” In fact, here’s our friend Chris Hrubesh finishing up his planting of their oak tree.

The Crouses’ trees are thriving. That oak in the photo is probably 15-18 feet tall now.

But Marge and Gray did report to me that their ginkgo, for reasons only it knows, had decided to start growing sideways at a point about four or five feet off the ground.

A word or two about the remarkable ginkgo or maidenhair tree. Here’s the introductory paragraph from a 2020 New York Times article:

The ginkgo is a living fossil. It is the oldest surviving tree species, having remained on the planet, relatively unchanged for some 200 million years. A single ginkgo may live for hundreds of years, maybe more than a thousand. They’ve survived some of our world’s greatest catastrophes, from the extinction of the dinosaurs to the atomic bombing of Hiroshima.

They’re amazing trees! Check out the beautiful specimen in front of The Natalie on Waverly Way. This ginkgo at the High Museum is another fine example.

Notwithstanding how impressive a mature ginkgo tree can be, young ones are slow-growing and often gawky. For years, they just sit there looking goofy. Eventually, when they’re finally ready, they start putting on one to two feet of new growth each year. And so I suspect that when that time comes, the Crouses’ tree will straighten itself out.

But I can’t be sure. And so I decided to splint the tree for a few months.

In tree parlance, splinting is not staking. We stake a tree primarily to stabilize it while the root system develops.

Source: Urban Tree Foundation and International Society of Arboriculture

We splint to straighten out the trunk or a branch. As you can read in the upper right-hand corner of this photo, a bamboo pole is tied to the trunk without being driven into the soil.

I tied two bamboo poles together, and then with Marge’s help, attached the bundled poles to the ginkgo in three places. I used a pieces of a soft, flat, polypropylene strap and some felt that Marge happened to have.

With the weight of the splint attached, however, the tree needed to be staked, which you can see here.

It’s never ideal to make a tree rigid. Movement is an important factor in ensuring a tree’s proper development as it grows. So I’ll be removing the splint and the stakes as soon as the tree adds enough annual growth rings to hold the tree in the corrected position.

Wish us luck.

Sign the Inman Park Leaf Blower Petition

Gas-Powered Leaf Blowers in Inman Park

Residents of Inman Park in Atlanta, Georgia, should voluntarily restrict their use of gas-powered leaf blowers (GLB) to the following times and days: 10:00 a.m. to 4:00 p.m. from Monday to Friday, noon to 4:00 p.m. on Saturday, and not at all on Sunday.

Noise from GLBs is a source of unhappiness and inconvenience for many Inman Park residents. More than that, GLB noise can damage human health as well. The CDC, the EPA, and OSHA all identify leaf blowers as a source of harmful noise. Among the people most at risk are those who work from home, people who work night shifts, children, the retired, the elderly, the sick, and of course the landscape crew itself.

It's not just humans. A scientific study in 2018 found that the noise we humans generate affects wildlife, too. It alters stress hormones in birds, for example. One consequence is that chicks nearer to noise tend to be smaller, with poorer feather development.

Other negative effects of GLBs are well documented, especially with regard to air pollution. You could drive your car, with its efficient pollution-control technology, all the way to California, and you still wouldn't come close to producing the same amount of certain pollutants as GLBs create in the course of an ordinary day of leaf-blowing in Inman Park.

Alternatives to GLBs exist. A battery-powered blower is one example. More and more yard maintenance companies are going all-electric, including in Atlanta. Moreover, hundreds of cities and towns have already adopted restrictions on the use of GLBs.

By signing this petition, you are pledging to limit your GLB use (if any) to the specified days and hours, and you are encouraging others to abide by these modest, voluntary restrictions as well.
