Perfect Earth continues to expand our Pathways to PRFCT program, a network of diverse public gardens and parks, managed for health and well-being, beauty, biodiversity, and sustainability. I’m happy to announce that Wethersfield Estate and Garden in Amenia, New York, is our newest partner. Conservation has been at the heart of the 1000-acre estate since it was established by the late Chauncy Stillman more than 80 years ago. He helped shape modern farming techniques by enhancing soil health, reducing soil erosion, and promoting water conservation. Today, the estate features an elegant Italianate garden with more than 20 miles of trails and over 400 acres of woodlands. Upholding that spirit of conservation, the horticulture team is now designing flower displays so there’s always something blooming for pollinators, planting more natives, especially keystone species, and removing invasives on the property. They’re also saving resources, limiting watering to establishing new plants and in times of drought, and retaining biomass on site. We’re especially pleased to welcome them because Perfect Earth's Toshi Yano helped revitalize this garden as their director of horticulture from 2019 to 2022, starting many of these methods. We hope you will visit to see the beautiful results of these nature-based practices.

Radicle Thinking by Edwina von Gal
This post is about roots. It also marks the start of the new name for my Perfect Earth monthly posts: Radicle Thinking. The radicle, a root, is the first thing that emerges from a germinating seed, and the future of a plant depends on the radicle’s success. Seeds, miraculous tiny germs of life, are held in suspension until the world around them says, Okay, GO! A radicle then sets out to explore and engage with what it finds. It heads down into the soil to anchor the new plant, and then starts sending up water and nutrients so the plumule (the embryo’s shoot) can grow up towards the sun and start the true leaf growing process.
The radicle and the lateral roots that follow it form a root system of insanely intricate and mutually beneficial relationships with the microorganisms in the soil. These root systems form part of a two-way delivery system: nutrients and water from the soil flow up into the leaves, while sugar made from sunshine (photosynthesis) is sent down from the leaves to the roots to energize a vast community of busy soil-based lives. Roots+soil+leaves+sun = the essential building blocks of plant life.
My interest in roots and radicles makes me think about the fact that few of our commercially available plants are grown from seed. Most are cloned, propagated asexually by cuttings or tissue culture—they have no radicle. Instead, these genetically identical plants are created to meet the needs of the horticulture industry: easy to grow (compact, fast growing, unappealing to insects), easy to ship (short and tight “muffin-tops”) and easy to sell (big, bright flowers). These cultivars are often given cutesy, easy to remember, wince-worthy names, like “Incrediball”, “Pinky Winky”, and “Miss Piggy”. Many are patented, with the “inventor” getting a royalty for every plant sold. Specialty plant propagation of this sort has become very big business, encouraging lots of people to shop and plant varieties that would seem to be great for greening up the world. But how is it working for those plants and our ecosystem? We aren’t yet sure. Ecologically sensitive gardeners, especially native plant enthusiasts, are carefully watching to see how these plant clones will behave in the landscape, serve beneficial bugs and birds, and react to threats from things like pests and disease. Time will tell.
And what about the impacts of starting life without a radicle? Vegetative (seed-free) propagation relies on adventitious roots, which originate from stem tissue (not the radicle). They are fibrous, tangled, and often found circling the bottom and sides of the container in which they were grown. Can they do the same job as root systems with a radicle, formed by the natural process of seed germination? We know that asexually propagated plants will sometimes "revert" to their original species form, or otherwise grow out of the commercially driven traits that made them desirable to begin with. This is often not a concern for the breeders since replacing failing plants is good business. But it isn’t great for creating sustainable gardens, and it’s especially not great for trees, which are all about being around for a long time. I’ve been noticing clonal nursery trees, which have nothing but adventitious roots, showing signs of suffering as they age. Their fibrous, adventitious root systems have a tendency to wrap around and choke the tree (called girdling roots), which causes trees to die back a little at a time and weaken or even snap at the base. (Learn more about it here.)
Take a look at the trees in your yard, neighborhood, and community. How many of them were grown from seed right where they were dropped by their mother tree, assisted by her mycorrhizal network? Sadly, there isn’t much opportunity for this to happen in our managed lands.
So, if you find an acorn sprouting, save it. Try to plant trees grown from seed, no matter how small. Yes, it is a slow process, but think of them as your family. Don’t we love the process of raising our families from birth? The natural process of putting down a root and letting it grow is one that has evolved naturally and successfully for every life form. It connects us to nature and makes us happy and whole.

Another Earth Day is coming up. And, yes, it can be easy to question whether all the work we are doing is enough in the face of so much bad climate and biodiversity news. There is still so much land being harmed all around us with noise and poison. Of course, it’s no surprise that we might be eco-anxious. Nevertheless, I am feeling optimistic this Earth Day…it is the 10th birthday of the launch of Perfect Earth Project and there is so much to celebrate.
For one thing, the media has really caught on to the urgency and importance of our message. Each week I see a plethora of stories about reducing lawns, leaving leaves, and planting natives for biodiversity. There are pollinator groups forming—and growing—in most communities. These groups are filled with passionate people who are learning about nature-based land care and sharing their knowledge with others. They are putting pressure on landscape professionals to learn about plants and provide nature-based services. Where garden centers fail to provide native plants, they hold native plant sales. They are posting beautiful photos of their wild front yards to help drive the aesthetic of what a good garden looks like. They are saying: We don’t have to wait for ordinances or laws to change. We can do this now, together. We can make a huge difference. And, for sure, they are making a difference.
Every single one of us can make a difference. On our own or with a group, we can build habitat (food, shelter, water) in our gardens, learn the names of native plants (especially keystone species) and the birds and insects they attract, and then plant them, at our homes and in our communities. We can let plants grow to their natural shapes and leave deadwood for the bugs and birds. We can be highly attentive to soil, and water properly as we enter a future of shortages. We can practice doing no harm.
I will remain optimistic. Because those of us who are doing this are doing something amazing. We are changing the way we relate to nature in how we relate to our land. We are CARING for the land. We are making landscapes that are full of life. We are, most of all, building resilient humans, who will face the future with nature on our side.

I like learning about things that are obvious once I know how to look for them—things that were often common knowledge in the past. In spring, birds are telling stories about where they choose to raise their young, stories based in logic, with a dash of magic. Here’s what I’ve learned:
1) Birds don’t actually live in nests.
Well, I guess it depends on your definition of live. Birds lay eggs and raise their young in nests. But once the kids have flown away, the parents either renest with a new brood that season or abandon the nest for the wild. The nests you are probably imagining right now are most likely found hidden in a dense leafy shrub or in the canopy of a tree, where they provide shelter from weather and camouflage from the sharp eyes of predators. Different birds have different nesting strategies (form, technique, and material).
A simple cup-shape is the most common nest type. You can find them in any number of places, such as along branches in the tree canopy, perched in tree forks, or nestled on ledges.
2) Not all birds make nests.
Or, rather, not our idea of a nest. Some birds can get by with just a depression in the ground called a scrape nest. Scrapes are popular nest types for terrestrial birds (birds that prefer grasslands and open habitats that lack trees), such as shorebirds or tundra species.
Other birds are cavity nesters which take advantage of holes found in place like dead tree trunks. Some line their place with coziness, but many just lay their eggs in the space as is. There are varieties of Owl that return to the same cavity for many years to raise their young, building up a “nest” from their own poop and their kids’ poop, too. When they’re not raising kids, these Owls roost on a branch near their cavity. You can sometimes spot them by finding their pellets beneath the trees.
There are also platform dwellers (Ospreys and Eagles), mound nesters (Mallard ducks), tunnel makers (Belted Kingfishers, Atlantic Puffins), pendant builders (Baltimore Orioles), and those who chose no nests at all (Chuck-will’s-widow). It all depends on what quality habitats are available where they live.
3) Most birds don’t re-use their nests.
It all comes down to capacity and energy resources. Small birds often make their nests from delicate materials that don’t weather well. While some of them will reuse their nests to raise another brood or two in the same season, they almost always build new ones the following spring. Starting from scratch reduces the possibility of ectoparasites (mites, lice, etc.), which can negatively impact the health and survival of chicks. It also helps avoid predators who know the locations of the nests from last season. Big birds, like Bald Eagles and Ospreys, who can carry large branches and twigs, will return year after year to the same nest, adding to the old one and making it larger over time—unless another bird steals it first.
4) What about Birdhouses?
For cavity nesting birds, birdhouses replace lost habitat, like standing dead trees. So the answer is yes, birdhouses are good. In fact, they have helped restore populations of Eastern Bluebird and Prothonotary Warblers. They are even better when they are cleaned out each spring to reduce the populations of mites and other pests from the previous breeding season which can harm the newborn chicks. Don’t worry about doing it wrong, the birds will only select the ones you do right.
Birds likely to use birdhouses (nesting boxes): Wrens, Bluebirds, Titmice, Chickadees, Nuthatches, and Owls.
5) What about the way YOU nest?Your garden lifestyle is intricately connected to the life of birds. Think about it from the birds’ perspective and relate it to your place.
- Leave a dead tree or two, for food (insects) and nesting opportunities.
- Plant shrubs in groups. Dense clusters of varying heights provide options and protection.
- Plant natives with lots of fruit.
- Resist the urge to prune shrubs. Instead let them grow into their original natural shapes: tall, short, dense, twiggy.
- Leave a matrix of habitats including places on the ground that you don’t mow or “tidy up.”
- Make habitat piles with fallen twigs.
- And yes! Put out some birdhouses.
6) What to Plant?
Shrubs and small trees that provide great food and nesting areas. Most of these fruits are delicious for you too, but most often than not the birds will get them first. Don’t worry about insects, birds will eat them too. In fact, caterpillars are the primary food for their young. Here are some of my favorite native trees and shrubs:
- Arrowwood viburnum (Viburnum dentatum)
- American beautyberry (Callicarpa americana)
- Chokeberries (Aronia spp)
- Eastern red cedar (Juniperus virginiana)
- Elderberry (Sambucus nigra)
- Highbush blueberry (Vaccinium corymbosum)
- American holly (Ilex opaca)
- Shad (Amelanchier canadensis)
