Native Combinations: Late Summer Glory

Pink Muhly Grass (Muhlenbergia capillaris) has seduced garden designers for the last decade.  Its haze of hot pink inflorescences set the late summer garden ablaze.   But unlike other ornamental grasses, it is a surprisingly tricky plant to design with.  Muhly Grass does not offer the same early season mass and volume that Switchgrass and Fountain Grass provide.  In fact, through most of the summer, it sits low and wiry—barely substantial enough to cover the mulch.  I planted a large mass of 120 plants beside a path in a southern garden I designed.  The result was rather disappointing.  Until August, it looked rather weedy and insubstantial.  Once it bloomed, the effect was glorious.

2011 Topic List for Speaking Engagements

I occasionally get requests for to speak to garden clubs, public agencies, or other groups.  I love nothing more than talking with other interested gardeners, designers, plant geeks, and landscape architects.  I've just added a page to this blog that list topics that I have already developed talks for.  I've attached a link to the sidebar called "Talks."

The Best Planting Tip I Ever Received

This spring my wife and I started to convert the expanse of lawn around our newly purchased ranch house into gardens.  While we focus on renovating the insides of the house, the focus for our garden is its infrastructure and bones.  To that end, we’ve been smothering several hundred square feet of lawn under cardboard, newspapers, and compost; planting young shrubs to create screens; carefully carving specimens out of overgrown trees; and generally preparing the soil for future garden spaces.  Last week we installed several hundred perennials and grasses on the side of our house.  During that planting, I remembered the best planting advice I’ve ever received.

This advice came to me by way of a representative from Monrovia Nursery.  Monrovia is one of the sleeker national nurseries with big ad budgets and relentless branding strategies.  While I’m typically turned-off by glossy national nurseries and their patented plants, I must admit that Monrovia knows their stuff when it comes to installing plants.

The advice focused on techniques of installing container plants.  The big problem with container plants is that they get root bound.  Roots naturally grow out and down (mostly out) away from the plant.  When the roots of a plant in a pot reaches the wall of a pot, it has nowhere to go and will begin circling the perimeter of a pot over and over again.  Almost any gardener who has brought home a new plant from a nursery has seen how a container plant can get root bound.  It’s best to avoid plants in this condition, but often gardeners don’t have that option.

Native Combinations: 2 for the Shade

A shade tolerant Solidago?  A few years ago, I saw a beautiful clump of Solidago flexicaulis (Zigzag Goldenrod) on the side of the road in Vermont.  It was so stunning I stopped the car and pulled out the camera (my wife loves it when I do this—our vacation pictures have more plants in them than people).  Initially, I could not identify the flower.  The plant’s broad-leaves have sharply serrated edges.  That foliage combined with the glowing-yellow racemes reminded me immediately of the ornamental perennial, Ligulara ‘The Rocket’.  Was this some kind of native Ligularia I did not know?

To Dig or Not to Dig: Are 'No-Dig' Planting Methods for Real?

One recent garden trend that is spreading with inexorable speed is the “no-dig” or “no-till” method of planting.  The basic idea is that plants are installed directly into the ground without tilling or turning over the soil.  While this method is centuries old, it challenges conventional gardening practices of tilling and breaking in the soil before one plants.

I’ve been aware of this method for a while, but have been surprised by how quickly it has become dogma, particularly within sustainable landscape circles.  When teaching a class on soil preparation, I mentioned tilling and watched as many of the students recoiled in protest.  “Isn’t tilling bad?” one student immediately asked.  I was taken aback.  ‘No-dig’ is not just an idea, but a doctrine, a creed, a badge of one’s eco-credentials. Proponents spread the message with revolutionary fervor. 

So is it time to put your tiller on Craigslist?  Let me weigh in on this complex issue and hopefully provide some clarity.  The gardening world has more than its fair share of old wives tales and superstitions.  This is particularly true with anything regarding soil.  We understand so little about what goes on in the soil, yet we dig, till, fertilize, and amend it with reckless zeal.  When it comes to soil cultivation, what’s true?

Here’s the bottom line: ‘no-dig’ is great, but not when the soil is severely compacted. 

After going through quite a bit of research, the evidence certainly favors the ‘no-dig’ approach.  Part of me really wanted to find flaws with this method; after all, breaking the soil before planting just feels so natural, so downright human.  Egyptian paintings 1200 years bc show people plowing fields.  But the evidence generally supports the wisdom of not digging.  Why? 

The New Azalea Garden at The New York Botanical Garden

This week The New York Times wrote a glowing review of the newly renovated Azalea Garden at The New York Botanical Garden.  I worked on the design for that garden while at Oehme, van Sweden and Associates. 
The assignment was one of the most complex planting projects I’ve worked on.  The New York Botanical Garden was in the process of redesigning the eleven-acre azalea gardens in house, but they hired OvS to design a complete palette of herbaceous plantings to compliment the sprawling shrub garden. 

The challenge was to provide seasonal spectacle throughout the year, not just around Mother’s Day when the garden attracts thousands of visitors.  Designing a perennial garden with year-round spectacle is hard enough; but doing it in deep shade and underneath and around 3,500 azaleas was an especially daunting task.  How do you plant around, under, and next to so many azaleas?  And how do you use perennials to blend and soften the jarring bubble-gum pinks, corals, oranges, and fuchsias of the azaleas?

RadioGarden: The Best Garden Podcast Period

If you haven't checked out Andrew Key's RadioGarden, my friend, you are missing out.  Andrew Keys wears many hats in the gardening world: designer, writer, entrepreneur, and blogger.  Andrew has made gardening hip for the iPod generation.  I had already been following his witty blog Garden Smackdown, when I saw that he was starting a radio podcast for Horticulture Magazine.

This peaked my interest.  For years, I've been searching for a GOOD garden podcast to pass the time while I do my studio work.  But it's slim pickings in the garden podcast world.  The vast majority of them are overly polite how-to's (today's episode: how to prune hydrangeas); or call in shows where every other caller wants to know what they can plant that will withstand dog pee.  Mind numbing stuff.

Grounded Design is One Year Old

Grounded Design is celebrating its one year anniversary this month.  Aren't blog years like dog years?  One blog year feels like at least seven human years.  Of course, so many of my favorite bloggers have been doing great posts for multiple years, like Susan Harris whose been blogging since 2005.  Now that's inspiring (I'm a bit of a late adopter myself . . . oooh, iPods?!).

I had meager expectations when starting this blog.  I thought I'd give my wife a break from my rants about gardens, landscapes, and planting and direct these ramblings into a blog site.  I expected only my parents and perhaps a few other friends I guilted into signing up for emails to read this.  I still remember the joy of getting my very first comment on the blog (even if it was an angry complaint from a company in the UK named Grounded Design).

The Native Debate Heats Up: Doug Tallamy Takes on The New York Times OpEd

While I try to avoid link-posting on this blog, this interview in Garden Rant with scientist Douglas Tallamy is too good to pass.  Tallamy rocked the gardening world a few years ago when he published Bringing Nature Home, a book based on scientific studies that show exotic plants support exponentially less wildlife than native plants.  Tallamy, a professor and chair of the entomology and wildlife ecology department at the University of Delaware, believes that biodiversity is an essential, non-renewable natural resource that people are forcing to extinction.

Tallamy addresses some of the backlash against native plant advocacy, addressing in particular the article in The New York Time's OpEd "Mother Nature's Melting Pot" that compares negative feelings towards exotic invasive plants to xenophobia.  The Times article likens the native plant movement to the anti-immigration movement:

Exile from the Garden

My wife and I recently bought and moved into our house.  It is a single story 1950’s rancher that does little to combat the idea that all post World War II architecture is crap.  The location is killer, and the house was incredibly priced.  After almost seven years of trying to get into the DC market, we made the plunge.  Of course, the house was incredibly priced precisely because it was so run down.  The previous owner had some issues with hoarding and an apparent aversion to maintenance.  The listing called the house “ignored not abused”—one of those euphemisms that only a realtor could spin.

Since we closed on the house in December, our lives have been absorbed by the enormity of the projects.  Every surface of every room needs to be replaced, re-covered, and re-done.   The bathrooms and kitchens must be scraped down to the studs and rebuilt.  The floors have to be refinished or replaced.  Every window, door, and heat register must be made new again.  It's not because we're perfectionists; the place was just nasty.  And because we dumped all of our savings on the down payment, we are doing the entire renovation ourselves.  Thanks to the epic kindness and patience of my father-in-law, who comes over almost every weekend to help us, we have been able to do things I never imagined doing myself.  But the scale of the project, combined with the care of a seven-month old baby, is overwhelming. 

We live in the midst of the construction.  The rituals of domesticity merge with our construction projects in confusing ways.  Our “kitchen table” is a piece of plywood set on two sawhorses.  The other day at dinner, I reached for my fork and picked up a wrench instead.   I brush my teeth and wash dishes in the same sink I clean my drywall knives and fill up the tile saw.   And I’m beginning to think of our Shop-Vac as our family pet (we call him Vacu-saurus, and he’s always at my side).

Grounded Design Joins the Garden Designer's Roundtable for 2011
