Verbena Bonariensis – Verbena on a Stick

September 4, 2016

Verbena Bonariensis is tall and airy and one of my fave flowers.

It blooms like crazy all summer into fall. I plant it next to walls and fences for a stunning effect. Here I mixed it with white cosmos – purple and white is such a great garden combination.

The lavender clusters are held high on wiry stems that wave in the breeze from mid summer to frost.

Called “verbena on a stick”, it is a hummingbird magnet and is an easy flower to grow.

It prefers full sun in well-drained soil. Remove top 1/4 of plant periodically to force new buds.

The Sky and Earth – a Union We Overlook at Our Peril

September 3, 2016

I often write about creating beautiful outdoor environments to lift our spirits and enhance our wellbeing but we cannot be comfortable if the health of our planet is deteriorating.

We talk about restoring balance to the earth. This starts with the soil. Once the soil is revitalized the atmosphere and weather will correct itself.

Here is why: the sky and earth interact.

In other words, droughts come from poor soils, pollution and other inharmonious activities on the ground. Fix the soil and the droughts and storms will subside.

So start with fertilizing the soil – this does not mean applying more soluble nitrogen fertilizers loaded with anhydrous ammonia or nitrates. Doing this to plants is like feeding them amphetamines. Reliance on poisons to grow our food is one of our major problems right now.

Changing this practice will help our atmosphere greatly. But it is not a quick process so we better start now.

At this point you may be skeptical but think of it this way- ammonium and urea-based fertilizers that we use to grow our food crops are susceptible to loss as ammonia (NH3 ) gas, especially when left on the soil surface. Ammonia gas from fertilizer has a negative effect on air quality and human health. Where are many of our crops grown? In the San Joaquin valley of California. Here is a photo of atmospheric NH3 over the San Joaquin Valley in 2008 (measured by the IASI satellite). It shows the most concentrated area of NH3 in the air in red. That was many years ago…guess what happened to California since then?

Healthy soil is a teeming world that contains a symbiosis of fungi, minerals, organisms and more. Root structures interact with these ingredients to elevate levels of certain nutrients. It is an interacting and amazing network.

For example, legumes such as beans, alfalfa and peas bring oxygen to the root tips and release oxalic acid. They affect lime levels, nitrogen and more in the soil (cation exchange, etc. its complicated). Legume’s beneficial activity is augmented in the presence of certain crop roots that exude carbohydrates, like corn or sugar cane.

legume-roots

You can see this in full force in the Four sisters method of crop planting used by the Native Americans: corn, beans, squash and sunflower.

  • The corn is deep rooted, mining the soil for minerals and exuding carbs to the soil,
  • Beans ‘fix’ nitrogen and elevate the lime
  • Squash covers the soil to prevent weeds,
  • The sunflower’s stems, leaves and pollen contain phosphorus, potassium, calcium and magnesium. They can be composted in the soil to help keep it nourished.
  • Buy from Renees Garden

    Add to this, composts, compost tea, rock dusts or pulverized quartz and seaweed or kelp and the soil will start to sing.

    This is vastly different from using soluble fertilizer that releases harmful gas to the sky –

    we should be building a matrix in the soil that is alive and healthy.

    So Governor Brown, please address the state of agriculture in California asap

    and the skies will rain upon the earth once again.

A Great True story about Organic Soil

August 18, 2016
Tony Avent runs the wonderful Plant Delights Nursery - offering a diverse collection of plants and the catalog is a collectors' item

Tony Avent runs the wonderful Plant Delights Nursery – offering a diverse collection of plants and the catalog is a collectors’ item

On April 29, 2010 Anne Raver of the New York Times asked: “How does Tony Avent, the horticultural mythbuster, grow so many plants successfully in his garden?

Rule No. 1: he uses the same mix of 40 percent native soil, dug on his own land, and 60 percent compost for every plant.

logo”The soil for every plant we have is prepared exactly the same, whether it’s a pitcher plant or an agave,” ….

After he switched to organics, he said, ”it took about a year before everything started jumping. Our insect problems disappeared. It was just amazing.” ….”

This observation took me back to 1972 when I was a landscape architecture student at the University of Hawaii and minoring in tropical agriculture

The university farm was in Pearl City ( next to Pearl Harbor) and it was divided into one large section devoted to standard agriculture (agribusiness majors) plots and a very small section reluctantly relegated to organic gardens (run by us ‘hippie haoles’ who were studying tropical agriculture)…

I had come to Hawaii via Kenya and was very interested in saving the world through tropical organic gardening.

This is me in Pearl City, Hawaii tending to my vegetable garden years ago – note the Kenyan Kikoy I was wearing..the latest in fashionable gardening clothes.. .:-)

The agriculture students got stipends for their seeds, fertilizer and pesticides…

the organic students got nothing….and you know what happened?

banner_ctahr
Well, every semester the organic plots got better and better because the soil was being improved consistently with fish emulsion and compost ( a local health services organization was training mentally disabled students on how to make compost on premises)

while every semester the big fertilized plots run by the aggies got worse and worse…this was back when ‘organic’ was some weird, unrealistic approach to agriculture….and no professor back then would acknowledge what was pretty evident to the eyes. The crops treated with herbicides and chemical fertilizers were poor and weak….

Of course, it didn’t help when the campus newspaper did a cover story on our ‘new organic plots’ at Pearl City..and they interviewed me.

I talked about how our crops were flourishing and about a new (ha!) organic pest control called BT -bacillus thuringensis. After that interview, I presented a report to a Hawaii legislature committee on why Oahu should use their sewage sludge in a soil fertilizer similar to Milwaukee’s Milorganite ….

they didn’t go for it but look at what is out there today:

menehune magic

Now, almost 40 years later, I marvel at how long it took society to understand what we – the hippies – knew: Organic is the only way…it is Nature’s Way.

And look at what they offer at Pearl City today:

Cottage Garden Primer

July 30, 2016

I once worked with a lovely client ( now a dear friend!) who wanted a cottage-style flower garden.

Now there are cottage gardens and then there are cottage gardens…know what I mean?

In Great Britain, it seems everyone has the most magnificent flower garden, each more spectacular than the next…

their lushness sets a standard of perfection for cottage gardens that makes me want to say to someone here in the Northeast U.S., ‘Would you like to consider an ornamental grass garden instead?”

But of course, the call of a cottage garden, filled with a profusion of flowers and smelling of roses, peonies and lilacs, makes one dizzy with anticipation.

All you need in my part of the world is a deer fence, deep fertile soil, constant watering and someone to tend it lovingly… a tall order indeed.

But it can be done. And that is what we did – installed a deer fence, brought in great topsoil and carefully amended it and added irrigation. My client followed through and tended it with a loving hand and added wonderful flowers whenever she saw the need.

The result? A sumptuous garden filled with a riot of colors, lurid with intoxicating scents.

I planned the garden to be a 10 foot wide curved plant bed bordering a level lawn. The only problem – there was no level lawn.

The rear property sloped steeply downhill and in order to make it level I needed to bring in soil and retain it with a wall. This is a big proposition in any situation but here it was especially dicey because I didn’t want to disturb the roots of the native hemlock trees growing near where the wall was to be located.

To accomplish this, I used the stacking, concrete units that are part of a wall system called Alpenstein. This is a great solution because no footings are required and Alpenstein allows you to plant within each unit!

It is a versatile, plantable wall system. Once planted with vines and spreading groundcovers, an Alpenstein wall blends with the natural setting.

After the site was perfect, I set about planting perennial and annual flowers. Perennials come back every year and form the backbone of the cottage garden. For that I set out large drifts or groups of medium tall, durable flowers in the mid-zone of the bed to add height and variety.

These included ‘Sunny Border Blue’ Speedwell (Veronica ‘Sunny Border Blue’), the PPA Plant of the Year 1993, and ‘Caesar’s Brother’ Siberian Iris (Iris sibirica ‘Caesar’s Brother’), a reliable and graceful flower with pansy blue coloring….

Additionally, I planted the graceful Maiden Grass (Miscanthus sinensis gracillimus) and other ‘foolproof” perennials like dwarf Gayfeather, (Liatris spicata ‘Kobold’), the tall ‘Magnus’ Coneflower (Echinacea purpurea ‘Magnus’).

Below is the list of the dependable flower varieities I used for this garden. No unusual cultivars here – just a cottage garden full of faithful staples that work together in cozy harmony..

Loren Eiseley’s Prescriptive for Our Times

July 17, 2016

“Let it be admitted that the world’s problems are many and wearing, and that the whirlpool runs fast.
If we are to build a stable cultural structure above that which threatens to engulf us by changing our lives more rapidly than we can adjust our habits, it will only be by flinging over the torrent a structure as taut and flexible as a spider’s web, a human society deeply self-conscious and undeceived by the waters that race beneath it, a society more literate, more appreciative of human worth than any society that has previously existed.

children at play outdoors
That is the sole prescription, not for survival — which is meaningless — but for a society worthy to survive.”

“Learning the Trees” – Howard Nemerov

July 8, 2016

I used to teach Tree Identification at a community college decades ago.
 
 I also wrote the book, ‘Ortho’s’s All About Trees’ which introduces trees to the reader. 
 
This poem reveals the beginner mind.   Watch for samaras and drupes…. 
 
Jan Johnsen

Learning the Trees

BY HOWARD NEMEROV
Before you can learn the trees, you have to learn
The language of the trees. That’s done indoors,
Out of a book, which now you think of it
Is one of the transformations of a tree.

The words themselves are a delight to learn,
You might be in a foreign land of terms
Like samara, capsule, drupe, legume and pome,
Where bark is papery, plated, warty or smooth.

But best of all are the words that shape the leaves—
Orbicular, cordate, cleft and reniform—
And their venation—palmate and parallel—
And tips—acute, truncate, auriculate.

Sufficiently provided, you may now
Go forth to the forests and the shady streets
To see how the chaos of experience
Answers to catalogue and category.

Confusedly. The leaves of a single tree
May differ among themselves more than they do
From other species, so you have to find,
All blandly says the book, “an average leaf.”

Example, the catalpa in the book
Sprays out its leaves in whorls of three
Around the stem; the one in front of you
But rarely does, or somewhat, or almost;

Maybe it’s not catalpa? Dreadful doubt.
It may be weeks before you see an elm
Fanlike in form, a spruce that pyramids,
A sweetgum spiring up in steeple shape.

Still, pedetemtim as Lucretius says,
Little by little, you do start to learn;
And learn as well, maybe, what language does
And how it does it, cutting across the world

Not always at the joints, competing with
Experience while cooperating with
Experience, and keeping an obstinate
Intransigence, uncanny, of its own.

Think finally about the secret will
Pretending obedience to Nature, but
Invidiously distinguishing everywhere,
Dividing up the world to conquer it,

And think also how funny knowledge is:
You may succeed in learning many trees
And calling off their names as you go by,
But their comprehensive silence stays the same.

Beautify Your Vegetable Garden with These Ideas…..

July 1, 2016

The French have long understood that vegetable gardens can be places of beauty. They located their traditional potagers, or kitchen gardens, outside their kitchen windows and included vertical structures, flowers, and artistic plant groupings designed for aesthetic appeal.

Flowers look beautiful and attract the all important pollinators to your garden. Read the wonderful article I have linked here for learning how to include beautiful flowers and more in your veggie garden.
