The Magnolias

galaxy-magnolia.jpgIn most every year I have written this blog, there is an essay about magnolias.  I have a big love for them.  The flowers are dramatic and showy-I so welcome a gesture of this magnitude after a long winter.  A good bloom is never a certainty.  They bloom early in my spring-which also means they bloom late in my winter.  Last year, given a string of April days in the low twenties, every bud was reduced to a gooey black rotted mess, hanging from the branches.   That hanging persisted well into the summer-a vile reminder of the capricious nature of spring weather.

blue-sky.jpgBut when the magnolias are good, they are very very good.  My neighborhood has plenty of old saucer magnolias in evidence.  Some are planted very close to the foundations of homes-they do not seem to mind this.  Many have multiple trunks that have grown to considerable size.  A saucer magnolia in full bloom is heart stoppingly beautiful.  My saucer magnolias are a hybrid of magnolia soulangiana, named Galaxy.  The day I planted the three of them in my driveway garden, they had long spindly arms-gawky, they were.  The one tree with the most sun has grown to a considerable size.

magnolias-and-maples.jpgThe second tree will catch up to tree number one in the next few years.  Tree 3 took a giant hit in the trunk from a careless truck driver in the driveway.  Late this winter I took down an old Norway maple in this area whose girdling roots have been hard at work squeezing the life out of it.  So little of the canopy was green last year-looking at it made me wince.  It was time to give up the maple, in the interest of the health of the magnolias-and a group of parrotias.

galaxy-magnolia.jpgThis cool spring made for a glorious magnolia bloom season.  I admired them up close.  I stood under their blossom laden branches.  I admired them from afar.  Why this love of magnolias?  The spectacular bloom aside, they are a very handsome tree.  The grey bark is beautiful.  The mossed bark on old trees-sensational.  The leaves are large, and glossy.  Their winter shape is strikingly architectural.  They are beautiful trees, no matter the season.  Their mature size is a size that any modest city property such as my own, could accommodate.  I have a city lot and a half, which is home to 11 magnolias-no kidding.     magnolia-butterfly.jpg

8 of my magnolias are planted in the half lot, in the front of my yard.  They are under planted with boxwood.  They are yellow magnolias-yes yellow.  Hybridized by Phil Savage, the blooms of the magnolia “Butterflies” are the most astonishingly gorgeous pale yellow imaginable. I met Phil Savage when I was young, and working for Al Goldner.  Al was a landscape designer who owned a nursery.  He loved plants-and he loved design.  I was so lucky for my exposure to him, and his work.  Al made it his business to introduce anyone designing for him to people who grew great plants.  So many years later, I treasure that experience.

magnolia-Butterflies.jpgPhil owned a large property in my area.  Though he passed away a few years ago, that property is loaded with magnolias-many of which exceed 60 feet in height.  I had occasion to see his trees in full bloom a few years ago, courtesy of a niece, who is a client.  I was astonished at what I saw.  Yellow, peach, pale pink and hot pink flowers on magnolias that towered high above the ground.  My pictures of his property are so bad-I would not publish them.  But the experience of his vision about magnolias-this I will never forget.  This is why I plant magnolias, any time I have the chance.

magnolia-butterflies.jpg

The bloom, even in a really great year, is not long.  Should you need more than that momentary experience of their shockingly beautiful flowers, consider their leaves, and their gorgeous shape.  I for one do not mind an experience of the garden that is fleeting.  Every season has  its perfect moment.  I do not need any plant, any garden, or any landscape to to do more than their season.  I do not hold the brevity of a season against any tree.  As for  Phil Savage’s property-yes.  It has been sold.  The buyer I would guess has no interest in that magnolia forest the likes of which I am sure does not exist any where else on this planet.  The new owner has another idea in mind.  I hear from friends and colleagues in the growing community that there is a plan to take cuttings.  I so pray this plan comes to be.

A plan to preserve and nurture the magnolias bred by Phil Savage-this seems a fitting essay for Mother’s Day weekend.

B Is For Boxwood

boxwood-spheres.jpgRegular readers of my essays know I have a big love for boxwood.  This fairly small and very dense growing evergreen shrub is as versatile as any plant it has been my pleasure to plant.  It is tolerant of a wide variety of soil conditions, and it is quite shade tolerant. Its natural growth is charmingly shaggy.  It is more than tolerant of pruning-that is, pruning into shapes.  Long hedges.  Curving and scrolling hedges.  Spheres, squares, rectangles, pyramids trapezoids and triangles-boxwood tolerates this too.  Boxwood hardy in my zone is also hardy in pots-provided they get proper water and drainage.  Boxwood is just about the most obliging plant material on the planet-for those gardeners that are as interested in design as they are in plants.

boxwood-topiary-spheres.jpgBoxwood flowers are tiny, and anything but showy.  The leaves are quite small and unprepossessing.  The texture the mass of leaves make-interesting and lively enough.  Not massive and sculptural, like the leaves of ligularia,  petasites, gunnera, rodgersia or alocasia.  Quietly textured.  Where boxwood shines has to do with volume, mass, and shape.  A hedge of boxwood is satisfyingly regular and pleasing-no matter whether the hedge is natural and shaggy, or closely cropped. A mass of multiple boxwood plants can create shapes of great visual interest.  That mass can be pruned flat-like a sheetcake.  That mass could be pruned on an angle, or in undulating waves.  That mass could narrow at one end, and wide at the other.  Boxwood will oblige-whether the landscape design is crispy contemporary, or unabashedly traditional.

boxwood-spheres.jpg Boxwood grown over a period of time can be shaped into specimen plants-the hallmark of which is the evidence of the pruning hand of a gardener. Pruned boxwood in traditional forms and shapes dates back centuries.  Pruned boxwood with a decidedly modern shape-equally as compelling.  Why am I so interested in the shapes, the mass, the volume and the texture of boxwood?  I am as interested in design as I am interested in plants.

boxwood-on-standard.jpgA completely natural and God given landscape-that would be the wild and untouched places in the Upper Peninsula of Michigan.  The climax forests. The primeval forests.  The roadside weed colonies.  What grows out of the tarmac, or next to the railroad tracks.  An accident of nature can be the most thrillingly beautiful sight imaginable.  Part of why people travel is to experience the natural world-untouched by people- in places all over the earth.  An undisturbed stand of birch, a field full of Queen Anne’s Lace, a bog ablaze with marsh marigolds in the spring-all gardening people love these places.

hardy-boxwood.jpgThat said, I am at heart, a designer.  I favor landscapes that make a statement from the heart, the head, and the hand.  People can be heavy handed, but they can also be kind, patient, observing, caring, daring, brilliant, and nurturing.  I am interested in the choices gardeners make.  I am also very interested in the choices designers make.  Choices gardeners make provide for astonishingly different outcomes.  Designed landscape spaces are structured.  They may be structured around use, and traffic.  They may be structured with beauty in mind.  They may be structured for a particular season, a favored color, a sense of visual balance, for mystery, for fun, for meditation.  They may be structured around a very personal and particular point of view.

triple-ball-boxwood-topiary.jpgBeautifully structured landscapes transform an idea or thought into a picture.  I would explain this idea in this way.  Many people could not draw a portrait, but every person is able to recognize the face of an acquaintance or friend.  Many people recognize the faces of people they have not seen for years, or people they only know slightly.  Visual recognition is a very powerful human attribute.  We all have it.   Designers appeal to visual recognition.  The delight that comes from visual recognition-extraordinary.  Design that manages to engage all of the senses is great design.

boxwood-topiary.jpgWe had a number of boxwood topiaries delivered a few days ago, from a grower on the West Coast.  We do not order plants over the phone, sight unseen, via an availability list.  Rob flies out there every winter.  He walks the fields.  He chooses plants that he feels beautifully represents his point of view, as a designer.  He discusses the pruning, the care.  His buying-incredibly personal.

double-trunked-boxwood-topiary.jpgAny great design bears the mark and hand of a client, empowered by the hand of a skilled designer.   I will say that the design of my landscapes is primarily about a relationship, forged.  A passionate client, and a passionate designer makes for landscapes of note.  I feel very confident saying that great landscape design springs from a relationship marked by mutual passion and respect.  I have a great respect for the boxwood topiaries that Rob chose to buy.  I feel completely confident that should I recommend to client that they invest in an old plant with a history, they will not be disappointed.  There is a provenance in which to trust.

boxwood-spheres.jpgThe intense rain this afternoon-so great for these newly relocated plants.  The new growth is glowing.  My clients who asked that I draw the locations for 100 boxwood in pots in his landscape-this post is dedicated to them.

Iseli-style-boxwood-topiary.jpgThis boxwood topiary-astonishing in its age and size.   Rob tells me it reminded him of Thomas Church.  I can see why he fell for it.  There is the sure evidence of a patient, committed, and loving hand.  We make extraordinary plants like this one available to gardeners.  But more than that, we design.

 

 

Spring Pruning

limelight-hydrangeas.jpg

The day you put a plant in the ground is the first day of a relationship.  If you plant cosmos, that relationship constitutes one season.  If you plant a tree, that relationship might survive for generations.  If you plant shrubs, you could have a good many years of pleasure ahead of you-provided you prune.  Woody shrubs, left to their own devices, go to rack and ruin.   They spend no end of effort piling on enough wood to send the tips of their branches to the sky.  What is the big attraction of the sky?  No competition for light, air, and rain. No shrub feels any inclination to bloom where you want to see blooms-at eye level, that is.  Plants grow with survival in mind.  Should you have another idea in mind, wade in.  Participate.

pruning-hydrangeas.jpg

Shrubs will grow sideways, around an obstacle.  They will sprout back, if cut to the ground.  They will survive the indignity of a homeowner with a hedge trimmer gone amok.  They will survive, even though the overall shape may be ungainly, or sheared to within an inch of its life.  The instinct to live is strong.  Lucky for me, and every other gardener who has learned on the job.  Pruning a hydrangea is not hard-it just requires the patience to consider every branch, before you cut.  I prune each branch, one at a time.

pruning-hydrangeas.jpg
A well pruned hydrangea looks like it has had a shag haircut. Every branch has its our airspace. This means some branches get last year’s flowers cut off-only. Other branches get 8″ removed. Others get 16″ removed. Some old and thick branches in the middle get cut even harder, so air and light can reach down in to as many branches as possible.  Some gardeners prune their Limelight hydrangeas to within 14″ to 24″ of the ground, forcing them to produce basal shoots which originate underground. This method tends to produce a shorter shrub, with fewer and larger flowers.  I dislike cutting this hard-it takes so long for the shrub to regain a natural and airy shape.  I would rather have lots of flowers, than a few gigantic flowers.  I would rather plant the shorter growing version of Limelight- “Little Lime” – than prune a Limelight too hard.

pruned-hydrangeas.jpg

I like my Limelight hydrangeas tall, and I like lots of flowers. My yews are 48″ tall at this end of the garden, and the arborvitae are 14′ tall.  The hydrangeas grown 6′ to 8′ tall-perfect for this spot. For good flowering from top to bottom, the lower branches need to be left long, and the top branches need to be shorter. The finished shape should be very loosely pyramidal, or like an egg on its side.  Step back frequently, to see how things are shaping up.  This hydrangea blooms on new wood, so no matter how you prune, you will get flowers.  Shearing a branch will encourage that branch to produce multiple shoots below the cut.  Thicken up, and out.  As long as the exterior shape is loosely described, the shrub will prosper.  Shearing deciduous flowering shrubs may take less time, but produces less than desirable results.  Renovating shrubs that have been sheared takes a long time.  One cut at a time-this is my advice.  Invest in a great pair of pruners-this makes the work easier.  The moment that all I can hear is the birds, and the action of the pruner blades bypassing each other, is a spring gardening moment I treasure.

pruning-roses.jpgI do grow a few shrub roses.  Sally Holmes, Carefree Beauty and Earthsong.  I have read lots of articles about pruning roses, none of which I have paid much mind to.  I stop dead heading my roses in mid-August.  I actually love the rose hips in the fall and winter.  In the spring, when the buds swell, I prune. The swelling of the buds?  You will recognize swelling buds when you see them.  My roses bloom on the new shoots.  I never cut a branch back by more than 1/3rd.  I prune the entire collection of roses as if they were a single plant.  I leave them loose. Last fall I secured the summer’s growth of the climbing roses to the wall-not much needs to be done to them now.

rose-hips.jpgOccasionally I will hard prune an old climbing rose cane low to the ground.  This keeps new growth coming from the bottom. Pruning stimulates growth.  Pruning a climbing rose cane 6 feet off the ground will result in a rash of shoots.  A long stalk with a tuft of shoots on the top-not the best look. Any cane which you can train to grow horizontally will flower more heavily.  If you think about the where the sun and rain comes from, this makes sense.  Is the afore mentioned a guide to pruning roses-not really.  Every gardener has to deal with their roses one to one.  Look at them, and decide how to prune. I prune my roses so they have the best possible overall shape.  Most roses are very ungainly growers, so pruning for a good shape is not always so easy.  That’s why I grow asparagus with my roses.  The  ferny fronds conceal those awkward and ungainly branches.  Do I prune my asparagus over the summer-oh yes.  I keep them at a height which conceals those legs.  Does this affect my asparagus crop?  Maybe.  But everything in the garden is about choices.  I want great roses more than I want home grown asparagus.

beech-ferns.jpgI do not cut back my beech ferns in the fall.  The dead fronds mulch and protect the European ginger over the winter.  By April 1st, those fronds have cut loose from the crown.  I do not need to prune.  I rake them off.  A rubber rake does a great job.  My fingers do the best job.

european-ginger.jpgThe European ginger has already been busy, sending out new shoots.  A steel rake, or a size 8 boot can damage these tender new shoots.  One of the pleasures of the spring-the new growth.  Friable soil.  My housekeeping inside-rather rude and abrupt.  I just want to get the job done.  When I am cleaning the garden in the spring, I take my time.  I do it-gently.  I have a relationship with this garden that I intend to nurture.

snow.jpg
Lifting a lower branch of a spruce, I see icy snow. The transition from winter to spring has been incredibly slow this year. Really shady spots in my garden are still frozen. The night temperatures are still below freezing.  Frozen ground, frozen branches-my advice is to let them be.

April 2 2013 (40)The hellebores are awake.  Last years foliage has collapsed in a heap on the ground.  Every day I think about cutting that old foliage away.  Clean and bare is not always the best situation.  The newly emerging flowers benefit from all that fluff. The transition from winter to spring can be a rocky journey.   Sometimes, the best thing to do is to do nothing.

hellebore-flowers.jpgLast year’s foliage protects those flowering stalks, ready to emerge.  A warm spell in March proved to be damaging.  The buds sensed it was time to grow.  Nature had a different idea in mind.  We have had a run of really cold weather, the past 3 weeks.  Some of the exposed buds on this plant are black with the rot produced by freezing temperatures.

uncovered-hellebore.jpgCutting away last years foliage  exposes new flower buds.  Very tender flower buds.  Just to look at them, you would know they are not armed against the cold.  I cut the dead leaves away, and put them back over the top of these buds.  It is too soon to clean here.  What constitutes better days?  Warmer nights.  The ground is still very cold.  It will be 2 months before the soil really warms up in my zone. Hellebores do not require warm soil, but the flowers will be damaged by night air temperatures in the mid to low 20’s.  They need all that litter on the ground over them.  It’s not time yet to wash and put away the blanket.

hellebore-seedlings.jpgI am shocked and pleased to see that I have hellebore seedlings sprouting.  I spent a few moments taking this in, before I covered them up.  I am not sure how long it will be, before I expose them to the light of the new season.  The pruning and the cleaning-all in good time.  A slow spring-this is what we have now.

Pruning Trees

March 30a 2013 (2) There are plenty of reasons to prune.  The branch of a tree, shrub, or rose may be dead, and need removal.  It may be growing across the sidewalk, and need some heading back.  An old lilac may be blooming only at the top, 15 feet above ground, and need rejuvenation.  Branches of shrubs that cross over each other, and rub off the bark is an invitation to disease or insect damage.  Intact bark protects the life inside.  Pruning can help keep woody plants vigorous, healthy, and beautiful.

linden-row.jpg
Plants maintained as hedges require regular pruning. The lindens at the shop form a hedge the body of which is above ground.  The branches at ground level have been removed over the years so people may walk underneath them.  Regular pruning of the trees promotes a good framework of branches that represent the desired shape.  These lindens were overdue.  Though I am a serviceable pruner of shrubs and roses, this job asks for an expert.  Someone who knows how to safely navigate high above the ground, and someone who understands the consequences of each cut, deliberately pruning in anticipation of a desired result.
pruning-the-lindens.jpgTrees that are trained as an overhead hedge are pruned with the idea of encouraging lateral growth.  Anyone who has ever topped a shrub knows that the plant responds to a single cut with multiple sprouting shoots.  This results in a dense pattern of twigs on top, which blocks the light to the interior.  Every branch of a plant needs light.  Shrubs that are repeatedly cut back so every branch is the same length eventually decline on the interior, and will need more drastic pruning to restore them to health from the inside out.

pruning-trees.jpg
Pruning trees in late winter means there will only be a short time before growth resumes, and the healing of the cuts can begin. Another reason to prune now is that the cuts will stimulate growth at a time of year when new growth is expected.  Trees actually stop growing and begin to go dormant in late summer.  This is part of the process by which they are eventually able to  go totally dormant, and endure the winter without injury.  I do not like to prune seriously at the end of the summer or in the fall-the plants should be going to sleep.  Not shocked into growth.  Pruning these trees the end of March will encourage dormant buds to flush out.

on-the-roof.jpgThe roof next to the trees turned out to be handy.  This perch, and a long and very sharp pole pruner, enabled Jack Richardson, owner of Guardian Tree Experts, to trim the inside flat sides of the lindens.

inside-pruning.jpg

When the trees leaf out, those leaves will make a giant rectangle above ground.  They will represent this better next year than they will this year. Pruning that waits too long means more time will be needed for the trees to grow in how you envision.  The trees were originally planted far enough away from the building so the shape would be easy to see.  This also permits light to wash that dark wall.  The relationship of the sun to the shade is a feature of this space in the summer.

pruning-trees.jpgThe big cuts make it easy to understand the concept of lateral growth.  The thick branches are pruned back to a smaller branch which is already growing in the proper plane.  The smaller branch will benefit from the growth energy in the tree directed its way.  Dormant buds at this point will emerge, and grow into the space around the larger branch.

hedging-the-lindens.jpgThe overall vertical plane has been reestablished.  In a year, a decision can be made about whether to prune again, or wait until the following year.  That said, frequent and less drastic pruning makes for a quicker recovery time.  Regular pruning from the beginning helps to create a strong and healthy structure.

dying-tree.jpgThe ultimate pruning means taking a tree down to the ground.  This maple, suffering from girdling roots and severe injury from lightning has become a hazard.  The large left lateral branch is at such a near horizontal angle that the branch has begun to split.  The original wound never really healed, and now the tree has begun to rot.  No one could foresee the exact moment that this big tree will give way, but all of the signs are there.  This tree needs to come down.

taking-down-a-maple.jpgNorway maples are especially prone to girdling roots.  A root that encircles a tree trunk can eventually grow enough to strangle the tree.  At a certain point, the pruning of the offending root is too late to make a difference.  Every one of the maples on my property had significant girdling roots when I moved there.  Knowing that this tree would eventually die, I planted other trees around it.  The loss of a large tree can be devastating to the community planted underneath it.  This maple had been in serious decline for many years.  Very little remained of its crown.

making-room.jpg
There are 5 trees that were planted fairly close to the maple-2 magnolias, and 3 parrotias. Those trees had been in ground and growing long enough for their upper branches to reach the height of the lower branches of the maple. The time was right to take the maple down. The 5 remaining trees will prosper from the light, space, and less competition for water. They should grow very fast now; their filtered shade will be just what the garden underneath them will need.  Guardian Tree Experts in Ann Arbor-they do first rate work.  The trees are ready for a little spring weather.
