The Center Of Interest: A Short Story

red-twig-dogwood.jpgOne way to organize a creative winter garden expression is to decide on a center of interest, and design every other element to celebrate that one big idea.  If you have a mind that your winter pot needs a centerpiece, I have some suggestions about the construction.  Let’s assume that you have built a foam form, and stick all of your greens to your satisfaction.  That foam form should have a hole in the middle, close to the diameter of the centerpiece you have in mind.  Sometimes we make that hole smaller, and cut the actual size during the installation.  A tight fit is a good idea.  We arrange the centerpiece using thick rubber bands to contain every stem.  Rubber bands will oblige, should you decide to add several more stems.  The centerpiece needs a place to be.  A great centerpiece for a winter pot needs some thought about the materials, and the construction.

winter-container.jpgFresh cut twigs are woody, and incredibly strong.  But once they have been cut away from the roots of the plant, they have no plan in place to keep them perfectly vertical in the container.  The center of all of our centerpieces is a stout bamboo stake.  Having done countless winter containers, we have an instinct about how long that stake should be.  Though it is part of the above grade centerpiece assembly, that stake will be pounded down into the soil of the container when it is installed.  The centerpiece needs to have something below ground to keep it vertical.  Bamboo ballast.

winter-container-arrangement.jpgOnce the soil in a pot freezes firmly around that bamboo stake, no winter storm can dislodge that centerpiece.  There are occasions when we add another element or two to the vertical centerpiece.  Some materials get strapped onto the twigs with zip ties or concrete wire.  Some materials are stuck into the foam-in that space between the greens and the twig centerpiece.  There are those times when the overall shape of the container will ask for hand sticking during an installation.  As much as I mean this essay to be of a tutorial sort, there are no formulas.  Given a general guideline, the individual eye and hand has to drive the bus.

winter-container-centerpiece.jpgThe green preserved leptospermum in this centerpiece was wedged into the copper curly willow, and purple preserved eucalyptus.  A third element introduced into a centerpiece can stitch a look together.  This lepto is a great contrast to the sleek and thick willow stems.  The color and texture adds interest to the purple eucalyptus.  The lepto moves this arrangement to another level.

winter-container.jpgA center of interest in a winter container sets the tone.  Said centerpiece will rule the roost.  Loose and asymmetrical centerpieces read like a well worn pair of jeans.  Structured centerpieces that reach for the sky-awesome.  A winter container with no centerpiece -a winter container well on its way to a contemporary expression.  Twigs arranged to represent in the vertical dimension-more formal. Or maybe more contemporary.  A twig centerpiece that fans out-a uniform fan is very formal.  Restrained.  A loose fan breathes, and chats up a storm.

winter-centerpiece.jpgNo matter what elements you plan to include in your centerpiece, a strong construction will reward you the entire season long.  Strong in, strong out.  Invest in some zip ties, if concrete wire and pliers are not your style.

winter-centerpiece.jpgEvery move you make in the construction of a winter container has visual meaning.  What you construct behind the scenes-I am in favor of a very strong construction.  What you construct behind the scenes also makes a visual statement.  Be clear about what you wish to say.  The time and pleasure that you take to express your idea of winter-everyone will appreciate that.

Sticking It: A Foam Story

dry-floral-foam.jpgOur late fall weather took a nose dive a few days ago.  Just yesterday, it was 15 degrees when I came into work.  Bitter cold like that over a period of time can make any soil left in a container turn rock hard.  I have had gardeners in, wondering how they will get their winter containers done.  We do not stick any of our greens into the soil in a pot.  Evergreen boughs installed in the soil have only one direction possible-that is straight up.  We build forms from florist’s foam that fit tight into the pot.  The foam will stand above the rim of the pot, enabling the placement of greens to the side, and on an angle.  Once a form is built, you can reuse it, or patch it.  But another great feature of working in foam is the fact that frozen soil is not a problem.

dry-floral-foam.jpgI try to remember to take 4 ” or so of soil out of the pot when doing the fall cleanup.  The bottom layer of the foam will sit down into the pot.  The top layer gets the evergreen stems. Very large pots may ask for more layers of foam.  Given very large pots, or very tall centerpieces, we may wrap the foam with steel wire.

hot-glue-gun.jpg

We glue our layers of foam together with hot melt glue. Since the glue cools and sets up fairly quickly, we usually have 2 glue guns going at once.  If this sounds like way to much work, we make forms to order all the time.

layers-of-foam.jpgThere are plenty of variations on this theme. A long window box may ask for 3 forms that can be wedged together upon installation.  Odd shaped containers may ask for foam bricks that can be glued up, rather than sheets.  Some forms are thicker at the back than the front, if the materials at the back will be heavier in the back.  This material enables the actual sticking of the greens to be done indoors.  I would dread having to insert branches into half frozen soil when the temperature is much below freezing.  This would make the job miserable.

gluing-the-layers.jpgGardeners are routinely victimized by the weather, but in this particular instance, there is no need.  Being comfortable means the ability to concentrate on the task at hand, rather than the wind chill.  Should you want to move a branch over or up an inch, that adjustment is easy.  You can control the angle and direction of the placement with ease.  If you make a move you don’t like, you can try a different move.

winter-window-box-under-construction.jpgMuch better this mess on the garage floor, than on the front porch.  This is easy to sweep up.

dry-floral-foam.jpgThis is the third year for this form.  We actually don’t make so many holes in the foam.  We sharpen the woody stems of the greens with pruners.  This makes for a tight fit.  We look at the green topside of a branch to decide on the placement of the next.  We do not place the woody stems close together.  This helps to conserve material without sacrificing a lush look.

winter-window-box.jpgTransporting an arrangement this large takes some doing.  And the heaviest stems or centerpieces are put in once the foam is in place.  Once you get the hang of sticking the foam, there will be no stopping you.

If you haven’t done your winter containers yet, don’t despair. A little simple technology can help make it happen.  I did post lots of pictures of winter pots on the Detroit Garden Works facebook page today, should you be interested.

evergreen-boughs.jpgI would guess that I prune the evergreens in my yard back 6 inches in the spring.  A long and wild stem on a yew, I may prune back 16 inches. Do I prune in November?  Never.  But there are those farmers out there that grow evergreens with the idea to cut for the holiday season. Long trimmings grace no end of winter pots and garlands.   Our premium greens come 25 pounds to a case.  Each bough averages 18 inches in length.  We appreciate an emphasis on long and green for our  winter and holiday projects.  Greens of lesser quality are more about the woody trimmings, than the greens.

Florists greens are really short.  A centerpiece on a table needs much less in the way of length and volume than a winter container.  My advice- go for the long boughs.  I am appreciative of how many materials are available to me.  Any creative expression friendly to the garden begins and ends with what nature provides.   The evergreen boughs that will bring your holiday to life are brought to you by the farming community.  Do what you can to support them.

All Mixed Up

mixed-greens.jpg

Gardeners routinely mix plants and design elements up in the landscape.  They favor this soil mix over that one.  They mix all kinds of fertilizer from manure tea to fish emulsion.  Hybrid plants suggest a mix of that gene pool with another.  A mixer suggests a party attended by people from very different points of view.  This guarantees that a mixer will be lively and entertaining.  Mixed reviews on a film suggests there are ups and downs-will you take a chance, and go watch it for yourself?  A mix can suggest a special brew, an individual take on a theme.  A mix of perennials in a garden can help keep that garden interesting throughout the season.

evergreen-boughs.jpg

A mix of evergreen trees on the lot line is less formal, more natural, than a mass planting of a single species.  A mix of bird seed will attract more than one species of bird to your feeder.  The process of mixing up a scheme is a creative process.  Mixing colors results in a visual display that has depth.  Mixing a plant with big texture with another plant of a smaller texture can be striking. Adding another or an unexpected element to the mix-glorious.

setting-the-centerpiece.jpg

Oil and water do not mix without enormous effort.  A color mix from opposing sides of the color wheel can catch the eye.  Side by side color mixes are harmonious.  Certain mixes are bound to produce conflict.  Thus the art of a seating arrangement at a dinner party or wedding.  It is astonishing to think that every color imaginable comes from a mix of the three primary colors.  Primary colors mixed together may make for mud.  Colors mixed together in other proportions can produce colors of astonishing beauty.

Mix a violin with a voice-revel in the result.  Mix a black eyed Susan with a liatris-glaring this.   Mix a Sum and Substance hosta with Russian sage-this is horticultural discord for all to see.  Creating a successful mix of anything is an art.   By this I mean that no college offers courses in how to mix one material with another.  Were I to follow a recipe for a cake to the letter, it still might look and taste bad.

winter-arrangement.jpg

For certain clients, we elect to fill their pots with mixed greens.  The airy and contrasting textures seem appropriate, for whatever reason.  A mix of evergreen boughs can produce lots of volume  But just like imagining a mix of greens in the landscape, mixing greens in a winter container takes great skill.  The mix involves cuttings from evergreen shrubs  that have very different growth habits.  How to make those cuttings work together to form a strong and cohesive statement-beyond me.  My landscape crews have a hand.  What do I mean by this?  They have so many years behind them-planting.  They have a feel for the natural shape of a bough, and they know how to work with it.  Even more amazing is their ability to make evergreens of all types work together in a container arrangement.

red-twig-dogwood.jpg

No natural evergreen in the landscape has a mix of different types of branches, unless it is a grafted form from the Jean Iseli Nursery.  Each evergreen has an identity all its own.  Mixing the cut branches to harmonious effect, and a beautiful overall shape, is not so easy.

mixed-greens.jpgMost cut evergreens have a signature swoop.  White pine and incense have very flexible stems.  This means they can be flattened by a snow storm.  We either support the weak stemmed evergreens with a neighbor that has a stiff and stout habit, or we stick the branch so they curve up.  Gravity will have its say soon enough.  Fresh branches have plenty of spring, but as they dry, they will droop. If you are a fan of weeping branches, then perhaps this is the route to take.

window-box-for-winter.jpgIf your idea of celebratory is more along the lines of upswept, then stick arrange your branches so they all appear to curve up towards the sky.  Before I hang a mixed evergreen garland, I cut in in half, and rotate one side, and reattach it.  I hang the garland so the branches face up.  As the branches succumb to gravity, the garland looks full. Garlands hung with the branches down look skimpy .  Garlands hung with the branches facing up on one side, and facing down on the other will always look lopsided.

cut-evergreen-branches.jpgSticking greens both up and down can be a lively choice.  These pots are in a very protected location, meaning they will be shielded from bad winter weather. It takes a good eye and a better hand to spot how much liveliness is just enough, and not visually confusing and chaotic.  But do not be discouraged in any way.  It takes lots of practice to get good at anything.  I have no idea how many winter and holiday arrangements we have done in the past 20 years, but a lot is a reasonable number.

mixed-greens.jpg There’s plenty of satisfaction to be had from learning how to do.
