Nurturing Osmosis’s Japanese Garden – Winter/Spring 2019

By Michael Alliger, Master Pruner

Here in west Sonoma County, California, 5 miles from the Pacific Ocean, March is the turning point of the seasons. In the Osmosis garden, winter work is nearly finished with the anticipation of spring’s soft explosion at hand. Though the weather varies, the seasons are consistent. Winter is marked by the loss of leaves on deciduous trees indicating the relative inactivity or dormancy of all plant material. Among the first signs of spring are the flowers of plum, which precede leaf growth.

 

Window of Opportunity

The window of opportunity for winter pruning is in this dormant period indicated by bare branches. Insect activity is also reduced at this time, lessening the chance for infestation. Winter work falls into two categories: Structural Reduction & Correction and Refinement of the winter silhouette (look).  We learn from Japanese gardens that within the garden walls trees are kept at human scale, not towering above, as is their wont. Therefore, a consistent effort to contain trees and shrubs throughout the year is ramped up in winter as dormancy allows for more aggressive pruning. 

One such situation in the Osmosis garden is the presence of a planted Monterey Cypress. Left on its own it would dominate and outgrow the limited space it is afforded. Yet for nearly 20 years we have managed to keep it at approximately 15’ with a fairly natural appearance. Normally this tree would not be a good candidate for a garden but, it was a gift and we have taken it on as an experiment to see what might be the possibilities and limitations of this native plant.

We have a large Mayten tree (broadleaf evergreen) anchoring one corner of our tea garden.  This fast-growing tree is necessarily reduced and thinned each winter. We also have two Douglas Firs (another native) which are maintained in our bath garden as large shrubs (!) at about 8’.

Osmosis has a limited number of Japanese Maples with each being planted at a primary location (path or pond) in the garden. Ranging in size from diminutive (18” x 36”) to person-sized (6’ x 5’) these trees must look excellent all through the year. This means winter pruning is required not only to set up a beautiful spring/summer look but also to treat the eye in winter to the intricate delicacy of bare branches.

Pine Trees

red pineAlong with the evergreens previously mentioned Osmosis has a number of Pines that get close attention.  We have three Red Pines and three Black Pines.  Two of the red pines are structurally pruned in winter to maintain proper scale.  All the pines are groomed of excessive needles both as a matter of appearance and to help limit spring growth by reducing photosynthesis.

Support plants such as Grasses and Tamamono (mound-shaped shrubs) are also seen to in winter.  Grasses are cut to the ground in anticipation of spring’s regeneration while the sheared shrubs may get a thorough opening up with hand pruners to allow light and air to reach inner branches that back budding may occur. Back budding is the breaking out of new leaves on bare wood. The vitality of inner wood helps ensure fullness at the time of spring shearing.

Bamboo

Thinning of Bamboo is begun in fall and may continue into winter.  Third-year culms (canes) will be dying back and are thus removed along with weak or excessively crowding culms.

Transplanting is also scheduled for winter again because of dormancy.   This year we flip-flopped Hellebores with Red Buckwheat plants that found themselves in each other’s microclimates.  We also removed a large and languishing Rosemary from our entryway and replace it with a grouping of three small Hinoki trees and an array of Manzanitas.

Advent of Spring

With the advent of spring, the gardener sharpens tools, restocks sunscreen and cinches up her belt in preparation for the marathon to come.  The surge of the plant world is both inspiring and

daunting.  With so much growth at once, the garden pruner must establish priorities.  Decisions are based upon the degree of unruliness and visual prominence.

Though Japanese Maples are amongst the most meaningful plants in the Osmosis garden their gently soft spring growth is so welcome and complacent that pruning may be set aside for more pressing matters. 

When the time comes, Maples are both thinned and reduced for proper scale and a natural look.  The one caveat is that when maples are in full sun or receive a lot of afternoon sun care should be taken to not open large holes in the canopy as inner leaves and bark can burn if suddenly exposed to strong heat/light.

Importance of Hedges and Shrubs

green dragon hedgeOne of the possibly more pressing matters mentioned above is the 30’ Green Dragon Hedge separating the meditation garden from its entry gate.  The importance of this hedge cannot be overstated as it provides the hide-and-reveal effect so integral to Japanese gardens allowing for a gradual revelation as guests follow the path.  Once grown out wild, this element becomes more of a distraction than subtle influence so it’s imperative to keep it in bounds.

At Osmosis, we use manual hedge shears rather than gas or electric powered.  The cleaner, sharper result is well worth the extra time and effort in a garden where aesthetics encourage a peaceful meditative state.

Along these lines, the individual sheared shrubs (we use variously Berberis, Euonymus, Spiraea and Germanderare sometimes overlooked in deference to the dramatic appearance of pines and maples yet their function in the garden is paramount as a grounding element and counterpoint to the focal trees.  These smaller shrubs (Tamamono) must be tended with consistent care especially with spring’s first burst.

Flowering Trees

Perhaps flowering trees such as Camellias, Rhododendrons, Ribes and Magnolia present questions as to when to prune them.  In all these cases, as with Plum, the flowers appear before the leaves.  This means that a well-maintained plant won’t need pruning (except grooming and deadheading) until after the new vegetative (leafy) growth occurs and extends.  Observation leads to pruning guidelines.

pine

Lastly, in our discussion of spring pruning is the Japanese Black Pine.  Whiles there are many approaches to pine pruning, here at Osmosis we

remove the candle growth in spring followed byselective thinning in fall and winter. Candle is the term for the initial spring shoot growing on pines. Candle growth generally signal the strength and will power of the tree as it tries to attain its genetic height (60’).  This size being beyond “human scale” in the garden, forces us to meet the tree’s will with skill and an aesthetic will of our own. As they extend, candles initially look like tubes; when they stop extending needle open out from the tubes.  It is at this time they are removed in favor of their replacements, which develop over the summer in greater numbers and lesser length.

We who garden are fortunate to be so attentive to the seasons as this draws us closer to the unseen world. Make sure you leave time to visit our gardens during your next visit to Osmosis. We also offer Horticultural Garden Tours throughout Spring and Summer for a more in depth look at the underlying Zen themes built into the rock arrangements and pond layout, as well as information about the planting themes and plant materials.

The clouds, cold and late rains seem to do what they can to stanch the onset of spring yet plums begin blooming on Valentine’s day as usual and cherries to flower by April with a host of magnolias in between. Our California natives join the fray in the form of pink-flowering currant and blue ceanothus. We meet again the urge of the world to become itself and we gardeners see to our preparations: tools are sharpened, irrigation supplies are inventoried, fertilizers applied and the weeding begins!   

Spring Pruning

magnolia at Osmosis

Spring pruning of deciduous trees like dogwood and Japanese maple usually begins around April 15th once the new leaves have come out and hardened up, that is, acclimated to sunand weather. The goal of Japanese garden pruning is to maintain an appropriate size (human scale) while instilling a look of age. This look is often a stylized version of much older trees that have been subjected to their environment’s gifts and trials: rain, snow, wind, heat, and drought. While much control and refinement is done in winter, spring follow up pruning is critical to maintaining this vision. While managing size by cutting back ends is paramount, inner foliage is thinned showing the intricacies of branching and the interplay of light and shadow.

Sheared Plants

pruning at OsmosisSheared plants are a staple in a Japanese style garden and proper shearing is an art. Along with stone, they are a fundamental grounding element bringing stasis amidst change.  While sometimes overlooked, low sheared plants, called tamamono (horizontal oval in shape) can be many. The hard-edged contour is an integral counterpoint to the more natural forms of other trees and shrubs. In Japan, azaleas largely fill this need. Here at Osmosis, for ecological reasons, we use replacements such as escallonia compacta,  dwarf berberis and euonymus microphylla. Once new growth emerges they look shaggy, blurring the crisp edge so important to their function.  Consequently, a round of shearing is necessary in spring addressing some individuals 2 or 3 times as needed.

Of all plants in our garden pines are the one group allowed to look somewhat unruly in spring.  Their new shoots emerge from buds beginning in

pruning at Osmosis

February and elongate into a tubular shape known as candles.  Though there are many approaches to pine pruning, at Osmosis we allow the candles to extend fully until needles unfold from them.  At this time they are removed (cut or snapped off by hand).  This technique controls size while the subsequent summer growth is used to develop foliage density and limited incremental extension.

The balance of plants such as nandina, pieris, flowering quince and juniper are pruned as their new growth arises.  These complementary shrubs are pruned in a more general way to add context and a natural feel to the garden.

Spring work can be busy here at Osmosis as in most gardens but the softening weather and vibrant life bring joy to every day!

Autumn 2017

With the softening of the light and cooling of temperatures comes a time for an out-breath in the garden. Autumn at Osmosis brings a relaxing sigh after the hurried intensity of summer. In the calm expanse of golden light, we look back to what has been: the surprises, accomplishments, and challenges; and we look ahead to the opportunities that winter rains will offer.

Here at Osmosis Day Spa Sanctuary in Sonoma County, California, Spring was enlivened by deep and late rains. Trees especially came out with a robust vigor. This was an expectation gratefully rewarded. The surprise was that this vigor did not translate into increased health throughout a very hot summer. Many trees seemed inexplicably weaker as the season progressed. Autumn, therefore, brings welcome relief for the garden as well as the gardeners.

Falling Leaves

Bamboo’s Falling Leaves

Though plant growth has slowed, the rain of falling leaves keeps gardeners busy raking. Raking of the paths and grounds is expected but benches, lanterns, stones and the plants themselves must be kept as pristine as possible. It’s interesting to observe that broadleaf evergreen trees (such as bays), as well as conifers, are losing countless leaves at this time. Bamboo, an evergreen, is dropping leaves at a surprising rate. For good hygiene and appearance groves must be raked and mulched. Pines, redwoods, and hinokis all display an inner browning of foliage that may drop eventually with winter storms if not cleaned by garden staff.

Lack of Rain

Anticipation of winter may stir in us the realization of how long the garden has gone without rain. Lack of rain combined with extremely low atmospheric humidity makes this the driest time of the year for plants. It’s important that irrigation be regularly monitored for accurate operation and that container plants be watered assiduously sometimes being dunked in large tubs or troughs where possible. Again in anticipation of winter rains the garden is freshly mulched with nutrient rich amendment. When percolated in by rain a mulch of composted humus and manure not only enriches to plant growth but helps keep the soil alive with microbes, insects and all manner of healthful fungi.

Fall Pruning

Fall Pruning of Evergreens

Fall Pruning

Garden pruning in the fall hasn’t the pace of summer yet opportunities for care and improvement abound. In Japanese-inspired gardens like Osmosis, many trees are pruned for human scale. This reduction often stimulates a reaction growth which must be addressed. As this growth slows in summer water sprouts on plum, crabapple and persimmon, for example, can be removed or cut back. On Magnolia, heavy summer growth is also removed in preparation for early winter flowering. In addition, fruit tress such as pear, apple and apricot may be thinned and cut back. At Osmosis, we have a large naturalized apple tree growing along the bank of Salmon Creek which is pruned as an ornamental, not to interfere with a vigorous fruit production.

Evergreens are also pruned at this time. Pines are thinned, shaped and cleaned of old needles. The same can be done with various Chamaecyparis.

Nandina

Nandina

The thinning of bamboo groves not only improves appearance by removing dead, dying, and spindly culms but also can help (along with fertilizing) to increase the size of next year’s shoots for added drama. Similarly, drifts of Nandina may be thinned to display their vertical canes from which they get their common name “sacred bamboo”, though not a true bamboo.

Yes, in gardening there is the Zen moment of NOW, but we are also keeping an eye on what has been and what will be. Winter will bring an ideal opportunity for planting and transplanting. Autumn is the time to be looking ahead to the possibility of these, often dramatic, adjustments.
