What to do with your scorched plants?

Pines

In the case of your pine shrubs, as you can see by this one that faces the southwest, it’s extremely scorched. This top layer of burnt needles is still protecting the branches underneath and they are not dead branches.

You can check for dead branches by scraping the stem. If brown, then it’s dead and go ahead and cut off. If it’s green, then wait until the fall to trim back.

Watering Plants During a Heatwave

Watering Plants During a Heatwave

Watering Your Plants During a Heatwave

Watering is tricky during a heat wave – or more specifically, getting the water into the plant. This largely depends on the ability of your soil to hold water. Clay, loamy, or sandy soils will all perform differently.

Soil must hold water to attract more water, as water molecules bind to each other. So if your soil is completely or almost dry, a large amount of water will run off before it accumulates in the roots.

You also have high evaporation rate during a heat wave, so the less that’s in the air (no sprinklers), the better. Water in the early morning, before the sun and heat ramp up. Watering in the early morning instead of the evening also allows time for foliage to dry, reduces loss to evaporation, and reduces the chance of fungal infections (but if heat stress is apparent midday, water again at night.

The best way to water plants is with a watering can

Controlling irrigation is essential during a heat wave, as large amounts of water can be lost to evaporation and runoff. The most controlled way to water, outside of drip irrigation, is with a watering can.

Pour a small amount of water around the root zone. Most of it will run off if the surface soil is dry. Wait about 10 minutes and pour a small amount of water again. Less should run off this time. Wait another 15 minutes, and then water sufficiently to make the soil wet to a depth the length of your index finger. This actually isn’t as hard as it sounds, because by the time you get to the last plant, it will be time to start again with the 1st plant.

If you have a large garden, this, of course, would be an all-day task. You can adapt this method to watering with a hose, but concentrate on the root zones, not overhead watering.

With container plants, heat shrinks the potting soil and leaves a gap between the hot container wall and the roots. The most efficient way to water plants in containers during a heat wave is from the bottom-up. Sit the container in something like a big plastic bin. Pour water into the bin and watch as the plant roots make the water slowly disappear. Also put your container plants in the shade.

And never ever, ever fertilize plants during a heat wave. First, a lack of nutrients isn’t the problem. Second, the plants can’t take it up, so the fertilizer either runs off or collects in the soil, which may burn the plant when it resumes its normal functions.

 

A Lesson on Pine Trees

A Lesson on Pine Trees

A Lesson on Pines

As a pine tree ages, interior and low branches die off from lack of light and energy. To keep a pine tree healthy, spring candling, winter needling, and cutting out branches to retain its shape are necessary.

Before pruning, you first study the natural shape of the tree. This may conflict with your desired shape. Strive to bring out the best potential for its natural beauty according to its natural shape. (See Figure 1)

Start in the winter by removing needles. Removing needles can reveal the graceful limbs and trunk of the tree, allow light and air to penetrate the center of the tree and lower branches, and help reveal its natural shape. (You can do this now too, but winter is the best time of year.)

After you’ve determined its shape, (and your desired shape), the way to achieve this is by pruning or “candling”. Candles are new growth on a pine. They develop from fall through winter until spring. To learn how to candle refer to Figure 2 and watch the How-To video. Candling is done in May and early June.

PURPOSE OF CANDLING
1. Control the length the branches
2. Make a greater number of branches
3. Make branches more dense

Through proper pruning, you can direct the energy flow and achieve your goal for shape, density, and form. You can direct where new development is likely to take place and create optimum opportunities for future growth.

Sakura in Japanese Culture

Sakura in Japanese Culture

Sakura in Japanese Culture

By Mary Dickson

They blossom, and then
We gaze, and then the blooms
Scatter, and then…
(Onitsura, poet)

Beyond the beauty of sakura, the national flower of Japan, lies deep symbolism for the nation and its people.
One of my Japanese friends said, about the importance of the annual blooming of cherry trees, “the shortness of life means a lot in Japan. Everything is constantly changing is a major tenet of Buddhism. If you walk under the cherry trees with blossoms, you see the petals falling down one after another. I can’t explain the feeling very well, but every time I walk under the cherry trees, I feel strongly that I need to memorize the beautiful scenery into my eyes…it only comes once a year, and I may be a little different next year because I hope I grow as a human every year.”

For many centuries in Japanese culture, sakura has symbolized beauty and mortality. Samurai warriors personified this metaphor. Bushido, (the way of the warrior), is the strict moral code of respect, honor and discipline by which samurai lived and died.

While the short life of the sakura may represent death, the blooms of spring also bring renewal, and sakura also symbolizes rebirth, the cycle of life. For over 1,000 years, the ritual of hanami has been celebrated with picnics under the gorgeous pink blossoms. Nighttime viewing, called yozakura, is popular, especially among couples looking for a romantic atmosphere.

Since sakura blooms signal beginnings, school terms start in April in Japan. The Cherry Blossom Festival in Washington, DC, takes place around the Tidal Basin. Thousands of cherry trees, sent from Japan at the beginning of the twentieth century, enthrall visitors.

Enjoy the cherry trees in the Gresham Japanese Garden, the Portland Japanese Garden, and along the Willamette River in Portland to find hope and renewal this spring.

Under cherry-flowers,
None are utter strangers.
Koyayashi Issa, poet 1763-1828

What’s wrong with this tree?

What’s wrong with this tree?

When you walk through Main City Park past Tsuru Island towards the entrance to Springwater Trail, is where Gresham Japanese Garden’s Resource Center is located. Now that you’re oriented, in front of the Resource sits this tree. It’s a 25-year old Shishigashira Japanese Maple. Its a beautiful tree—if only it didn’t have sun scald!

What is sun scald?

Sun scald is a freezing condition most frequently caused by reflected light off the snow during winter months. The damage in this case will appear as sunken or dead bark on the trunk of the tree, then later in the tree’s life the bark might fall away revealing dead tissue in the tree’s cambium layer. This damage will typically be found on the south west facing side of the tree’s trunk. It can be found on other sides of the tree if there is light reflection from other sources, like man-made structures or reflective rock faces. After a tree is afflicted by sun scald it becomes much more vulnerable to decay organisms. The plant will create walls around the affected area, but sometimes it is not enough to block the infections. The leaves of the tree are also affected by sun scald, particularly on a bright sunny day following a period of warm cloudy humidity. The damage to the leaves will start as bronzing of the epidermis between the veins of the leaf, and if the sunny conditions persist the tissue of the leaf will die.

What do we do now?

In the case of our Shishigashira Japanese Maple, we placed the sun scald side of the tree towards the west sun to promote growth because the sun scald damaged the branches causing the tree to be lopsided. After two years of deliberate, aesthetic pruning the tree shows very little sign of sprouting new branches on the weak damaged side. So, what do we do now with our Shishigashira Japanese Maple? We rotate to the good side!

The good side

Every tree, shrub landscape has a good side. The good side is referred to as the angle the the said material is most viewed. We will rotate the tree potted in the large clay pot so everyone can enjoy the true beauty of this tree.

Local Roots

If you didn’t know, Don Schmidt Nursery in Boring, Oregon specializes in growing maple trees! Our Shishigashira Japanese Maple originated from a with a Gresham-Ebetsu Sister City Association member, who propagated it from cuttings, gifted to a relative in Portland, and then donated to the Gresham Japanese Garden when the owners downsized. Such history in trees!

Pollinators: Nature’s Gardeners

Pollinators: Nature’s Gardeners

As children, we’ve been fascinated by birds, bees, and flowers, knowing little about their interrelation in nature. But as we mature, our fascination evolves into deep admiration and respect for the complex yet beautiful part they take in pollination. Whether it’s the honest surprise of seeing a lone butterfly in the garden or intentionally attracting birds, pollinators are nature’s intuitive gardeners, and we are bystanders as they work wonders among other plant life.

Who Are The Pollinators

Nature has its own intuitive way of maintaining the ecological process of pollination through its agents. And although animals, humans, and even wind can be pollinators, insects and birds perform a bulk of pollination.

Hummingbirds And Their Wings

Hummingbirds seek sweet nectar while rapidly beating their wings. This pollen ends up on their feathers, which they inadvertently take with them to another plant. With their wings still beating rapidly, they shake the pollen loose, which floats to other plants nearby, aiding the pollination process.

Bees

  • Solitary bees – This species of bees is well known, stingless, and are not aggressive. They possess the anatomical structures essential to pollination, like hairs that collect and transfer pollen.
  • Bumblebees – These bees use buzz pollination, which involves grasping a flower and vibrating wing muscles to loosen pollen. Wildflowers and crops like peppers and tomatoes benefit from this type of pollination. They are essential pollinators that need to be protected.

Butterflies And Moths

Butterflies and moths are useful and valuable pollinators. As they flit from one flower to another to drink nectar, they take pollen with them and bring it to other plants.

Wasps

Although wasps are known for their aggressive behavior, they offer valuable service in balancing insect populations. They do not have the anatomical structure of bees to trap pollen with their hairs since they’re smooth-bodied, but they provide incidental pollination as they carry and drop pollen from flower to flower.

Beetles and Flies

Beetles and flies are said to be the insect pollinators of the late Jurassic era. Like wasps, they have smoother bodies making them minor but still important pollinators. There are some species of flies that are beneficial to pollination.

How To Attract Pollinators To Your Garden

Understanding the role of insects and birds in the ecological process makes us think twice about swatting a wasp. In the grander scheme of things, we need pollinators, and they need us. Here are some tips to attract nature’s gardeners to your space and encourage pollination.

  • Grow a wide selection of flowers that bloom all year long.

Different insects are attracted to different flower types. It’s fascinating how in the natural world, even compatibility is required.

  • Attract pollinators by growing a variety of colors.

Bees are attracted to yellow, blue, and purple, while butterflies are drawn to flat flowers that grow in clusters. Hummingbirds favor funnel-shaped flowers in orange, red, or pink.

  • Grow fragrant and aromatic flowers.

Pollinators love aromatic flowers, making herbs like sage, basil, and lavender attractive options.

  • Create a space where they can rest and nest.

Whether it’s providing a birdbath or large screening shrubs, attracting pollinators also means you have to create a safe ecological space for them. It’s like being landlords to your working tenants. 

Conclusion

Pollinators are essential to our ecosystem. 75 to 95 percent of flowering plants need help with pollination, and the intuitive nature of pollinators makes this possible. They are integral to our survival and help maintain balance in the world. This significant impact comes from small creatures. It’s fascinating, but most of all, it’s humbling.

Dancing Cranes Join Ebetsu Plaza

Dancing Cranes Join Ebetsu Plaza

Dancing Cranes Sculpture

This story is narrated by Jim Card.

Jim had come across a picture on Pinterest showing a picture of dancing cranes in a flock. One day he was talking to Bill Peterson, our resident photographer, and showed him the photo and a video and they were both entralled with the beauty of the cranes.

A little time had past, and they were both standing in the Resource Center. Bill with his keen eye looking out the window towards Ebetsu Plaza pulls Jim over to the window, points to where the cranes sit today and says “wouldn’t that be the perfect spot to put the cranes.”

This leads to Alyson Huntting. Jim mentions to Alyson about the Bill and his conversation. A little while later, Alyson approaches Jim and tell hims she would like to commission Rip Caswell to create the cranes. From that point on, Alyson and Jim met with Rip and Alison Caswell nine times over nine months in 2019.

The Caswell’s had a similar version of herons that gave them the inspiration to create dancing cranes. The first process was a sketch. This transformed into a table-top version. Then a mold. At one of the visit, Rip formed some of the rocks at the bottom. Eventually the piece went to the foundry and Rip took Jim and Alyson to the Foundry too. During this time, the Caswell’s also had a major fire in the foundry setting the project back a few months.

During one of their visits, Alyson took notice of the fish in the Foundry and asked Rip to create two as well.

There were discussion about anchoring the fish. In the discussion of mounting the cranes Jim and Alyson went to Smith Rock quarry and picked the flat rock that the crane is now mounted on.

Before the crane was installed at Ebetsu Plaza, Alyson and Jim met with the City and City Manager to ensure that the cranes will never leave Ebetsu Plaza.

This sculpture was delayed for over nine months and was a secret until we could give the cranes a proper unveiling. Due to COVID, we ended up unveiling October 31, 2020 with Friends of Gresham Japanese Garden in attendance.

 

There are Better Ways to Prune Your Bushes

There are Better Ways to Prune Your Bushes

Spring is a good time to prune most of the trees, shrubs, and evergreens in your yard. Unfortunately for many homeowners AND landscapers this means getting out the power shears and whacking back the bushes into balls and boxes. While the resulting “Green Meatballs” might be the norm in American landscaping, it’s not the ideal way to prune woody plants.

Besides being boringly overdone, all of that tight trimming encourages dense growth that shuts off light to all but the outer leaves and slows the drying of leaves in humid or rainy weather, which translates into more incidence of disease.

Healthier and far more interesting pruning techniques are possible. Some of them can turn a plain green bush into a work of art, and most of them take just a little know-how and willingness to try something different.

There are much better ways to prune the landscape: pollarding, coppicing, topiary, Espalier, thinning.

In Japanese landscaping you will find plant art called niwaki. Niwaki is trimming, pruning, and branch-training to create a series of rounded forms that resemble clouds. You can prune densely to create a shrub that looks to have a cluster of clouds or more open to create something that looks like green puffballs on the end of branch arms. Dense evergreens take to this technique best, i.e. boxwood, yew, privet, Japanese holly, and pine.

Another Japapese art is Garden bonsai. Most people are familiar with the Oriental plant art of bonsai in which the artist miniaturizes a tree by growing it in a shallow pot and meticulously pruning the branches and roots. Something similar can be done with in-ground plants, except you won’t be digging up the plants to prune the roots.

The idea is to try and create a unique shape, ideally by pruning to encourage the shape and direction the tree wants to take. You might end up with something that looks wind-blown or that resembles the skeleton of an animal. One of the tricks is pruning just above a bud that’s heading in the direction where you’d like the branch to go. Small deciduous trees are some of the best, such as Japanese maple, dogwood, and seven-son flower, but most evergreens are fine, too, especially pine and juniper.

Spring 2018 Pruning Class

Spring 2018 Pruning Class

Dear Northwest Pruners,

We had a great time discussing Northwest Native plants at the last pruning meeting in January. We talked about which ones respond well to pruning and which ones work well in a garden context. They were not always the same!

This spring there are some great opportunities to get out and practice the craft of pruning and learn from each other. This is the second year we have been meeting and some of the gardens and trees are becoming familiar to the group. This will be a great year to observe the response to our pruning and plan for the future.

Our next class is April 7th.

Kichler Lighting

Kichler Lighting

We can never take for granted the gifts that the Garden is provided from individuals and companies that have provided our materials. One of those companies is Kichler Lighting, providing us with our low voltage LED lighting in the Garden. As one of the most significant thing that has taken place in 2017, we want to recognize the lighting donations that have come from Tom Rowe at Kichler.

Our latest supply of donated lighting came to us in July of 2017 and by August we had those light installed. With the picture that is displayed you will see that the installation took place on the bridge. As some might remember, when we built the new bridge we pre-wired the railings with wire anticipating that someday we would be able to purchase that lighting. Along with the lights for the bridge came other units that were used to highlight some of our trees and shrubs that had not been completed.

But that is not all, along with this shipment came a new transformer that powers the lighting system. This is important because the unit that was being used was over 20 years old and the timer was creating issues. With the new transformer we are not depending on a timer, but rather a sensor that allows the lights to come on at dusk and go off at dawn. It also provides the added benefit of keeping the system stable when the power goes out, meaning that the timer is not off by the length of time that the power was off and would need to be reset.

It just keeps getting better.
