Six on Saturday: Dia De Los Muertos

 

Dia de los Muertos, or Day of the Dead, was yesterday, Friday, November 2. However, the dead are still dead. They don’t need a special day to be so. In fact, they do it every day of the year. Dia de los Muertos is just one day of celebration to honor them.

Dia de los Muertos is not for plants though. Dead plants just get cut down and disposed of. Some get composted. Dead trees get recycled into firewood. These are six pictures of five species of dead plants that I needed to contend with in the week before last.

1. Rhododendron. I really do not know what killed this group of rhododendrons. It is not uncommon for one to die. With all the rhododendrons in the landscape here, a few dead ones get removed annually. However, it is rather disconcerting that a few died all in the same area at the same time. All their dead stems were rather sculptural. They were removed just after this picture was taken. Of the five specie in these six pictures, this is the only species that is not native.P81103

2. Madrone. Bits and pieces of madrone commonly succumb to blight, sort of like fireblight in apple and pear trees. Sometimes, entire trees are killed like this one. It is fire wood now.P81103+

3. Ponderosa pine. The forest does not burn as frequently as it used to before people were here to extinguish forest fires. The lack of restorative fires interferes with regional ecology. Not only is the forest becoming congested with unburned fuel, but pathogens are proliferating in the aging flora and consequently accelerating the deterioration of the forest, which increases the combustibility. It is a natural process designed to correct an unnatural lack of restorative fires, but does not go well for those of us who live here. Ponderosa pines can live for a few centuries. However, in our compromised ecosystem, many succumb to pathogens while still relatively young. This one will need to be removed next year. Once dead, they deteriorate and start to drop limbs within the year.P81103++

4. Coast live oak. This is one of the most adaptable of tree specie in California. It lives right down to the beach, and into interior valleys, and up the summit of the Santa Cruz Mountains. It does what it must to adapt to the various environments within its range. It often lives in groves of the same, where it is more likely to burn every few decades or so. In spacious valleys, it is often not so social, with individual trees living in relative isolation from their neighbors. Grass fires can burn harmlessly between such trees, allowing them to live for a few centuries. Wherever they are, they develop more trunks than they need. As they mature, subordinating trunks like this one, get shed naturally and harmlessly. It is not as bad as it looks. In the wild, it would rot and fall to the ground as the rest of the tree continues on as if nothing happened. In our landscape, it was cut and taken away.P81103+++

5. Coast live oak. This dead foliage is a bit more alarming because I do not know what caused it. It is probably superficial damage caused by a girdling beetle. I did not look for evidence. Sudden Oak Death Syndrome is a much more serious disease that is all too common here (and a very sensitive subject). Fortunately, this particular specimen is a small and unimportant tree that I would not mind cutting down if it were to succumb. I just do not like to be reminded of how rampant Sudden Oak Death Syndrome is here.P81103++++

6. Tan oak. This tree really did succumb to Sudden Oak Death Syndrome, Phytophthora ramorum, which is more commonly known here as SODS or SOD. A few adjacent tan oaks that succumbed last year are already very deteriorated and will soon be dropping limbs if not removed over winter. These particular trees are not very important to the surrounding forest. Their removal will actually improve the collective landscape, and give the surrounding redwoods more space to expand. The problem with SOD is that we never know which oaks it will kill next. It kills trees before we know they are infected. There is no remedy.P81103+++++

Argyle Apple

51104What an odd name. It sure sounds interesting, like some sort of exotic fruit tree. Alas; argyle apple is a eucalyptus; to be specific, Eucalyptus cinerea. Compared to most other eucalypti, it stays rather low. It barely gets as tall as a two story house, even if it gets broad enough to shade most of the backyard. The rusty brown bark becomes roughly furrowed. The irregular branch structure can be quite sculptural.

The main attraction of argyle apple is the aromatic silvery foliage. Young trees are outfitted with circular juvenile leaves that are attached directly to the stems without petioles (leaf stalks). Lanceolate adult leaves are as silvery as juvenile foliage is. (Juvenile foliage of most other eucalypti is more colorful than adult foliage is.) Aggressive pruning of small trees keeps foliage juvenile for a long time.

Actually, those who know how to work with it might pollard or coppice argyle apple. Pollarding eliminates all foliated stems at the end of winter, but for the rest of the year, allows vigorous arching canes of very silvery juvenile foliage to spread outward from a few stout limbs on top of a trunk. Coppicing allows the same sort of growth from stumps just above grade.

Straight And Narrow For Trees

30731thumbIn the wild, trees do just fine without any help from anyone else. They certainly are not stupid. Their roots disperse for adequate stability. Their trunks grow upward as limbs spread outward for adequate structural integrity. Trees only need help in landscape situations because they are expected to perform so unnaturally. From the very beginning, their trunks are bound and their roots are confined.

While they are growing in the nursery, trees are bound tightly to stakes to keep their trunks straight. Unfortunately, this binding inhibits natural development of trunk caliper. Since they can rely on stakes for support, trees do not waste resources on developing the strength of their own trunks. The various eucalypti are particularly sensitive, and can bend over to reach the ground when unbound.

Roots are confined to cans (pots) or boxes because that is how trees are grown in the nursery. Even in regions where trees are field grown, roots must be severed when trees get dug and moved. Many types of trees do not mind much, and are eager to disperse roots into a new landscape as soon as possible. However, oaks, pines and many others do not recover as efficiently from confinement.

Once in a new landscape, most trees need to be staked to recover from being staked and confined in the nursery. New sturdier stakes that extend below the confined root system into soil below should stabilize newly planted trees. This is particularly important for evergreen trees that will be blown more by wind than bare deciduous trees, and particularly because most trees get planted in autumn and winter.

These new stakes should be installed a few inches away from the tree trunks so that they can support the trunks loosely when the tightly binding nursery stakes gets removed. To prevent abrasion, new straps should be somewhat loose, and cross over between the trunks and stakes. A pair of opposing stakes, with straps supporting in opposing directions, is sturdier than a single stake. A few straps may be necessary.

The new crepe myrtle trees in the picture above remain  bound to the stakes that they were grown with in the nursery. Sturdier stakes that can support the trunk in a less constrictive manner have yet to be installed.

KinderGarden

P81028

By modern standards, the public schools that I attended in the early 1970s would be considered to be bleak and primitive. The building were utilitarian and simple, from about twenty years earlier. The landscaping was comparably simple, with a big lawn and proportionately big shade trees. A screen of alternating Monterey pine and Monterey cypress was hedged on the southern half of the eastern boundary of the schoolyard. The only deviants to the simplicity were a few significantly older trees on the northern half of the eastern boundary of the school yard. There were two coastal redwoods, a Canary Island date palm, a cedar, and a spruce of some sort. They were all quite mature, and were likely remnants from an old farmhouse that was there before. Perhaps they wanted us to be aware that everything changes.
On the way to kindergarten, back when children were allowed to walk to school, I weaseled my way underneath the first Monterey pine and Monterey cypress on the southern end of the fence line, and fell asleep. I do not remember how long I stayed there, but it was long enough to get in serious trouble with my very worried kindergarten teacher. After that, I could only visit those two trees in passing, and perhaps stop only briefly to smell the foliage or shake some of the rain away.
Nearly four decades later, but only a few years ago, I was assigned the grim task of composing the arborist report that would justify the issuance of a permit to remove that same Monterey pine, which was the last that remained of the hedged trees that I remember. I did not know that when I went to the site. I was just told that it was a ‘pine’.
Visiting the old school was not a pleasant experience. The entire site was surrounded with a prison like fence and saran screens to obscure the view inside and out. There were no open gates. I needed to be escorted to the tree by a professional chaperone. Much of the schoolyard had been very synthetically landscaped with microtrees and pretty flowering shrubbery that was intended to impress parents rather than appeal to children. It is bad enough that there are no orchards or open spaces remaining in the region, but it is worse that children are deprived of the open lawns and trees and natural spaces that my generation had taken for granted on the grounds of our school. Are children even allowed to climb trees anymore? Do they know what dirt is? Can they observe a chrysalis split open to reveal a new butterfly before the gardeners shear the shrubbery and take the learning experience away? It was saddening.
Once I realized that the tree that I was expected to condemn was my old friend, I asked the chaperone, who seemed to know a bit about facilities at the site, why anyone would want the now mature tree to be removed. I knew that it had been mutilated while young, but was impressed with how it somehow recovered and developed a well structured trunk. I thought that perhaps someone noticed something that I was missing in my inspection. People who are not arborists are sometimes alarmed by something that is perfectly normal for a tree, such as furrowed bark, or slight seasonal foliar discoloration.
The chaperone explained that the tree needed to be removed simply because it did not conform to the style of the rest of the landscape. I waited for the rest of the answer, but that was it. The tree did not conform.
Nothing gave me more pleasure than to explain that after my evaluation of the health, stability and structural integrity of the subject, I could find no justification for removal.
I was dismissed.
Yes, it was worth it.
However, I knew that for the right price, another arborist would be pleased to condemn the tree. The picture of what remains suggests that the arborist who did so was not even professional enough to get his crew to finish the job. How does this dead stump conform to the rest of the landscape?
Those old trees, the redwoods, palm, cedar and spruce, were right. Everything changes.
The Monterey pine that would not conform is gone now, but it was right too.

My First Tree

71108Calocedrus decurrens. Incense cedar. The first tree that I ever planted was a small incense cedar, like the tree in the picture here. Of course, it was not this big when I planted it.

It came from my maternal grandparents’ cabin near Pioneer, in the foothills of the Sierra Nevada. It was a wild seedling that might have been pulled up because it was where the cabin was to be built. My grandmother planted it into a small wooden planter in the backyard. Once it recovered and started to grow, she gave it to my parents, who had me plant it on a small hill in the back yard. Although not native to the Santa Clara Valley, it did well, and grew tall and lean. I tend to compare all incense cedars to my first tree.

Almost all are older and bigger, with plump trunks. I can guess from their age that most were planted during the Victorian Period. Quite a few were planted half a century later, during the 1950s, when Monterey pine and Monterey cypress were too commonly planted. Not many incense cedars are young. It is as if they had been available in nurseries until the early 1970s, and were not grown much after that. I planted a few in Scott’s Valley back in the 1990s, on the southern margin of what is now Sky Park, but only because my colleague happened to grow them.

Because it was less expensive to transport ‘relatively’ local lumber than to import Eastern red cedar lumber from the East, incense cedar provided the veneer for closets of old homes here, as well as cedar chests. Small groves of incense cedar were grown in the Santa Cruz Mountains as a local source of cedar wood. Now that cedar closets and chests are no loner necessary to repel moths from woolens and furs, the naturalized groves are abandoned, and now grow wild. I know that they are technically not locally native, but I still like to see a few of them around. They look so much like my first tree.

My Private Heritage Tree

P81020+++++I really believed that I had something special here. A few fruit trees that are either remnants or descendants of remnants of fruit trees of the old Zayante Rancho have survived on a vacant parcel east of town.
There are two pear trees, a prune tree and an apple tree. The pear and prune trees are too overgrown to make much fruit. Almost all of the fruit that they manage to produce is too high to reach, and of inferior quality. They could be renovated, but the process would require severe winter pruning for several years.
However, the apple tree is still somewhat compact and quite productive. Much of the fruit is within reach for the ground. Much of the rest can be shaken from the tree without damaging it too much. Although abandoned for decades, someone actually put the effort into pruning the apple tree a few years ago. It still needs some major pruning, but would be easier to renovate and restore than the other trees.
I can not identify the cultivar of the apple, or even the type. The fruit looked and tasted like some sort of Pippin apple earlier in the season, but is now slightly more blushed than other familiar Pippin apples in the region. It could of course be another cultivar of Pippin. It is not very juicy, but is quite richly flavored. Winter pruning to concentrate resources would probably improve the quality of the fruit.
Until recently, anyone who wanted to forage for a bit of fruit from these few fruit trees had open access to them. Both prunes and pears needed to be knocked out of their trees, and collected from the ground. Timing was critical for the prunes. They would be unripe if a few days early, or squishy and on the ground if a few days late. Apples were the most popular because they were more abundant and easiest to collect from the tree.
Unfortunately, the vacant parcel needed to be fenced. Only those who are involved with maintenance of the parcel have access to the trees now.
Well, I happen to occasionally work for one of those privileged few, which indirectly gives me access to the distinguished trees.
Of course, I could not resist bragging to my Pa about my privileged access to these now private heritage trees, especially the apple tree. As I said earlier, I really believed that I had something special here.
To my surprise, and perhaps disappointment, my Pa is very familiar with my special apple tree! I had nothing to brag about that he could not also claim! He actually picked apples from it with his mother when he was a little tyke living on Ashley Street in town!

Horridculture – Arborists Are . . . Unique.

80221thumbThere are many different types of horticulturists. We are all unique, both individually as well as collectively within our respective professional group classifications. For some of us, individuality interferes with conformity to the collective generalizations that are so commonly associated with our collective groups. For some of us, the stereotypes are a perfect fit.
‘Primarily’, I am a nurseryman. We are the intellectual ones. Well, at least we get most of the credit for being the intellectual ones. Most of us really are quite intellectual. Most of us are rather humble about it.
My excuse for nonconformity to the latter is that I am ‘secondarily’ an arborist. Arboriculture is something that I have never been able to get away from. I did an internship with the most excellent arborists in the entire universe in the summer of 1988. After all these years of mostly growing horticultural commodities, I still sometimes conduct inspections and compile reports for trees that other arborists and their clients are concerned about.
You see, arborists are the passionate ones. One might say that we are enthusiastic, fanatical and zealous. Nurseryman might say that we lack restraint and cultural refinement. It is not such a simple task to distinguish between exuberant dedication and primitive efficiency. Regardless, most arborists do not like to write reports. It is easier to get a nurseryman to do it.
In fact, arborists do not like to write much of anything. There are several elaborate blogs that are written by nurserymen; but blogs written by arborists are rare, with brief and infrequently posted articles.
The irony of this is that it is more important for arborists to express professionalism with clients than it is for nurserymen. Arborists are out in the real world, working directly with clients. Nurserymen work on the farm, isolated from those who purchase the horticultural commodities that are grown there.
Arborists are horticulturists who specialize in the horticulture of trees. The best are just as educated and experienced as nurserymen are. In fact, much of my education was derived from arborists. Yet, arborists are so often regarded as mere gardeners who go up trees.
That is where I get offended. Yes, I am aware that there are hackers out there. I am also aware of what clearance pruning of utility cables entails. I also know how serious my arborist colleagues are about their profession. They are not to be compared to gardeners.
There are many gardeners who are just as educated, experienced and proficient with horticulture as arborists and nurserymen. However, the majority of gardeners are not. I will not elaborate on this presently. It will be the subject of other rants. I have written articles about my professional experience with gardeners already, and none of them go well. (I lack experience with good gardeners simply because they have no need for my expertise.)
The picture above is an example of a sycamore that is pollarded in the traditional English style. The work is exemplary, and is repeated annually every winter. It is no simple task. I certainly would not want to do it. I can not think of any other nurseryman who would know how to do it properly. It is the work of a very skilled and very experienced arborist.

Bigleaf Maple

81024It is native from the extreme southern tip of Alaska to the extreme southwestern corner of California, but not many of us will see bigleaf maple, Acer macrophyllum, in our neighborhoods. It is planted only rarely, particularly where winters are mild. Relative to other maples, its roots can be more aggressive, and its shade can be darker, so is likely to interfere with lawn and other plants.

Mature trees in exposed situations can get more than fifty feet tall and quite broad. Old wild trees that compete with other trees in a forest can get three times as tall! The big palmate leaves from which the name is derived are about half a foot to a foot wide, and can get a two feet wide on the most vigorous or shaded growth. They turn a nice golden yellow in autumn, even in mild climates.

Bigleaf maple is like the sugar maple of the West. The sap can be processed into maple syrup and sugar. The wood is made into furniture and musical instruments. The very ornamental wood known as bird’s eye maple is derived from burl growth of various maple specie, particularly bigleaf maple. Bigleaf maple is uncommon in landscapes only because it is so aggressive and big.

Indian Laurel

61019It is hard to believe that such a delightfully robust and luxuriant tree like the Indian laurel, Ficus microcarpa nitida, can be so problematic. It looks so perfect, with lustrous evergreen foliage, like something that would be seen on Sesame Street. The broad and dense canopy is very symmetrical and neat. The stout trunk and limbs, outfitted with whitish gray bark, are bold and sculptural.

The problem is that the roots are so extremely aggressive. Buttressed roots elevate curbs, sidewalks and anything else that they can get under. Fibrous roots clog drainage, and strangle roots of more complaisant plants. Indian laurel is a tree that really needs room to grow. The canopy can get wider than fifty feet, and roots will spread much farther if they want to. Fortunately, Indian laurel shorn as a hedge has less foliage, so does not need to disperse roots so extensively.

Memorial Memorial

P81014The little Memorial Tree in Felton Covered Bridge park that I so frequently write about is not the first to be planted there in its parking lot island. It is actually the fourth! The first was a California black oak like the other four in the other islands. They were all planted with the original landscape. It did not live there long before getting run over by a car. The island was empty for many years.

The second tree (above) was an Eastern red cedar that I brought from Oklahoma. It arrived here very early in the morning on the last day of 2012, in a bag with a few others that I pulled out of the ground the day before we left. They may be nothing special within their native range, but they are very exotic to me. At the time, I had no plans for the small trees. I just wanted to grow them.

I was downtown and up late the following night when I realized that it was nearing midnight between 2012 and 2013. I took out a trowel, dug a small hole in the island, and planted one of the Eastern red cedars right at the moment that one year changed to the next. I did not give it any more thought than that. Otherwise, I would have preferred a native species like the Park was originally landscaped with.

Sadly, that tree lasted only a few months before succumbing to what dogs do to young trees in parking lot islands. It was a bare root tree, so was not very resilient.

The third tree (below) was a native bigleaf maple that was planted the following winter between 2013 and 2014. It did not get much more planning than the Eastern red cedar. I found it growing on the side of the road where it would have been killed by vegetation management within the utility easement. Like the little Eastern red cedar, I pulled it up and planted it bare root. It was a better choice in some ways, but would have needed to be watered by bucket for the first few years. It survived through the first year and half way through 2015 before it too succumbed to what dogs do. I was being optimistic by thinking that a bare root tree would survive that.

The fourth tree is the little native valley oak Memorial Tree that is there now. I found it for just a few dollars at a local nursery. It was planted in the winter between 2015 and 2016, so this was its third summer. It was a canned tree, so started with more of a root system than the previous two trees that were planted bare root. Nonetheless, life out in that exposed parking lot island is not easy. The tree was severely damaged by weed whackers both in 2016 and in 2017, so barely grew, and is recovering slowly. It is quite well rooted now, so should have a much better season next summer.

It includes a link to another previous article, which also links to other older articles. I really do not remember how many updates I have written about the Memorial Tree.P81014+
