The Trees Know

P71014The trees look spooky now. Box elders, honeylocusts and alders, and even some of the sycamores, have dropped so much of their foliage since that weirdly hot weather a few weeks ago. The smoky sky as a backdrop enhances the spooky factor. The trees do not seem to be too distressed. They just dropped their leaves a bit early to conserve resources. If they had not dropped foliage by now, they would be dropping it soon anyway.

Trees are not stupid. They know what they are doing. Otherwise, they would not survive as long as they do out in the elements. Sometimes, they seem to know what the weather will do before it does it; like dogs, cats and horses that start to get their undercoats early before a cold winter.

Deciduous trees and other plants defoliate for winter for a few reasons. Those from farther north probably see no need to work so hard to collect sunlight while sunlight is so minimal. Up north, days are shorter, and sunlight is diminished as it passes through so much of the atmosphere at a lower angle. Deciduous plants from colder climates shed their foliage because they know that if they do not, it will get frozen anyway. Those from snowy climates do not want foliage to collect heavy snow that can break limbs. Defoliation also eliminates much of the wind resistance that can break limbs during winter storms. There are a few advantages to being deciduous.

In California, we have a native California buckeye, Aesculus californica. In chaparral conditions, it can be ‘twice-deciduous’. It does not need to be so in less arid regions, such as the Santa Cruz Mountains. It really depends on the weather.

As a twice-deciduous plant, the California buckeye develops new foliage in spring like other deciduous plants do. It stays foliated as long as it wants to; but if things get too dry and warm in the middle summer, the foliage shrivels and falls. To a casual observer, the trees seem to die. However, between the first autumn rain and the first winter frost, California buckeye develops a second phase of autumn foliage to briefly compensate for summer dormancy. This foliage stays late until it gets frosted and falls. Winter dormancy is just like that of any other deciduous tree. In spring, the process starts all over again.

Bastards!

P71011Palm trees did not impress me much when I was young. Although striking in the right landscapes, they did not ‘do’ much. They made no fruit. They made no firewood. Only the big Canary Island date palms made any significant shade. What they did make was a big mess that was difficult to rake. They were expensive to maintain. They sheltered rats and pigeons. Their seedlings came up in the weirdest places.

Back then, the only two palms that I was really familiar with were the Canary Island date palm and the Mexican fan palm. Windmill palms were common too, but because they are so much less obtrusive, they did not get my attention. Queen palms had not yet become a fad, so were mostly in older neighborhoods outside of my world. I was aware that there was an odd type of Mexican fan palm, but never gave it much thought.

Then I went to college . . . and met Brent, from Southern California, where palms are more appreciated. I also met more palms that I had either ignored earlier, or had never seen before. After a while, Brent showed me around coastal Southern California, including the Pacific Coast Highway and Santa Monica, where I saw palm trees at their best.

I will never forget turning onto Bedford Drive in Beverly Hills, where the Beverly Hillbillies drove when they came to town. I had never seen Canary Island date palms and Mexican fan palms like that before. They were so majestic! They were so tall! They were so uniform! It did not change what I already knew about palms, but it did give me a different respect for them.

That odd Mexican fan palm that I mentioned earlier was actually the California fan palm, or the desert fan palm, which is classified as a distinct specie. It gets about half as tall, but twice as stout, with fluffier foliage. Because it is shorter and stouter, it stands straight, without bending like the taller and lankier Mexican fan palm does. It is also more genetically variable because it naturally grows in isolated oases rather than a contiguous range.

After seeing the California fan palm growing wild outside of Palm Springs, around the springs that Palm Springs is named for, it became my favorite palm. It is very stately in the right situations. It lines North First Street at Saint James Park in San Jose, and flanks the Palm Driveway at the Winchester House. Unfortunately, it really prefers to be out in the aridity and warmth of the desert. It looks rather sickly if it gets too much water.

While cruising around the Los Angeles area, Brent pointed out a few ‘bastards’, which are hybrids of California fan palm and Mexican fan palm. Apparently, they are not distinct specie, but rather subspecie. In other words, they hybridize freely. Each parent has attributes; and the bastards get the best of both.

Mexican fan palms, whether I like them or not, are very tall, elegant and graceful. They are exquisite skyline trees, with leaning or bowing trunks that can move casually in the wind. California fan palms are stout, stately and formal. If not watered too much, their straight and uniform trunks, and canopies of fluffy foliage, work nicely where conformity is desired. Bastards have trunks that are just thin enough to be elegant, but just stout and straight enough to be stately. Their canopies are more ‘lush’ than fluffy like those of the California fan palm.

Until recently, bastards were solitary trees that grew randomly from seed. They were not available in nurseries. If they had been, they would have been very variable because of their random breeding. However, someone took notice enough to cultivate what seems to be a cultivar known as Washingtonia X filibusta. (Washingtonia X filibusta is derived from the names of California fan palm, Washingtonia filifera, and Mexican fan palm, Washingtonia robusta. The ‘X’ designates it as a hybrid.) They are becoming the new alternative to the formerly all too common Mexican fan palm.P71011+

Politically Incorrect Horticulture

P71008Landscape Designer, Brent Green and I are both very professional at work. Brent is particularly well dressed, well groomed and well spoken. I happen to be simpler and plainer, but it works for the clients who respect my expertise. What our clients do not see is how we interact with each other. It would be very easy to be offended. Yet, we consult with each other almost daily, usually when Brent is driving somewhere . . . alone. We get loud, obnoxious, rude, crude, potty mouthed and just plain nasty!

Years ago, when Brent got his telephone connected to the stereo in the car, he made the mistake of driving up to a drive through window at a fast food establishment while talking to me. I listened to him place his order, and then shouted, “THIS IS A HOLDUP! GIVE ME ALL YOUR MONEY!”.

Last year, while stuck in traffic on southbound Highway 17 with the top down in the old Chrysler, I took a call from Brent. I was using some weird hands-free device at first; but when Brent started rapping about some very objectionable subject matter, I just had to share. I disconnected the device so that the call was coming through on the stereo, and turned the stereo up very loud. I just sat there calmly and tried to look as if I did not know where all the commotion was coming from, although it was obvious. I just didn’t care. Neither did Brent. He was 350 miles away.

However, not all of our nonsense is so senseless. We have developed quite a bit or our own private vocabulary and horticultural slang. It works for us because we share so much common experience. Much of the slang applies to ‘ethnic horticulture’, which refers to the gardening styles of particular ethnic groups. Brent’s favorite ethnic group to invent ethnic horticultural slang for is of course mine. Although I am only halfway of Italian descent, I can really identify with Brent’s observations of the gardening habits of people of Italian descent.

My ancestors have been here so long that the ‘old country’ refers to Sunnyvale (California). Yet, somehow, some traditions continue through many generations. My great grandfather grew many of the plants that are very stereotypical of Italian American gardening. My pa is more cosmopolitan, but he and I still enjoy some of what we learned from my great grandfather.

This is some of the slang that Brent developed for some of what I grow in my garden:

  • dago pansy – nasturtium
  • dago begonia – geranium
  • dago sunflower – dahlia
  • dago rhododendron – oleander
  • dago tomato – tomato (duh)
  • dago wisteria – grape
  • dago plum – fig
  • dago berry – olive
  • dago spruce – Italian cypress
  • dago firewood – any fruitless tree
  • dago ghetto grass – Astroturf (not in my garden)
  • dago groundcover – red lava rock or white moonrock

Small Tree In A Big Park

P71006How did the Featherstone Tree survive? (See: https://tonytomeo.wordpress.com/2017/10/05/big-tree-in-a-small-town/.) It was planted on the edge of a busy highway where heavy loads of lumber were driven by oxen, at a time when society was more interested in harvesting trees than preserving them. Yet, after more than a century, it is still here.

The Scofield Tree is a very small valley oak in an island of a parking lot at Felton Covered Bridge Park, just across the San Lorenzo River from the Featherstone Tree. In a few centuries, it might be comparable to the big valley oak that was recently cut down across the road (See https://tonytomeo.wordpress.com/2017/09/11/goodbye-to-an-old-friend/.) It is a good choice for this location because it develops a remarkably complaisant root system for such a large tree, and it is a native, so does not need to be watered.

However, it is the fourth tree to be planted here. The original California black oak that was planted when volunteers from the Community built the park years ago did not last long before getting run over by a car. It was not replaced until a small Eastern redcedar was planted on New Year’s Day of 2013. That tree was dead and crispy by summer. A bigleaf maple was planted the following winter, and sort of survived through the year, only to die the following winter. It was too late in winter to plant anything new that year, so the tiny valley oak was planted late in 2015.

Although tiny, it had a nice root system, which was more than the two bare-root trees before it had. The hope was that if it could survive getting peed on by dogs long enough to disperse roots, it would be fine. It started to foliate the following spring, only to get much of the bark gouged away by a ‘gardener’ with a weed whacker. The poor tree nearly died, but somehow survived and started to recover. However, it did not recover fast enough to get ahead of the dog pee. It really seemed to be struggling through this year, and is now getting ready to defoliate for autumn. It really needs to get some height next year. Small trees are just too vulnerable to all that goes on in a park.

Each of the redwood trees around the perimeter of Felton Covered Bridge Park is a memorial tree, sponsored by friends or family of the deceased. An additional sweetgum tree is a memorial tree for a French bulldog. Some of the trees are outfitted with memorial plaques. The tiny valley is named the Scofield Tree for an old friend of the Community, Jeff Scofield, who passed away in the spring after the tree was planted; but it is really a memorial tree for a few people who passed away within a few years of that time. The Scofield Tree was sponsored and planted for the deceased by Felton League, an informal group of displaced and socially disadvantaged people of Felton, and their friends. Their Facebook page can be found at https://www.facebook.com/Felton-League-520645548069493/.

Perhaps what is written now about the Scofield Tree will eventually become part of the history of Felton, and be summarized on a plaque like the one on the Featherstone Tree. It would be excellent enough if the Scofield Tree simply does what good treed do in a park for a few more centuries.

Big Tree In A Small Town

P71005Trees get planted all the time. Apparently, nature does not do the job adequately. Trees get put into specific locations to provide shade, produce fruit, enhance a landscape, obscure a view, or for any of a vast number of reasons. It is amazing that they are as accommodating as they are. It is rather presumptuous for us to think that they actually want to live with us in our synthetic environments as much as we want to live with them.

The coastal redwood is the tallest tree in the world. It can live for thousands of years. An individual tree can produce enough lumber to build a small house. It is no wonder that they are so impressive to anyone who sees one for the first time.

Many towns within the natural range of the coastal redwood were established for the redwood lumber industry. Felton, in the Santa Cruz Mountains, is one of those towns. George Featherstone of Ottawa came to Felton in 1888, and was so impressed with the coastal redwood trees, that he planted one in the middle of town only a few years after his arrival. This tree was only a teenager when redwood harvesting increased to supply lumber to rebuild San Francisco after the Great Earthquake and Fire of 1906, and then to develop the rest of the San Francisco Bay Area.

More than a century later, the Featherstone Tree is still here, and is the biggest thing in the small downtown. The Community Deck was built around it by volunteers from the Community many years ago. It is not as tall as trees in the forest are, but only because it does not need to compete with them. It is shorter and stouter, and really seems to enjoy being the center of town. It is quite the celebrity.

Mr. Featherstone had no idea of how important the tree he planted would become. It would be nice if we all could do such nice things for our communities, but then the world would be much too shady.

P71005+(‘ninties’ means the 1890s.) This Redwood Tree was planted in the early ninties by one of Felton’s early settlers, George Featherstone, a man who knew the wonder and beauty of these trees. Born in Ottawa, Canada in 1872, he came to the San Lorenzo Valley on March 17, 1888. He died on September 27, 1947.

What Is Killing The Box Elders?

P71004Remember our concern about the mistletoe? (https://wordpress.com/view/tonytomeo.wordpress.com) You might think that everyone would be pleased to see it gone. Yet, there is the concern that whatever killed the mistletoe might kill something else. That is what happened when the SODS killed so many coast live oaks after being ignored for a long time in the tan oaks. We were aware that the tan oaks were dying, but because the trees were so unpopular, we were not too concerned about it.

Now the box elders are dying around Felton. It is hard to say how widespread the problem is because it has not been investigated yet. Like tan oaks and mistletoe, the native box elders are not exactly popular trees. They do not even make good firewood. We only use them as firewood to get rid of them. However, when so many are die, it leaves big holes in the forest canopy. This is not really a problem, since the forest will have no problem filling the holes in, but it certainly gets our attention. Will the disease or insect pathogen that killed the box elders kill something else next?

The trees seemed healthy as they defoliated last autumn. They were bare through winter when the San Lorenzo River came up higher than it had since 1982. A few box elders got taken away by the River, along with all sorts of other riparian trees from the flood zone, but that is to be expected. Then, after the River receded, many box elders that were in the flood zone did not foliate in the spring. A few foliated, only to have their new foliage shrivel and die shortly afterward. Some of the dead trees became infested with boring beetles. All of the dead trees deteriorated rapidly through summer, and some have dropped big limbs or fallen over.

What is happening with the box elders could be completely normal, and caused by an endemic pathogen; but it makes one wonder. There are so many new insects and diseases being brought in with plants arriving from all over the world, without any regulations to limit the spread of such insects and diseases.P71004+

War Of The Worlds

P71003To a little kid, it really had the potential to be a scary movie. I did not understand all of it, but I got the important parts. Mars was red, so was probably near Oklahoma. Apparently, the people from Mars had big scary machines that destroyed anything and anyone that was in their way. I did not perceive much of a threat because my parents let me watch the movie. (We children could not watch really scary movies.)

Shortly after watching War of the Worlds, I went for a long walk with my older sister and some of her friends into the last remnant or orchard that was such a prominent part of our world. We went out onto a new section of roadway beyond where our street used to end, and turned east on a completely new street that was not there before. The fresh new pavement and neat curbs seemed so flat and desolate . . . and expansive compared to the orchard that it now divided. I wondered how the trees got out of the way of this thing. Obviously, some moved to the left, and others moved to the right.

We eventually arrived at a larger clearing off to the left of this new street. Within this clearing, there were huge concrete rectangles with short pieces of rebar sticking up from their perimeters. One of the concrete rectangles lacked rebar, but was outfitted with four tall poles that curved on top. They looked something like those scary weapons on top of those machines that came from Mars. My sister confirmed my suspicions by explaining that the big concrete rectangles where where the flying machines landed when they arrived. Now I was getting a bit scared.

A few days later, we started to hear strange noises coming from the orchard. I was not allowed to go that far into the orchard without my sister, and was too afraid to go investigate anyway. The noises were mechanical and metallic, mixed with the sound of what seemed to be a big diesel engine and wood breaking. I dismissed them as not ‘too’ terribly threatening at first; but by the next day, they were closer! Each day, they got closer, until I could actually see motion through the trees. Something yellow was moving around in there, and small puffs of black smoke sometimes squirted out above the trees. I was terrified! I told my mother that the mean people from Mars were out there destroying everything like in the War of the Worlds!

She explained that there were no mean people from Mars in the orchard, but that a new park was being built on the site. Well that did not help much. What is this ‘park’? My mother explained that it would be a place where kids could play and run around and climb things and play games . . . and you know. Well duh, that is what the orchard is for. She said that it would be better. I wondered what could possibly be better than the orchard. This is something that I need to see!

Well, for the next two days or so, as they tore out the last two rows or so of trees, it became apparent that they yellow machines from Mars that spurted out black smoke were bulldozers gouging the trees right out of the ground. No one even bothered to cut up the firewood to leave on the side of the road like was typically done. The trees were unceremoniously piled up and burned. I was no longer terrified. I was saddened and confused. I could not understand why anyone would want to do this to the most important part of our world.

The big concrete rectangles with rebar protrusions were not landing pads for the flaying machines from Mars. They were the foundations and floors of the Recreation Center for the new park. The concrete rectangles with the four curved poles that seemed to be an assembly site for the weaponry from Mars simply became two basketball courts. The curved poles were outfitted with backboards and hoops. The orchard, devoid of trees, was leveled in most areas and mounded in others, and mostly covered with a vast lawn. New trees were planted around the perimeter and within landscaped areas around the Recreation Center. I suppose as far as parks go, it was a nice one.

The only problem with it was that we did not know what to do with it. The new trees were too small to climb or hide behind or really to do anything with. The lawn was nice, but there was way too much of it. The Recreation Center was nice inside, but we wanted to be outside. Eventually, we learned how to enjoy our park, and it really was nice; although it will never be an adequate substitute for an orchard. Our suburban (or some might say ‘rural’) world was invaded and, unlike in the movie, conquered by a more urban culture.

I would not say that one culture is any better than the other. However, I will say that I believe that there was a certain advantage to knowing the orchard and some of the nearby undeveloped wildlands the way that we did. I really believe that it was more educational than the refined and synthetic landscape of the new park. The maintenance of the park certainly required some degree of horticulture. There are trees, lawn and all sorts of shrubbery and perennials. The orchard had only trees and mustard. We interacted with it differently somehow. This is something that I can not explain adequately. It can only be experienced.

Goodbye To An Old Friend

image(16)

After decades of deteriorating structural integrity, Quercus lobata of Felton finally succumbed to a need to prioritize public safety, and passed away at home in Felton Fair on June 20, 2017. His age is unknown, but may have been about three centuries. He was born in Felton before Felton was, and lived his entire life here. In the idyllic alluvial meadow between Zayante Creek and the San Lorenzo River, he was a simple forest tree for most of his career, and only became a distinguished shade tree when Graham Hill Road was built. Instead of retiring later in life, he became the most prominent tree in the parking lot when Felton Fair was constructed. In his spare time, he enjoyed feeding neighborhood squirrels. A tree of few words, or really none at all, Quercus lobata never complained about anything, even when cars crashed into his bulky trunk, and stripped away large portions of bark where decayed cavities later developed. His remains will be scattered as mulch,and used to warm homes throughout the region. Ashes will be scattered as stoves and fireplaces are cleaned. Rings will be counted privately. Quercus lobata is survived by an unknown number of children, countless squirrels, and countless admirers of various specie throughout Felton.

The obituary above was serious business when it was written. What it does not mention is that the deceased did not fall down or die completely of natural causes. It was cut down after dropping a very large limb onto a roadway, demonstrating how dangerous it could be. It would have gotten more dangerous if it aged and deteriorated more. No one wanted it to be cut down. It was just too necessary.

This is the part of the job of arborists that non-arborists do not seem to understand. We arborists love our work, and we love trees. However, that does not mean that we object to the removal of each and every tree. The people who live with trees are more important. Any tree that blatantly endangers people or property must be removed or made safe.

Unfortunately, valley oaks deteriorate and fall apart for many decades before they finally die. This particular tree might have survived for quite a while if it had not been cut down. It also would have continued to drop limbs.

Distinguished old trees are always the most difficult to condemn. No one is old enough to remember when they were not here. They witnessed more changes to their little part of the world than anyone. Without going anywhere, some of them here in California visited three different countries; Spain, Mexico and the United States of America.

In the end though, death is perfectly natural. The tree had spent centuries doing what it was put here to do. It was time for it to go. Behind the stump in the picture, one of its babies is already becoming a nice young tree. Another one is just to the east, just beyond the left edge of the picture. They might shade the road and driveway for a few more centuries. What history will they see during that time?

California Sycamore

70913No other big tree has trunks as sculptural as those of the California sycamore, Platanus racemosa. They bend and groove so irregularly, seemingly without direction, that it is a wonder that old trees in the wild eventually get a hundred feet tall. Some trees have a few trunks. The mottled beige bark is quite striking both in the shade of the broad canopy, and while trees are bare in winter.

California sycamore is a surprisingly well behaved street tree, but only for a few decades or so. The roots are quite complaisant. The main problem is that the bulky trunk eventually gets wider than the parkstrip. Another problem is that such a big tree drops a huge volume of foliage in autumn, and then again in spring as anthracnose ruins much of the new foliage. The big palmate leaves are about eight inches wide, and covered with tomentum (fuzz) that is irritating to the skin.

Street Wise About Street Trees

70913thumb

There is no such thing as a perfect tree. All trees have foliage that one way or another, eventually falls to the ground. All trees have roots that might try to displace something that gets in their way. Many trees are messy in bloom. Some make messy fruit. Except for palms, all trees have branches that can be broken by wind. Just about any tree can be blown over if the wind is strong enough.

This is why the selection of trees that are appropriate to each particular application is so important. Finding trees that provide enough shade, obscure an unwanted view, or perform any specific function is one thing. Finding trees that behave while performing their assigned tasks is something else. There are always compromises. A certain degree of bad behavior will likely be tolerated.

Street trees for a parkstrip between the curb and sidewalk can be the most challenging trees to select. There are so many variables to consider. Many neighborhoods have saved us the trouble of selection by prescribing a specific tree, or maybe limiting the choices to only a few species, whether or not they are actually appropriate. Otherwise, we are on our own, to select whatever we like.

Microtrees might seem like good choices. They do not get big enough to damage a sidewalk, or make much mess. These are trees like crape myrtle, purple leaf plum and photinia (in tree form). These trees can be proportionate to narrow streets, but really do not shade much more than a single parking space. Because they are so low, they need serious pruning for adequate clearance.

Mid-sized and bigger trees like Chinese pistache, honeylocust maidenhair tree and some of the modern hybrid elms certainly cause more problems, but might be worth the bother. They shade curbside parking and part of the front yard nicely. Like small trees, they need to be pruned for clearance, especially over the roadway, but they eventually grow up high enough to be out of the way.

It seems that trees that exhibit some of the better characteristics for street trees are deficient in other ways. Australian willow has very complaisant roots, and is very resilient, but also branches low, and is not much to look at. Fern pine and several oaks are excellent street trees for decades, but eventually get big. Root barriers will delay, but not prevent roots from damaging sidewalks.
