Scofield Tree Update

P71212+KThe sad little Scofield Tree in Felton Covered Bridge Park did not do much this year. (https://wordpress.com/read/blogs/135014809/posts/322 and https://tonytomeo.wordpress.com/2017/12/02/felton-covered-bridge/) In fact, it grew only about five inches taller, so is now only about four feet tall. The damage from the weed whacker really set it back. Growth was healthy on the side shoots, but that growth will need to be tucked back to promote apical dominance. The good news is that the vigor and health of the foliage of the sideshoots indicated that root dispersion was likely adequate to sustain healthier and normal vigorous growth next year.

Although the sideshoots will get tucked back to limit their competition with vertical growth of the main trunk, the stubble will remain to promote caliper growth of the trunk.

The trunk will be bound like a tree in a nursery; and the bound trunk will be staked for stability. Binding outside of a production nursery may not seem to be horticulturally correct, but is necessary for a straight trunk. The staking is done more to protect the tree in such a high traffic area than to support the tree. It would be better for the tree to do without binding and staking so that it can learn to support its own weight. Once the straight section of trunk is taller than about six feet, the bindings will be loosened, and eventually eliminated as the trunk lignifies into form.

A bit of fertilizer will be added to the soil around the tree before the last rains of winter. This might seem like cheating, bur for right now, the tree is too small to be safe in such a high traffic area. It will also be irrigated occasionally after the rain stops. It does not get much water, but will get enough to keep it vascularly active through the growing season. Too much water promotes shallower roots, which might damage the nearby concrete curbs and asphalt pavement. Valley oaks naturally disperse their roots very deeply, so the curbs and pavement should be quite safe for a century or so.

Dead Box Elder Update

P71223P71223+What is killing the box elders? (https://tonytomeo.wordpress.com/2017/10/04/what-is-killing-the-box-elders/) I still do not know. I know that does not sound like much of an update. All I can share is some pictures of secondary symptoms observed now that the affected trees are deteriorating.

The two pictures above, although not relevant to any symptoms, are important to our Community because the historic Felton Covered Bridge just got a new roof! (https://tonytomeo.wordpress.com/2017/12/02/felton-covered-bridge/) Dead box elders that are already starting to destabilize and collapse are now leaning onto the edge of the new shingles! They really need to be removed before winter storms move them around, and they dislodge any shingles.

The first of the two pictures below show basidiocarps associated with fungal decay of the trunks and roots. This decay destabilized and compromised the structural integrity of the necrotic trees with remarkably efficiency. The trees died only last spring, and are already collapsing! The second of the two pictures below simply shows decaying bark peeling from a necrotic trunk.P71223++P71223+++

This all happened so suddenly. Like SODS (Sudden Oak Death Syndrome) it is likely to be misdiagnosed a few times before the primary pathogen is actually identified. Also like SODS, it may be ignored as an isolated situation affecting a few trees that are not very popular anyway. When SODS first started killing a few of the unpopular tanoaks, it did not seem like much of a problem. It did not get much attention until it started taking out majestic coast live oaks that had been healthy for centuries.

The two pictures below show a cross section of a necrotic trunk that needed to be cleared from a bridle trail. Galleries have been excavated by the larvae of unidentified boring insects. The second picture is merely a closeup of the first.P71223++++P71223+++++

Santa Ana Winds

P71221+They have been a part of life in Southern California longer than anyone can remember. The Santa Ana Winds have been blowing down from the high deserts to coastal plains long before people arrived in the region. They are arid and usually warm before they leave the Great Basin and Mojave Desert, and they get even warmer as they flow downhill through mountain passes. That is what makes them so dangerous during fire season. Wind alone accelerates wildfire. Warming arid wind desiccates fuel, making it more combustible before wildfire arrives.

Santa Ana Winds are so regular that they affect how tall trees grow within the regions of the mountain passes where Santa Ana Winds move the fastest. Tall Mexican fan palms that grew up straight where sheltered from wind near the ground innately lean with the prevailing wind as they grow up and become more exposed. Those closer to the narrow canyons lean the most. It is something that arborists recognize everywhere around the Los Angeles Basin. They can tell how strongly the Santa Ana Winds blow in any particular neighborhood by how Mexican fan palms lean.

Santa Ana Winds can be strong enough to break tree limbs, and blow trees down. In the past few days, they have been making quite a mess in the Los Angeles region; although not as much of a mess as they are making in conjunction with the Thomas Fire in Santa Barbara and Ventura Counties, which may already be the biggest wildfire in the modern history of California.

Overnight, Santa Ana Winds blew this California pepper tree onto a swimming pool in Los Angeles. Tree services, landscapers, gardeners and those who enjoy gardening will be busy cleaning up such problems for the next few days, as Santa Ana Winds continue.

Mistletoe Un-Update

oklahomaThere is still no news about why mistletoe disappeared this last year in our area. No one really noticed it missing until late in summer. The absence of mistletoe became more apparent as deciduous trees that had been infested with it last year defoliated in autumn. What is even more strange is that the dead mistletoe plants deteriorated so quickly and efficiently that they are completely absent, as if something ate all the mistletoe, or took it away. The only evidence of former infestation in some trees are the swollen portions of stems where mistletoe had been attached. An article about this mysterious absence of mistletoe can be found here; https://tonytomeo.wordpress.com/2017/09/24/where-has-all-the-mistletoe-gone/ .

Someone who harvests mistletoe from local trees, both to eradicate it from a few trees, and also to sell it in local markets, made an interesting observation about the absence of mistletoe just within the past few day. He found that some mistletoe survives, but only in the upper extremities of tall trees. Most of the trees are locust trees, perhaps because they happen to be taller than most of the other trees that had been infested. One infested tree is a black walnut. The viable mistletoe plants are somewhat young and small. Larger plants or colonies that were as high as the smaller surviving plants are gone. Specie of mistletoe that infest coast live oak and some conifers have not been observed.

There are several variables that could account for the survival of relatively small mistletoe plants high in the canopies of host trees. Some pathogens that could affect mistletoe might proliferate in congested growth that limits air circulation, but not where air circulates efficiently through sparse and exposed growth higher up. Some pathogens that proliferate in cool and damp situations are inhibited by drier and sunnier situations. Some pathogens are more likely to infect hosts that are closer to the ground. If rodents are taking mistletoe vegetation, they prefer the shelter of more congested lower growth, and avoid the vulnerability of more exposed higher growth.

Tree Monster

P71203Matthew McDermott got this picture, which was actually part of a video, of a tree burning from within during the devastating fires in Sonoma County last October 9. Many of us saw it in the news. It is actually not as uncommon as it would seem to be. Interior wood is more combustible, and sometimes already well aerated from decay, so can burn if exposed to fire through wounds or cavities, while the exterior of the same tree resists combustion. This is why there are so many big and healthy coastal redwoods with burned out hollow trunks. Of course, trees more commonly burn from the outside.

Once burned, charred wood is resistant to decay. Redwoods and cedars are resistant to decay anyway, so once charred and doubly resistant, they can stand for decades.

When my younger brother and I were little tykes, one such charred cedar lived at our maternal Grandparent’s summer house outside of Pioneer. That is, it ‘lived’ there before it got charred by a fire a very long time before the forest that was there in the early 1970s grew up around it. I never actually saw it living. It was VERY dead long before my time.

The problem was that my younger brother and I did not KNOW for certain that it was dead. It was a big charred trunk at the bottom of the clearing downhill from the house. We could see it from almost anywhere, except from inside or uphill of the house. It was ominous. It was creepy. It seemed to watch us. The rest of the pines, firs, cedars and everything else in the forest was so green and lush; but the big black carcass was always there.

We were not totally afraid though. Our Uncle Bill was there too. He was the greatest superhero in the entire universe! He was bigger and stronger than any man. He was tall enough to hang our swing in the big tall black oak tree. He had already protected us from the bats. (We did not know what bats were, but we knew they were scary.) He breathed smoke, and from a white and gold can with a picture of a waterfall and a horseshoe on it, he drank a magical potion that might have given him some of his superpowers. (My brother and I tried it, but it tasted icky.)

Uncle Bill had a chainsaw.

Uncle Bill started to cut the base of the big dead Tree Monster while everyone else watched from a distance. To us kids, it seemed to take a long time. Eventually, the Tree Monster wobbled a bit, and fell forward towards us, landing on the ground with a big dusty thud. The top broke off and slid a bit farther from the rest of the carcass, which only made the secondary death of the Tree Monster seem that much more violent. After a bit of a pause, my brother and I approached in disbelief. It was twice as dead as it was before! Uncle Bill had killed the dead Tree Monster!

We walked on top of the fallen carcass just to be certain, and found no signs of life. We inspected the low and wide dead stump and found only sawdust. When we looked back at where the Tree Monster had always been, we saw only lush green pine, fir and cedar foliage.

Through the following year, Uncle Bill cut and split the Tree Monster into firewood for my Grandmother to cook with. It kept us warm at night. Uncle Bill kept us safe.

What’s In A Name? Sometimes, Not Much.

P71209Newer developments are often named after what was destroyed to procure space for them. Writers and historians have been making that observation for decades.

There are obviously no remnants of a ranch in the McCarthy Ranch Marketplace in Milpitas. Heck, there are no little cornfields left in Milpitas, which is what ‘Milpitas’ means. Cherry Orchard Shopping Center in Sunnyvale? Give me a break! The Pruneyard Shopping Center in Campbell is no better.

I just happen to find the Pruneyard to be less objectionable than the others because it was built about the time I was born. It has been there as long as I can remember. My parents can remember when it was a drying yard for the prunes harvested in the surrounding orchards. I remember the last remnants of prune orchards, but by my time, there were not enough of them to justify the less lucrative use of real estate for drying, which could be done elsewhere.

The Pruneyard Towers are an office complex just to the west of the shopping center. The original Pruneyard Tower might still be the tallest building between San Francisco and Los Angeles. I know it was only a few decades ago. (Downtown San Jose has a ceiling on the heights of their skyscrapers because of the flightpath of the Mineta San Jose Airport.) I can remember as a kid, seeing the big black tower standing proudly off in the distance, beyond the blooming apricot orchards. When our parents were shopping there, and we got close to the Pruneyard Tower, we felt a bit more cosmopolitan, as if we lived in a big world class city. Back then, we had no idea that nearby San Jose was well on the way to becoming exactly that!

The shorter tower was added about 1976. The third and lowest of the three bigger towers was added in the 1990s. The late 1960s architecture of the shopping center is still prominent, but several original buildings have been rebuilt with modern architecture, and a few new buildings were added.

As much as I miss the orchards and the horticultural past of the Santa Clara Valley, I can not totally dislike the Pruneyard Shopping Center and the associated big towers. To my generation, they are also part of our history. They have been here as long as we have.

The one thing that I dislike about the Pruneyard Shopping Center is the name. It is a constant reminder that something that was such an important part of our local culture and history was destroyed so that it could be built. Nothing about the site is associated with the orchards, or drying yards or prunes, or anything of the sort.

Someone Got Payed For This?!

P71216See what happens when the plants in the garden are happy? They do pretty things. It is now halfway through December and this honeysuckle is still blooming nicely. The cool weather has inhibited bloom somewhat, but has not totally prevented it yet. By the end of winter, this honeysuckle will get pruned back so that it can regenerate new growth to bloom through next year.

This honeysuckle happens to be growing on a chain link fence behind a small group of apartments. Someone who lives in one of the apartments enjoys tending a few vegetables and flowers, but really does not put too much effort into the surrounding vines and shrubbery that obscure the view of the parking lot next door. That region of the garden gets only the maintenance that is required to keep it under control. The person who does it is no horticultural professional; merely someone who enjoys a bit of home gardening.

Horticultural professionals should know more about horticulture than someone who just enjoys growing a few vegetables and flowers after coming home from working at another profession. That is what they get payed for. That is why they are professionals. . . because it is their profession.

Right across Highway 9 from the homes with the honeysuckled fence is a pharmacy with a parking lot that is ‘maintained’ by ‘gardeners’. It looks like a parking lot. There are some nice young but shady elms that were recently pruned up for clearance by professional arborists who did a rather impressive job. Below the elms is a mixture of typical ‘low maintenance’ plants that are often found in parking lots, including lily-of-the-Nile, African iris, Oregon grape and Indian hawthorn, with a few dwarf Heavenly bamboo to add a slight bit of Japanese ethnic diversity into an otherwise African-American landscape.

Except for the elms and other young trees, none of the plants are exemplary. They are all tough plants that are resilient to the climate and abuse that they get in a pharmacy parking lot. Their main problem is the ‘maintenance’ performed by the ‘professional gardeners’. I could go on about this, but for now, I just want to describe what was done to the Heavenly bamboo.

It never really looks that good. It does not get a chance to. At least this time of year, this particular cultivar of Heavenly bamboo gets some rather nice color on it. Even if the foliage is mutilated and crowed from a lack of ‘proper’ pruning and an excess of ‘improper’ pruning, the reddish or burgundy color is pretty from a distance. At least, it would have been.

The ‘gardeners’ cut all the foliage off, just as it was beginning to color. Yep. It is all gone. The canes were cut into these tightly shorn but somehow awkwardly asymmetrical cylinders with angular edges around the circular and flat tops. How does one put that much effort into shearing something so tightly, and perfecting the flat top, without getting it symmetrical? Why put that much effort into ruining something just before the performance that it waited all year for, and just prior to the longest time of year before the weather warms enough for it to recover?

Shear abuse – with shears.

Perhaps those are questions that Rhody is pondering in the picture. Perhaps he just wants to leave a ‘message’ for the ‘gardeners’.P71216+

Poppies

P71213+K1Not just any poppies; California poppies, the state flower of California.

So why the picture of an old cinder block wall on the edge of an unkempt and weathered parking lot behind the old County Bank Building? Well, right there in the middle of the picture, where the lowest course of block meets the edge of the pavement are a few weeds, and some of these weeds are poppies showing how resilient they can be.

California poppies are opportunistic. They grow fast and bloom when they can. For most, that means that they bloom as the weather starts to warm up at the end of winter. For others in irrigated gardens, they can bloom in phases through summer. Some do their thing quickly as soon as they get a bit of moisture from the first autumn rains or even dew. They know what time of year it is, and that the weather will not likely get hot enough to cook them; so they bloom and throw their seed for another generation in a few more months, or maybe many months from now. They adapt. That is how they live on the edges of forests of the Santa Cruz Mountain, to interior valley chaparral, to the Mojave Desert. They are a remarkable specie.

Remember the poppies in the Wizard of Oz? There are several theories about what those poppies represent, and why the put Dorothy, the Cowardly Lion and Toto to sleep without affecting Scarecrow and TinMan. Duh, Scarecrow and TinMan do not breath. They can not inhale the narcotic produced by the poppies. Even if they did, they lack the physiology to be susceptible to opiates.

There is a significance to poppies blooming today, the same day I wrote about the gingko, on December 13; but this ain’t Oz.P71213+K2

Birthday

P71213This single yellow ginkgo leaf says a lot. It was found among the abundant cottonwood leaves on the broad walkway in Felton Covered Bridge Park (https://tonytomeo.wordpress.com/2017/12/02/felton-covered-bridge/). There are no ginkgo trees in the neighborhood that I am aware of. It must have come a long way to arrive here on the morning of December 13.

It really did not need to go through all the effort to get here. I need no help to remember the date. It is the birthday of a good friend who passed away last May.

Steven Michael Ralls is one of two friends I went to Oklahoma with late in 2012 (https://tonytomeo.wordpress.com/2017/11/19/oklahoma/). In the picture attached to my article about going to Oklahoma, there is a handsome gentleman to the left. That is me. The bronze guy in the middle was just standin’ on the corner in Winslow, Arizona. Steven is on the right. Gayle is on the sidewalk groping the bronze guy.

Steven did not know or care much about horticulture, but he knew ginkgo. It was his favorite tree; and it is the only tree that he remembered the botanical name for. There are a few gingko trees about Santa Cruz and elsewhere. He would sometimes point them out and exclaim, “Gingko biloba!”

I have not yet planted a ginkgo tree for Steven. At the spot under the Felton Covered Bridge where we scattered his ash, I planted a few canna seed that I brought back from Oklahoma, and some rooted cuttings of a pink brugmansia that I acquired during an outing with Steven to Santa Cruz. Neither grew enough to survive when the San Lorenzo River comes up this winter; so I will probably need to plant more.

Well, getting back to the single yellow ginkgo leaf. It says a lot. Today is December 13, the birthday of my good friend Steven.

Holy Guacamole!

P71202.jpgHorticulturists have a way of making all those long Latin names sound easy to pronounce. Lyanothamnus floribundus ‘Asplenifolius’ – Syzigium paniculatum – Metasequoia glyptostroboides. I do not know why proper pronunciation of their names is so important. They have no ears. They can not hear if we simply call them ‘Earl’. Even if they could hear, they would not respond.

Communication with other people is probably more important. Yet, we are so often unable to spell something as seemingly simple as the sound of a palm frond falling to the ground. Does it sound like “whoosh”, or “splat”, or some combination of both? What do the Santa Anna Winds sound like as they blow through a grove of Aleppo pines? What does a red flowering gum full of bees sound like?

Heck, Brent could not even tell me what an incident that he heard in his own backyard sounded like. As he came home from work and was getting out of the car in the driveway a few days ago, he heard in rapid succession, a loud ‘CRACK!’ followed immediately by a loud ‘WHOOSH!’ and a big ‘THUD!’ and ‘BANG!’. Well, I was sort of clear on all that, but it was the finale that was baffling him.

He said it sounded like someone dumping out a big bucked of tennis balls filled with something to make them heavy. I did not ask how he knew what that sounded like, or what the tennis balls were filled with, or why anyone would fill tennis balls with anything, or . . . He was obviously unsatisfied with that explanation, so said it sounded more like a whole bunch of billiard balls bouncing off of the bumpers all at the same time, without bumping into each other. Well, that is some pretty talented pool.

Okay, so it sounded like when you get into an elevator on the ninth floor of the Bank of America Tower, you know the big one downtown, and the bottom falls out of your big bag of ‘Eureka’ lemons somewhere between the fifth and fourth floors, and everyone is staring because it is noon thirty on Friday, and . . . well you know, . . . and then there was this . . . and . . . ain’t nobody got time for that!

Dude, just shut up! I get it.

Well, he went to the backyard to investigate. The source of the commotion was not immediately apparent from ground level. Everything seemed to be in order, maybe a bit sunnier, which might not have been noticed anywhere else after autumn . . . but this is Los Angeles. When Brent looked up to the deck on the flat roof of the office, it all became clear.

The big avocado tree in the neighbor’s garden dropped a big limb onto the deck. The last strange sound he heard was that of so many heavy avocados hitting the deck and scattering in every which direction, including down the wrought iron spiral stairs. All the patio furniture and cool potted plants up there got clobbered. Fortunately, there was no serious damage, and the avocado tree should be fine. Most of the fruit was in good condition. Only those that fell down the stairs were pulverized into lumpy guacamole.
