Leaves Leave

P80104+I do not know where they went. There are plenty that are not worth getting pictures of, but the pretty and colorful ones that I wanted to show off in the ‘Six on Saturday’ post are gone. I suppose that they are still out there. They just are not as pretty and colorful as they were earlier.

Pistache leaves deteriorate quickly. They were very colorful while still in the trees, but were not much to look at by the time they were on the ground.

Ginkgo colored well too, but after I got that one picture of the single leaf, I could find no others. The tree that sent that leaf is not in the neighborhood. ( https://tonytomeo.wordpress.com/?s=birthday )

I suppose that I could have gotten a good picture of a colorful sweetgum leaf. I just did not bother with them. Nor did I bother with flowering pear.

California sycamore does not color very well. It was a bit more colorful this year than it typically is, with a bit more orange in the hazy brownish tan, but still nothing too flashy. The leaves are not very pretty anyway. They are sort of big and flabby . . . and awkwardly asymmetrical. I mean, every leaf seems to be disfigured. They are not neat and distinguished like maple leaves are. I took this picture of a deteriorating leaf of a California sycamore because it was more interesting than colorful. There is barely any gold or orange left in it. Gray blotches left from anthracnose or powdery mildew certainly do not add much to the color. This leaf is unusually big because it came from a vigorous watersprout.

The heart shaped cottonwood leaf is still somewhat gold, with gray around the edges. Cottonwoods actually color nicely in other climates. Local trees defoliated faster than the foliage could turn yellow. They really did not like the late weather this year.P80104++

Earthquake?

https://i0.wp.com/www.rms.com/blog/wp-content/uploads/2013/10/HaywardFault.jpg

Just about twenty minutes to three, there was a minor earthquake that is now rated at 4.7 near Berkeley. That can change with updates of course. I am wide awake and annoyed. This was not on my itinerary. What is scary is that the Calaveras Fault has been moving lately near San Jose. We got our first good storm yesterday, and some area around here has burned. Bare ground, rain and earthquakes do not go together well. Okay, so this has nothing to do with gardening.

Update: It is now about half a day later and the earthquake was downgraded to a 4.4, and was located on the Hayward Fault, not the Calaveras Fault, in Berkeley near Oakland. It occurred at 2:39 a.m..

‘Rain’

P80103+Like something from an old fashioned science fiction movie, this anomaly appeared in a roadway overnight. There are several more in other roadways and elsewhere about town. They are quite wet. In fact, they are composed almost completely of water. What is even weirder is that the water that they are composed of actually fell mysteriously from the sky overnight as many countless droplets all over town! Many of these droplets migrated into low spots such as this one to form what we now see in this picture.

People in other climates where these mysterious droplets are not so rare might be familiar with this sort of phenomenon. The droplets of water are known as ‘rain’. They precipitate out of the atmosphere as it cools and can not contain as much water vapor as it did when it was warmer. As the droplets migrate into low spots in roadways and anywhere else, they accumulate into these collective herds of droplets known as ‘puddles’. Many of the droplets continue to migrate as huge herds known as ‘creeks’, and even bigger creeks known as ‘rivers’. Some of these creeks and rivers migrate into really big puddles known as ‘ponds’, and even bigger ponds known as ‘lakes’. Sadly, not all of the droplets can be accommodated in ponds and lakes, so many continue to migrate out into the ‘ocean’, which is that really big pond full of salty water to the west that we are all familiar with.

Hopefully, some of these droplets of rain will stay around for a while and provide water for the plants in our gardens and forests. Ideally, some will burrow into the ground and stay for a very long time, and maybe even migrate into the aquifer to hibernate. In our climate, particularly after such a long and dry summer and autumn, these strange droplets of rain are very welcome to stay as long as they want to.

New Year & Old School

P80101Little kids were allowed to walk to school back in the early 1970s. The youngest had to walk with older siblings or neighbors who made them look both ways and hold hands to cross the streets, and stay back from the roadway. Once through the open gate into the schoolyard, younger kids could leave their slightly older chaperones to meet up with their friends and eventually go to their respective classrooms.

It is scary to think of how carefree we were back then.

The east side of our schoolyard was hedged with alternating Monterey pines and Monterey cypress, with a few random deodar cedars, redwoods and even a California pepper tree and a Canary Island date palm just inside the hedge. The random trees were somewhat mature, so were likely remnants of a landscape of a home that was on the site before the school was built there. The hedge was probably installed shortly after the school was built. It was that sort of shabby bad hedge that was common back in the mid 1950s. Nowadays, we know that neither the pines nor the cypress should have been shorn. The cypress could have made a nice hedge without the pines, but even back then, no one wanted to handle the sticky mess.

By 1972 and 1973, when the hedge was less than twenty years old, it was already beginning to assume a natural form. Only limbs that tried to grow through the fence on the outside, or too far into the schoolyard on the inside, got pruned back. No one was trying to keep it shorn. It was quite a thicket; perfect for a new kindergartener to hide out in.

Yes, I am speaking from experience. On my way to school one morning, I decided that I wanted to take a nap; so I weaseled my way in between the first cypress tree and the outer cyclone fence in order to do so. I somehow got past the cypress and found a nice soft spot on the thick layer of pine needles under the first pine, and promptly fell asleep.

Needless to say, my kindergarten teacher was very concerned when I did not get to school on time. Eventually, I woke up and emerged from my den to find the schoolyard empty. By the time I got to school all dusty and dirty and sticky with pine and cypress pitch, my teacher was really quite panicked. I did not understand why. I just wanted to take a nap.

Well, those first two trees in the hedge were the first Monterey cypress and Monterey pine I ever met. Sadly, through the 1980s and 1990s, almost all of the trees in the hedge succumbed to the variety of insect and disease pathogens that were so common in those two specie through that time. (New pathogens moved into the area and proliferated because these two host specie were so common at the time.) I can remember seeing that first cypress in the hedge dying like so many of the others in the hedge had died already.

While the trees were dying over the years, the school and adjacent neighborhoods were annexed into the city. The school was sold and rebuild at a private school. The schoolyard got a bigger fancy fence without gates. Students could only enter through a main entrance at the front of the school. A nice hedge row of redwoods was planted on the fence line where the pines and cypress had been. Then, a saran screen was affixed to the fence to obscure the view of the schoolyard and trees from the outside.

More recently, I had to go back to the old school to inspect a tree, and provide the arborist report needed to procure a removal permit from the city that the school is now annexed to.

Getting into the school was not nearly as easy as it was when I was in kindergarten. I had to go to the office, sign in with all my credentials and contact information, and wait for both a chaperone and a property manager to take me directly to the tree while also avoiding the pale protected children that now infest the old school. There were surveillance cameras everywhere, and security guards at the gates.

It is scary to think of how scared children are taught to be now.

Anyway, as you can guess, the tree that I was expected to condemn was that first Monterey pine that I had ever met, the second tree after the cypress in the original hedge.

There was a problem. I could find no problem with the tree. I mean, there was nothing wrong with it. It was healthy, stable and exhibited no symptoms associated with structural deficiency; which was weird considering what it had experienced through most of its life. When I asked the property manager what the problem was with the tree, he told me that it did not ‘fit in’ with the nice uniform row of redwoods. In other words, it did not conform. Oh. Ummmm. Well, that is no justification for removal of such a nice healthy Monterey pine that benefits the whole neighborhood. You can imagine how pleasurable it was to tell him that.

Now, I am the sort that believes that tree preservation ordinances are too restrictive. They actually prompt some people to cut trees down before they get big enough to be protected! Besides, such ordinances interfere with the rights of those who own property. There are certainly big and prominent trees that are worth protecting. This pine was not one of those. Yet, for once in my career, I was pleased that such an unimportant tree was protected by silly overprotective ordinances.

The property manager was annoyed that I could not do as he requested. There was no report condemning the tree. The tree service company that sent me out there for the inspection got no work out of the deal. Apparently, no other arborist would condemn the tree either.

Now that you are reading this, it is 2018, another New Year more than six decades after that nonconforming Monterey pine was planted where it still lives at the Old School.

Arboriculture: Deep Space Nine

P71231The “Poly” in Cal Poly is for “Polytechnic”, as in there are multiple schools within “California Polytechnic State University” at San Luis Obispo. There were seven school when I was there between 1985 and 1990. I was a student of the “School of Agriculture”. “Horticulture” was my “Major”, or major realm of study within this school. Within this major, I selected “Floriculture and Nursery Production” as my “Concentration” of study. That certainly is a lot of quotation marks.

While majoring in horticulture at Cal Poly, I studied with students whose concentrations of study were within “Landscaping” or “Floral Design”. Withing the School of Agriculture, we studied with students who majored in “Crop Science” or “Animal Science” and so on. Like horticulture, each of those other majors was divided into other concentrations.

Then there were all those students of the other six schools, which I will not even get into because I am wearing out the quotation mark key.

In the summer of 1988, while many of my colleagues were going to Australia, New Zealand or South Africa for their internships, I stayed right here in California, and took a job with a Lee’s Tree Surgeons in Saratoga. My colleagues thought that was a bad idea. Not only was that sort of internship for those in the landscaping concentration, but it was for the lowliest among them. They climbed trees and used chain saws and ropes and such. They were primitive. They were barbaric. They were not like us.

As it turned out, I was not like them. Fortunately, they did not mind. They took very good care of me, and trained me as best they could about arboriculture in the three months I was with them. They realized pretty quickly that I was not a good candidate for the job they gave me, but made accommodations for me. Although I was never proficient at climbing, and was not really good for much at all during that summer, I later went back to work for some of them, and eventually became a somewhat proficient groundsman; but that is another story for another time.

In my fourth year at Cal Poly, San Luis Obispo, after my internship with Lee’s Tree Surgeons, I relocated from my semi-rural home back into town, and lived in a big apartments with three roommates. We made a tradition of watching “Star Trek: the Next Generation” on television. One of the roommates, who is now a very respected professor at Cal Poly, made cornbread for the weekly event. Although I did not continue the tradition after we all graduated and went our separate ways, I did sometimes watch “Star Trek: Deep Space Nine” when it came out a few years later. I really need to stop with the quotation marks.

In Star Trek: Deep Space Nine, I liked the concept of so many different species living together in an society in which it was very necessary to make accommodations for those who are different. Everyone needed to respect everyone else. Some even learned to appreciate the differences. Even the bad guys had redeeming and very often likeable traits.

In my career, I am primarily a nurseryman. That means I grow things. Other horticultural professionals might compare my people to the Vulcans. They think that we are too uptight, efficient and plain to be much fun. Factory growers (who work for the big corporate growers) would be more like Romulans, and are therefore less dedicated to what is right and logical if it is to their disadvantage. Some of the better artistic landscape designers are likened to the Bajorans. Unscrupulous maintenance gardeners who will do what they must to make a buck are comparable to the Ferengi. Some of them work for the larger and imperialistic Cardassian landscape corporations.

Arborists are the most excellent of all; or perhaps the second most excellent after Vulcan nurseryman. They are like the Klingons; honorable, noble, independent, passionate and boisterous! I can understand why my colleagues think of them as barbaric and primitive, but I also believe that my colleagues should be more accommodating. When I consider what arborists must have though of me what I did my internship, I realize that it must not have been easy for them to accommodate me. Yet, they did, and in the most excellent way. They still respect that I have my own career in my own world, but to this day, thirty light years later, they are still pleased to invite me to their world.

Very Bad Houseplants

P71230Just because it ‘can’ be grown as a houseplant does not meant that it ‘should’ be. That is a lesson that Brent and I never learned in college. He and I were roommates in the dorms at Cal Poly in San Luis Obispo, which, as you can imagine, was a problem. Our room on the top floor of Fremont Hall was known as the Jungle Room. It was so stuffed full of weird houseplants, as well as a few plants that had no business inside. We had a blue gum eucalyptus bent up against the ceiling, an espaliered Southern magnolia, a Monterey cypress, and a herd of camellias that we rescued from a compost pile on campus.

After college, our own homes were no better. Because my dining room was rather small, Brent gave me tall weeping figs that had unobtrusively bare trunks down low, and plenty of fluffy foliage pressed up against the ceiling; a technique we did not quite perfect with our Jungle Room blue gum. I had a giant yucca in the guest suite, a redwood in my bedroom, king palms in the parlor, and a lemon gum eucalyptus over my desk in the office. The bathroom was the worst, with pothos and Algerian ivy hanging over the shower curtain, and billbergias up over the shower. A pair of small birds nested in the billbergias, and before I realized that they were there and evicted them, they started a family!

At least Brent kept most of his plants outside where they belong. The staghorn ferns grab onto the walls when they get the chance. Wisteria vines grab onto anything else. The flame vine climbed up the chimney (appropriately), and before Brent knew it, had sneakily spread to the opposite side of the parapet roof! Then there was the giant timber bamboo. Yes, that is what I said; giant timber bamboo. I know what you are thinking right now, so there is no need to say it.

There is a narrow space between north side of Brent’s home and the concrete driveway next door. It is almost three feet wide. Brent though that if he planted the bamboo there, it would not get to the other side of the driveway. He was actually correct.

Did I ever mention how vain Brent is? Well, that is another topic for another time. I will say for now that he has more clothes than his teenaged daughter Grace. A lot more. They do not all fit in his big closet. He hangs some of his longer coats that he does not need very often in Grace’s much smaller closet. One day, he was reaching around the clutter that is common in a teenaged girl’s room, and groping for one of his coats in Grace’s closet, when he grabbed a hold of something that should not have been there. He was not certain what it was at first, but when he found his coat and pulled it out, a few dried bamboo leaves came with it and fell onto the floor!

The bamboo did not even try to go under the neighbor’s driveway. Instead, it went under the foundation of the house. Where it came up, it had nowhere to go, so somehow weaseled in next to a water pipe, and followed it up behind the bathroom washbasin. Once inside, it somehow weaseled past a valve access panel behind Grace’s closet, and straight up to the ceiling. What is even funnier is that Grace knew it was there, but figured that it was just another one of Brent’s crazy landscaping ideas!

Just in case you are wondering, giant timber bamboo is a very bad houseplant!

The bamboo is gone now. It got so tall that the wind would blow it against the terracotta tiles on top of the parapet wall. Also, the foliar litter was too messy on the parapet roof and the neighbor’s driveway. It did not contribute much to the landscape anyway, and shaded only a driveway that is seldom used.

Merry Christmas!

P71225Does anyone else think that it is odd that Baby Jesus got only some frankincense, myrrh and gold for His first Christmas? I mean, it was the first Christmas ever, and that was the best that anyone could do? Well, maybe those gifts were something important back then. Maybe it was a good heap of gold. It just seems to me that three ‘wise’ men could have procured better gifts. More than two thousand years later, some of us are disappointed if we do not get a new Lexus on Jesus’ birthday, after He got only frankincense, myrrh and gold. (Get your own birthday!)

Although I do not remember my first Christmas, I know that my parents and others got excellent Christmas gifts for us kids when we were young. Our stocking that hung over the fireplace were filled with a mix of nuts, mandarin oranges, cellophane wrapped hard candies and small wooden toys. This is a tradition that dates back to a time when citrus fruits and certain nuts were something fancy that needed to be imported to Northern Europe from Mediterranean regions.

Of course, citrus grows quite well in our region, and almonds and walnuts still grew in the last remnants of local orchards. Our great grandparents had two mature English walnut trees in their gardens. Only pecans and hazelnuts were exotic. I happened to like pecans because they are from Oklahoma. (I did not know where or what Oklahoma was back then, but I knew it was an excellent place.) Hazelnuts were from Vermont, which is twice as far away as Oklahoma is, if you can believe that!

The gifts under the Christmas trees were even more excellent! One year, I got packets of seed for a warm season vegetable garden the following spring. There were seed for pole beans, corn, pumpkins, cucumbers and zucchini. (The cabbage incident that I will write about later happened in the cool season garden the following autumn.) Under the Christmas tree at my grandparents house, I got all the gardening tools that I would need in my garden, including a small shovel, garden rake, leaf rake and hoe. But wait, there’s more! Under the Christmas tree at my great grandparent’s house, I got flower seed for bachelor button, alyssum and a few others, as well as bare root rhubarb plants (from my great grandfather’s rhubarb that he had been growing longer than anyone can remember). I had already learned about seed from my first nasturtiums (https://tonytomeo.wordpress.com/2017/10/07/dago-pansies/), so I could not have been more pleased with my cache of gifts.

For later Christmases, and also birthdays, I got all sort of other things that were much more excellent than frankincense, myrrh and gold, including an incense cedar (how appropriate) that my grandparents brought back from the summer house near Pioneer, and a young ‘Meyer’ lemon tree. My Radio Flyer wagon was the biggest and most excellent in the neighborhood, and was more than sufficient to haul all my gear around the garden with. My big watering can was a bit too big, and was too heavy for me to move when it was full of water.

I would not say that these gifts were extravagant. They were just . . . okay, so they were extravagant. It was a long time ago. Unfortunately, my parents figured out that their gifts were somewhat excessive just prior to buying me the Buick I wanted. The wagon is still around. My mother uses it to bring in firewood. She also uses the little shovel to clean ash from the stove.

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.
