Six on Saturday: Deodar Cedar Migration

 

Deodar cedars that were featured in the gardening column about two weeks ago, https://tonytomeo.com/2018/11/27/deodar-cedar/ , live in a small grove adjacent to a building that I work out of. They need a bit of pruning for clearance from the roof, but are otherwise rather nice and healthy specimens.

They are also prolific. Quite a herd of seedlings is developing on the ground below. None of the individual seedlings are more than just a few years old, which suggests that the area was cleared of seedlings a few years ago. The area needs to be cleared of seedlings again, before they grow big enough to become a messy thicket.

Part of another landscape in another area happened to be in need of a few deodar cedars. There were two established specimens there already. They suit the situation so well that more are desired. However, new trees are expensive, and because there is no irrigation system in that particular site, they would need to be watered very regularly by hose until they get established.

Well, you can guess what happened. We pulled up several of the seedlings that needed to be pulled up anyway, and simply plugged them into the site where more deodar cedars are desired. It was done just prior to rain, so the relocated seedlings did not even need to be soaked in. They were pruned so that they would not desiccate so readily. We planted way more than necessary because there were plenty to spare, and also because we expect that several will not survive the process. We also expect that we will likely need to cut down a few later because, although some will not survive, too many probably will. Because they are just tiny seedlings, they will get established more efficiently than canned nursery stock, and will not be so sensitive to lapses of irrigation.

Although way more than necessary were relocated, they were not even a quarter of what was available in the original herd. More than three quarters of the herd remain available to be planted elsewhere. More will likely be relocated to other parts of other landscapes before the rainy season is half way finished. A few will be canned and put into the nursery. Whatever we do to them should be done in the early part of the rainy season to take advantage of the weather while they get established. We prefer to relocate the larger seedlings first, so that those that remain will be the smaller seedlings that will take longer to get too big to move if they must wait until next year to be relocated.

This is actually old technology, and how tree seedlings were pulled and plugged to enhance the production of woodlots since ancient history. While undesirable seedlings were pulled and discarded, more desirable seedlings that happened to be crowded around the parent trees were pulled up and plugged in more uniformly over a larger area.

Horridculture – Disdain For Bloom

P81212From the same landscape that, last autumn, was so dutifully deprived of its elegantly cascading rosemary and soon to be fiery autumn color of Boston ivy, https://tonytomeo.com/2017/11/05/serously/ , I procured these disturbing images of what results from of a serious disdain for flowering crabapple bloom. These trees were mentioned earlier in that article, but without such images. Similar victims were discussed last spring, https://tonytomeo.com/2018/03/07/the-good-the-bad-and-theyre-both-ugly/ and about a year ago https://tonytomeo.com/2017/12/06/sculpture/ .

The landscape where these trees live was actually rather well designed, and for a few years, had been well maintained. Seriously! The flowering crabapples were likely selected because they would not get tall enough to encroach into the utility easement above. There were pruned as much as necessary to prevent them from developing into a nasty thicket like young flowering crabapples typically do, but without significantly compromising the spectacular bloom. They really were spectacular!P81212+

About six years ago, a different crew of ‘gardeners’ was hired. It was obvious when it happened because the brutality to other features of the formerly well maintained landscape was so immediate. These flowering crabapples were somehow spared, but only temporarily. They were at their prime when they displayed exemplary bloom for the last time three springs ago. As these pictures indicate, they were hacked back two springs ago, just as the fat floral buds were showing bright pink color, and were about to pop open. All the buds and blooming stems that the trees had put so much work into were cut off and taken away, just days or maybe hours before the big show. The process was repeated in the same manner just prior to bloom last year. A scarce few twigs were somehow missed, and managed to bloom with a few blossoms that developed into the few fruits that can be seen in the second picture. I can not explain why the hacking was done earlier this year. Nor can I explain why a bit more of the twiggy growth remains. Did the ‘gardeners’ leave it for a tiny bit of bloom, or were they just lazy with their mutilation. It does not matter. As long as these trees get hacked like this, they are ruined. The client pays the ‘gardeners’ to do this.

Now, these trees could only be salvaged by renovation. This would involve pollarding, which would remove the tangles of gnarled stubs, but would leave horridly stubbed limbs to start the regeneration process. The trees would be just as deprived of bloom for the first year, but would at least be able to compartmentalize (heal) the wounds on the cleanly stubbed limbs. The secondary growth would need to be very meticulously and systematically groomed and pruned for many years to replace the canopy. It is possible, but would involve more work than even a good horticulturist or arborist would want to devote to the project.P81212++

Rhus diversiloba / Toxicodendron diversilobum

P81209This would be a good topic for one of my rants on Wednesday, except that it is too silly for that.

Many years ago, before I started writing my gardening column for our local newspapers, my colleague Brent and I used to exchange funny newspaper gardening articles. Some were obviously not written for local climates. Some were just very inaccurate. Back then, it was done by mail, so the articles were added to anything that we happened to be sending to each other at the time. If I sent him some seeds, I would add an article or a few from the San Jose Mercury News. If he sent my cuttings, he would add an article or a few from the Los Angeles Times. They eventually became the inspiration for my gardening column, when Brent and others told me that rather than making fun of the inaccuracies of the articles, I should provide accurate articles.

One of the silliest that Brent sent to me was an otherwise well written article about star jasmine. Most of the information about it was accurate, until it got to describing the colors of the exclusively white bloom. The article explained that star jasmine bloomed in vivid shades or blue, purple, red, orange and yellow; just about every color except for white!

Well, I topped that with an article about protecting Japanese maples from theft, which sounded crazy even before reading the article. There were three recommendations. The first was to surround the subject Japanese maple with razor wire. Ah, the ambiance! The second recommendation was to dig a hole about as big as a trash can and fill it with concrete with a curved piece of rebar to make an enclosed loop on top, and then chain the subject Japanese maple to it. How about we just do without a Japanese maple in the front yard in a neighborhood where we expect it to get stolen. The third recommendation was to plant poison oak around the subject Japanese maple. Yes, good old fashioned poison oak, Rhus diversiloba, which is also known by the more descriptive Latin name of Toxicodendron diversilobum, and commonly available at . . . . some nursery . . . . somewhere. . . . You know, one of those . . . . garden centers . . . . or something.

Silly? Yes! What is sillier is that poison oak really IS available from certain nurseries that sell native specie! What is even SILLIER than that incredible degree of SILLINESS is that one of the so-called landscape companies that I worked for in about 2006 actually procured some for habitat restoration outside of, but adjacent to a newly landscaped area on the banks of where the Guadalupe River flows through San Jose. Poison oak and other native vegetation needed to be eradicated for the installation of the new poison oak and associated irrigation system, because nothing is more natural than supplemental irrigation! Then, the ‘gardeners’ had to conduct regularly scheduled weed abatement so that poison oak growing from seed tossed by the pre-existing poison oak did not grow up and compete with the new poison oak in the new ‘natural’ ‘landscape’. We certainly would not want poison oak taking over the poison oak.

Okay, this is not Wednesday, so I will finish this rant.

Poison oak happens to provide some of the best orange and red autumn foliar color in our region where almost all of such color is simple yellow. Where it is out of the way and not bothering anyone, it is sometimes left to climb high into trees, where it colors almost as well as flowering pear. Yes, it is pretty, but I will not be planting any of it.P81209+

Tufts

P81208KKThe tufts of small branches that so often develop where limbs were pruned from the trunks of a coast live oaks are sometimes referred to as ‘tumbleweeds’. They are about the same size as an average tumbleweed. By the time the get any larger, most of the smaller stems have subordinated and died out, leaving only a few more defined dominant stems, which will continue the process until even fewer or a single new branch dominates. Such tumbleweeds, as well as stems that originated from such growth, are weakly attached to the main trunks. They often get pruned off for the same reason that the limbs that were there before got pruned off, or because they are expected to be weakly attached. If they remain long enough, they can of course develop into new limbs.

Tufts of the same sort of growth on sycamores or other deciduous trees are known more simply as . . . ‘tufts’ I bet you didn’t see that coming. They can get much bigger than tumbleweeds before they develop much distinction between the dominant and subordinate growth. Because tuft growth is innately vigorous, the leaves are bigger and coarser. Then, when the rest of the deciduous trees that produce them defoliate in autumn, the tufts retain their green foliage until it gets ruined by frost.

This big sycamore dropped its top over summer. https://tonytomeo.com/2018/07/14/nature-is-messy/ The tufts developed on the big trunks that became exposed to sunlight by the loss of the upper canopy above. The tree will naturally try to replace its top, but will also naturally be even more disfigured and structurally deficient than it already was. As the tufts develop into limbs, and the limbs get heavy with foliage, they will be very likely to break away and fall. As unpleasant as all that sounds, it is quite natural for such a mature sycamore who is so old that he just doesn’t care who gets offended anymore.

Six on Saturday: Too Much Autumn Color IV – Uncategorized Exotics

 

These are the last six of the twenty four pictures of autumn foliar color that I got before the rain knocked so much of the foliage to the ground more than a week ago. #2 is the only picture of foliage that is on the ground instead of still suspended on the stems that produced it. The fallen birch leaves were just too pretty on the stone wall to not get a picture of them.

1. Japanese maple is not my favorite species, but it does have certain attributes. There happen to be several at work just because they happen to work well there. Some that do not typically develop good color got remarkably colorful this year. I believe that this particular Japanese maple is the common ‘Bloodgood’. It had been dark reddish bronze through summer, and then turned brighter red for autumn.P81222

2. European white birch is grown for the elegant white trunks that contrast so nicely against the deep green of the redwoods. This autumn foliar color, although brief, is an added bonus. These trees were already starting to defoliate before the rain.P81222+

3. Hydrangea is not known for autumn foliar color, and as you can see, turns only pale yellow. Yet, it is striking in the shade, and contrasts nicely with the rich green of redwood and English ivy foliage.P81222++

4. Spirea is likewise not grown for autumn foliar color, or at least no so much in our mild climate. There are more than a dozen of them here, and none are doing very well. They will get cut back and groomed now that they are bare. I do not know what cultivar this particular spirea is.P81222+++

5. Golden weeping willow was not only golden with autumn foliar color, but is still golden with the yellow bark on the twigs. So far, I am not too impressed with the yellow twigs. It is still a small tree, and growing in a mild climate that may not stimulate much color. Regardless, I happen to like weeping willows. This one happens to be in a swampy spot where it is quite happy.P81222++++

6. Bald cypress is rare here, but there happens to be two at work. One was supposed to be a dawn redwood, but was obviously mislabeled. Fortunately, it just happened to be planted on the bank of a small creek where it gets plenty of water. The other was planted in an area that is too swampy for other trees. Both are doing quite well. When they defoliated, they covered the ground with finely textured needles that would have been impossible to rake up.P81222+++++

Six on Saturday: Too Much Autumn Color III – Cherries, Berries, Plums, Apples, . . . & Ginkgo

 

Autumn foliar color, fall color, autumn leaves or whatever you know it as; there was too much of it to fit into just six pictures. That is why I submitted two ‘Six on Saturday’ posts last week, and why this one is number ‘III’, and why there will be a number ‘IV’ right afterward. Only one reader expressed concern that submitting two posts to ‘Six on Saturday’ on the same Saturday is a violation of the rules, but I got the impression that even he did not mind. These pictures, as well as the next six, were actually taken more than a week ago, which might violate another rule. If you are seeing them now, I have not yet been prosecuted, and compelled to delete them. Much of the foliage was knocked to the ground by rain since the pictures were taken. The apple tree #4 was pruned back severely, and is now completely defoliate. The title ‘Cherries, Berries, Plums, Apples, . . . & Ginkgo’ implies that all but one are fruit trees; but they aren’t. Well, you can see what I mean.

1. Yoshino flowering cherry, which I know as ‘Akebono’, just might be the most traditional of the Japanese flowering cherries in America. It is the classic cherry blossom tree around Washington D. C.. As flashy as the bloom is, it is sterile; so the trees are fruitless. You can not see it, but the home in the background is of classic Early American architecture. It is a family home, so is too big for my taste. It would otherwise be my favorite home in the neighborhood.P8215

2. Kwanzan flowering cherry is the second most popular flowering cherry in our region. The big pink double flowers are a bit too garish for my taste, but they really are flashy! Like the Yoshino cherry, the Kwanzan cherry is fruitless.P8215+

3. American plum is not native here, but naturalized. It was and probably still is a common understock for quite a few of the stone fruits. It often grows from the roots of a stone fruit tree that got cut down to the ground. It makes small tart plums that are not much bigger than fat cherries, but not many of us use them for anything. Garden varieties of plum and cherry are naturally more desirable. I Intend to use American plum for jam, but I always get out to pick them after they have fallen to the ground and gone bad. You may have noticed that the first three subjects are of the same genus, Prunus.P8215++

4. Apple happens to do very well in our region. The old apple trees on the farm are remnants of an old orchard. Others in the neighborhood are from old farms. This one is on the edge of a sidewalk where it was not likely planted intentionally. It likely grew from a seed from a discarded apple core. It does happen to make apples, but they are no good. I just cut this tree back severely. If the apples are still no good next year, the tree might get cut down.P8215+++

5. Ginkgo is an ornamental tree here. Because those of us who do not want the fruit find the stinky aroma and mess to be objectionable, garden varieties are all male, and therefore fruitless. However, in some cultures, ginkgo is grown both for fruit, and for the nuts within the fruit. There are a few female trees in older neighborhoods here. They were grown from seed before all male garden varieties were developed. Back then, there was no way to determine the gender of a ginkgo tree until it started to develop fruit . . . or hopefully didn’t.P8215++++

6. Barberry is strictly ornamental. I have never actually seen a bar’berry’ fruit. This particular unknown cultivar happens to be bronzed, with very dark foliage that turns bright yellow and orange for autumn. It is very thorny!P8215+++++

Horridculture – Lack Of Planning

P81128+This is a recycled picture that still annoys me. There was another that I did not want to use because it happens to be from a landscape that I sometimes work in.
The picture that I did not use shows a variety of annuals in a half wine barrel that is set on cobble stone that fills a square that is about five feet by five feet that was cut out of an asphalt paved area.
So:
The area was paved to function as a patio.
A square was cut into the pavement perhaps because there was too much pavement.
The square was filled with stone because there was too much exposed soil where there should have been pavement.
A half wine barrel of various annuals was installed on top of the stone as if a square filled with stone was not adequately in the way.\
The half wine barrel and stone should be removed so that the are can be paved as usable patio space. . . like it had originally been.
It reminds me of a monologue by the renowned comedian, Bill Cosby. He discussed the small compartment that is designed to keep butter from getting too cold within a refrigerator that is designed to keep food cold, within the home that is heated to keep the interior from getting too cold.
Now, back to the picture above. It annoys me even more because it is not the result of a series of mistakes by several different volunteers working in the landscape that I did not post a picture of. It was done by so-called ‘professionals’, like those I briefly worked for a few years ago.
The area was paved. I might add that it was paved quite well. Then, either because there was too much pavement, or because someone wanted to sell more junk, potted plants and the associated irrigation system were installed onto the pavement, so that the affected portion of pavement is now useless.
How does this makes sense? It should have been done properly when the pavement was installed only a few years ago. I would guess from looking at it that the pavement was done properly, but someone just wanted to sell more infrastructure.
The bigger urn in the foreground is planted with pink jasmine on a trellis. I explained the problem with the vine not getting released from its bindings last week. https://tonytomeo.com/2018/11/28/horridculture-well-done-stakes-are-rare/ Not only does a bundled thicket of stems remain in the middle, but all the new growth is crowded on top of the trellis because the landscape ‘professionals’ planted a big vine on a tiny trellis, and then neglect to maintain it. What is the point of a trellised vine in the first place? I mean, what does it ‘do’? Wouldn’t something shrubbier or a cascading perennial have been more appropriate? Do we really want to see the bare soil and accumulated cigarette butts below the vine? What about the landscape behind the potted plants? Why obscure that? Why create more obstacles for those who sweep or blow debris from the area.
Just look at all the pointless infrastructure in this useless space. Rather than a nice well designed landscape adjacent to clean and usable pavement, we have pointless potted plants cluttering the area, leaking water that stains the now useless pavement, and just getting in the way!

The Humongous Fungus Among Us

04Is this Armillaria mellea, the dreaded oak root rot fungus? I really do not know. All the elements are here. The stump is that of a coast live oak. Bellow the stump there are the remains of roots. Those necrotic roots are undoubtedly decomposing as a result of rot. That rot is undoubtedly associated with this fungus. Furthermore, it fits the description of oak root rot fungus. The toasted spots were probably caused by weathering as the mushrooms started to develop while the weather was still warm and dry.

Now that the soil and rotting wood are damp from rain, this fungus is really proliferating. The individual mushrooms within the soccer ball sized mass were only about as big as those at the lower left margin of the picture just prior to the rain. They do not last long, and might become gooey black slop after only a few sunny days. The stump may continue to rot for a few more years. It is out of the way, so there is not need to get rid of it.

It annoys me when landscape professionals tell me that a particular spot in the region has oak root rot fungus. Of course it does. It is everywhere. It is quite natural here.

Oak root rot fungus is justifiably dreaded. It can easily kill the most majestic oaks that have survived for centuries.

However, most of the problems with oak root rot fungus in landscape situations are caused by supplemental irrigation and other gardening techniques. Oaks that have survived on natural seasonal rainfall for centuries are much more susceptible to rot if their roots are kept continually moist by the irrigation needed to sustain other plants added around them. Roots that get severed for the installation of pavement or building foundations are likewise much more susceptible to rot, particularly in spots where drainage from roofs or paved surfaces enhances soil moisture.

For this particular pathogen, gardening is more often the problem.

Crape Myrtle Finale

P81201KIt is certainly not my favorite small tree. Actually, in most situations, I rather dislike it, which is why I sometimes accidentally spell it without the first ‘e’. It is a cop out; a micro tree that too often ends up where a larger and more respectable tree would be more appropriate. They are not shade trees. They are not not big enough for freeway landscapes or to be street trees on wide boulevards. They are not immune to diseases and insect infestations; and they commonly drop honeydew from aphid or scale infestation, and lose their bloom to powdery mildew. They are not ‘low-maintenance’, and really should be pruned more than they are, but will get you in trouble with the neighbors if you prune them as aggressively as they should be pruned.
They are popular because of their potential for remarkably flashy bloom, and because they do not get big enough to damage the sidewalks and curbs that they are so often planted next to. ‘Gardeners’ like them because they survive their neglect. That is no long list of attributes; but there is one more.
FALL COLOR! On a bad year, they merely turn bright yellow. This year, some are this exquisitely bright orange with a slight red blush. The various cultivars display various colors, so some are more colorful than others. They are also on different schedules, so the most colorful are not necessarily the most colorful every year. Those that colored early are already bare, but could be the most colorful next year if the weather turns cold early. A bunch in town that are also defoliating as fast as they color because of the recent rain, could be the most colorful next year if rain is delayed later than it was this year.P81201K+

Six on Saturday: Too Much Autumn Color II – Natives & Exotics

 

Now we have a bit more variety than the last batch of six.

Red stem dogwood of the first and second pictures is the only species that is locally native. The California currant of the fourth picture, and the California black walnut of the fifth picture are both as native to California as the names imply, but are not native locally. The flowering dogwood of the third picture is from Eastern North America. You can guess the origin of the Chinese wisteria of the sixth picture, which happens to be the only vine represented in all four groups of six pictures.

The first three of the six pictures, or half, are of dogwood. The first two pictures are the only two in all four groups of six pictures that are the same species, namely red stem dogwood. Both were posted just to demonstrate that red twig dogwood, which typically turns only pale yellow like the foliage of the first picture, can develop a bit of red foliage like that of the second picture, if conditions are just so. Both the red stem dogwood of the second picture, and the flowering dogwood of the third picture, are the first two examples of red foliage from my four groups of six pictures. In the next two groups of six pictures, there is only one other example of bright red foliage, as well as an example of brown foliage, and an example of irregularly bronzed orange foliage. Those are topics for next week.
