Many municipalities enforce tree preservation ordinances. Whether we agree with them or not, these ordinances are designed to preserve significant trees that are assets to the community. For the greater good, local governments have made it their business to limit what we can do with our own trees on our own properties. There are many advantages. There are many disadvantages. We arborists see it all.
Street trees, by general definition, are those that are close enough to a curb to shade a roadway and parked cars. In suburban and urban neighborhoods, many street trees are within parkstrips, which are the narrow spaces between curbs and sidewalks.
Neighborhoods of tract homes are typically outfitted with uniform trees of only one or two cultivars, that were all installed at the same time, as the homes were completed. Some neighborhoods of homes that were built individually are also outfitted with conforming street trees that were installed as parcels were subdivided. Most of such trees were installed as contingencies to development of the sites.
Since such trees were required by the associated municipality, they used to be maintained as such, just like any other trees in parks, medians or other public spaces. Municipalities that lacked tree preservation ordinances protected street trees as the public property that they were considered to be. Those who owned homes that were outfitted with such trees were not allowed to cut them down or even prune them without permission.
In some ways that sounds like a pretty good deal. The problem was that for many municipalities, it did not last. As the maintenance of maturing trees continually became more expensive, resources that used to be allocated for the maintenance of street trees were diverted to other projects. Although they do not like to talk about it, many municipalities no longer maintain their street trees, or do so selectively.
The aging trees remain. Many get cut down secretly by property owners who get frustrated by the lack of maintenance. Most are well maintained, but at the expense of those who own the properties where such trees live.
Most of us probably do not mind paying to have our street trees pruned when necessary. However, it is frustrating for those of us who must contend with some of the more problematic trees, and trees that are unusually expensive to maintain. Furthermore, property owners must assume the expense of repairing sidewalks, curbs and driveways that are damaged by roots, as well as damage to anything that limbs fall onto.
Municipalities that once required the installation of street trees, and that should still be encouraging residents to protect and appreciate their urban forests, are no longer able to assume the liability associated with street trees.
These pictures show two large limbs that fell from a big Canary Island pine onto two parked cars in Leimert Park of Los Angeles. A concerned citizen had contacted the Los Angeles Department of Public Works a few times about the tree, because one of the two fallen limbs had broken off quite some time ago, and was entangled with the other limb that broke and fell shortly before these pictures were taken on Sunday morning.
Good Weeds
We don’t put much effort into our compost piles. In the first pile, we dump horse manure, green waste from two cafeteria type kitchens, and a bit of the finer textured green waste from the landscapes. It eventually gets turned over into the second pile. By the time the second pile gets turned over into the third pile, it is almost ready for use. The third pile really does not last long. Neighbors take it as fast as we can.
We turn the piles when it is convenient for us and the tractor. There is no schedule. We incorporate the material as it becomes available. There is no recipe. Somehow, we get remarkably good compost from the process.
Besides the usual weeds that grow around the compost piles, there are all sort of vegetable plants that grow in the compost, from vegetable scraps and seed that were in the green waste from the kitchens. There are onions, potatoes, carrot tops and celery bottoms. For a while, there was even a pineapple top. Melons, cucumbers, peppers and squash sometimes grow from seed. Tomatoes are the most common vegetable plants out there.
All this random mix of vegetable plants started growing like weeds after all the rain last winter, but then slowed down after the rain stopped. That is why the tomatoes have not been ripening for long. Of course, we get no tomatoes. The raccoons an whatever other wildlife wants them tends to get them first. I am not so sure that I want tomatoes that seem to grow directly from horse manure anyway.
They sure look impressive though. It would be nice if tomato plants that were intentionally planted into vegetable gardens looked this good. There are actually a few just like this one scattered about where the compost gets turned. They sprawl over the ground, but are able to stand up enough to hold their developing fruit above the compost.
Silver
These are two pictures that did not make the grade for my ‘Six on Saturday‘ post this morning. That post featured bronze and gold foliage. Actually, of the six, only two were bronze, and only one was truly gold. One that I passed off as bronze was more purplish. Two that I thought were gold were just variegated with yellowish green and white.
I am none too keen on bronze or gold foliage anyway. The only exception that I can think of is the old fashioned bronzed ‘Schwedleri’ Norway maple. It was planted as a street trees on a few streets in the Santa Clara Valley in the 1950s.
Bronzed cultivars are less vigorous than their greener counterpart.
Gold cultivars are even less vigorous, and susceptible to scorch.
The best quality about bronze and gold is that they make silver look so good.
Olympic medal designations really should be reconsidered.
I only featured bronze and gold foliage earlier because I liked the contrasts between two different cultivars of each of the three species that were featured. Ironically, none of the three pairs compared bronze to gold directly. One compared purple to gold. The other two compared bronze to variegation that was barely yellow. Oh well.
There are neither bronze nor gold cultivars to compare to the silver foliage of the two species shown here.
I do not know what species of agave this is. There are not many distinguishable features visible in the picture above. The color and texture of the foliar surface might be identifiable to an expert. The little snail does not seem to be at all concerned.
The Eucalyptus cinerea in the picture below was pruned aggressively last autumn, both to contain the disfigured canopy, and also to stimulate more vigorous new juvenile growth. It is now strikingly silver.
Six on Saturday: No Silver
We have bronze, and we have gold, but we have no silver, at least not in these six pictures. I suppose I could have posted a picture of Eucalyptus cinerea or Echeveria glauca. I thought it would be more interesting to contrast two different cultivars of each of these three species. Only two are truly bronze. Only one is truly gold. They contrast nicely anyway.
1. Bronze smoke tree – Cotinus goggygria – Modern cultivars with richer color like this are now considered to be ‘purple’. When I studied it in the 1980s, the old fashioned bronze cultivars were still available.
2. Gold smoke tree – These might not have been available back in the 1980s. I do not remember every seeing one. I am not often impressed with their vigor; but I have seen them doing quite well in some situations.
3. Bronze canna – Canna spp. – I believe this is the cultivar ‘Wyoming’, with bronze foliage and rich orange bloom. The bronze color does not show up well here. Other cultivars are much darker purplish bronze.
4. Gold canna – Just as the bronze cannna is more bronze than it looks here, this one is more golden, particularly when the foliage is new. Obviously, it is variegated as well. The foliage is as interesting as the bloom.
5. Bronze New Zealand flax – Phormium tenax – It might be known by a cultivar name rather than the species name of ‘tenax‘ followed by a cultivar name. Weird modern hybridization complicates nomenclature.
6. Gold New Zealand flax – I really though that this one was ‘Yellow Wave’, but it does not look like that here. The variegation is more white than yellow. Could this variegation instead be classified as silvery?

Horridculture – Parking Lot Islands
What a waste of space! What a waste of water! What a waste of time for the mow-blow-and-go ‘gardener’ who charges money to mow and edge it, but are too inept to suggest planting something that might actually be pretty, or shade the parking lot. There are a few of these between parking spaces marked for ‘compact’ cars, because it is cool to discriminate against full size cars that can not pull far enough forward to get out of the way.
Even between a Buick and a Chrysler, it is nothing to look at. It looks like something went seriously wrong with a grave site that was supposed to get a slab ‘over’ it (not ‘around’ it). It could be a Chia Pet litter box. There are much better spots to picnic at the park down the road. Whatever it is, it is not much better than the swales that are required in modern parking lots. It has potential to be a tripping hazard, but is not quite as dangerous.
I would make one of only two suggestions.
1 Pave over it. If there is not some building code that limits the area that can be paved, this might be thee most practical long term solution.
2. Landscape it responsibly. Yes; ‘responsibly’. Turf grass is just lame. Those trendy carpet roses that mow-blow-and-go ‘gardeners’ typically plant snag the clothing of those coming and going from the cars they park there. Since parking lots get warm, I would recommend shade trees with complaisant roots that are compatible with pavement. Such shade trees also should get tall enough to not obscure the signs on the buildings.
Parking lot islands contain some of the most deplorable landscapes. Trees commonly get hacked down below signs rather than pruned up and over them. Even if they get properly pruned with up-dos, their canopies must be carve around security lighting. Most problems result from negligent maintenance. Some problems result from design glitches. Realistically though, parking lot islands are very difficult to landscape well.
Epiphyllum Surprise
Epiphyllum oxypetalum was my very first epiphyllum. A friend’s mother gave me three long cuttings, which were cut in half to make six cuttings. They grew like weeds, and I was quite pleased with them. At the time, they were the only epiphyllum that I wanted. The wide nocturnal flowers are strikingly pure white and nicely fragrant, and stay open late into the morning if the weather is right. Since white is my favorite color, I craved no more.
Then I got bits of another epiphyllum from one of my clients. I do not know if it really is a species of epiphyllum, but it grows just like one, with the exception of the bloom. Rather than only a few huge nocturnal flowers, it blooms with many smaller pink flowers that remain open all day. It lacks fragrance. It is not as impressive as Epiphyllum oxypetalum, but it is colorful for a longer time. Besides, now that I got it, I must continue to grow it.
Shortly afterward, I acquired a bit of another epiphyllum from another client. I expected it to bloom with a bright red flower, but it did nothing. In fact, it sat around for a few years without doing anything. Finally, it bloomed for the first time this year. That is the surprise.
This red epiphyllum that bloomed last year is not mine. It belongs to a colleague who hangs it in public garden at work while it is blooming. This is what I expected mine to look like. I sort of believe that it happens to be one of the more popular cultivars of epiphyllum.
What I got instead was these intriguing pink blooms! I don’t know what to think. The clear whit Epiphyllum oxypetalum is still my favorite, and I really like the rich red, but these pink flowers are totally rad too!
Trona
Trona is not as obscure as it seems. I would have needed to zoom in a bit more for it to appear on ‘Google Maps’, but it is there, just to the northwest of what seems to be a big crater of some sort in the middle, right where the map is labeled ‘Searles Valley’. You might have seen Trona before, from more flattering, or at least more realistic perspectives, in movies such as ‘Star Trek V’, ‘Planet of the Apes’ (2001), ‘Land of the Lost’ and ‘Holes’.
Earlier this morning, I posted an old brief article from March 21, 2018, Na2CO3•NaHCO3•2H2O. It was about some of what I find to be appealing, or at least compelling about Trona. Please excuse the euphemisms, such as ‘flattering’ for ‘realistic’, and ‘appealing’ for ‘compelling’. I happen to be rather fond of Trona, even though I have never been there before. I find that I appreciate it more as I learn more about the Community there.
Suddenly, Trona is in the news. A moderate earthquake occurred just west of town two days ago on the Fourth of July, and a stronger, although still ‘moderate’ earthquake occurred just yesterday morning. There were a few significant foreshocks, and the countless aftershocks, some of which are quite significant, will continue for a long time. Most of the damage was in Ridgcrest to the west, but only because there is more to damage there.
Earthquakes are nothing new here. We all know that they are more common here than in most other places. At one time or another, many of us here have experienced a moderate earthquake such as these. Of course, that does not make earthquakes any easier when they happen. Cleaning up the mess, repairing damage and recovering from an earthquake is a long process.
Six on Saturday: Under And Over
These are some of the bridges in the neighborhood where I work. There are several others that I did not get pictures of, as well as several more closer to town. Bean Creek happens to flow into Zayante Creek here, and Zayante Creek flows into the San Lorenzo River just a short distance away. Bean Creek flows through the farm a few miles upstream. Zayante Creek flows right past my home.
If you happen to know who Miley Cyrus is, she was photographed in the waterfall where Ferndell Creek flows into Bean Creek, which is literally just a few feet upstream from where Bean Creek flows into Zayante Creek. I do not know who she is, but I can understand why she came here to have her photograph taken.
1. Under the Conference Drive Bridge over Zayante Creek, East Zayante Road, Roaring Camp Road, Roaring Camp Railroad, and an access road to a (Rhody’s) baseball field, one would not guess that this bridge covers so much territory. The two roads below are on opposite sides of Zayante Creek. I posted pictures of this bridge before, but during winter while the box elders were bare. One box elder off to the left fell not too long ago.
2. Over Zayante Creek, just a short distance upstream and around a bend to the east, this small pedestrian bridge is closed until it can be repaired or replaced. Rhody does not seem to mind. Except for the light green box elders off in the distance, the trees to the left are some rather nice specimens of white alder. The foliage to the right is that of California buckeye, which is a weirdly ‘twice deciduous’ species that can defoliate during summer.
3. Under Roaring Camp Railroad Bridge over Zayante creek, just another short distance upstream from the pedestrian bridge (#2), we can see some more white alders, as well as some coast live oaks in the background. The lighter foliage to the left is likely box elders. This railroad passes under the significantly higher Conference Drive Bridge (#1) just a short distance in the opposite direction. They are almost perpendicular to each other.
4. Over a nicely landscaped section of Ferndell Creek, this small pedestrian bridge is probably the best place to see most of the rhododendrons when they bloom. Most are off the left, but that unrecognizable shrub to the right is one of the biggest. It is about ten feet above the bridge, and about twelve feet below! The big camellia that was killed by gophers earlier was just to the left at the far end of this bridge, just in front of the redwoods.
5. Under another pedestrian bridge just a very short distance downstream from the bridge pictured above (#4), recently planted Boston ivy is beginning to climb the pair of pillars in the background. Now that we know it does well here, we will eventually add more to climb the closer pair of pillars, after the English ivy gets removed. The site from which I removed sedge earlier is just upstream to the left, between the two pedestrian bridges.
6. Over Conference Drive, and a short distance up the road form the Conference Drive Bridge (#1), this small pedestrian bridge was built at a time when Conference Drive carried much more traffic. The road was closed to through traffic and bypassed in 1968. I like how the bridge leaps up into the redwoods and back down again on the far end. I need to prune these redwoods for clearance, but try to leave them cozily close to the bridge.

Horridculture – Tree Removal Permits
There are mixed emotions about tree removal permits that so many municipalities need to issue in order for a ‘heritage’ tree to be cut down legally. Most of us want to believe that in America, we have certain rights to do what we want to on the properties that we own. Obviously, that makes the most sense. However, if it were that simple, many more prominent trees that are collective assets to the larger communities would be removed.
As an arborist who writes the reports needed to procure these permits, I see it both ways. There are many trees that are worth preserving for the Community, and there are probably many more that must be removed for the safety of those who live around them.
I sometimes hear of common homeowners who get fined for removing a tree without a permit, just because they were not aware that it was protected by an ordnance. Most have lived in their homes longer than such ordinances existed. Most planted the tree that they were fined for removing.
Conversely, I also hear about developers who just remove whatever trees get in the way of their developments, and then just pay the necessary fines. It is nothing to them because they make so much money from the development.
The picture above is a site that one of my former employers worked on just before I left my job because it was too morally challenging. You can see that there are no significant trees. The tree crew removed all of them.
I was not aware of it of course. The Home Owners Association did not want to pay for my inspections and reports, or for the permits to remove all the big sycamores in the front gardens there. Nor did they want to replace the removed trees with something more proportionate, as the local municipality would have required. They were not worried about getting caught, since everyone there wanted the trees gone.
Now realistically, I would have had no problem writing reports recommending the removal of all the trees, because they were ridiculously disproportionate to their particular application. You can see how tiny the front gardens are. It was just easier and less expensive to cut the trees down illegally, and then not be required to replace them with trees that would have later died ‘accidentally’ anyway. (The tree crew excelled at that too.)
In the end, it is disgraceful that the trees that were required as a contingency when the site was developed years earlier are now completely gone, and will not be replaced, . . . and that no one seems to care.
Boom! Zap! Wow! Bam! Zing!
Batman and Robin were here!
. . . well, not quite. It is decoration for summer camp. We never know what we will find in the landscapes that we maintain here. Those who work at camp arrive before guests, so that they can get ready, and of course, to decorate. Guests only started to arrive two weeks ago. It makes our work more interesting, as we try to work around the traffic and events, but it is SO gratifying to see so many guests enjoy the facilities that we maintain!
Those who work at camp enjoy being here too. It is obvious in all the work they put into preparation. It gets pretty wild and colorful, as I was reminded when I found what had been done in a grove of coast live oak just outside of one of the main auditoriums. Last year, I pruned and groomed the trees to expose their naturally sculptural trunks. I thought they were rather exemplary; but apparently, there was some room for improvement.
There is more to the wardrobe of a well rounded tree than mere ‘trunks’. One might select stylish attire such as this. Really though, I am not certain if this tree is feeling ‘Absolutely Fabulous’ or totally embarrassed.
This one went for an old fashioned veil.
English ivy on the ground below the grove is wearing too much makeup.
It is not really makeup of course. It is paint from this mysteriously hovering door . . . as if that somehow makes more sense. It was locked.
This one is more my style, and it has a window. There is no need to open it to see what is outside . . . or inside.
If neither of those are good enough, there are plenty of others to choose from.
