GREEN

P71112

GREEN – Greening Residential Environments Empowering Neighborhoods – allocates resources, procured from both municipal funding and private donations, to the installation, maintenance and protection of trees in public spaces within the collective urban forest of Los Angeles, and to the enforcement of environmental justice.

How is that for a mission statement?

It is no coincidence that GREEN is also Brent’s last name. He is quite vain. Really though, it works.

Brent has been planting street trees since we were in school in the 1980s, and did his first big project of thirty trees in the median of San Vicente Boulevard on his thirtieth birthday in 1998. This January, twenty years later, he will be planting fifty more trees.

Here and there, I will be writing more articles about these projects. They are too involved to write just one article about. For now, I would like to mention the Facebook page…

Six on Saturday: LOG!

What rolls down stairs
alone or in pairs,
and over your neighbor’s dog?
What’s great for a snack,
And fits on your back?
It’s log, log, log

It’s log, it’s log,
It’s big, it’s heavy, it’s wood.
It’s log, it’s log, it’s better than bad, it’s good.”

Everyone wants a log
You’re gonna love it, log
Come on and get your log
Everyone needs a log
log log log

Hopefully, no one remembers this. Anyway, vegetation management has become something of a priority recently, and has been generating a bit of firewood.

1. LOG! From Blammo! Actually, this one is from a bigleaf maple, Acer macrophyllum. It is an exemplary specimen, artfully displayed against a backdrop of sawdust scattered over asphalt.

2. Pseudotsuga menziesii, Douglas fir is cruddy firewood that can ruin carpet inside a car if moved while green and sappy, but most was gone by the time I got this picture. It is all gone now.

3. (Notho)lithocarpus densiflorus, tanoak is much better firewood. It is also my least favorite of native trees here. It smells like bad salami while in bloom, and produces irritating tomentum.

4. Ligustrum japonicum, waxleaf privet is not native. It was likely a remnant of a prehistoric landscape, rather than self sown. The few logs are nothing to brag about, but will burn like olive.

5. Umbellularia californica, California bay was claimed before it was stacked, so was outfitted with a sign that read, “This bay is not free. (This ain’t FREEBAY!) LOL – LOL”. It smell badly!

6. Acer macrophyllum, bigleaf maple, according to the sign, is for Aunt Jemima. It is one of my favorite native species, but is notably uncommon, so I am none too keen on cutting any down.

Chrysanthemum

Chrysanthemums are just right for autumn.

Mild autumns and arid summers keep chrysanthemums on a different schedule here than in most other regions. They can get planted in spring to grow through summer and bloom through autumn; but because they can take a bit of work, they are more often planted while blooming in autumn. Although commonly grown as autumn annuals, they are perennials that can regenerate next spring, grow through summer, and bloom even better the following autumn.

Centuries of development in Japan have produced more varieties of chrysanthemums than can be documented. There are really some weird types grown for cut flowers or by hobbyists. Garden varieties are mostly limited to simpler flowers that do not need much thinning or staking. Color ranges through all sorts of hues and shades of yellow, orange, red, pink and bronze, as well as a few purplish colors, cream and white. Many have yellow centers. The aromatic foliage is alluring to some, but objectionable to others.

Snails, Weeds And Falling Leaves

Gardening does not slow for autumn.

The coloring of foliage is a bit slow this autumn. The cooling nights after such warm weather is bringing some of the deciduous foliage down while it is barely yellowing. Honeylocust and black oak have already gotten notably sparse without much notable color. Hopefully, the more colorful sweetgum, flowering pear, pistache and gingko trees will retain their foliage later into cooler weather, so that they can put on a worthy show before filling compost piles.

It is probably slightly too early to clean gutters and downspouts. Unless the rainy season somehow starts first, this should probably wait until most of the foliage that is expected to fall has already fallen. Lawns, certain ground covers, decks and pavement should be raked as needed though. Decks and pavement can get stained from the tannins that leach from decomposing foliage. Lawn and ground cover do not like the shade under the debris.

However, slugs and snails really dig the mess. Fallen foliage keeps the ground cool, damp and shaded. Raking leaves does not eliminate slugs and snails, but inhibits their proliferation. There are always plenty of other hiding places. As the weather eventually gets cooler and damp, snails that stay out in the early morning should be collected and disposed of. Of course this technique is not convenient for everyone, since most snails hide before the sun comes up. Small slugs hide earlier in the morning and are even more unpleasant to handle.

Once found, neither slugs nor snails are too elusive . . . or fast. Yet, plucking and collecting them is not a fun job. Once collected, no one knows what to do with them. They can be put into plastic bags and disposed of; and will eventually succumb. Some people prefer to simply toss them onto a dry and sunny driveway or roof where they succumb more quickly and get taken by birds. Snails may need to be squashed to limit mobility.

Even though it is too late to prevent most types of weeds from dispersing their seed, a few types continue to disperse seed as they deteriorate through autumn and winter. Weeds in areas that get watered last longer and disperse their seed later than those without watering. Perennial weeds that are still green in dry areas areas will be easier to pull after the first rain.

Seriously?!

Articles such as this one from three years ago are why I now typically write to comply with the ‘Horridculture’ theme on Wednesdays.

P71104Gardening is not for everyone. If you are reading this, you probably enjoy gardening. There are many more people who simply are not interested in it. Some tend to their own gardens in a basic manner just to keep their homes looking good. Most hire gardeners to maintain their landscapes for them.

I use the term ‘maintain’ very lightly. What they really do is keep the lawn from getting too deep, and other plants from getting too overgrown. Very few really care how they accomplish these basic requirements.

I could go into the detail about how they brag about saving water while wasting enough to drown trees, or how they shear everything within reach into nondescript . . . whatever they get shorn into, or how most problems that arborists encounter in their work are caused by gardeners. Instead, I am just gong to talk briefly about two examples of…

Ginkgo

Ginkgo is turning clear bright yellow.

Where autumn chill is minimal, the best and brightest yellow autumn color is that of the ginkgo, Ginkgo biloba. Some know it at the maidenhair tree. Except for older trees that produce messy and stinky fruit, it is a notably clean tree. Perhaps it is too clean. It drops nothing all year, but can defoliate too soon once it develops it striking autumn color. Minimal chill actually prolongs the process.

Ginkgo is dioecious, with separate genders. Modern cultivars for landscapes are male, so produce no obnoxious fruit. Female cultivars that produce nuts and fruits are not commonly available in nurseries locally. (As objectionable as their aroma is, the nuts and fruits are edible.) Some people may be allergic to the pollen of mature male trees. Many mature trees predate modern cultivars.

Trees are somewhat slender and perhaps sparse while young. They develop a broader canopy as they age. Trees can get more than fifty feet tall, with sculpturally irregular branch structure. Foliar venation radiates outward from the petioles. Leaves, which are about two or three inches long, therefore have the shape of fishtails. Leaves on current season stems are cloven into paired lobes.

Autumn Color From Deciduous Foliage

Deciduous foliage can get delightfully colorful.

Autumn does not get cool enough locally to prevent everything from blooming. A few plants can bloom sporadically all year except only during the coolest part of winter. A few plants naturally bloom in autumn. Cool season annuals begin blooming before warm season annuals finish. Flowers can potentially provide plenty of autumn color if necessary. A mild climate can be a major advantage.

It can also be a disadvantage. Minimal chill causes deciduous foliage to start to get messy before it starts to get colorful. Some deciduous plants shed completely before getting chilled enough to develop appealing autumn color. A few others do not even get cool enough to defoliate completely. They instead retain their shabby old foliage through winter until new foliage replaces it in spring.

Nonetheless, several adaptable deciduous plants get sufficient chill to develop impressive autumn color here.

Sweetgum, Chinese pistache, flowering pear and ginkgo are likely the four best deciduous trees for autumn color locally. Sweetgum and Chinese pistache produce the most impressive ranges of vibrant colors. Flowering pear is comparable, but with less yellow, and more rich deep burgundy red. Ginkgo lacks such range of color, but develops the brightest and clearest yellow autumn color.

Boston ivy, crape myrtle and persimmon get about as colorful as sweetgum, even if incidentally to their primary duties. Crape myrtle is popular for its abundant and richly colorful bloom in summer. Persimmon is a fruit tree. Boston ivy obscures graffiti and helps muffle sound on freeway soundwalls. Cottonwood and black walnut turn bright yellow, but in the wild rather than in refined gardens.

Even for the locally mild climate, there are plenty of deciduous plants that provide foliar autumn color. Trees are the most familiar. Vines and shrubbery are also popular. Because this mild climate is marginal for some of them, color is likely to be variable from year to year. Unfortunately, some that perform satisfactorily for inland locations may perform less satisfactorily in coastal conditions.

Colors

tonytomeo's avatarTony Tomeo

P71029+Remember the movie from 1988? I don’t either. I never saw it. Gang violence is not my idea of a good time. The title ‘Colors’ refers to the use of distinguishing colors by the gangs of Los Angeles. Gang members wear colors that correspond to their respective gang affiliation.

As autumn progresses, some of us get to gloat about our colors. New England gets the most and best colors, with a full range of reds, oranges and yellows, as well as browns and burgundies. The Appalachian Mountains to the south seem to go lighter on the reds and burgundies, concentrating more on oranges. The upper Midwest around Minnesota excels at the rich reds, with yellows confined to groves of cottonwoods. The lower Midwest does well with clear browns alternating with yellows, and even some oranges. The Rocky Mountains have a good range of color, with more gold than the Appalachians…

My Tiny Downtown Garden

tonytomeo's avatarTony Tomeo

P71105Main Street and Santa Cruz Avenue are the two main streets of downtown Los Gatos. They are the main shopping district, and the part of town that everyone sees. As much as things have changed, a bit of the familiar remains. Gilley’s Coffee Shoppe is still next door to the (rebuilt) Los Gatos Cinema. The brick La Canada Building miraculously survived the Earthquake. The simple deco Park Vista Building across the street is just as elegant now as it was a century ago. There are still concerts in the Town Plaza in summertime, shaded by the Town Christmas Tree that gets lit up in December.

Both Main Street and Santa Cruz Avenue are outfitted with big planter boxes that give the downtown a more relaxed and colorful ambiance. Each planter is elevated about a foot and a half, and contains one or two Indian hawthorn trees. A low wrought iron…

Six on Saturday: Vegetation Management Gone Bad

The last three of these six are rather embarrassing. Perhaps I should have omitted them. Some might find them to be amusing. Some of the buildings here are more than a century old. Even more originally lacked electricity. Much of the wiring is substandard by modern regulations. Some is downright shoddy, and susceptible to damage from . . . vegetation management.

1. Ash is STILL everywhere! Even without rain, it should have blown away in any breeze. Instead, it is a constant reminder of why we must be more diligent about vegetation management.

2. Strangely atypical foliar scorch damaged several rhododendron and a few other plants during evacuation. Sheltered foliage is as scorched as exposed foliage. There is no time for grooming.

3. Volunteers are helping with vegetation management at cabins that are inhabited by some who lost their homes. Even if it were not green, resulting ‘fire’wood is unlikely to be popular here.

4. Before I continue, I should point out the cruddy pipe clamp that is barely attached to weathered trim by only a short screw. It is right there in the middle. Its other short screw is missing.

5. This is what the pipe clamp was supporting. The large box leaning out from the wall is the fuse box. The smaller box is the electrical meter. The pipe to the lower right is electrical conduit.

6. Something so important and potentially hazardous should have been secured by more than two small screws. It should not have been so easily dislodged by a smack from the top two feet of a bay tree. This thing made major sparks when it hit the ground. It could have started another fire! Anyway, the tree was removed. We are actually careful about vegetation management.
