Horridculture – Keep Out!

Gilroy City Council does not endorse this landscape.

Corner lots can be challenging. Even if paths do not get worn diagonally through front lawns, vegetation between curbs and sidewalks is likely to get trampled. The pavement in the foreground of this picture connects the sidewalk to crosswalks for the two associated streets. (I realize that this is not a very good picture, and the blotched out poster for a candidate for Gilroy City Council could not be erased completely, but I took it from a car while stopped at a stop sign.) Vegetation for this particular application must be durable, and perhaps deterrent to trampling. This particular vegetation certainly conforms in that regard. However, there is no polite way of saying how extremely dysfunctional this landscape is. Firstly, from the get go, it is very dangerous to anyone who might simply trip and fall as people sometimes do. Secondly, this landscape will become more dangerous as it matures. Although most of the already crowded agaves seem to be a somewhat compact cultivar that should not reach very far over the sidewalk, the specimen at the center of the bottom of the picture seems to be a variegated common century plant, which has potential to reach halfway across the sidewalk. Thirdly, the entire hot mess will be hideous as it soon needs to be pruned for clearance. The sago palm will soon reach the sidewalk like the common century plant. Pruning will destroy their foliar form. The Mexican fan palm should eventually grow upward and out of the way, but will eventually prevent the streetlamp from illuminating a portion of the sidewalk close to the corner, where illumination is relatively important. Fourthly, this collective herd of wickedly hateful vegetation will soon be too congested to remove litter or weeds from; and curbside landscapes such as this innately collect litter.

‘Karpooravalli’ Banana

‘Karpooravalli’ is a relatively undemanding cultivar.

‘Cavendish’ and its variants have always been the most familiar types of banana locally. They are the most popular that are available from produce markets. From nurseries, they remain the most commonly available cultivars. A few other options are only beginning to become available. A few of these could be more reliably productive within local climates.

‘Karpooravalli’ has been available here for quite a while, but remains uncommon. Those who are familiar with it often describe it as wanting ‘only sunshine and water.’ It tolerates soil of inferior quality better than other cultivars, and craves less fertilizer. Within rich soil, it may crave none. It should likely stay away from fences that its pups could sneak under.

‘Karpooravalli’ is supposedly the sweetest of the Indian bananas. Although its fruit is a bit shorter than more familiar bananas, it is often a bit plumper. Ripe fruit is yellow with pale green blush, and delightfully aromatic. Foliage is more resilient to wind than that of most other cultivars. It can stand more than fifteen feet tall on its very vigorous pseudostems.

Banana Trees Actually Produce Bananas

Banana trees provide boldly lush foliage.

Banana trees, much like palms, arboriform yuccas and cordylines, are herbaceous trees. They develop no secondary xylem, or wood. What seems to be trunks are pseudostems, which are just leaves in very tight bundles. These pseudostems grow from subterranean corms, which can grow rather big. Each pseudostem is monocarpic, so dies after bloom.

Although they are very easy to grow, banana trees are not very popular. They can be too easy to grow, and become overwhelming. In some climates, frost can ruin their foliage for part of the year. In some exposures, their foliage can get shabby from wind. Some expect generous and frequent applications of fertilizer. All want generous and frequent irrigation.

These characteristics are contrary to growing banana trees merely for appealing foliage. Realistically, that is what most are for. Those of the Ensente genus are fortunately easier to maintain, but fruitless. Their lushly huge leaves are spectacular, relatively durable and generate much less debris. However, after a few years, they die without generating pups.

Banana trees of the Musa genus generate fruit, although some are primarily ornamental. A few produce delightfully colorful fruit that is too small, seedy or starchy to be palatable. Musa are more pervasive although less popular than Ensente. While Ensente come and go, Musa are reliably perennial. Several produce enough pups to potentially be invasive.

Musa, unlike Ensente, therefore develops colonies of a few to many pseudostem trunks. A few new trunks can replace each old trunk faster than they can deteriorate after bloom. Removal of deteriorating old trunks promotes growth and fruiting of new trunks. So does culling of congested new trunks. They propagate very easily by division with intact roots.

Because banana trees are tropical, they are unfamiliar with the seasons here. They grow fast with warmth but very slowly without it. They bloom randomly though. Flowers that try to bloom during autumn may stagnate long enough to rot through winter. Late fruit can do the same. Fruit that begins to develop early is much more likely to finish prior to autumn. Some cultivars develop faster.

Redwoods & Gravity

Physics are dangerous!

Sequoia sempervirens, coastal redwood is the Official State Tree of California, and the tallest species of tree in the World. One large specimen can contain more lumber than many acres of Douglas fir (really). While some trees ensnare kites, redwoods collect satellites. Redwood lumber can be delivered anywhere in western North America simply by aiming a tree in the direction of delivery while cutting it down. Redwood shadows reach Japan at dawn and New England at dusk. The moon is covered with craters because it could not dodge the growing redwoods while orbiting over California. You can see for yourself how tall redwoods are just by looking in this direction from wherever you are in the World. Unfortunately though, not all of the debris that falls from the huge canopies of redwoods burns up in the atmosphere on its way down. Such huge canopies generate a lot of debris. Almost all of it is finely textured foliar debris. Some is twiggy detritus. The worst of it are significant branches. The descent of most of such branches is slowed by lower branches and foliage that they encounter on their way down. However, the lowest branches of some canopies are very high up, and falling branches resume acceleration after falling past them. Also, some falling branches fall outside of their canopies. Even branches that weigh only a few pounds can be extremely dangerous. Many falling branches weigh many pounds, and some are as big as trees. The fallen branch in the picture above is only several feet long and about three inches wide, (and happened to fall through the only three inch wide plank in a pedestrian bridge. The replacement plank needed to be custom cut.) I am annoyed by this relatively minor damage, but also relieved that it was not worse.

Nix

Buick / Lincoln

Carson, Rhody’s Roady, is a 1994 Roadmaster. Although Chevrolet Caprice, Oldsmobile Ninety-Eight and Cadillac Fleetwood are the same sorts of contemporary sedans, Buick Roadmaster is somehow designated as the last great American Sedan. All are very rare, likely because they were already so old fashioned when they were new. Finding Carson was no easy task. In the process, and to be a responsible consumer, I investigated other options, including Mercury Grand Marquis from about the same time. Ultimately, I really wanted a Buick, which is a bit more refined than a Chevrolet, but not quite as vain as a Cadillac. Although all options were very tempting, I have been completely pleased with Carson. A few weeks ago though, this 1992 Lincoln Town Car was acquired by the fleet at work. Because most of who work here are young people who lack appreciation for real sedans, particularly such totally awesome luxury sedans, this Town Car will be sold. Because such sedans are even more old fashioned than they were when they were new decades ago, it will not be sold for much. Goodness! It is extremely tempting. Town Car is the luxurious Lincoln version of the Mercury Grand Marquis. This particular Town Car is of the Cartier Edition, which would be a bit too froufrou for me if I could see what identifies it as such. I believe that his name is Nix, but I just refer to him as the Town Car to avoid getting too familiar or attached. His trunk is nearly as spacious as Carson’s, so can bring more plant material back from Southern California or the Pacific Northwest than a modern compact pickup, which was one of the justifications for investing in a sedan that I have no practical use for rather than a modern pickup.

Six on Saturday: Fake Autumn

Daylight does not last quite as long as it had earlier in summer. Shadows stay noticeably longer. Summer actually ended about two weeks ago. For now it is early Indian summer.

1. “Bunny Xing” is as irrelevant to autumn as it is to Charing Cross Road in Los Angeles. I just found it to be amusingly odd that a neighbor seems to be protective of wildlife that can be so detrimental to some gardens here. Bunnies fortunately do not bother us much.

2. Juglans nigra, Eastern black walnut or Juglans nigra X hindsii, royal walnut, yellows early, more likely because it is tired of summer heat than because it anticipates autumn. Both walnut tree types naturalized from understock that sustained old walnut orchards.

3. Quercus lobata, valley oak typically but not always begins to brown after walnut trees yellow. This yellowish color is likely a result of the weather cooling a bit before warming again. This species is native nearby, but may have naturalized here after getting planted.

4. Acer rubrum, red maple is likely only coloring because it is distressed by confinement of its roots within its big clay pot. Recent and suddenly warmer weather after seasonably cooler weather may have accelerated the process. I really want these trees in the ground!

5. Helianthus annuus, sunflower mysteriously appeared precisely where we should have but neglected to grow sunflowers this year. This is the only one, but it is enough to show us what we are missing because of our lack of diligence. It is only a bit early for autumn.

6. Rhody is ready for autumn. More specifically, he is ready for cooler weather. Although it was scarcely more than ninety degrees yesterday, and only for a few hours after noon, it seemed to be unseasonably warm, after earlier weather was already beginning to cool.

Dwarf Alberta Spruce

Dwarf Alberta spruce is more like a strictly conical shrub than a small tree.

Unlike other related white spruce, which get more than fifty feet tall, dwarf Alberta spruce, Picea glauca albertiana ‘Conica’, stays smaller than its Latin name, rarely getting more than seven feet tall. It is so dense and conical that it should never need to be pruned. Shearing only damages its short light green to grayish green needles. Dwarf Alberta spruce is compact enough to live in large tubs or urns, as long as its sensitive roots are well insulated. (Concrete or wooden planters are well insulated, so do not transfer too much heat to the roots within. Ivy or ground cover cascading over and shading planters also helps.) Foliage should be sheltered from harsh exposure, since it can be desiccated by warm breezes or reflected glare, like from large windows or light colored south facing walls.

The Stakes Are High.

Binding nursery stakes should be replaced with less restrictive staking and straps.

            After all the unnatural things that plants must endure to get into gardens and landscapes, it is amazing that they are as happy as they are to perform. Most come from very different climates, only to be grown in artificial nursery conditions while confined to containers, then get shipped to other different climates where they get planted in foreign soil, and are expected to adapt. Nonetheless, they still provide flowers, fruit, vegetables, shade and all that we expect from them!

             Trees must suffer even more. Their lower growth that should enhance trunk growth gets pruned away prematurely. Trunk growth is further inhibited by staking, which is ironically necessary for straight and vertical trunks. Fortunately, most trees recover from these procedures.

            Weaning trees off their original stakes can take a bit of work though. Because of their lanky trunks and disproportionately bulky canopies, most new trees need help to stand up against the wind. Except for palms and a few stout trees that are allowed to keep their lower growth, such as redwoods and some pines, almost all trees need to be staked when planted. However, their trunks should not be bound so tightly that they rely on their stakes for support.

            Stakes that are proportionate to new trees should be installed as the trees get planted. They should ideally be a few inches away from the trees and stand as high as necessary to provide adequate support. A small tree (such as #5 or 5 gallon) may need only a single stake. A larger tree (such as #15 or 15 gallon or larger) typically needs two stakes on opposite sides. The original ‘nursery stakes’ that are bound to the trunks should then be removed as trees then get tied to their new stakes. Trees will need to be supported during this process.

            Trees like red maple or flowering pear that have stronger trunks that do not bend much may only need to be tied at the top, just above their lowest limbs. Most trees have more flexible trunks though, so also need to be tied lower down, generally about halfway between the ground and the top tie. Very flexible trees, like many eucalypti, may need to be tied in even more places. Since there are rarely branches on the trunks to keep the lower ties from sliding downward, the ties may need to be nailed to the stakes.

            Ties should wrap around the trunks and cross over before wrapping around the stakes; in a ‘figure 8’ pattern. This limits abrasion from the stake against the trunks. Ties made from recycled tires with bailing wire at the ends are ideal and easiest. For larger lodgepole stakes, recycled tire ties without wire can be nailed directly to the stakes. Ties should only support trees as they blow away from their stakes or bow from their own weight, but should not bind them firmly to the stakes. This way, trees need to become able to support their own weight.

            As trees mature and no longer need support, stakes and ties should be removed. Stakes and ties that get left too long can actually interfere with trunk development, and cause significant damage and abrasion as trunks expand.

Horridculture – African

Delegates from Arabia, Africa, Germany Pakistan and (almost) Turkey

‘The Rescuers’ is an animated movie for children from 1977 that features the Rescue Aid Society, which is an international organization of mice. (I am trying to be very brief with this description. Besides, I do not know much about it.) Delegates of the Rescue Aid Society represent various countries, such as Arabia, Germany, Pakistan, Turkey and Africa. Yes, ‘Africa’. Although one can assume that ‘Arabia’ refers to Saudi Arabia, it could refer to the entire region, which includes several countries. Similarly, although one can assume that ‘Germany’ refers to West Germany, it could refer to both West Germany and East Germany, which were still separate countries in 1977. ‘Africa’, though, is not so easily dismissed. It is an entire continent, which includes more countries than any other continent. Horticulturally, Africa does not get much more regard. African sumac, African daisy, African iris, African violet and African tulip tree are all from Africa, but their names reveal no more than that about their origin. Italian cypress, English holly, French lavender, Norway spruce and Grecian bay all have names that are more descriptive about their European origins. Similarly, the names of Japanese boxwood, Chinese elm, Korean fir, Burmese honeysuckle and Indian laurel describe their Asian origins. The names of California fan palm, Oregon grape, Virginia creeper, Texas bluebonnet and Arizona cypress are even more descriptive, by designating individual States within the United States of America, which is within the continent of North America. Here in California, some common names are even more regionally descriptive, such as Monterey pine, Santa Cruz cypress, Santa Barbara daisy, San Francisco campion and Montara manzanita. Although most of these examples are unknown or rare beyond their native ranges, a few are quite common elsewhere. Yet, somehow, most of what was exported from Africa is merely ‘African’.

California Fan Palm

California fan palm is almost native.

California fan palm, Washingtonia filifera, is the only palm that is native to California. It is naturally exclusive to very distinct ecosystems, though. It inhabits isolated riparian oases of the Colorado Desert. Some also inhabit the Mojave Desert and the Sonoran Desert. It prefers arid warmth. Unfortunately, it may not perform as well within milder climates here.

Otherwise, it is a stately palm that is more adaptable than most are to formal landscapes. It resembles Mexican fan palm, but is shorter and stouter, with a fluffier canopy. It tends to stand straighter, with neatly bare gray trunks. Groomed trees rarely retain petiole stubble. Alternatively, they are handsome, although combustible, with full beards of dried leaves.

California fan palm grows about fifty feet tall, and taller in the wild. Its canopy may be ten to fifteen feet wide. If flattened, its fronds, or complete leaves, might be more than ten feet long. Stiff petioles, with rigid and sharp teeth, are a bit more than half of their total length. The species name filifera describes filaments that hang from the clefts of fronds, and new bud growth.
