Horridculture – Unpruned Fruit Trees

The majority of fruit trees require intensive and specialized maintenance.

tonytomeo's avatarTony Tomeo

P90529They do not come with instructions for their maintenance. Deciduous fruit trees, particularly the stone fruit trees (such as cherry, plum, prune, apricot nectarine and peach) and pomme fruit trees (such as apple and pear), can be procured as easily as nasturtium seed or petunias. Whether bare-root in winter or canned (potted), they very often get planted into gardens where they are expected to produce their fruit as easily as daisies bloom.
Instructions for planting that come with bare root stock are useful for getting those particular trees started, but mention nothing about how even brand new trees need to be pruned after installation, and will need specialized pruning annually every winter thereafter. The same applies to rose, raspberry, blackberry (all varieties), grape, and to a lesser extent, fig, pomegranate, persimmon and several other fruit producing trees, vines and shrubs.
The problem with the stone fruit and pomme fruit trees…

Red Willow

Red willow is a riparian native.

Of the few native species that share the same designation of ‘red willow’, Salix lasiandra, is likely the most common locally. However, it has a few other common names, including shining willow and Pacific willow. For those acquainted with it, recognition is easier than nomenclature. It is not a problem though, since red willow is rarely an intentional choice.

Red willows, including less common species, grow wild in local riparian situations. They sometimes sneak into home gardens, particularly if irrigation is generous. Their rampant growth is susceptible to spontaneous limb failure. Pruning can compensate for structural deficiency of young trees. However, trunks typically succumb to decay within thirty years.

Mature trees are mostly less than thirty feet tall, typically with low branches, and possibly with a few elegant trunks. The gray or light brown bark is finely furrowed. The deciduous foliage has a slight sheen, and then turns brownish yellow prior to autumn defoliation. Its narrow leaves are about three inches long. Twigs are yellowish or green rather than red, as it implies.

Nature Is Not Naturally Accommodating

Many trees naturally exhibit irregular form.

Gardening is quite unnatural. It involves unnatural cultivation of mostly unnaturally exotic (nonnative) species of plants. Irrigation delivers more water than seasonal rain provides. Fertilizers contribute more nutrients than endemic soils provide. Pesticides, if necessary, inhibit proliferation of pathogens. Nature simply could not accommodate such demands.

Not only is gardening unnatural, but it also interferes with established ecosystems. Many aggressively invasive plants were formerly desirable exotic plants that naturalized. Many pathogens arrived with exotic plants. Several naturalized plants have potential to distract native pollinators from native plants that rely on their pollination. It is an ecological mess.

Nonetheless, it works. Gardening within the constraints of nature would be unproductive. Most residents of California inhabit chaparral or desert climates that originally sustained limited vegetation. Such limited vegetation sustained a very limited indigenous populace within relatively vast areas. Modern residential parcels would be completely inadequate.

That is the justification for gardening, whether for sustenance, or merely to beautify home environments. Unnatural breeding continues to improve performance of many useful and appealing plants. Unnatural horticultural techniques generate more desirable vegetation within confinement of urban gardens than would naturally inhabit a few acres in the wild.

Nature remains relevant though. All plants originated within nature somewhere. Besides their basic requirements, exotic plants prefer environmental conditions that are similar to those of their natural origin. Some tropical plants crave more warmth and humidity. Some plants prefer more winter chill. Most popular exotic plants rely on supplemental irrigation.

Physical characteristics of many plants necessitate special accommodations also. Roots of plants that naturally compete in dense jungles are likely to damage pavement. Without adequate pruning, native plants that naturally exploit burn cycles can become perilously combustible. Many vines naturally try to overwhelm nearby vegetation and infrastructure.

Campground II

I sometimes inspect weirdly fallen trees for clients, but did not expect to observe such a weird subject right here.

tonytomeo's avatarTony Tomeo

P90626This is a formerly unplanned sequel to the article ‘Campground‘ from last Sunday. That article described my concern for any of the homeless who might camp on the banks of an adjacent creek, below innately unstable and structurally deficient riparian trees. Just a few minutes after the article posted at midnight, the biggest and most deteriorated box elder tree in the area of concern coincidentally fell! No one was there at the time to be hurt.
The tree that fell was located just a few yards to the right of those in the picture of the previous article. It happened to be the only tree that was inside the fence. Therefore, as it fell inward, it did not damage the fence. The trailer that it landed on is for heavy tractors, so was undamaged. Only the top few timbers of a pile of lumber that it landed on…

Garter Snake

Ah, the weird surprises of gardening.

tonytomeo's avatarTony Tomeo

P90525KThis little critter surprised me at work last week. Even though I knew it to be harmless, my instinctual response was to get away from it fast. I have encountered enough rattlesnakes to know better than to take the time to identify a snake before getting some distance from it. Even after identifying a snake as a harmless garter snake, I still prefer to avoid it as it leaves. This one was in no hurry, so got picked up with a rake and set safely aside.
Between high school and college, I took a summer job for a (primarily) retail nursery in Miramar on the coast of San Mateo County. At this job, I sometime went with the maintenance crew to work in a few home gardens. At one such job, just overlooking the beach in Montara, I needed to mow an overgrown lawn. Rather than mow back and forth…

Six on Saturday: Rhody’s Rhodies 2022 – Prettier Than Pink? – (a sequel)

Some flowers excel with particular colors. Jacaranda is best in blue. White looks plain or boring. California poppy is best in natural orange. Pale white, pale purple, pink and any other modern color seems weird for them. Poinsettia should be red, or perhaps white or pink, but not ‘peach’, ‘plum’ (whatever color that is) or yellow! Although I had never met a rhododendron that I did not like, I do find that the best are either purple or red. Pinks are very appealing too, but not quite as ideal as the others. White rhododendrons can be rather bland. These six rhododendrons bloomed prior to last Saturday. Since I intend to limit the redundancy of pictures of rhododendrons this season, they will be the last.

1. White is my favorite color. White rhododendrons should therefore be my favorites. So, are they? I would prefer this one to be brighter white, without tan spots or pink stamens.

2. White, to me, seems mundane for rhododendrons anyway. This is brighter white than the other, and lacks pink stamens, but has yellow centers. Simple white would be better.

3. Lavender, or whatever this color is, seems a bit more appropriate for rhododendrons. It is slightly more pinkish than it seems in this picture. Can it really qualify as lavender?

4. Lavender is a tint of purple, like pastel purple. Therefore, this may qualify as lavender more than the previous picture. It is slightly more bluish, with a slightly ruffly structure.

5. ‘Anah Kruschke’ was likely the most popular cultivar grown on the farm, and for good reasons. The pinkish purple bloom is exquisite and reliable. Foliage with form are ideal.

6. Purple and red are, in my opinion, the best colors for rhododendrons. Not many other flowers can bloom with such rich purples and reds. Other flowers provide better whites.

Red Passion Flower Vine

Red passion flower seems quite exotic.

Compared to the common passion flower, the three inch wide red passion flower, Passiflora manicata, is more colorful with cherry red flowers, but does not so prominently display the weirdly distended floral parts that passion flowers are known for. Bloom is not as profuse either, particularly among vigorous vines.

However, red passion flower vine has the advantages of somewhat more resilient and greener foliage, and sturdier vines that can climb almost to thirty feet high. It grows so vigorously that it can be surprisingly overwhelming, even if pruned severely or cut to the ground at the end of each winter. It is not so rampant in light shade.

Copies (new vines) are easy to propagate by layering, which involves merely burying a section of vine while still attached to the parent vine until it develops enough roots to be separated. The buried section should be at least a few inches long. At least a few inches of the tip of the vine should extend beyond the buried section.

The fruit of red passion flower vine is considered to be toxic, but often gets eaten anyway. Fortunately, fruit rarely develops.

Vines Have Unique Personalities

English ivy clings with aerial roots.

Boston ivy and creeping fig are good aggressive vines for freeway overpasses and sound-walls. They are resilient to harsh exposures and pollution, and help to muffle the sound of traffic. Boston ivy provides remarkable foliar color in autumn before defoliating in winter. Creeping fig provides thick evergreen foliage that overwhelms any graffiti that it can reach.

However, their aggressive behavior that is such an advantage on freeways is precisely why they are not so practical for home gardens. Boston ivy gets around so efficiently because it grabs onto surfaces with ‘holdfast disks’ (modified tendrils) that damage paint, stucco, wood and just about anything that is not built like a freeway. Creeping fig is at least as destructive with clinging aerial roots, as well as constrictive stems that can crush smaller plants, fences and anything else that it might grab hold of.

Most vines are aggressive in nature. They exploit trees for support, and then compete with them for space. Some are complaisant enough to mingle relatively peacefully with the trees that support them. Less honorable vines have no problem overwhelming the canopies of their supportive trees. Creeping fig and other related figs are known as ‘strangler figs’ because their constrictive roots and stems crush and kill the same trees that help them get above the forest canopy.

Such behavior needs to be considered when selecting vines for home gardens. Bulky and potentially constrictive wisteria vines that would tear lattice apart can be quite appealing on sturdy arbors or trellises. Lattice could instead be adorned with docile Carolina jessamine, lilac vine, mandevilla or even regularly pruned passion vine. Star jasmine and the various trumpet vines work nicely to obscure chain link fences. With regular selective pruning, pink jasmine, honeysuckle and potato vine work well on rail fences.

Climbing roses and bougainvillea do not climb on their own, but can be trained almost like vines. Some varieties stay small enough for low fences and trellises. Larger types are proportionate to larger fences and arbors.

Horridculture – High Fences

It is unfortunate that, regardless of the excellent climate and excellent soils, such minimal space within the Santa Clara Valley remains conducive to gardening.

tonytomeo's avatarTony Tomeo

P90522There is no doubt that fences are useful for a variety of functions. They exclude deer from the garden. They confine livestock. For suburban homes, they enclose a relatively safe space for children and pets. Fences should be designed according to their intended functions. Those designed to exclude deer might be as simple as coarse mesh on posts. Those enclosing backyards might be more refined and compatible with the landscape.
Over the years, conformity to modern suburban and urban landscapes, as well as modern architecture and lifestyles, has changed the standards of how fences are designed. Low picket fences do not adequately obscure the scenery that adjacent and often dissimilar landscapes contribute to a view. Where common vegetable gardens might have been, most of us want private outdoor rooms, with a distinct style of landscape.
It seems that everyone wants privacy nowadays. Those who have no need for privacy will…

Hopbush

Hopbush makes a nice small tree.

Johnny jump up and jumping cholla have no more than amusing names in common with hopbush, Dodonea viscosa. Neither a dangerous cactus nor a docile annual, hopbush is an elegantly upright and evergreen shrub. It is very popular for both informal and formally shorn hedging. With pruning, it can become a small tree with handsomely furrowed bark.

Hopbush has potential to get about as tall as a two story house, particularly with pruning for tree form. Conversely, with only occasional pruning for hedge form, it is just as happy to stay just six feet tall. Trees with single and straight trunks fit nicely into narrow spaces. Trees with a few irregular trunks that lean outwardly are more sculptural for larger areas.

The narrow evergreen leaves are about two or three inches long, with light bronzy color. ‘Purpurea’ has purplish bronze color, but does not grow as vigorously. Most hopbush are female, and generate interestingly papery seed. Bloom and seed production are variable though, and some specimens become male. Roots should be complaisant with concrete.
