Addendum

This old article explains why my involvement with the big valley oak that I shared pictures of yesterday is so limited.

p90105kThere is much more to the landscapes at work that I wrote about earlier this morning at https://tonytomeo.com/2019/01/05/six-on-saturday-cabin-fever/ . Otherwise, my job would be quite boring.

I do not climb big trees; so any work that the redwoods need must be done by someone else. The big redwoods, as well as the ponderosa pines, Douglas firs and various oaks, are of course the most prominent and memorable features of the landscapes. There are also a few other exotic trees that were added to the landscapes years ago. My primary work with those that have grown beyond my reach is identifying problems for other arborists to correct or remove.

However, there is plenty at ground level to keep us very busy.

Our landscapes are simple and somewhat unrefined. They take as much work as they do because they are so big and dispersed over a large area. There seems to be…

Windows Of Heaven

Goodness; this really complicates a simple and potentially artistic picture.

tonytomeo's avatarTony Tomeo

P81229KOr . . . a close encounter of the third kind. Let’s just go with the former rather than the latter.

I am no photographer. The pictures that I post are merely illustrations for articles from my gardening column, and other articles. This picture just happened to make itself available while I was getting the first of the six pictures of the earlier ‘Six on Saturday’ post. The location is nothing special. It is not really out in the forest like it seems to be. A lodge building of six suites is directly to the left. A big ‘housekeeping’ building is to the right. There is a road in the background above, as well as below, from where the picture was taken.

Even the flora in uninteresting. The most prominent straight trunk in the middle is that of a young Douglas fir. The slightly leaning trunk with upward reaching branches…

Six on Saturday: HAPPY NEW YEAR!

HAPPY NEW YEAR!

Happy January too! Happy Saturday! Really though, what is all the fuss about? There is nothing new about this. New years have been arriving annually for as long as anyone can remember. New days arrive daily. New hours arrive hourly. In fact, a new one just began within the last sixty minutes or so. Perhaps that justifies trying to be happy whenever we want to. I digress. My Six for this Saturday are irrelevant to this New Year, and actually, are not exactly happy. All six pictures involve just two trees, a valley oak, Quercus lobata and a coast live oak, Quercus agrifolia.

1. Thunderstorms are rare here. A real doozy arrived on Christmas morning though. The wind could have landed Rhody in Oz. This distinguished valley oak lost two major limbs. 

2. The worst of the damage is just above and slightly left of the center of this picture. The large limb that fell from there clobbered another large limb that was closer to the center.

3. Can you identify what this picture shows? The pair of short yellow lines near the lower center of the picture is a clue. That is the dirty tip of my left boot in the lower left corner. 

4. Tilting the camera from vertical reveals why I could not return to work after what was supposed to be a quick errand. This large coast live oak fell and totally blocked the road.

5. But wait, there’s more! This was more than we could move efficiently with the tractor. Two crews, working at both ends, took all day to clear it all. Another trunk fell to the left. 

6. The trunks had been deteriorating for decades. The moisture of the adjacent drainage ditch accelerated rot. All that evergreen foliage finally got too heavy when wet from rain.

Chinese Evergreen

With such lush foliage, Chinese evergreen is a bold houseplant alone, and is also quite compatible with all other houseplants.

It is no coincidence that Chinese evergreen, Aglaonema, is perhaps the most common tropical plant for interiorscapes. It is quite easy to care for, and available in so many unique personalities. Many have rich deep green foliage. Most are elegantly variegated with white, silvery gray or gold. Leaf shape is quite variable, although most have rather narrow leaves radiating outward from dense rosettes. Leaves can be half a foot to more than a foot long, and a bit more than an inch to almost six inches wide. Mature plants are at least a foot tall and a foot and a half broad.

Indirect sun exposure or partial shade is best. Chinese evergreen likes humidity, so likes to share sheltered enclosed atriums with other lush foliage plants. New plants are easy to propagate by division.

Get Bare In Winter

Besides the popular deciduous fruit trees and roses, several deciduous ornamentals, like these clematis vines, are also available bare root.

It may not seem like the middle of winter is a good time for much gardening, but now that any unsold Christmas trees have been removed from nurseries, bare roots plants are moving in. They should be available through the rest of winter, until warming spring weather prompts bloom and emergence of new foliage.

As the name implies, ‘bare root’ plants have bare roots. They are not contained within potting media (soil) in cans or pots. Some are wrapped in coarse sawdust to keep roots moist and contained without much weight. Others are simply heeled into damp sand at nurseries where they can be dug and wrapped when purchased.

Without cumbersome cans, bare root plants occupy less space in nurseries, so many more varieties of fruit trees, grapes, roses, berries and various ornamentals can be available bare root than could be available as standard canned stock during the rest of the year. Bare root plants have the added advantage of costing about half of what canned stock costs.

The main advantage of bare root plants though, is that they waste no time getting established in the garden. The process of getting dug, transported and replanted is done while plants are dormant. When they wake in their new homes in the spring, they immediately start to disperse new roots into the surrounding soil.

If bare root plants can not go directly into the garden once they arrive home, they should be heeled into damp soil or mulch and watered. If planting will be delayed only for a day or two, they can instead be put in a bucket of water to submerge the roots. Plants that are packaged in bags of damp sawdust can wait for more than a week in the shade.

Planting holes need not be any larger than the roots of the bare root plants. If soil is disturbed too deeply, it will only settle and possibly cause new plants to sink. Graft unions (which are evident as kinks low on trunks of trees, or where rose plants branch) should stay above the surface of the soil. Backfill soil should be amended only minimally, or not at all. Too much amendment inhibits root dispersion. (Roots may not want to leave amended soil.) There will be plenty of rain through winter. However, new plants should be soaked twice after planting to settle soil around the roots.

Finally, damaged or unnecessary stems can be pruned off. Bare root fruit trees come with more stems than they need, for padding in transportation, and to allow more options for pruning.

Horridculture – Clearance

After three years, the Italian stone pines in the illustration are in no better condition.

tonytomeo's avatarTony Tomeo

P90102Many arborists mark certain lengths on their pole saws and pole pruners. When stood upright, these marks designate the standard heights for minimal clearance pruning. Not so many need to mark the height of minimal clearance for walkways, since they will prune away anything that is within reasonable reach with hand tools from the ground. The minimal clearance above parking spaces is not so easy to guess at, so is more likely to be marked on poles. So is the minimal clearance over roadways, where the lowest limbs must be high enough to be out of the way of campers and freight trucks.
Clearance to the sides is determined by the location of the curb, but even that might need to be modified at sharp turns, or where the roadway slopes significantly away from the center. Clearance must similarly be a bit higher over dips in a roadway, where the…

Persimmon

Ripe persimmon is surprisingly sweet.

Most other deciduous fruit trees provide delightfully profuse spring bloom as well as fruit. Persimmon, Diospyros kaki, does not. It compensates though, with brilliant orange foliar color for autumn. Defoliation reveals comparably bright orange ripe fruit. The awkwardly bulky fruit may look silly on lanky limbs of otherwise bare trees, but they sure are yummy! 

Persimmon trees will not require a pollinator to generate an abundance of fruit. However, according to some experts, paired trees of different cultivars produce more abundant fruit of slightly better quality. Abundance is not necessarily an asset though. Unfortunately, all that very perishable fruit ripens at the same time. Fruit is inedible before completely ripe.

Mature persimmon trees can get big enough to become moderate shade trees. If they do, their abundant fruit will be too high to reach, and will generate a horrendous mess when it falls. Although they are handsome trees, they should probably stay relatively short and compact. New trees should be planted while dormant during winter, preferably bare root.

Dormant Pruning Promotes Fruit Production

Persimmon trees get pruned after harvest.

While they are dormant through winter, deciduous fruit trees require specialized ‘dormant pruning’. Exceptions are rare. Most need major pruning that might seem to be excessive. Without such pruning, fruit trees produce more fruit than they can sustain. Excessive fruit is very likely to be of inferior quality, beyond reach, and heavy enough to disfigure limbs.

Dormant pruning limits the volume and weight of fruit that can develop during a following season. By eliminating structural deficiencies and maintaining compact form, it improves the structural integrity of trees. It eliminates diseased stems, and concentrates resources into healthy stems. Dormant pruning concentrates resources into less but better fruit too.

Dormant pruning is necessary because of extensive breeding to improve the quality and quantity of fruit that fruit trees produce. The ancestors of modern cultivars of fruit produce either smaller or less abundant fruit that they can generally support in the wild. However, even some wild fruit trees will produce better fruit with pruning to concentrate resources.

The many various types of fruit trees need various types of specialized dormant pruning. Unfortunately, such trees, which are so commonly available from nurseries, do not come with instructions. It is important to be aware of the sort of maintenance any particular fruit tree will require, prior to incorporating it into a garden. Some dormant pruning is extreme! 

The various stone fruits are the most popular deciduous fruit trees. They are of the genus ‘Prunus‘. Their fruits contain single large seeds, or ‘stones’. This includes apricot, cherry, nectarine, peach, plum, prune, almond and all their hybrids. They need the most intense dormant pruning. (Almond nuts are stones of leathery fruits that are the hulls of the nuts.)

Although uncommon within the mild coastal climates of Southern California, pome fruits, primarily apple and pear, are very popular too. They require specialized dormant pruning that is very different from what stone fruits need. Likewise, persimmon, pomegranate, fig, mulberry, currant, kiwi, grape and cane berries, each need customized dormant pruning.

Winter

Since the date today does not coincide with the date on which this article posted three years ago, it is now five days into winter instead of two as prefaced in this article.

tonytomeo's avatarTony Tomeo

P80110We are now two days into it. Is it any different than three days ago, the last day of autumn? Not really. Even in harsher climates, the changes from one season to the next are gradual. Like the phases of the moon, the seasons are constantly phasing out of the previous, and into the next. The dates of the first and last days of each season, which are determined by the position of the Earth within its orbit around the sun, are technicalities.
Seasons in the Southern Hemisphere are of course opposite of what they are here. That seems odd to me. The calendar is the same there as here. It seems obvious to me that winter and all seasons should be determined by the same dates there that they are determined by here. If winter began last Friday here, it should have done the same there, on the the…

Electric Snow

What is a white Christmas ‘really’ all about?

tonytomeo's avatarTony Tomeo

P81230It was one of the more common types of snow in the Santa Clara Valley in the early 1970s.
In school, we made paper snow by folding paper squares in half and then into thirds (so that they were folded into sixths), and then cutting notches and slices out of them. They unfolded into the prettiest and laciest snowflakes!
In Westgate Mall, snow was blown by small fans about the new models of Singer sewing machines that were magically suspended in big acrylic spheres. We children could not get into the spheres, so were left wondering if the snow within was as cold and wet as we were told it was, and why it was necessary to demonstrate that the new sewing machines were resistant to weather. Our mother did her sewing inside.
We sort of suspected that the snow around the Nativity at Saint Thomas of Canterbury and other…
