Coppice To Renovate Overgrown Shrubbery

Coppicing stimulates vigorous new basal growth.

Pollarding is extreme pruning. It removes all but the most substantial of limbs and trunks. Coppicing is even more extreme. It leaves only stumps above ground. Both are common and respected arboricultural techniques outside America. However, they are vilified here. Actually, very few arborists here know how to pollard and coppice properly, or admit to it.

There are many valid reasons to pollard or coppice trees or big shrubs. Both techniques stimulate vigorous growth. Lush foliage of such growth is useful as fodder, particularly for silkworms. Elongated stems of such growth are useful for basketry and kindling. Species that bloom on older stems can not produce pollen or messy fruit after annual procedures.

Although silkworms, basketry and such are unimportant within an average home garden, proper pollarding or coppicing enhances vigor. This enhances the bloom of species that bloom on new stems. Vigorous growth of pollarded crape myrtle is atypically resistant to mildew, and also blooms zealously. Coppice pruning eliminates unsightly thicket growth.

Pollarding is generally useful for trees and large shrubs that retain primary trunks. Only a few of the many species that inhabit home gardens are conducive to it. Since secondary growth is initially structurally deficient, it will most likely need subsequent pruning during subsequent winters. Some vigorous pollarded trees are dependent on annual pollarding.

Coppicing is generally useful for large and vigorous shrubbery, and perhaps a few types of trees. Coppiced shrubbery is not as reliant on subsequent pruning as pollarded trees. They either benefit from pruning as they grow anyway, or do not get too heavy to support their weight. Both coppice and pollard pruning can happen only during winter dormancy.

Realistically, the majority of plants in home gardens are conducive to neither coppice nor pollard pruning. Cypress hedges die if cut back to stumps. Grafted plants, even if pruned above their graft unions, are likely to regenerate from their understock. However, some of the most popular hedge plants, such as privet, holly, photinia, osmanthus, English laurel and bottlebrush regenerate splendidly.

Junk In The Trunk

It is exactly what it looks like; more Canna rhizomes. I am very aware that there are already too many Canna here. I grew them. I do not care. I saw these in a neighbor’s garden, and asked for a few copies. She told me that I only needed to dig them myself, as if that might be a problem. As she pointed out those that were migrating a bit too close to her home, I dug many more than I should have. Since she was so generous to share so many, I felt obligated to remove all that were superfluous. Besides, to me, they are not junk. I am very pleased with them, even if they are a bit excessive.

There are two cultivars, and perhaps seed grown rhizomes of one of the two cultivars. The shorter sort are ‘Inferno’, which is the same as ‘Tropicanna’ and ‘Durban’. Some Canna cultivars seem to develop several synonyms. Its bright orange bloom stands tall above distinctively striped and bronzed foliage. It gets about six feet tall, so is only the shorter of the two cultivars because the other is so much taller. Although it is one of the more popular cultivars, I only recently acquired a single can of it from Brent last year. I am pleased to grow much more.

The other cultivar seems to be comparable to the unidentified cultivar at work that resembles and might actually be Canna musifolia. It has similar scrawny orange bloom on top of very tall canes that I must bend over for deadheading. Because I did not notice them until after frost, I do not know how bronzed the foliage is, or if it is bronzed at all. The neighbor who gave them to me says that they are ‘lightly’ bronzed. The newly emerging buds seem to be green without any bronze. I will be pleased with any color, but simple green would be awesome! Some of these may have grown from seed, so may be slightly different from the original.

There were enough rhizomes of ‘Inferno’ for a dozen #5 cans with about four rhizomes each. There were enough rhizomes of the taller sort that might be Canna musifolia for sixteen #5 cans with about three very plump rhizomes each. That was after sharing some with others at work, and leaving some for a neighbor of the neighbor who shared them with me. I intend to take some to the Pacific Northwest before the end of winter, but canned them all because I do not yet know when I will leave. I can always remove some from their cans, or just take them in their cans.

Since they fit into the trunk more easily than a previous batch of ‘Wyoming’ and a cultivar that resembles Canna flaccida that I obtained from another neighbor, they seemed to be less numerous. However, the previous batch included foliage. These rhizomes lacked foliage, and were actually a bit more numerous. Regardless, I am very pleased with them, and intend to enjoy growing them. As I closed the tailgate after unloading them, I could see that Rhody did not share my enthusiasm.

If A Tree Falls In A Forest . . .

If a tree falls in a forest of the tallest species of tree in the World, things might get messy. Understory trees often fall without much commotion, but the demise of this particular redwood was observed from all over the neighborhood. The forest that it inhabited is too crowded for good pictures of where it landed. I got what I could. Falling trees is one of the unpleasant and hazardous results of the recent epically abundant rain.

About twenty feet of trail dislodged with the massive root system that nearly inverted as it fell into the canyon below. The gap was less than fifteen feet long on the left and uphill side of the trail when this picture was taken, but widened as more soil collapsed into the muddy void below. Obviously, the trail is now closed. Repair is not a priority until after winter at the soonest.

The dislodged root system is about thirty feet wide. I did not estimate how far into the canyon it slid. Since I can not see the base of the trunk, I did not estimate how wide it is. The trunk extends diagonally to the right, where it is obscured by vegetation in the foreground. It broke many other trees as it fell, leaving the shattered trunks and limbs that are visible to the upper right and left. Some of the debris near the water was deposited by earlier flooding.

The trunk fell upstream into a curve in Bean Creek below, so almost crossed the creek twice. From this distance, it is difficult to estimate the width of the trunk. Because the top is not visible, it is impossible to estimate the height. If it did not burn up in the atmosphere, someone in Nevada might have received an unexpected delivery of lumber.

Six on Saturday: Excuses

It had not rained so much here since 1982. Consequences of such excessive rain were the priorities at work. I neglected to procure pictures of horticultural topics while the first of the problems associated with the weather began to develop two weeks ago. I was unable to transmit new pictures last week because of disruption of telephone service. Now that I am able to share new pictures, I find that a few are redundant to some that I posted two weeks ago, and none are any more horticulturally oriented than a few unidentifiable logs and an unseen redwood tree. Well, at least they demonstrate why I was too busy to share horticultural pictures on Six on Saturday.

1. Mudslides blocked a few portions of the main road into town at various times. None of them stayed for long, but they took turns. Shortly after one got cleared, another one slid.

2. Sinkholes were mudslides from below rather than from above, and ruined portions of roads that were not under mud. I nearly dropped the camera here to hastily grab Rhody.

3. Floods got deeper than since 1982, and took trees that were big enough to leave twigs two thirds of the way up the right and upstream side of the pillars nearest to the middle.

4. Logjams collected some of those trees that would otherwise be on beaches near Santa Cruz by now. Ironically, that is a municipal water pumping station across Zayante creek.

5. Fallen trees are particularly dangerous within forests of the tallest trees in the World. This one took out about twenty feet of the trail. I will share two more pictures of it later.

6. Rhody was exhausted from exemplary service to his similarly exhausted crew through many days of the rainiest weather here since 1982. He is enjoying sunnier weather now.

Grecian Bay

Grecian bay does not get as massive as the native bay laurel.

The native bay laurel should not be confused with the Grecian or sweet bay. Despite the similarities, the native bay laurel grows into a large tree. The foliage can be used as seasoning like Grecian bay, but has a very different and much more pungent flavor. It can often be found fresh in markets, labeled as Grecian or sweet bay, and has likely ruined all sorts of recipes.

Grecian or sweet bay,  Laurus nobilis, stays much smaller much longer. It takes many years to grow to thirty feet tall, often with many trunks flaring out from the center. Trees that are nearly twice as tall are ancient. Because of slow growth, Grecian bay can be happy in large containers as long as it is pruned to stay proportionate to the confined root system.

The three or four inch long, and inch or so wide leaves of Grecian bay can be difficult to distinguish from those of bay laurel. The minor differences are that Grecian bay leaves have slightly undulate margins with a few small and sometimes barely perceptible serrations (teeth) that bay laurel lacks. The leaf apexes of Grecian bay leaves are typically a bit more blunt. For culinary purposes, it is important to be aware that dried leaves and fresh leaves have very different flavors.

Deciduous Fruit Trees Need Specialized Dormant Pruning.

Apple and other pomme fruit trees are pruned very differently from stone fruit trees.

It seems unfair that so many deciduous fruit trees are available without warnings that they need such specialized maintenance. They are certainly worth growing. Otherwise, not many of us would grow them. Yet, those of us acquiring fruit trees for the first time should be aware that, with few exceptions, deciduous fruit trees need specialized and meticulous pruning while dormant every winter.

The pruning these trees require is too specialized to explain in a few short paragraphs; but can be researched for each particular type of fruit tree. Sunset publishes an excellent book about ‘Fruit Tree Pruning’, that illustrates and explains the different types of pruning that each different fruit tree needs. Pruning is the sort of thing that gets better with experience; so even though the pruning gets more involved over the years as the trees grow, the procedure becomes more familiar.

Without pruning, deciduous fruit trees produce more fruit than they can support, which disfigures and breaks branches as the fruit matures and gets too heavy. Even if limbs do not break, overabundant fruit is often of inferior quality because the trees that produce it exhaust their resources. Fruit of well pruned trees may not be as abundant, but is typically better. Besides, pruning is good arboricultural hygiene, keeping trees vigorous and more resistant to disease.

The stone fruits probably need the most severe pruning. These are fruits like apricots, plums, prunes, nectarines and peaches, that have hard pits or ‘stones’. They develop fruit on stems that grew during the previous year. Generally, these stems need to get cut back short enough to support the weight of the fruit that will develop in the next season. Dead, dying, damaged and diseased stems, known as the four ‘D’s, should be pruned out completely.

Cherries and almonds are the exceptions to the generalization about severe pruning for stone fruit, since the trees can support the weight of the fruit. They only need pruning to eliminate the four ‘D’s and to limit height. Because almonds get shaken from their trees instead of picked, they are often allowed to get quite tall, and can even function as small shade trees. Peaches are the opposite extreme since their fruit is so large and heavy, necessitating the harshest pruning.

Pomme fruits like apples and pears need similar but somewhat different pruning, which preserves stunted ‘spur’ stems that produce fruit low on older stems for many years. Like cherries, certain pears may not need much pruning. Certain apples need more pruning than others. Again, the needs of particular trees are best learned from experience.

Horridculture – Memorials

Oh, this one is especially offensive.

tonytomeo's avatarTony Tomeo

P00129 Where are the cedars?

Memorial trees should be remembered . . . right? I mean, they are planted to remind us of . . . something, or . . . someone. They are typically trees that will be around for a long time, because that is how important memories should be. Redwoods and oaks work nicely. Most get outfitted with plaques to remind everyone what the trees are there to remind us of.

The old original Sunnyvale City Hall was landscaped with several memorial trees. The most prominent were redwoods and cedars that were mostly planted as memorials for local veterans of various wars. They accumulated over several decades and a few wars. City Hall seemed like a good place for them, where they could live for a long time without bother.

However, City Hall was demolished in the late 1970s, and replaced with a big mall. The larger redwood…

Kalanchoe

Kalanchoes bloom with tropical fruity color.

Even if never as overly indulgent in bloom as when new, Kalanchoe blossfeldiana is one of the more sustainable of popular blooming florist plants. Forced bloom remains colorful for quite a while. By the time it deteriorates enough to necessitate grooming, new foliage may already be developing. Sporadic subsequent bloom is more natural in appearance.

Ultimately, Kalanchoe blossfeldiana becomes more of a succulent foliar houseplant that occasionally blooms, rather than a spectacular floral plant. Individual plants may survive for only a few years, but are likely to generate basal pups that grow as new plants during that time. Also, they are very easy to propagate by succulent stem and even leaf cuttings.

Mature Kalanchoe blossfeldiana do not get much more than a foot high and wide. Some may stay half as tall. Their lower leaves can get three inches long, with crenate margins. Minute yellow, orange, red, pink or creamy white flowers bloom for late autumn or winter. Garden plants require shelter from chill through winter and hot sunlight through summer. Most are houseplants that appreciate copious sunlight.

Forced Bloom Is Not Sustainable

Moth orchids are grown for bloom.

Poinsettias are very popular blooming potted plants for about a month prior to Christmas. Then, most quietly disappear prior to spring. A few become foliar houseplants. Fewer go into home gardens to likely succumb to frost or neglect. Very few survive for more than a few years. It is not easy to recover from the procedures that forced them to bloom so well.

Forcing bloom is stressful. It provides unnaturally indulgent doses of stimuli that optimize floral performance. It involves any combination of deceptive environmental and chemical manipulation. Optimal bloom is the primary objective. Sustainability or even survivability after bloom is irrelevant. Forced plants are barely more than cut flowers with potted roots.

For example, poinsettias receive much more than the nutrition they require for exemplary growth and bloom. The greenhouses that they grow in maintain optimal temperature and humidity for them. Shading shortens their daylength to deceive them into believing that it is the season for bloom. Transition from such decadence to natural conditions is difficult.

Almost all fancy blooming potted plants that are available from supermarkets and florists, and several from nurseries, are forced to some degree. These include poinsettia, orchid, chrysanthemum, hydrangea, azalea, a few types of roses and various bulbs. Such bulbs include lily, narcissi, crocus, hyacinth and tulip. Some exhaust their resources by bloom.

Many forced plants are cultivars that are distinct from more common landscape cultivars. For example, many florist hydrangeas bloom with huge and very abundant floral trusses on short stems. They are spectacular in pots, but might not be so practical for landscape situations. Landscape hydrangeas support bloom higher over the ground on taller stems.

Their potential for inferior performance after their potentially difficult recovery from forcing should not necessarily disqualify forced plants from salvage. Short florist hydrangea can be delightful accessories to bigger landscape hydrangea. Moth orchids are impressively adaptable. Premature doubting of possible ultimate results can be more effort than trying.

Corm-ucopia

Since posting this recycled article, I actually procured a few copies of my first Montbretia that I found growing wild in Montara in the early 1980s, and did so ‘intentionally’. Furthermore, I canned a few copies of the Montbretia that grows in the downtown planter box, just in case I want to put them somewhere else.

tonytomeo's avatarTony Tomeo

P00119 Is this part of the secret to their success?

Montbretia showed up here several years ago. Of course, it did not take long for it to get very established. It is too shady for bloom, but not shady enough to inhibit vegetative proliferation. Those nasty stolons get everywhere, and grow into corms. They are so aggressive that they exclude English ivy! Seriously, they are the only species we know that can crowd out English ivy!

Some consider Montbretia to be the the genus name. Some consider it to be a common name for the genus of Crocosmia, or for a particular intergeneric hybrid. What is now so aggressively naturalized here might be Crocosmia paniculata. I really do not know. The few rare and sporadic blooms look like what I am familiar with in other landscapes, with branched inflorescences.

Now, I am aware of how aggressive their stolons are…
