Invasive Exotics – Acacia dealbata

Perhaps this recycled article should have been scheduled for the ‘Horridculture’ theme on Wednesday.

tonytomeo's avatarTony Tomeo

P80211Every invasive exotic (non-native) species has a story of how it got here.

Blue gum and red gum were imported to produce the timber needed for railroad ties. Many annual specie were forage crops for grazing cattle. Some got here by stowing away as seed on or inside cattle or other animals. Supposedly, mustard seed was broadcast by those traveling on the El Camino Real so that other travelers could find the route later. Then there are all sorts of invasive exotics that were imported simply because people liked to grow them in their gardens.

It is difficult to imagine why anyone would import any of the weedy specie of broom (Genista specie) or the sloppy species of pampas grass (Cortaderia jubata). It might have made sense at the time, before more appealing specie were introduced, or before less invasive modern cultivars were developed. Black locust has…

Ecclesiastes 3: 1

According to Ecclesiastes 3:1, “There is a time for everything.” Unfortunately, this is still not the time for me to write new articles, which is why I continue to recycle old articles such as this.

tonytomeo's avatarTony Tomeo

P80207There is a time for everything, and a season for every activity under the Heavens:

Verses 2 through 8 continue to list a few examples of more specific activities that happen at specific times. If there were more examples, autumn foliar color would probably be cited as well. After all, autumn foliar color happens in . . . well, . . . autumn.

Perhaps it was omitted for brevity. Of course, there is the possibility that it was omitted to avoid confusion. If it had been cited, it might have been described simply as ‘foliar color’ rather than ‘autumn foliar color’. Some foliage colors earlier if distressed. Some foliage does not color until frosted. Some might even delay color until it is in the process of getting replaced by new foliage. Then there are the many sorts of evergreen foliage that do not color at all, or at least in…

Six on Saturday: Do you know the way to San Jose?

Rhody and I needed to go to San Jose for the past three days, and will be going there again at least until April. We had not been there or even into the Santa Clara Valley for a very long time. I did not realize how long we had been gone until I collected my accumulation of mail on the way through town, and found Christmas cards!

1. Tecoma stans is the second most important topic of my Six for this week! The Shrub Queen sent me these seed from wild plants that are native to Southern Florida! It is so rare here that I had seen it only a few times prior. A compact cultivar became available only a few years ago. I wanted the straight species. Embarrassingly, these seed were in my mailbox since December.

2. Camellia japonica is still blooming, with buds that will continue even longer. Technically, it is not late. Some bloom as late as March. I do not remember the name of this particular cultivar.

3. Ribes sanguineum is native to the forests only a few miles from here. This one and another like it were planted here a few years ago. Two others that bloomed white did not last very long.

4. Narcissus pseudonarcissus, or simply ‘daffodil’, bloom sporadically in the oddest of situations. Their bulbs remained where they got planted years ago, as the landscape changed over them.

5. Spirea prunifolia ‘Plena’ is sparsely branched, but perhaps delightfully so. I am surely no expert in regard to aesthetics, but it seems to me that more profuse bloom would be less delicate.

6. Rhody is the most important topic of my Six for this week. This was the moment immediately prior to his realization that I was aiming the camera at him, and his spry reaction to avoid it.

This is the link for Six on Saturday, for anyone else who would like to participate:

Daphne

Perhaps fragrance could be more colorful.

The small trusses of tiny, pale pink flowers of daphne, Daphne odora, really do not need to be too flashy with such powerful fragrance. Actually, the flowers might be considered to be less interesting than the glossy evergreen foliage. The most popular cultivar, ‘Marginata’, has a narrow ivory or pale yellow edge to each leaf. Each leaf is only about two or three inches long. Each domed flower truss is about as big as half of a ping pong ball. Daphne is sometimes grown to compliment and provide fragrance for boldly colorful but fragrantly deficient camellias.

Daphne is unfortunately notorious for being somewhat finicky. It likes rich soil and reasonably regular watering, but quickly rots if soil stays too damp or drains inadequately. The roots are quite sensitive to excavation. Partial shade is no problem. Yet, even the biggest and happiest specimens do not get much more than three feet high and five feet wide, and rarely live more than ten years. Daphne is toxic, and the sap can cause dermatitis.

Blossoms Bloom Sooner If Forced

Stems of tiny blossoms really impress.

Pussywillow is an odd cut flower. It is neither fragrant nor very colorful. It just gets cut and brought into the home because the distinctively fuzzy catkins are so interesting. They are appealing alone or mixed with other late winter flowers. The otherwise bares stems can get cut just as soon as the fuzz is beginning to become visible within the swelling buds. Bloom accelerates once the cut stems are brought into a warm home.

There are actually several other plants that can provide bare twigs that can be ‘forced’ into bloom in the home. ‘Forcing’ is simply the acceleration of bloom of such twigs by cutting them and bringing them from cool winter weather into warm interior ‘weather’. Flowering quince, flowering cherry and flowering (purple leaf) plum have likely finished bloom; but forsythia, hawthorn, flowering crabapple and many of the various fruit trees that have colorful bloom will be ready to be forced any time. Some daring people even force redbud, dogwood, witch hazel, lilac and star and saucer magnolias.

When the deciduous fruit trees that bloom well need to be pruned in winter, some people intentionally leave a few spare branches to be cut and forced later, just before bloom. These include almond, cherry, apricot, plum, prune, nectarine, peach, pear, apple and a few others. When stems get cut for forcing, they should be pruned out from the trees according to proper dormant pruning techniques, and can be trimmed up accordingly when brought into the home. Flowering (non-fruiting) trees should likewise be treated with respect when stems for forcing get pruned out.

Twigs to be forced should be cut just as the flowers are about to bloom, and preferably, as a few flowers are already blooming. They should be put in water immediately, and if possible, cut again with the cut ends submerged. Buds that will be submerged when the stems are fitted into a vase should be removed.

Once in a warm home, the rate of bloom will be accelerated, although everything blooms at a particular rate. Apple and pear bloom later than most, and can bloom slow enough to justify cutting stems while already blooming. As forced stems bloom, they can be quite messy, but the mess is probably worth it.

Sesame Street Was Wrong!

Horridculture is worse when I can not blame someone else for it.

tonytomeo's avatarTony Tomeo

P71231It was probably one of the best television shows for children back then, and probably still is. Everyone of my generation in American remembers Sesame Street. We all identified with it, even if our neighborhood did not look like Sesame Street, or lacked the variety of neighbors. Sesame Street sometimes took us on television field trips to other neighborhoods. Some were more familiar. Those that were more foreign were presented within a compelling and inviting context that got us interested in how other children lived within their respective societies.

Some kids lived in big cities and rode on buses. Others lived in suburban areas with big gardens. Some lived on farms with hens and cows. There were even kids who lived near a forest surrounded by big tall evergreen trees. The trees were probably the firs, spruces and hemlocks of New Hampshire. I do not remember. I just knew I…

Norway Maple

Few maples perform as well here.

Japanese maples get all the notoriety. They have such delightful texture and form. Many are proportionate to small spaces, such as atriums. Realistically though, they are overrated and overused. Meanwhile, other maples that work as larger shade trees remain obscure. Norway maple, Acer platanoides, gets broad enough to shade much of an urban garden, but rarely gets to forty feet tall.

Of course, Norway maple has innate limitations. It dislikes arid and harshly warm desert climates. Nor does it like to be too close to the coast. Los Angeles is about as far south as it wants to live. In the Pacific Northwest, it gets much bigger, and develops greedy roots. The non-cultivar species is invasive there. Norway maple defoliates neatly for winter, but then refoliates late in about April.

Almost all local Norway maples are cultivars. ‘Schwedleri’ has richly bronzed foliage. It is rare now, but was a popular street tree in the 1950s. ‘Crimson King’ has richer purplish foliage, but is less vigorous. ‘Drummondii’ displays delightful variegation. The deciduous foliage of Norway maple turns soft brownish yellow or gold for autumn. The palmately lobed leaves may be five inches wide.

Coppicing And Pollarding Annoy Arborists

Pollarding is a long term commitment.

Coppicing and pollarding are the most extreme of pruning techniques. They may also be among the oldest in some cultures. Yet, arborists are correct to condemn both as improper. Coppicing is the complete removal of all stems and trunks back to a stump. Pollarding is the removal of all stems back to main stems and trunks. Both procedures happen in winter, annually or every few years.

Both coppicing and pollarding stimulate vigorous and prolific cane growth during the next season. Lush foliage of such growth is useful as fodder. Foliage of pollarded mulberry is the primary food of silk worms. Canes are good kindling for the following winter. Thin canes of various species are useful for basketry. New foliage of pollarded eucalypti is useful for both essential oils and floristry.

Of course, few rely on modern urban gardens for fodder, kindling, eucalyptus oil, or basketry material.

Arborists disapprove of coppicing and pollarding because both techniques ruin trees. Many of such trees are too structurally compromised to support the weight of secondary growth after the first year. Consequently, they rely on annual coppicing or pollarding. Some trees will support their weight for a few years. Strangely though, many properly coppiced or pollarded trees live for centuries.

Coppiced trees generate from stumps of cut down trees. Ideally, they begin young. Grafted trees are less cooperative. They are likely to generate suckers below their graft unions. Pollarded trees get to develop their main trunks and limbs prior to their first pollarding procedure. The locations of the first pollarding cuts is very important. Subsequent pruning will be back to the same locations.

Distended ‘knuckles’ develop after repeated coppicing or pollarding back to the original pruning sites. Pruning must be flush to these knuckles. Stubs interfere with healing. Annual pruning leaves smaller wounds than less frequent pruning. Secondary growth should be able to overgrow wounds efficiently. Cutting below knuckles leaves wounds that may be too big to heal before they decay.

Weather To Die For

This recycled article is not exactly accurate for current weather conditions elsewhere, but describes the current weather here. It does not happen every year, but is somewhat common.

tonytomeo's avatarTony Tomeo

B80210KDon’t worry. He is not really deceased. He is just making good use of the lawn. The well foliated trees in the distance are a clue that this pictures was not taken recently, although it illustrates the current weather conditions accurately. We all want to be out in it, whether getting lazy in a local park, walking on the beach, or just staying home and working in the garden.

It seems that almost everyone else is contending with less pleasant weather. The summer in much of Australia had been historically hot. Much of Europe got some nasty storms. Parts of the Southeastern United States of America that get snow only on rare occasion got more than they have in recent memory.

We are certainly used to our share of pleasant weather through winter. We can only see snow in the distance on top of Mount Hamilton. Frost only happens a…

If you want your garden to grow, you have to talk to it.

Sadly, the not so little Monterey pine in the old school yard is now gone. Unfortunately, they do not last long in the chaparral climate of the Santa Clara Valley.

tonytomeo's avatarTony Tomeo

P80131So the spelling is a bit . . . off. Ignore the ‘E’ before ‘If’ and the ‘n’ after ‘grow’. They are crossed out . . . sort of. ‘wont’ means ‘want’. ‘haf’ means ‘have’, as in ‘have to’ or ‘need to’. It made sense at the time, more than four decades ago. Perhaps I should rephrase it.

If you want your garden to grow, you must talk to it.

You must talk to your garden in order for it to grow.

Your garden requires regular discourse for healthy growth.

This concept dates from a time of big Boston ferns and spider plants suspended by coarse macrame with big wooden beads. Coleus and rubber tree were popular house plants too. Remember terrariums? There were big flowered daisies, tam junipers and big petunias in the yard. A group of three European white birches was cool, as if it was somehow unique…
