Six on Saturday: Gophers and Weeds

 

Both have been very active all spring. Some of the sneakiest have been getting away with their activity unobserved.

1. This is a fifteen foot tall camellia, or what remains of it. For comparison, that is a six foot long bench it is laying on. It still looks green and healthy, but started leaning. Upon closer examination, I found that it was not rooted to the ground. It pulled right out! The roots were almost completely gone! There was no indication that there was a problem.P90615

2. This is what remained of the root system. Gophers ate through just about everything that was sustaining and supporting the big camellia above. No excavation or gopher mounds were observed. The area around the camellia was obscured by Algerian ivy. This all happened faster than the camellia could express symptoms associated with such damage.P90615+

3. ‘Kramer’s Supreme’. More specifically, “Award Winning – ‘Kramer’s Supreme’ – Camellia japonica – Trade Mark Registered”. Someone should have removed the label before it damaged the stem it was attached to. Actually, the long dead stem was stubbed just a few inches above the upper margin of this picture. It doesn’t matter now anyway.P90615++

4. This big mound of greenery is all a single big weed, perennial pea. I put it next to the wheel for comparison of size. It grew in a newly landscaped area where we did not expect such big weeds to grow so quickly. It did not seem to be as big as it is, so was easily ignored. Why didn’t gophers eat this instead of the now dead camellia above?!P90615+++

5. As you can almost see in the bad picture, perennial pea is not an unsightly weed. It also lays low and fits into the landscape in such a manner that it is easy to ignore while targeting more obtrusive weeds elsewhere. That is how the specimen in the picture above got so big. This one is not nearly as big, but overwhelmed a few smaller perennials.P90615++++

6. Perennial pea flowers are quite pretty. If possible, I like to let them bloom before pulling them up. Most look like these. Some bloom with fluffier double flowers. Some are lighter pink. A few are darker purplish. White is quite rare. As prolific as they are where they are not wanted, they are surprisingly unreliable from seed sown where actually desired.P90615+++++

Horridculture – Pesticides

P90612‘Cide’ as a suffix that designates something to be killed. ‘Insecticide’ kills insects. ‘Miticide’ kills mites. ‘Molluscicide’ kills molluscs such as snails and slugs. ‘Herbicide’ kills herbaceous plants, which are presumably weeds. These examples and other chemicals that kill things that are considered to be pests are collectively known as ‘pesticides’. Many are potentially useful in the garden, since that is where so many familiar pests are problematic.
Most modern pesticides are designed for physiological characteristics that are unique to the targeted pest. They therefore kill only very specific pests, but are generally harmless to other organisms. For example, horticultural oil, which is one of the simplest of all insecticides and miticides, kills insects and mites by obstructing the exoskeletal pores through which they respire. It is harmless to those of us who conduct respiration by means of lungs.
In fact, most (although not all) commonly available pesticides, if used properly, are relatively safe for those who are not the targeted pests. (Rodenticides that remain toxic to predators who eat afflicted rodents are some of the exceptions, but that is a topic for later.) That is why I have no compunction about using such pesticides. When necessary, I would use them on the farm, in the landscapes that I so often work in, or in the home garden.
However, such pesticides are almost never necessary. Seriously. I would not refrain from using them, but the need for such use almost never presents itself. Insecticides and, to a much lesser extent, miticides are sometimes applied on the farm (although I have not been there to apply any in a few years). I applied a minor fungicide for rust on English daisies in a landscape more than a year ago. Otherwise, pesticides are almost never necessary.
It is not that there are no pests. There most certainly are. Roses get aphid. Rhododendrons get thrip. Snapdragons get rust. We just deal with such pests without much pesticides.
There are so many alternative horticultural techniques to use instead. We prune roses so aggressively in winter that they regenerate faster in spring than the aphid can keep up with. We prune rhododendrons to eliminate much of the congested and sheltered inner growth where thrip tend to proliferate. Snapdragons are so susceptible to rust that we probably will not grow them again. Pests are not eradicated, but are reasonably controlled.
All too often, the problem with pests is not the pests at all, but improper horticulture.

Six on Saturday: Off Schedule

 

Every year is different. The weather is different. Bloom times are different. Growth rates are different.

1. Asiatic lily. This is one of five that were planted late enough last winter to be blooming right now, after others have finished. I would not have planted them so late, but that was when one of the neighbors shared them. They are a different color of the same sort of lily as the rose lily that was also blooming late last week.P90608

2. Peruvian lily. It seems to me that they were only beginning to bloom by this time last year. This year, they started blooming sparsely more than a month ago, and were blooming as profusely as they are now more than two weeks ago. There are pink and peach Peruvian lilies here too. I showed them off last years. (A peach flower can be seen out of focus at the bottom of the picture. A pink flower can be seen out of focus at the lower left corner of the previous picture #1 of Asiatic lily.P90608+

3. Rhododendron. Some bloom early and get battered by winter weather. Some bloom late and might get slightly roasted in the arid air of late spring. This one always bloom late like this, and has no problem with the weather. I do not know what cultivar it is. It certainly seems happy.P90608++

4. Dahlia. #1 Asiatic lily bloomed late. #2 Peruvian lily bloomed early. #3 rhododendron bloomed late. This dahlia did both. Dahlias typically only begin to bloom late in June. As you can see, this one already bloomed. I would not have shared this bad picture of a deteriorating early bloom, but was impressed that it bloomed at all. You see, it was dug and stored TWO winters ago, and then forgotten about. It somehow survived in storage through last year. I found it late last winter, and after determining that part of it was actually still viable, buried it right behind the lilies #1. It grew as if nothing had ever happened, and bloomed a year late and a month early. It has nice buds on in, so should resume bloom right on schedule, and continue to frost.P90608+++

5. Boston ivy. Four were planted over winter to climb a concrete retaining wall and a pair of concrete pillars supporting a bridge. The plan is to remove the Algerian ivy that hangs down over the retaining wall as it is replaced by the Boston ivy climbing up from below. I do not want to remove the Algerian ivy until necessary. I just want to keep it out of the way. I did not expect the Boston ivy to start growing like a weed so early. I cut the Algerian ivy farther to the left after getting this picture.P90608++++

6. Flowering cherry. Two plants; above were early. Two were late. One was both early and late. Well, this one won’t break the tie. These flowering cherries bloomed on time and are well foliated as they should be. In fact, they are better foliated and healthier than they have been in several years. They were so unhealthy last year that we had planned to cut them down and replace them by now. We just have not done so because we have not found replacements for them yet. Therefore, we are late; but it is not their fault. If it were at all possible, I would not remove them.P90608+++++

Horridculture – Fruity Fads

90417Pluots, plumcots, apriums and peacharines! Who comes up with this stuff?! Aren’t good old fashioned plums, apricots, peaches and nectarines good enough? Who decides that these weird hybrids are somehow better than their parents? Some of them are actually quite weird, or downright ugly. Several do not even look like they would taste good. It may be an acquired taste; but I have all the good taste that I need without acquiring any more.
Some old classic cultivars (cultivated varieties) of fruit were develop centuries ago. More have been evolving from those ancestors since then. Some were intentionally bred from parents with desirable qualities. Others just grew incidentally where their seed fell, and were found to be somehow better than their parents. Some were merely discovered as natural occurring mutants, and perpetuated for their superior qualities. It is a slow process.
So, putting two different kinds of fruits together, or finding an aberration of a single type of fruit, is nothing new. Tangelos were created by hybridizing Mandarin oranges with pomelos or grapefruits. Ever-bearing ‘Eureka’ lemon was perpetuated from a mutant of the seasonally bearing ‘Lisbon’ lemon. This is how cultivars evolve and develop. Generally, newer cultivars become popular because they are somehow superior to their ancestors.
Yes, somehow ‘superior’ to their ancestors. Who decided that a hideous hybrid of a plum and an apricot was somehow better than either a perfectly good plum or apricot? Furthermore, what evidence was there for such a weird claim? Even farthermore (if that is a word) how and why do so many people believe this evidence?
I was still growing citrus (trees not fruit) back in the early 1990s when the ‘Cara Cara’ pink orange was popularized. Yeah, a ‘pink’ ‘orange’. It is really just a pink mutant of the formerly more popular ‘Washington’ navel orange. We could not grow enough of it. It was just too popular. Some people really seem to believe that it is somehow better than ‘Washington’ and other navel oranges. I can’t argue. They certainly know what they like.
To me, it has a milder flavor than ‘Washington’. Yes, it tastes about as bland as it looks; pink.90320thumb

Six on Saturday: Oh, The Shame!

 

Not my shame of course; but that of the trees in the pictures below.

Do not try this at home. I only did it because I am a horticulturist and arborist; and I happen to be one of the last arborists in America who condones coppicing and pollarding, which are depicted here.

Coppicing is cutting trees or shrubbery down to the ground annually, or at least regularly every few years or so. Some coppiced trees form basal burls or lignotubers. Some just form thicket growth that replaces itself after getting coppiced back to the ground.

Pollarding is similar to coppicing, but rather than cutting all growth back to a stump or stumps at ground level, it involves pruning all growth back to the same distended knuckles at the ends of a few main limbs annually, or at least regularly every few years or so. It is done in such a manner that the pruning wounds are compartmentalized by the new growth of the following year. Knuckles can be elongated by leaving single short stubs.

There are a few reasons for coppicing and pollarding. Some subjects develop an abundance of appealingly lush foliage. Some develop an abundance of appealing or useful twiggy growth. Coppiced red twig dogwoods are much twiggier and more colorful while bare in winter. Pollarded or coppiced willows produce an abundance of canes for basketry. White mulberries are pollarded to provide an abundance of lush foliage to feed silkworms.

I coppiced a Eucalyptus globulus ‘Compacta’ and pollarded a Eucalyptus globulus for two main reasons. Both are such problematic trees that I do not want to plant either into the ground, so must keep them contained. Also, I want the remarkably aromatic juvenile foliage that develops in response to coppicing and pollarding.

1. Eucalyptus globulus ‘Compacta’ coppiced stump. It is not such a great example of a coppiced stump, since the tree did not grow enough two years ago to get coppiced last year. Consequently, the few main trunks that were just recently coppiced are already starting to form their own separate lignotubers on top of the original, which is now rotting below. Soon enough, they will fuse to form a single lignotuber, concealing the evidence.P90601

2. Eucalyptus globulus ‘Compacta’ before getting coppiced. It is quite small for a specimen that was not coppiced last year.P90601+

3. Eucalyptus globulus ‘Compacta’ after getting coppiced. Rhody is not impressed.P90601++

4. Eucalyptus cinerea in need of pollarding. This tree grew too big too fast to survive any longer in the relatively small #15 (15 gallon) can. Fortunately, in just a few days, it will instead get installed into a landscape where it can disperse roots and mature into a normal unpollarded tree. After a few years, it might get pollarded anyway, just to produce silvery juvenile foliage withing reach of the ground, but that is not a concern just yet.P90601+++

5. Eucalyptus globulus pollarded knuckle. This is only the second pollarding procedure for this subject. The first procedure involved lopping the lanky single trunk off right here where the knuckle is now. The multiple limbs that developed were just recently lopped off, leaving this distended knuckle to repeat the process, hopefully annually.P90601++++

6. Eucalyptus globulus pollarded trunk. This is why Eucalyptus globulus should not get pollarded! They look ridiculous if deprived of their naturally elegant form. They do not look much more dignified with multiple pollarded limbs. Oh, the shame!P90601+++++

Horridculture – Unpruned Fruit Trees

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 is that they were bred to produce an unnatural abundance of unnaturally large fruits that are too overwhelming to sustain as they ripen, and too heavy to support. The others are in a similar situation, but are somehow able to continue to produce and generally support their own weight as they get overgrown and congested. Roses deteriorate and succumb to disease as they get congested.
This is why annual winter pruning is so important. Such pruning concentrates resources into fewer but superior fruits, rather than too many inferior fruits. It also limits and contains (closer to the main trunk and limbs) the weight of the fruit, so that limbs are not so likely to break as fruit develops.
These wimpy stems hanging vertically from the weight of the maturing apricots might be able to support the weight of the fruit, but the excessive fruit will be of inferior quality.P90529+

Six on Saturday: Abbreviated Rose Parade

 

There are a few other roses that I could have gotten pictures of in order to submit a complete set of six, but I wanted to show off just these four that bloom in what is known as the ‘rose bed’. A fifth purple cultivar was not blooming when I got these pictures. What seems to be a sixth cultivar that I did not get a picture of is really suckers of ‘Doctor Huey’ understock that appeared far enough away from the original plant to not be a problem.

There are several rose shrubs and standards (trees) in the rose bed, but they are limited to these five and a half distinct and mostly unidentified cultivars. They are the most prominently located roses that I work with. The other roses are in other landscapes, or at the yard of the maintenance shops. Two of the larger groups of roses are uniform beds of carpet roses, which I am really none too keen on.

1. The few rose standards (trees) seem to be floribundas. This one looks familiar, but not familiar enough for me to guess the name of it.P90525

2. I would guess that this hybrid tea rose that grows in a shrub form is ‘Double Delight’. It does happen to be quite pleasantly fragrant.P90525+

3. This one seems to be a floribunda like the standards (trees) but grows in shrub form like #2 above. I do not believe it is notably fragrant.P90525++

4. I would guess that this one is the common floribunda ‘Iceberg’, growing as a standard. One is a double graft with a purple floribunda.P90525+++

5. Well, that was it. The fifth purple cultivar is not blooming, and ‘Doctor Huey’ bloomed only once for the year. This nearby yellow calla is irrelevant.P90525++++

6. This piece of dead madrone is just as irrelevant, but I though it was amusingly sculptural. I probably should have been more careful while cutting it apart.P90525+++++

Horridculture – High Fences

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 get it anyway because no one will build fences that will not provide it. In the 1950, fences were commonly four feet high, and not every backyard had them. By the 1970s, they were more commonly six feet high, and standard for almost every backyard. Now, fences are expected, and many are seven feet high or higher, with lattice on top!
Modern architecture and lifestyles are part of the justification for such tall fences. Low profile older homes on formerly suburban lots are commonly replaced with two or more larger homes on smaller subdivided city lots. They are much closer to each other than the older homes were, with only narrow spaces between upstairs windows, where even eight foot high fences will not provide privacy.
So, not only do much larger homes on much smaller parcels mean that there is much less space for gardening, but taller two story (or taller) homes with weirdly high fences mean that more of the very limited space available for gardening is shaded!

Six on Saturday: Willow

 

Rain is rare here so late in the season. It is also potentially damaging to some of the plants in the landscapes, and some of the latest of the spring flowers that are still blooming. Most of the deciduous plants are lush with new foliage on limber stems that are still adapting to the increased foliar weight. Foliage gets even heavier when it gets wet from rain. For the willows, the extra weight is enough to break limbs.

Willow limbs do not often break away cleanly. They instead split apart so that they fall slowly while still attached to the main tree. In the swampy conditions where they naturally grow, the broken but still attached limbs develop roots where they touch the ground, and then grow into new trees. Broken limbs are therefore not a problem for willows. Nonetheless, they are a problem in the landscapes.

1. This looks like mozzarella cheese being pulled apart. My great uncle used to bring some of the good Italian stuff when he came up from Long Beach for some of the Holidays. Oh my, how off topic!P90518

2. This is what it really was. Willow limbs are surprisingly weak this time of year. They don’t just break. They split apart. I should have gotten a picture of it before I cut it up.P90518+

3. It landed right across a walkway, where I could not put off breaking it apart and taking it away. With all the rain that caused it to break, the lawn was too swampy to walk around on.P90518++

4. It landed on this bench too, or at least the left half of it. With hundreds of acres of unused and unlandscaped forest out there, why must falling trees land in such inappropriate situations?P90518+++

5. All that mess was not even a full load. It just didn’t take up much space after it was all broken apart and loaded up. There was plenty of other willow to cut later in the day, and for the next few days.P90518++++

6. Willow! My niece named him. I knew better than to argue. I never liked the name though. I and almost everyone but my niece knew him as Bill, which is short for Willow. My friend Steven knew him as William.WILLOW

The Seventh On Saturday

P90511KThis is the one that got away; or actually, the one that was never caught. It bloomed after I got the pictures for the ‘Six on Saturday’ post for this morning. It could be the same unopened bud in picture #3 of the Six on Saturday post, as it is now blooming. If not the same bud, it is on the same plant, and now looks even more like the common ‘Simplicity’ rose. It is not my favorite, but I did not select it.
That is how the recovery nursery works. It is where we bring salvageable plants that need to be removed from their landscapes. Some were in the way of other projects. Some were not the right plants for their particular situations. Some were even donated by neighbors who thought we might be able to utilize them somewhere in the landscapes.
Some of plants brought in are not there long. They might get groomed and then moved directly to a more appropriate situation. That happens more during winter, when we dig up dormant plants and relocate them while the weather is still cool and rainy. We did this with a big overgrown forsythia that was dug and divided into five or so new plants before getting relocated into a new landscape. It helps is we can delay relocation until winter.
There are many potentially salvageable plants that must be moved at a particular time, even if it is not while they are dormant. They get groomed and canned (potted), and can take their time to recover before we put them back into the landscapes. Unfortunately, many do not recover adequately. Some end up staying too long because we can not find homes for them. After several years, the roses will finally be going to a new home soon.
