Escargots

French hors d’oeuvres are somehow among the most bothersome of garden pests within California. They are voracious. They are very prolific. They are sneaky. They are more resilient to attempts to limit their damage than they had been in the past. Furthermore, attempts to limit their damage are less effective than they had been in the past.

Molluscicides, which are the pesticides that are formulated to be toxic to molluscs such as snails, are not nearly as toxic as they had formerly been. Years ago, they were so toxic that they had potential to be dangerous to cats, dogs, wildlife or children. They are safer for everyone now, including the molluscs that they should be toxic for. Some snails succumb after consuming such molluscicides, but some survive.

The progeny of snails who survive consumption of molluscicide are genetically more likely to also survive consumption of the same molluscicide than snails who did not survive to proliferate. Those who do not inherit such genetic resilience do not survive to proliferate. Consequently, each subsequent generation is more resistant to the particular molluscicide than its preceding generation. Although a different molluscicide would be more effective temporarily, a few snails survive it also, to proliferate and repeat the process. It is how they ‘develop resistance’.

Besides, many garden enthusiasts are hesitant to apply molluscicides because of how toxic such pesticides had been in the past, and how, regardless of how much safer they now are, they must still be toxic to some degree in order to be effective.

Lushly landscaped and generously irrigated home gardens are ideal habitats for snails. Vegetation within such landscapes is damp and sheltered, and provides an abundance of sustenance. Skunks, foxes, ducks and other wildlife that eat snails generally avoid or lack access to many urban home gardens. Opossums and raccoons are either uncommon, or more interested in eating fruits, vegetables, trash or dog and cat food.

Litter Problem

It will not DIE!

We have a litter problem. At least three species of Agave continually have litters of pups. We give almost all of the pups away to friends and neighbors, but more constantly appear. I suppose that we could dispose of some, but that is not easy for those of us who enjoy growing vegetation instead of destroying it.

Pups of one Agave continue to appear where the original was relocated from several years ago. Although I do not know what species it is, it is likely my favorite of the three. However, we can not accommodate all these pups! The original is happy with its new situation, but is beginning to generate a few more pups there as well.

Pups of Agave americana, century plant, got canned because we thought that we could eventually find homes for them. Now, and for the past few years, these maturing pups are producing more pups, some of which are emerging from the drainage holes of their cans! The original is happy to be a neighbor of the unidentified Agave, but could generate more pups at any time.

Agave ovatifolia, whale tongue agave, was purchased by the other horticulturist for a specific situation. It was a striking specimen that was worth what was spent on it. However, it began to generate pups almost immediately after installation, and then suddenly and unexpectedly bolted and bloomed. It was disappointing for such an expensive specimen of a monocarpic species. We removed it after bloom, with the intention of replacing it with one of its several maturing pups. Of course, I could not simply dispose of its carcass. I canned it like a dormant perennial, just in case it did something. Well, now it is doing something! It is bolting and blooming from the grave! I expect more pups soon. We really should get all the Agave spayed!

Agave really should be spayed!

Six on Saturday: Hello Yellow

White is my favorite color. I sometimes post six pictures of exclusively white flowers for Six on Saturday. Also, I posted six pictures of exclusively red flowers merely to show that I could. I might have tried other colors as well. I do not remember trying yellow though. California bay gave me the idea, although its bloom is rather unimpressive. Silver wattle is much more colorful. So is daffodil. Dandelion is merely a weed; but technically, silver wattle is also. Ultimately, I got four pictures of yellow flowers, a picture of an aberrative beet, and a picture of someone who might qualify as golden retriever light gold, which at least sounds yellow. He can not see most colors anyway.

1. Acacia dealbata, silver wattle is an aggressively naturalized exotic species. It certainly is pretty though. It typically blooms earlier, and maybe by New Year’s Day farther south.

2. Umbellularia californica, California bay does not bloom as prettily. Its flowers are too tiny, too sporadic and too high in its canopy to be prominent, but it blooms nonetheless.

3. Taraxacum officinale, dandelion, like silver wattle, is also an aggressively naturalized exotic species. It infests most lawns, and blooms to toss its seed whenever it wants to.

4. Narcissus pseudonarcissus, daffodil continues to bloom. Several are still budded. If it were not so variable with its bloom schedule from year to year, I would say that it is late.

5. Beta vulgaris, beet should be red, not yellow. ‘Detroit Dark Red’ is best! This seems to taste about the same, but looks like a sick carrot! I loathe carrots! Why do this to a beet?

6. Rhody remains unimpressed. He is no more interested in beets than carrots. He could be more concerned about the first of a few storms that should arrive in only a few hours.

Horridculture – Salvage

A hedge of a dozen like this came from one branched stump.

This is an old and redundant topic. I should know better. Some vegetation is not worthy of salvage. Even that which is worthy can become excessive if too much is salvaged. The problem is that I find it very difficult to discard vegetation that I can relocate to another landscape, or grow in the recovery nursery whether or not we have use for it.

A few stumps of shrubbery needed to be removed from a small landscape of one of the buildings at work. With one exception, the shrubbery was common Photinia X fraseri, which had been cut down some time ago, and had not grown back much. The one exception was a common Escallonia rubra, which had been cut down even earlier, so had grown back about five feet tall, with a few distinct trunks.

I had no problem discarding the Photinia X fraseri. The stumps came up with mostly severed large roots, and very minimal fibrous roots that they needed to survive. If I really want to grow more, it would be more practical to grow it from cuttings. I am none too keen on the species anyway.

The Escallonia rubra was not so simple. Although I was determined to discard it all, and I am no more fond of the species than I am of Photinia X fraseri, it came out with more than enough fibrous roots to survive relocation. What is worse is that the several trunks were easily divided into several individual well rooted specimens, with several more layered stems attached to them. I assembled an even dozen well rooted specimens as a hedge outside a fence of our maintenance shops, and nine smaller rooted cutting to alternate between cypress trees outside another similar fence. Although pleased with the results, I should have discarded them.

This is one of the smaller well rooted specimens, although the layered stems are smaller.

Mojave

Joshua trees seem to be scarce near Joshua Tree.

About a quarter of California is desert. Most of that desert is part of the Mojave Desert. Much of it is very sparsely populated. All of it is fascinating to those who appreciate it.

Not many people live in the desert because the climate is so harsh, and because there is not much reason for many people to be there. Not far north of Los Angeles, which is the second most populous city in America, is one of the most sparsely populated regions of America within the Mojave Desert. It is unpleasantly hot and dry there all summer. It is certainly not the sort of place that should be appealing to horticulturists, although it is.

Brent sent me this picture from a place where he vacations near Joshua Tree. If there are Joshua trees near Joshua Tree, they are not visible within this picture. Actually, no trees are visible within this region where shade must be very important. The vegetation that is visible does not seem to be substantial. Vegetation is completely lacking within the fenced area. That small pile of firewood must have been brought from somewhere else. (Although nights are pleasant or warm between hot days, they can get very cold between cool days of winter.) I do not know what that building is. Without substantial vegetation, neighboring residences are visible in the distance.

Part of the allure of deserts for horticulturists is the very distinctive vegetation that lives only there. Part of the allure is the minimalism of such vegetation. Although many species live there, they are not very distinctive. Many resemble each other. In other words, much of the vegetation of the desert is easy to ignore. It is less distracting than that of other ecosystems that are more popular with those who are not horticulturists.

Ginger Ail

White butterfly ginger is still green.

At least seven gingers live here. Five are ornamental. Two are culinary. None have yet died back as they should for winter.

Now that it is time to divide them, I do not know what to do with their intact foliage. For this white butterfly ginger from Forest Garden, I divided the rhizomes and installed them into the landscape with their healthy foliage still attached. I do not want to cut it back until it succumbs to frost. I suppose that it can remain as long as it is healthy. It is likely promoting healthier secondary growth. Because none of the gingers are crowded yet, it should not be difficult to selectively groom out older growth as new growth develops. I doubt that older foliage absolutely must be pruned away during winter. If it were that important, the rhizomes would shed it naturally, with or without frost.

This is a mild climate, with very mild frost; but gingers should still die back for winter regardless. Cannas certainly do, even without significant frost. Even some of the banana trees were somewhat unhappy about the chill.

Actually, the banana trees seem to be bothered more by chill than the gingers. Is this normal? Angel’s trumpet, cup of gold vine and blue ginger (which is not related to ginger) also expressed more displeasure than the gingers.

I really should have sheltered some of these species better. Actually, I probably should not be growing so many species that are so sensitive to chill and frost. I will be going to Southern California again in about April, so could bring back even more tropical species. It is a bad habit.

Technically, the average last frost date is about a month and a half from now. Technically, a bit of frost is possible even after that.

Six on Saturday: Palm Springs

Palms spring up anywhere they want to. Only the fourth and sixth of my Six on Saturday are not feral. Incidentally, the last three are not my pictures; and Brent sent the last two. His curbside Mexican fan palm is at least one of the parents of my pair of seedlings here.

1. Washingtonia robusta, Mexican fan palm, which I wrote about earlier, was too pretty to stay in the recovery nursery where no one can see it. We put it here temporarily, until a pup from the Agave ovatifolia, whale’s tongue agave that bloomed and died here, gets large enough to replace it. It is canned within the big pot for ‘efficient’ removal, but is so heavy that I have no idea of how to get the can out of its pot. It will be a bit heavier later.

2. Wicked spines on its petioles contribute to the difficulty of relocating this heavy palm.

3. Trachycarpus fortunei, windmill palm is also too pretty to stay unseen in the nursery. It will also get groomed and relocated temporarily to a landscape next week. This young palm grew in the garden of the mother of childhood friends, so I am very protective of it.

4. Palms and redwoods do not mix well. A colleague wants this windmill palm gone. It is about twenty four feet tall. That ladder is eight feet tall. It will be difficult to relocate, but I do not want it cut down and killed. Like the others, I have no idea of what to do with it.

5. Brent’s curbside Mexican fan palm looks embarrassed with its silly uplighting. That is the moon above. This palm, which is a Memorial Tree for Brent’s brother, was about ten feet tall when relocated here because it grew under electrical cables several blocks away.

6. Bedford Drive, nearer to the original location of Brent’s curbside Mexican fan palm, is flanked by very old and alternating Mexican fan palms and Phoenix canariensis, Canary Island date palms. They were grandly uniform until the Canary Island date palms began to succumb to pink rot during the 1980s. The Beverly Hillbillies started their shows with a scene of their arrival in town on a similarly flanked street three blocks to the northeast.

Horridculture – Weather

So close to ripening!

The weather here made national news on Sunday night. It was apparently quite a storm, with unusually windy wind. A few trees fell in the neighborhood. The roads were messy with debris. The electricity at home was disrupted. Otherwise, to me, it did not seem like a particularly bad storm. After all, this is winter.

HOWEVER, on Saturday, even before the worst of the weather on Sunday, the wind knocked over my small ‘Ponderosa’ lemon, only a few hours after I posted a picture of one of its two developing fruit. It is a dinky tree in a #1 can, but its lemons are disproportionately large. As I mentioned on Saturday, I should have removed the lemons to divert resources to vegetative growth, but wanted to see if they would develop and ripen. The weather did it for me.

Now I am annoyed. I do not like to be one who complains about the weather. There is not much to complain about in that regard here. This is a pleasantly mild climate that lacks the sort of severe weather that other climates must contend with. The gust that blew over the small lemon tree was not nearly as strong as those that blew over trees within the surrounding forests and neighborhoods. I am just annoyed that after letting the lemons grow as much as they did, their effort will now be wasted.

The two lemons did not develop as they should have, but are still bigger than average ‘Eureka’ or ‘Lisbon’ lemons. I put them aside to ripen if they can. I doubt that they will. I can prune the small tree to remove the stems that had previously supported the two lemons, and make cuttings of them, to grow more small trees. Actually, I should have done this anyway.

1986

Since 1986 (or so)

This is no ordinary daffodil. I realize that it looks just like the daffodils that I posted a picture of two Saturdays ago, and it could actually be the same variety, but it is quite distinct. I acquired this particular daffodil in about summer of 1986. It could have been a year or two earlier or later, and might not have been summer. The foliage was not completely shriveled as it should have been during summer, but it lasts longer in the coastal climate that I took it from. I really do not remember when I acquired it, but I know that it was a long time ago, about the summer of 1986.

Although we have not been acquainted for as long as I have been acquainted with my paternal paternal great grandfather’s rhubarb and my maternal maternal great grandmother’s Dalmatian iris, both of which I acquired prior to kindergarten, we have significant mutual history.

I ‘borrowed’ several large clumps of bulbs from an abandoned flower field to the east of my Pa’s home in Montara. The clumps were very overgrown and very crowded, but still in their original rows, as they had been arranged for cut flower production many years prior. Shortly afterward, all of the other bulbs were somehow and seemingly pointlessly removed from the field by an excavator. A monster home was built on the highest part of the field, with a view of the field, which remained completely uncultivated afterward. No one knows how or why all the daffodil bulbs were removed so completely, but none were ever seen again. The naturalized field of daffodils seemed like it would have been an attribute to the home.

Over many years, the bulbs grew at most of the homes that I lived in, until the last few years, after I left the last of them at a former home in town. Then, after bringing a few roses here from my old rose garden at a previous home, I noticed that a few bulbs came with them. I thought that they were fancier daffodils, but now that this one bloomed, it is obvious that they are the familiar daffodils from Montara.

Ponderosa

‘Ponderosa’ for the Ponderosa

Citrus ripen through winter. This ‘Ponderosa’ lemon is taking its time, probably because it is still growing. Individual ‘Ponderosa’ lemons commonly weigh two pounds, and can potentially get a bit heavier than five pounds. That is heavier than some of Rhody’s chihuahua friends. I doubt that this particular lemon will get much larger than it is now, but it is already bigger than an average ‘Eureka’ lemon. It is about as big as a baseball.

The problem with this fruit is that it is on a tiny lemon tree in a #1 can. It is one of two fruits. I should not have allowed them to develop as much as they have. I should have removed them when they first appeared in order to divert resources into vegetative growth, rather than fruit development. Now that they grew this much, I sort of want them to finish ripening. It would be a waste to remove them now. After they ripen, I can prune their stems from the tiny tree, and process them as cuttings to grow more new trees.

I would like to install this little ‘Ponderosa’ lemon tree into a landscape at Ponderosa Lodge. Not only is its name appropriate, but the weirdly huge fruit might be interesting to the children who come to ‘Outdoor Science’ school there. Contrary to the huge size of its fruits, ‘Ponderosa’ lemon trees do not grow very large or very fast. However, a mature ‘Eureka’ lemon already inhabits the garden there, and we recently installed a ‘Bearss’ lime. Another lemon tree would redundant. We would prefer to grow a more edible citrus within the limited space that is available, such as a sweet orange, Mandarin orange or kumquat. For now, we will just enjoy this tiny lemon tree with its huge lemons right here.
