Six on Saturday: No Flowers – Again

These pictures seemed to be interesting when I took them. Only now I notice that there are no flowers here. Actually, there are not many flowers in the landscape where these pictures were taken anyway. Until last year, the facility associated with the landscape was used mostly during summer; so most flowers were selected to bloom during summer. Winter can be quite bland.

Also, for such a mild climate, winter can be surprisingly cool in some cooler exposed locales. Mild frost is normal. On rare occasion, if the weather is just so, puddles can get a thin layer of ice.

1. Lemon ripens this time of year. This pale greenish yellow color will become brighter yellow soon. I suspect that these are ‘Eureka’ lemon, but they crop very heavily in season, like ‘Lisbon’.

2. Flowering cherry will be spectacular in spring, but looks horrid now. This particular tree does not defoliate completely until just prior to bloom. It does this annually. This tree is ‘Kwanzan’.

3. Silver wattle is an an aggressively invasive exotic species locally. Fortunately, there is not much within the landscapes here. Now there is even less. I know it will regenerate from its roots.

4. Argyle apple is a silly name for this Eucalyptus cinerea. It grew from the lignotuber of an overgrown tree that was discarded from a retail nursery in Los Osos. The silver foliage is striking.

5. Lawson cypress also has strikingly silvery foliage. It is not as silvery as that of Argyle apple, but is slightly more bluish. The color of both species seems to be more striking through winter.

6. Ice is rare here, but possible. Of course, it is not as bad as it looks. It is very thin. Winter weather is innately mild here, which limits cultivation of apples and pears than require more chill.

Mugo Pine

Mugo pine is more shrubby than tree like.

Most shrubs and many perennials get larger than the diminutive mugo pine, Pinus mugo. The most common type grows very slowly as a dense and rounded mound only a few feet tall and maybe twice as wide. Only a very old specimen might reach an eave. The paired dark green needles are about one or two inches long. The symmetrical brown cones are a bit shorter. Mugo pine is also known as Swiss mountain pine and because of a misprint in the eighteenth century, mugho pine. Although native to mountains in Europe, mugo pine is most popular in Japanese gardens and for bonsai. Because it grows so slowly, it can be happy in planters and large pots. In large urns of regularly changed flowering annuals, it can be a nice permanent and evergreen centerpiece.

This Parade Needs Some Rain

Now, this is something you don’t see every day in a chaparral climate.

The lack or rain has really gotten serious! This winter so far has been the driest ever recorded. The past two winters had already been unusually dry. Even when the rain starts, it will be considerably behind schedule. Some seriously torrential rain will be needed to catch up.

As much as we like to think of gardening as something that brings us closer to nature, it demands unnatural volumes of water. Only established native plants or plants that are native to similar climates can survive with the limited moisture that they get from rain. This is why gardens get watered as much as they do.

Lawns of course require the most water because their shallow root systems require such frequent watering, and also because their vast foliar surface area loses so much moisture to evapotranspiration (evaporation from foliar surfaces). Lawns are the first and most prominent of landscape features to succumb to water restriction. Flowering annuals are the next to succumb, because they too want regular watering, especially while they are not getting any from rain.

Fortunately, lawns, annuals and other plants that want an abundance of moisture need less now because they are dormant or considerably less active through winter. Besides, evapotranspiration is inhibited by cooler temperatures, shorter day length, and most of the time, by higher humidity. It is nothing like the warm and arid (minimal humidity) weather during longer days of summer.

Many large and established shrubs and trees can survive quite easily with very minimal watering or even none at all. Established oleander, bottlebrush and juniper may not be as vibrant without watering, but should survive. If they notice a lack of water at all, it would not be until they start to grow again in spring. Mature trees take even longer to notice a problem.

Deciduous plants that are now bare really do not consume much moisture at all and really only need enough moisture in the ground to keep their roots from desiccating. This will only be a problem if the soil is very sandy and drains too efficiently to retain adequate moisture, or if freshly installed plants have not had enough time to adequately disperse their roots into the surrounding soil.

Automated irrigation systems should still be operated only minimally or not at all through winter. However, because of the unusually dry weather, they may need to be used a bit more than usual for this time of year to keep some things from getting too dry.

My Internship Was NOT In Australia

While recycling old articles from 2017, and now into 2018, I find that there are not enough to conform to the ‘Horridculture’ meme for Wednesday. The meme was invented a bit later. Well, if nothing else, this old article is amusing.

tonytomeo's avatarTony Tomeo

P80106Australia, New Zealand and South Africa were the hip and trendy places to do internships in horticulture back in the late 1980s. Everyone who was anyone was doing it; which is sort of why I was not that interested in doing what everyone else was doing already, even if I could have afforded to go to any of those exotic places. I did my internship in Saratoga.

All I knew about Australia was Olivia Newton John, Helen Reddy, eucalyptus trees, and that it is the place where summer goes when it leaves here.

Since writing online and learning a bit more about horticulture in Australia, I incidentally found that Australia is stranger than I would have imagined.

There are no Pontiacs in Australia! Seriously! When someone asked about what to do with a surplus of peaches that were too overripe and squishy to can, I suggested that they get thrown…

Apricot

Apricot trees get planted in winter.

Apricot has major history in California. For a very long time, it was the main agricultural commodity is several regions, particularly the Santa Clara Valley. It remains a significant commodity within portions of the San Joaquin Valley. Urban sprawl replaced orchards in other regions. However, apricot trees now inhabit some urban gardens. The climate here is as ideal for them as it ever was.

Garden variety apricot trees are not quite like orchard trees. Dwarfing rootstock keeps them somewhat more compact. They might otherwise grow taller that twenty feet. Production is best during the first three decades or so, before they begin to slowly deteriorate. Orchard trees are already due for replacement by then. Many more cultivars are practical for home gardens than for orchards.

Apricot trees, which are mostly of the species Prunus armeniaca, are certainly not ‘low maintenance’. They require specialized pruning annually, while dormant for winter. Otherwise, they produce more fruit than they can support. New trees are unlikely to produce any fruit during their first season. The deciduous foliage falls neatly in autumn. White or slightly blushed spring bloom is striking.

Bare Root Stock Makes Sense

Snowball bush is available bare root.

Winter has potential to be a slow season for gardening. Simple gardens may not require much dormant pruning. Established gardens may not require much planting. Where winters are cold and perhaps snowy, no one wants to go outside anyway. Those who go out may not be able to accomplish much. Nonetheless, winter is the season for planting bare root stock, which is now available.

Bare root stock starts to move into nurseries before the last Christmas trees move out. Growers start to dig and package it as it goes dormant for winter. They separate it completely from the soil it grew in, leaving the roots bare. Some bare root stock is available with bags of damp sawdust protecting its roots. Most goes into bins of damp sand to protect the roots while at retail nurseries.

Unlike canned (potted) nursery stock, bare root stock must get into the garden as soon as possible. It will not survive long if it gets warm enough to start growing prior to planting. Nor will it survive if roots desiccate. Unbagged bare root stock can soak in water for a limited time. For planting, roots should flare outwardly. Soil amendment should be limited. Graft unions must be above grade.

Bare root stock is lightweight, compact, and easy to handle in bulk. Therefore, it is less expensive than canned stock. It is also easier to get home and plant. Because so many individual plants fit into limited space, many more cultivars are available from nurseries. Even more are available by mail order. Bare root stock disperses roots and gets growing more efficiently than canned stock.

Deciduous fruit trees might be the most popular bare root stock. This includes apple, pear, persimmon, fig, mulberry, walnut, pomegranate and the stone fruits. (Apricot, cherry, peach, plum, prune and nectarine are stone fruits.) Grape, currant, gooseberry, blueberry, blackberry and raspberry bare root stock are also available. So are perennial rhubarb, asparagus, artichoke and strawberry.

Ornamental bare root stock includes rose, snowball bush, forsythia, wisteria, flowering crabapple, poplar and many more.

The Molting Of The Chrysler

The weather here can be rather boring. Contrary to popular belief, it can get slightly frosty, and sometimes moisture falls from the sky. This old article can explain a bit of that.

tonytomeo's avatarTony Tomeo

P80108+The old Chrysler looks different this time of year. Like dogs, cats, horses and deciduous plants, it adapted to the weather.

That tan canvas structure above the cab is known as a ‘roof’. It was there all along, but folded up behind the back seat. It was merely unfolded over the top of the cab. The ‘roof’ comes in handy this time of year, not only for keeping warmth within the cab, but also for keeping things out of the cab. Allow me to elaborate.

You may nave noticed that the Chrysler is wet. This is a direct result of mysterious droplets of moisture that fall from the sky. We discussed them earlier. They are known ‘rain’, and are falling from the sky presently. The ‘roof’ keeps the ‘rain’ out of the cab. Otherwise, the cab and everything in it would be as wet as the ‘roof’ is now.

Well, Well, Well!

Apologies! I neglected to post anything at noon today. I still lack time to write, so will share this old article from a few years ago.

tonytomeo's avatarTony Tomeo

P80106+Right next door to my downtown planter box, ( https://tonytomeo.wordpress.com/2017/11/04/my-tiny-downtown-garden/ ) just to the east on Nicholson Avenue, there is a tree well for a small London plane street tree that has not grown much in the past few years since it was installed. The poor tree is in a difficult situation. It probably does not mind getting bumped with car doors every once in a while, but bicycles getting chained to it have been abrasive to the bark of the main trunk. The location next to a Mike’s Bikes does not help. The staff at Mike’s Bikes has had limited success with promoting the use of a nearby bicycle rack instead, by displaying their own bicycles next to the tree.

The tree well collects a bit of trash that gets blown about by the wind. Weeds are sometimes able to grow up through the mulch of detritus. No one…

Six on Saturday: HAPPY NEW YEAR!

2021 was already a popular year before it got started. Many wanted 2020 to end, as if all the unpleasantries of last year would end with it. To me, the first day of this year seemed to be just like any of the few last days of last year. That is not necessarily bad. There was quite a bit of good last year, even with all of the unpleasantries. Many of us see examples of it in our gardens.

Well, these pictures happen to be from yesterday, the first day of January and 2021.

1. Eucalyptus sideroxylon, red ironbark, is the first tree I planted in 2021, on New Year’s Day. It died back last spring, and regenerated with shrubby growth, so got pruned to a single trunk.

2. It should be glad to be out of its can, and into a new home. It originated as a root sucker of a tree that had been cut down. It came up with roots when I pulled it, so could not be discarded.

3. Agave attenuata, foxtail agave, got run over on Pacific Avenue in Santa Cruz. It was not crossing the road, but just minding its own business in a median. I could not leave it there like that.

4. It should be happy here. Adventitious roots are already developing on the trunk. A small section of the base of the trunk was cut off and canned so that new pups could mature separately.

5. Hedychium gardnerianum, Kahili ginger, originated from a neglected landscape near where the red ironbark eucalyptus originated from. Foliage from last year will shrivel through winter.

6. Quercus lobata, valley oak, is the Memorial Tree, and is the first tree that I pruned in 2021. It is developing well. I will return to stabilize the lodgepole stake, and adjust the binding stake.

Common or Soft Rush

Physiologically, common rush is more interesting than it looks.

There was nothing common or soft about Rush, the innovative hard rock band of the seventies and eighties. Juncus effusus is only known as soft rush because the spiky and sharply pointed ‘foliage’ appears to be stiff, but is actually quite soft. It is common because in has such a vast natural range, including North America, Europe, Asia, Africa and Australia. It does not like hard rock, but instead prefers rich and moist soil, and will even be happy in soil that is too damp for other plants. Common rush tolerates a bit of shade but prefers good exposure. Because winters are too mild to freeze it back to the ground naturally, overgrown or discolored common rush can be cut down and then left to regenerate as winter ends.

The distinctive ‘foliage’ is not actually foliage. The minute leaves are unimpressive brown scales that do not do much at the base of each of the many upright green stems that function like foliage. The top six inches or so of each of these spike like stems is actually a bract that extends above the dangling but uninteresting tan or dingy yellow flowers that hang to the side. Collectively, the stems and bracts form distinctively sculptural clumps that radiate upward and outward. Healthy clumps are not much more than three feet high and wide.
