Peach

70726thumbJust like roses and camellias, the innocent peach, Prunus persica, has been developed into too many distinct cultivars to write about in just a few brief paragraphs. It had been in cultivation for thousands of years before arriving in North America. Peach is a classic summer fruit, but trees should be planted while dormant, preferably as bare root stock, about now, in the middle of winter.

Peaches certainly do not grow everywhere in North America. They need just enough chill to be reminded that it is winter; but too much chill too late in the season will ruin bloom. Too much late rain will rot developing fruit. Peaches are therefore right at home in chaparral climates of California, where freestone cultivars are grown for fresh fruit, and clingstone cultivars are grown for canning.

Healthy peach trees can get up to second story eaves, but if properly pruned, should be only half as tall. They should not get too wide either, since the weight of fruit can break limbs. Aggressive winter pruning keeps trees vigorous and resistant to disease. Orchard trees last less than twenty years, although home garden trees are often kept longer. Nectarines are just fuzzless peaches.

Bare Root Season Is Now

80124thumbAutumn really is the season for planting. That is the general rule. One generalization about general rules is that they generally do not apply to all of the specifics. In other words, there are likely certain exceptions. In this case, there are some types of plants that should not be planted in autumn. The next best season for planting is probably winter, which happens to be ‘bare root season’.

Just before the last of the Christmas trees were being sold, and relinquishing their space in nurseries, bare root stock started moving in. Some bare root stock is prepackaged with its otherwise bare roots in bags of moist sawdust. Nurseries that provide large volumes are likely to heel in unpackaged bare root stock into bins of moist sand, from which it gets pulled and wrapped as sold.

As the term ‘bare root’ implies, bare root stock was dug as early as the onset of dormancy in late autumn, and deprived of the soil that it grew in. Because it is dormant, and the weather is cool and damp, it does not mind much, if it even knows at all. As it emerges from dormancy next spring, it resumes growth, and disperses roots into the new soil that it got planted into while dormant.

Bare root stock is significantly less expensive than canned (potted) stock because it lightweight and does not take up much space in the nursery. It is also more efficient, since it only stops briefly in retail nurseries, on its way from growers to its final home destinations. New plants start dispersing roots right away, instead taking time and effort to recover from earlier confinement of roots.

Deciduous fruit trees and roses are the most familiar of bare root stock. The bare root fruit trees include the stone fruits of the genus Prunus, such as apricot, cherry, plum, prune, peach, nectarine and almond, as well as pomme fruits, such as apple, pear and quince. Figs, pomegranates, persimmons, walnuts, mulberries, grapevines, currants, gooseberries, blueberries, cane berries, strawberries, rhubarb, asparagus and a miscellany of deciduous blooming but fruitless plants are also available.

Unplanned Green Roof

p90106The last green roof that I wrote about was planned, although not in a typical manner. https://tonytomeo.com/2017/11/25/green-roof/ It is still my favorite green roof. Otherwise, I am none too keen on the fad. Very few buildings benefit from green roofs, and green roofs really do take more work than conventional landscapes in the ground.

The sort of green roof pictured here was most certainly not planned. It could have been the result of a an uncleaned gutter. All sorts of weeds can grow in the damp debris that can wash off of roofs, particularly in damp and foggy coastal climates where moisture so often drips from the edges of roofs. This gutter is just a short distance from the beach in Santa Cruz. The willows in the San Lorenzo River are next door.

Knowing what I know about this particular type of willow, I would guess that the cleanliness of the gutter, or lack thereof, was not really the problem. These aggressive willows can germinate in the slightest bit of debris, even under a single leaf that did not get rinsed or blown away fast enough. Once germinated, their finely textured roots are experts at clinging to anything that might otherwise get rinsed away. If there is not enough debris and dirt for them to grow in, they simply collect their own. Now that it has started the process, it will continue to collect debris and expand its root system until it gets removed or ruins the gutter. It seems to have already collected enough debris to share with a few grassy weeds nearby. It is mostly dormant now, and might have defoliated in the rain since this pictures was taken a few days ago. However, if it stays, it will resume aggressive growth as winter ends.

Addendum

p90105kThere is much more to the landscapes at work that I wrote about earlier this morning at https://tonytomeo.com/2019/01/05/six-on-saturday-cabin-fever/ . Otherwise, my job would be quite boring.

I do not climb big trees; so any work that the redwoods need must be done by someone else. The big redwoods, as well as the ponderosa pines, Douglas firs and various oaks, are of course the most prominent and memorable features of the landscapes. There are also a few other exotic trees that were added to the landscapes years ago. My primary work with those that have grown beyond my reach is identifying problems for other arborists to correct or remove.

However, there is plenty at ground level to keep us very busy.

Our landscapes are simple and somewhat unrefined. They take as much work as they do because they are so big and dispersed over a large area. There seems to be only a few small beds of flowering annuals, but collectively, these flowering annuals cover quite a significant area. There are likewise only a few roses here and there, but they add up to quite a big collection.

This firethorn lives in one of the landscapes that we maintain that is more than a mile away from the pictures that I posted earlier this morning. It is an area forested with big ponderosa pines and chaparral plants. Unlike the deep and dark redwood forest, this area is warm and sufficiently well exposed for all these bright red berries to develop. It is a completely different climate zone, soil type, and landscape style. Because it is within the context of a much larger and rustic landscape, I do not notice it like I should. Now that it got my attention, I got its picture before the birds take all the berries.

Six on Saturday: Cabin Fever

 

Seriously! The flu!, or something like it. I was totally sick for days, with an awful fever. As if that were not bad enough, it happened while I was supposed to be relaxing and on vacation!

Neither was planned. Getting sick never is. The vacation was a total surprise too; a Christmas gift from one of the guys at work! It was totally rad, even if I was sick for it.

You see, we work at one of the most excellent places in the entire universe, where people come from all over for restorative retreats. That by itself is totally rad. What is radder is that we can rent unused rooms or cabins for out-of-town guests or for ourselves if we like. It is very affordable, and like vacationing at work. That may not seem like much fun for those who do not enjoy their work like we do, but like I said, this is one of the most excellent places to work in the entire universe.

So, my colleague got me nine nights in what is classified as an ‘economy’ cabin, but by my standards was very luxurious. I had stayed in a smaller newly remodeled cabin for two nights, and a hotel like room for a night, but had done nothing like this; nine nights in secluded luxury! If one must get sick, this is the way to do it!

Anyway, this is where my six pictures for this week came from.

1. This is the upward view from the front door. The black margin at the top of the picture is the edge of the eave. The trees to the left are canyon live oaks and a tan oak. The trees to the right are towering coastal redwoods.p90105

2. This is the same spot. Instead of looking straight up, this is looking outward from the front door. There is no refined landscaping here; only the native trees with the exotic English ivy that is cascading slightly over the old stone wall.p90105+

3. These towering coastal redwoods are outside a bedroom window.p90105++

4. These towering and somewhat darker coastal redwoods are outside the bathroom window.p90105+++

5. The artwork on the interior walls are mostly pictures of the local flora and wildlife. Most are rather artistic. Some are pictures of common but exotic flora that, although probably appealing to those who do not recognize them, are not the sort of subject matter that I would have selected. For example, one of the big framed photographs in the bedroom is a closeup of the summery foliage of London planetree, Platanus X acerifolia. Ick! I took this picture of three pictures that I found to be amusing. On the left, we have some interesting lichens and a bit of moss on what seems to be an apple tree. Okay. In the middle, we have foliage of California bay tree, Umbellularia californica. Odd, but again . . . okay. On the right, we have maces from the exotic sweetgum, Liquidambar styraciflua. Now, I would say that is weird, but it really is a cool picture!p90105++++

6. Rhody was not supposed to be on the bed.p90105+++++

‘Red Star’ Atlantic Whitecedar

60106Is it red or white? Actually, it is neither. ‘Whitecedar’ is the common name for Chamaecyparis thyoides, which is a formidable coastal conifer from Maine to Mississippi. ‘Red Star’ is a much smaller garden variety. Its finely textured foliage is bluish green when it first emerges in spring, and can turn slightly purplish or bronzed gray if it gets cold enough in winter, but never turns red.

In more humid climates, ‘Red Star’ Atlantic whitecedar can eventually reach second story eaves, and can get half as broad. It rarely gets half as large locally, and can take quite a few years to do so. The slightly aromatic evergreen growth is densely conical, almost like a lumpy dwarf Alberta Spruce with an upwardly rounded underside. It can be a bit more sculptural if partially shaded.

Even without pruning, ‘Red Star’ Atlantic whitecedar is symmetrical enough for formal landscapes. Alternatively, it can add a bit of formality to relaxed landscapes. Although it is slow to provide privacy, it works nicely as an unshorn hedge. If somewhat crowded in a row, it grows taller faster. Shorn hedges lack natural form, but can recover their natural texture between shearing.

Fireplaces Are A Rare Luxury

51028thumbThere are fewer fireplaces after every significant earthquake. Removal of a damaged chimney is probably more practical than repair, particularly if the fireplace does not get much use anyway. Wood stoves sometimes get removed simply because they are in the way. Modern building codes forbid their return once they are gone, and also forbid them in new construction.

The few surviving fireplaces and wood stoves do not get used as regularly as they used to. It seems that no one is around the home long enough to tend to a fire. Orchards that provided so much affordable firewood as they were being removed for urban development are gone now. The outskirts of town, where trees and woodlots might be found, are now more than a short drive away.

Firewood can still be purchased from tree service businesses that must dispose of the wood that their work generates. Because such firewood is a byproduct of urban forestry, it is an unpredictable mix of all sorts of urban trees, and must be procured early in the year to be seasoned by autumn and winter. It is now much too late to purchase green firewood for this winter.

Almost all types of urban firewood are comparable to more traditional types. A few types deposit more residue in chimneys, so that chimneys need to be cleaned more frequently. Firewood from woodlots can be surprisingly more expensive; but it burns cleaner, and is already seasoned. Many woodlots would be pleased to deliver firewood that is ready to burn now.

Firewood is perishable, so only slightly more than enough for one year should be procured annually. Any leftovers can rot if left out in the weather too long. Firewood last longer in a shed or garage, but takes up too much space, and can be attractive to rodents.

Synthetic logs from the supermarket happen to be more efficient than real wood, and do not need to be seasoned. A single log burns longer and cleaner than a few real logs, and produces as much heat. However, they are individually very expensive, and are just not the same as real firewood.

Horridculture – Clearance

P90102Many arborists mark certain lengths on their pole saws and pole pruners. When stood upright, these marks designate the standard heights for minimal clearance pruning. Not so many need to mark the height of minimal clearance for walkways, since they will prune away anything that is within reasonable reach with hand tools from the ground. The minimal clearance above parking spaces is not so easy to guess at, so is more likely to be marked on poles. So is the minimal clearance over roadways, where the lowest limbs must be high enough to be out of the way of campers and freight trucks.
Clearance to the sides is determined by the location of the curb, but even that might need to be modified at sharp turns, or where the roadway slopes significantly away from the center. Clearance must similarly be a bit higher over dips in a roadway, where the height of long freight trailers would be affected by the elevation of the wheels in front and back (outside of the dips). Clearance around street lighting, roofs, utilities and such is determined by the object that requires clearance, so no marks must be made on the poles for such work. (Clearance pruning of high voltage cables is only performed by those who are qualified to do so.)
Clearance pruning is serious business for arborists. They do not want their trees to hurt anyone, or to damage vehicles. Nor do they want their trees to be damaged by vehicles. Obtrusive limbs can be torn away by freight trucks. Even if not torn away, limbs that are regularly battered by freighter trucks are rather unsightly.
As someone who used to drive the delivery truck, I can tell you that clearance pruning is also important for some of us who use the roadways.
These three young Italian stone pines are healthy specimens that are probably well structured inside all of the outer foliage. It is hard to say, since I can not see inside through all the disfigured lower foliage that has been continually battered by truck traffic. They probably only need to be pruned for clearance above and away from the traffic. If pruned to establish a minimal ceiling just two feet or so above the obvious damage, and to remove all the lower growth to the side, they would be excellent street trees for many years. They will eventually need to be pruned again, as maturing branches sag from their own weight, but that is to be expected. The main trunks and bulky limbs within would probably be quite sculptural if they were to be exposed by pruning that is necessary anyway. It really would not take much.

English Holly

90109We all know that holly is famous for holly berries, but in modern gardening, English holly, Ilex aquifolium, is appreciated, or despised, for its distinctively glossy but very prickly evergreen foliage. Like countless tiny thorns, the foliage is too prickly to handle for those who despise it. Those who appreciate it know there is no substitute for the elegantly polished sheen and handsome texture.

The lack of berries is due to a lack of pollinators. Most plants are female, so are capable of making berries. However, until recently, male plants were not even available in nurseries. Old formal hedges of female plants were typically accompanied by a few male plants in less refined parts of the same garden. Some newer hollies are grown with two plants of both genders in the same pot.

Most English holly is rich dark green, even though there are many exquisitely variegated cultivars. Some are variegated with silvery white or creamy white. A few are variegated with lemony yellow or gold. Variegated specimens tend to stay smaller. Unvariegated specimens can slowly grow into small shade trees with less prickly upper foliage, although most are kept less than ten feet tall.

Potted Plants Are Living Things

90109thumbCut Christmas trees really are the way to go. There is no obligation to take care of them after Christmas. They do not need to planted out into a garden that will be too small for them as they grow. They do not need to be maintained in a pot, only to get disfigured or partially defoliated before next Christmas. They simple get removed from the home and composted or otherwise disposed of.

Potted living Christmas trees may seem like a good idea, but they are not as sustainable as they seem to be. Only the smaller and more compact types of conifers can be confined to big pots or planted into compact garden spaces. Rosemary shorn into small cones happens do well either in big pots or out in the garden, and if preferred, can be allowed to assume its natural bushy form.

Many other potted plants that are popularly brought into the home for Christmas decoration are easier to accommodate but take a bit of effort. Poinsettias are the most familiar of these. They can grow as houseplants for years, and might hold their colorful bracts for months. In mild climates, they can be planted in the garden, but will never look like they did originally. Most get discarded.

Hollies and azaleas are more sustainable, but are not as popular. Of these, hollies are the easiest. They can be planted in larger pots or directly into the garden later, when the worst of winter is over. Azaleas will eventually drop their flowers, and will likely look very distressed for a few months, but if watered regularly, can regenerate new foliage that is adapted to their new environments.

Christmas cactus happens to be a delightful houseplant regardless of the season. It will also drop its flowers, but will generate appealing pendulous foliage that cascades nicely from hanging pots. It can bloom annually, although timing of bloom is quite variable. It can do the same outside, if sheltered. Amaryllis also prefers to stay potted. It will replace its tall flower stalks with a few leaves that sustain the bulbs until dormancy next autumn, and can bloom again next winter if given a chance.
