Roses Get Pruned In Winter

30508thumb++Winter is no excuse to be less diligent in the garden. It would seem that gardening would be less demanding because there is less going on, and so many plants are dormant. However, dormancy is precisely why there is so much to do through winter. Bare root plants and bulbs are planted because they are dormant. Fruit trees get pruned because they are dormant. Now it is time for roses.

Just like fruit trees, modern roses were intensively bred for enhanced production. Their flowers are too big and abundant for overgrown plants to sustain. Consequently, aggressive specialized pruning is necessary to concentrate resources and promote vigorous growth. Rather than producing an abundance of inferior blooms, well pruned canes produce fewer blooms of superior quality.

Also like deciduous fruit trees, roses should be pruned while dormant, preferably after defoliated, and before new buds swell. This sounds easier than it really is. Some roses might still be trying to bloom on canes from last year. Others might be trying to generate new foliage for this year. Fortunately, they are tougher than they look. Besides, early or late pruning is better than no pruning.

Hybrid tea, floribunda and grandiflora roses need the same sort of pruning. They all should be pruned back to only a few canes that grew last year. Older canes should be pruned out completely, unless there are not enough new canes that grew last year. Hybrid tea and floribunda roses need only three to six canes, only about two feet tall. Floribunda roses might have a few more canes. Tree roses should be pruned just like shrub roses, as if the upper graft union is at ground level. The canes can be pruned shorter.

Suckers from below the swollen graft union (from where canes emerge) should be removed completely. If possible, they should be pulled or peeled off instead of cut. This seems harsh, but leaves less of a stub from which more suckers might develop later. Because fungal spores and bacterial diseases overwinter in decomposing foliage, fallen leaves should be raked from around roses.IMG_20140331_112633

Ecclesiastes 3: 1

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 a manner that is visible or notable from outside. Shedding browned or blackened dead foliage, particularly that which is obscured by new foliage, does not count.

This English ivy foliage is the sort that should not color at all. Old leaves should whither and deteriorate once obscured by new foliage. Perhaps the vine is concentrating resources elsewhere while abandoning this section. Perhaps the entire vine is deteriorating. From this picture, it is impossible to determine why this colorful foliage is exposed.

Perhaps this is the time to just appreciate nice autumn foliar color wherever and whenever we get it, even if it is on English ivy in winter. As the flowering cherries try to convince us that it is spring, that would be just fine too. This can be the time for autumn, spring, and maybe even winter if it ever arrives, all at the same time.

Candelabra Aloe

70201As a group, aloes really deserve more respect. Many will naturalize and thrive with only occasional watering through summer. Candelabra aloe, Aloe arborescens, wants a bit more water than most other aloes, but not much. It looks like a sensitive jungle plant, but is surprisingly durable, and very easy to propagate. Any pruning scraps can be plugged wherever new plants are desired.

The foliage alone is striking. Some might say that the loosely arranged foliar rosettes are sloppy. Others might say they are sculptural. The long and curved leaves are outfitted with prominent but soft marginal teeth. Some specimens have narrower leaves that are almost curled. ‘Variegata’ is striped with creamy white. Mature plants may form dense mounds more than six feet high. Hummingbirds and bees really dig the flashy bright reddish orange floral trusses that bloom on tall stems in winter.

Bulbs Are Not Finished Yet

41015thumbIt might seem creepy to think about what spring bulbs are doing right now out in the garden. Like victims of a horror movie, they were buried in shallow graves last autumn. They were not dead though. They were undead but merely dormant. While no one can see what they are up to, they disperse roots and begin to push new foliage up to the surface of the soil. Some might bloom soon.

Now it is getting to be time for summer bulbs. Unlike spring bulbs, summer bulbs do not prefer to hang out in the garden through the cool and rainy weather of winter. If planted too early, they can start to grow prematurely, and could potentially get damaged by frost. If planted much too late after winter rain, they will need to be watered more carefully while young, and are likely to bloom late.

Just like spring bulbs, most summer bulbs are really corms, rhizomes, tubers or tuberous roots. Only a few are actual bulbs. Although they are very different physiologically, they perform the same function. They store resources from a previous season through dormancy in order to sustain growth for the next season. Some summer bulbs bloom more than once annually or with many blooms.

Dahlia, canna, crocosmia, hardy orchid (Bletilla) and the old fashioned big white calla are some of the easier to grow summer bulbs. Dahlia is the most colorful, but blooms late in summer or early autumn, and might only perform well for a single summer. With regular watering, canna can grow like a big weed, but in a nice way. The others can grow well enough to get invasive over the years.

Gladiolus and lily will probably bloom for only one summer, but are so colorful that those who enjoy them do not mind. Tuberous begonia is fussier, so is usually grown in pots. Allium, astilbe and maybe liatris have potential to thrive and multiply in the right conditions, but more often bloom for only a few years. Small colored callas are unpredictable too. They are showy but rarely prolific.

After bloom, deteriorating flowers should be pruned away to conserve resources while lingering foliage recharges bulbs for the next winter. This process is known as ‘deadheading’. Gladiolus, lily and any others bulbs that bloom only once obviously need to be deadheaded only once. Dahlia, canna and others that bloom over an extended season will want to be deadheaded a few times.

RATS!

P80204

Remember the Beverly Hillbillies? That was a really lame sitcom; but it was somehow very popular at the time.

Each episode began with the stupid jingle that explains how and why the formerly impoverished but suddenly wealthy Clampetts left their home in Bugtussle and moved to Beverly . . . Hills that is.

As they drive their decrepit Oldsmobile down Bedford Drive just west of downtown, the palms flanking the roadway are prominently visible to the left and right. This strictly regimented collection of Canary Island date palms alternating with Mexican palms was not very big back then, in the early 1960s. By the 1980s, they were strikingly grand. Sadly, they are now deteriorating from old age. Many of the broad Canary Island date palms have succumbed to pink rot, so are now absent. Some of the Mexican fan palms are also lacking. It is saddening to see them now knowing how grand they were not too long ago. Although they are being replaced, they will never be as formal and uniform as they were as a monoculture (or biculture) that was planted all at the same time back in the late Victorian period. Even if it were possible to remove all of the trees and plant new ones at the same time, such conformity went out of style decades ago.

Arborists see these historic trees differently. They know that just one Canary Island date palm is likely infested with rats. Such a grand collection must be infested with a disturbingly large population of rats. Within a canopy of a Canary Island date palm rats, are safe from most predators, and get quite a bit to eat from the fruit produced by the female trees. (Most Canary Island date palms are female, with only a few taller and less billowy male trees for pollination.)

When a Canary Island date palm gets cut down from the base, it falls with a big SPLAT on the ground, followed by a blast of wind containing every Frisbee, baseball, tennis ball, kite and whatever got stuck in the tree over the previous few years. After a brief pause, but before the the baseballs stop rolling in the gutters, a herd of all surviving rats flees the scene. Most hide in the closest shrubbery they find. Some scurry up other nearby palms. It can really blow your image of the Canary Island date palm.

Sesame Street Was Wrong!

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 was fascinated with the trees.

I certainly did not need Sesame Street to show me how excellent my first silver maple was. It was my second tree, after my incense cedar. My mother thought of it as ‘her’ maple tree. Yeah, right. When it defoliated in autumn, I ‘raked’ the leaves by pairing them all up, and then pairing all the pairs into groups of four, and then pairing the groups of four into groups of eight, and so on, until there was only a single pile of leaves. When the tree was very small, it had only about sixty-four leaves, so this technique worked just fine. It was a bit more work by the second autumn. By the third autumn, I had learned how to use my little leaf rake.

During this time, I happened to learn something from Sesame Street that I had not previously known about maple trees. They make maple syrup! The kids who lived near the forest in New Hampshire went with their father out to where their maples were, to collect syrup. It was simple. The father gouged the bark, drilled a hole into the trunk, stuck a hooked device into the hole, and hung a bucket onto the hook to collect they syrup! I do not remember if that was the correct sequence of events; but how difficult could it be? The video was only a few minutes long, so I knew that it did not take long for the bucket to fill will with syrup that the kids poured over their pancakes at the end of the video.

What the video failed to explain adequately is that after the bucket was hung, it was left there overnight, and was retrieved the next day. To me, it looked like the kids got distracted and left, but then came right back a few seconds later. The video also failed to explain how involved the process of concentrating the sugar by boiling off the water from the sap. Again, to me, it looked like a pot of boiling sap was ready for pancakes a few seconds later. Like I said, the video was only a few minutes long.

Getting syrup from the maple tree was just too tempting. I took my little plastic beach pail and a small hatched for kindling and went out to get my own syrup. I smacked the trunk with the hatches and grabbed my pail to catch the sap that was supposed to come pouring out; but nothing happened. I smacked the tree again; but again, nothing happened. I gashed the trunk a few more times, in various spots around the trunk, but never got any syrup. Eventually, I got distracted with something else. I left my pail and the hatchet there next to the tree, believing that Sesame Street was wrong.P71231+

Late Cotoneaster

80214The bright red berries of late cotoneaster, Cotoneaster lacteus, that ripen in autumn may not be as profuse or as bright red as those of firethorn, but they last longer, and even into winter. Birds strangely seem to avoid them. Although the clustered small berries can look just like firethorn berries, they are usually less shiny, and darker red. Clusters of tiny pale white flowers bloom in spring. The small evergreen leaves have a nice glossy and veined texture on top, with hazy gray or tan tomentum (fuzz) below. The grayish brown bark of old stems resembles that of apple or pear trees.

Tall arching stems can get just tall enough to reach first floor eaves, or taller if they happen to be shaded or leaning onto other larger shrubbery for support. In full sun, growth is more dense. Mature plants get a bit broader than tall. Unlike firethorn, late cotoneaster lacks thorns, which make it easier to work with as an espalier or informal hedge. Growth is a bit too irregular for a formal hedge.

Established plants do not need much water, and in some situations can do well without any watering. Unfortunately, late cotoneaster has naturalized as an invasive exotic weed in some regions.

Colorful Berries Feed Overwintering Birds

80214thumbPlants compensate for their immobility by procuring the services of animals and insects. They bloom with flowers that attract pollinators with colors, fragrances and flavors. Their fruits use similar techniques to attract those who consume the fruits to disperse the seeds within. It is a pretty ingenious system. The animals and insects probably think that they are taking advantage of the plants.

Firethorn, toyon, cotoneaster, English hawthorn and the hollies all produce profusions of small bright red berries that are designed literally for the birds. They are just the right size for birds to eat them whole. If they were smaller, birds might prefer other fruits. If they were any bigger, birds might eat them in pieces, and drop the seeds. The bright red color is a blatant advertisement to birds.

Firethorn is probably the most prolific with its berries. It might also be the most popular with the birds. If the colorful berries are not gone yet, they will be soon. Toyon berries seem to last longer, perhaps because they do not all ripen at the same rate. Because it gets big and takes some work to contain. toyon is more common in unrefined landscapes and in the wild than home gardens.

English hawthorn and cotoneaster are variable. Some varieties are more productive with berries than other are. Some types of English hawthorn are grown more for their bloom or foliar color in autumn. They are deciduous, so their berries hangs on bare stems. Late cotoneaster produces more berries than other cotoneasters, and somehow manages to keep its berries late into winter.

Holly is not related to firethorn, toyon, cotoneaster or English hawthorn, which are all in the Rosaceae family, although the bright red berries suggest that it should be. Because most holly plants are females that lack a nearby male pollinator, berries can be scarce. Some plants in nurseries are actually two plants together in the same pot, one male and one female, to ensure adequate pollination and berry production. Deciduous hollies are unfortunately rare.

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

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 . . . even though everyone else was doing it too.

Some people believed that gardens and houseplants were healthier if they were regularly engaged in conversation. Some of us would say that this is true only because those who talk to their gardens and houseplants are more involved with them, and are therefore more attentive to their needs. That makes sense. Otherwise, the theory has been neither confirmed or disproved by any reliably documented data.

I do not need data. My gardens did quite well with this technique. So did many of the annuals, perennials and trees I got to plant back then. The little disfigured Monterey pine that I met on my way to school ( https://tonytomeo.wordpress.com/2018/01/01/new-year-old-school/ ) is still doing well, long after all the others that I did not converse with are gone.

Makrut Lime

80207Of all the weird citruses available, this is one of the strangest. Makrut lime, Citrus hystrix, is not grown for its ugly wrinkled fruit. The rind and the juice are only rarely used for culinary or medicinal purposes. The important part of makrut lime is the aromatic foliage, particularly the modified petiole ‘wings’ that look like leaves. Fresh or dried, they are popular in the cuisine of Southeast Asia.

Mature trees can eventually reach second story eaves, but are usually kept significantly lower. They are so shrubby that even large trees should have plenty of foliage within easy reach from the ground. Once a tree gets overgrown, it is not as easily pruned lower as some other citrus trees are. Pruning stimulates vigorously long and arching stems, rather than more desirable fluffy growth.

The winged petioles are almost as long and wide as the actual leaves are. In fact, they look just like the leaves, making them look like ‘double leaves’. Although the petiole wings separated from the petiole are supposedly the most aromatic parts, leaves are useful too. The hard fruits are about as big as golf balls, and are the same rich green as the foliage, until they ripen to a light yellow.
