Fall For Spring Bulbs Now

61019thumbThey are certainly not much to look at now. They are even less interesting once buried out of sight in the garden. The big and colorful pictures on the boxes that they arrive in are probably a bit more spectacular than the flowers expected early next spring will actually be. Nonetheless, it will be amazing to see such flashy bloom emerge from seemingly lifeless bulbs that get planted now.

Dormant bulbs are so easy to plants precisely because they are dormant, and therefore lacking any foliage, bloom or roots that can be damaged in the process of planting. They only want to be planted at the right depth, and preferably in the correct orientation (with their tops up and their bottoms down). They like to be planted now, so that they can slowly chill through cool winter weather.

Chill through winter is important to convince dormant bulbs that it really is winter. In such a mild climate, some plants might wonder about that. Cool winter weather either initiates the development of blooms within dormant bulbs, or stimulates bloom as weather subsequently warms. Many tulip, hyacinth, anemone and ranunculus might not get enough chill here to bloom after their first year.

Daffodil, narcissus, grape hyacinth and some iris are not so discriminating. They are likely to bloom even better in their second spring, and can naturalize in good soil with occasional watering. Freesia and crocus might also naturalize, but want more water. Crocosmia and montbretia can actually be invasive. Dahlia and gladiola are summer bulbs, so will be available for planting later.

All bulbs, as well as the corms, rhizomes, tubers and tuberous roots that are commonly known as bulbs, become available in nurseries when it is time for them to be planted, for obvious reasons. Some will be available for quite a while, so can be planted in phases every two week or so, like vegetable plants. Each subsequent phase starts to bloom as each previous phase finishes bloom.

Phasing only works for certain bulbs that are on a tight schedule, and only for the first season. By the second year, they will be synchronized. Iris, anemone and ranunculus tend to bloom together, when the weather is right, regardless of when they were phased. Plants with aggressive roots might not bother bulbs in their first season, but can smother bulbs that might otherwise naturalize.

Fall

P81013I prefer to call it ‘autumn’. It sounds prettier. Perhaps it even sounds a bit more exotic, like something that happens in far away climates were the seasons are more distinct, and the weather gets a bit cooler this time of year.
‘Fall’ sounds more like a simple verb. It is merely what outdated leaves do when deciduous trees no longer have use for them. Many trees in mild climates do not even bother to indulge their foliage with a bit of color first.
Exotic places like Pennsylvania, Minnesota and Kentucky get autumn. Oklahoma, Oregon and Alaska get it as well, although it is commonly mistaken for fall because the deciduous foliage of most native specie turns brown in Oklahoma, and yellow in Oregon and Alaska, with significantly less of the oranges, reds and other bright colors that are so prominent in other regions.
Rather than complain about the minimal variety of color among out native specie, and how the best color is provided by very accommodating exotic specie that color well even in our locally mild weather, I prefer to brag about how excellent the weather is through our fall. Except for the longer and cooler nights, our fall is like an extension of summer. It is often referred to as Indian summer. While others share pictures of their colorful autumn foliage, I get to share pictures of fall roses that continue blooming until frost,or even right through winter. Yes, in some regards, fall can be better than autumn.
Then, this happened. While dahlia, zinnia, black-eyed Susan and even rose continue to bloom for those whom I would otherwise shame with my superior blooms, fall moved in, and is already defoliating a few trees! Sweetgum is starting to turn orange and red, but cottonwood, box elder, various willows and other riparian trees are beginning to defoliate without much color at all. This black oak is significantly farther along. At least it turned a nice rusty brown before defoliating.
How embarrassing! I can brag neither about extended bloom through a late fall, nor the bright foliar color of autumn!P81013+

Six on Saturday: Clearance

 

Clearance can get one into some interesting situations. Yes, with the necessary clearance, one can get into penitentiaries, protected military facilities, sensitive areas of the White House, or even Area 51.

The sort of clearance that I was concerned with this past week and the week prior was not so interesting. Now that roofs and gutters of the buildings at work are in the process of being cleaned before wintry weather, trees must also be pruned for clearance. As they grew through summer, some got detrimentally close to the roofs and gutters that are getting cleaned, as well as chimneys, windows, outdoor lighting and walkways. Such clearance is a concern throughout the year, but becomes more of a priority as we get ready for winter. No one wants to go back onto the roofs any more than necessary.

1. Before. The redwoods must be pruned for adequate clearance from the roof, chimney, lamppost, and even the umbrella on the patio that can not be opened without pushing a bit of foliage aside.P81013

2. After.P81013+

3. Soot on the tip of one of the redwood limbs demonstrates why clearance from chimneys is so important. Foliage that gets too close to chimneys can ignite and fall back onto the roof below, where it has the potential to ignite any foliar debris that might have accumulated behind the chimney since last year.P81013++

4. The belfry of the chapel next door really bothered me. Clearance was barely adequate. Although I am not worried about the shingles or painted surfaced getting damaged as wind starts to blow during winter, I think that the chapel would look better with more clearance from the encroaching redwood limbs. The problem was that I could not reach the limbs. Because this clearance was not a priority, the pruning here was postponed. A colleague who is not as plump as I am suggested that I get onto the roof through that gap between the top of the louvered sides of the belfry, and the underside of the roof above. Now, even if I could somehow get through that little gap, where would I go on the outside?! Let Quasimodo do it!P81013+++

5. The chapel was built among the redwoods, very literally. Expanding trunks are beginning to displace the foundation and utilities. I can not prune for the sort of clearance that is needed here. Because the chapel is such an important building, and the redwoods are such important trees, it would be feasible to move the chapel over onto a new foundation. The problem with that idea is that the redwood trunks are pressing up against the building on three sides! There is no place to move the building without cutting something out!P81013++++

6. Phytophthora ramorum, which is commonly known as Sudden Oak Death Syndrome, or SODS, continues to kill tanoaks, (Notho)lithocarpus densiflorus, and coast live oaks, Quercus agrifolia. These trees do not need to be pruned for clearance, but must be removed before they start to deteriorate and drop limbs onto adjacent buildings or whatever happens to be below.P81013+++++

Mexican Bush Sage

51014In the first year, Mexican bush sage, Salvia leucantha, does not get very big. Then it gets cut back to the ground at the end of winter. It gets about twice as big in the second year, only to get cut back again as winter ends. By the third or fourth year, healthy maturing plants can grow to five feet tall and seven feet wide each season. While cut back, big clumps can be divided to propagate.

Strikingly purplish blue floral spikes bloom from summer or early autumn until frost. The odd white ‘tags’ that protrude from the fuzzy bracts are the true flowers. The lanceolate leaves are grayish sage green and somewhat fuzzy. Plants are well rounded like tumble weeds, and should not be shorn. Mexican bush sage is very popular among hummingbirds, butterflies and bees.

Mexican bush sage wants full sun exposure, and unlike most other sages, it prefers relatively rich soil. Fertilizer can compensate for inferior or dense soil, and improves foliar density, but too much can delay bloom. New plants like to be watered regularly, especially if they grow well. As they mature and disperse their roots, they become less reliant on regular watering.

The Right Bulbs Save Energy

51014thumbAfter working so hard to bloom so impressively in spring or summer, bulbs redirect their efforts into saving up their energy for winter dormancy. That is why their fading foliage lingers after faded flowers get pruned away. The foliage eventually dries and deteriorates, leaving plumped dormant bulbs to overwinter underground. It is all their natural life cycle.

However, to bloom well the following spring, many bulbs need to be chilled while dormant. Such bulbs are from cooler climates. The chill convinces them that it really is winter, and that it will be safe to bloom when weather gets warmer in spring. They can get rather confused without adequate chill. Some may never bloom as well as they did their first spring.

Tulip, hyacinth, lily, anemone and ranunculus are probably the best examples of the worst perennial bulbs. Technically, they are perennials. Where winters are cooler, they may naturalize and bloom every spring. Here, winters are just too mild. They bloom very impressively in their first spring, but rarely bloom as well the second spring, and only if pampered.

Narcissus, daffodil, grape hyacinth and bearded iris are much more reliable. Crocus and freesia are a bit more demanding, but can be reliable if they get what they want. Montbretia and crocosmia are reliable enough to become invasive. Gladiola and dahlia, which are not quite as reliable as crocus, are summer bulbs, so get planted a bit later.

Of course not all bulbs are true bulbs. Some are corms, rhizomes, tubers or tuberous roots. Some get planted deeply. Bearded iris and a few others get planted shallowly. A few others do best in pots. In their first year, some bulbs can be planted in phases so that they bloom in phases the following spring. However, all bulbs of each type will synchronize by their second year.

Anemone, ranunculus and bearded iris bloom too synchronously to be phased. No matter when they get planted, each type blooms at the same time. However, some bearded iris bloom as early as the earliest of daffodil, and others bloom late. Some even bloom twice!

Horridculture – Lessons From Motivational Posters

P81010I work for the best. I do not intend to be too terribly pompous about it. I am just being honest.
This is not first time I have worked for the best. I have worked for at least three of the best arborists in the Santa Clara Valley, and two legendary horticulturists. I intend to eventually return to work for one of those legendary horticulturists back on the farm.
The main work I do now is part time and temporary. That means that I work less than four days each week, and will not be working there forever. I try to not think about leaving because it is saddening. I enjoy those whom I work for so much.
I work for only one other horticulturist, and one who is studying to be an arborist. Neither of them grow any significant quantity of nursery stock like I intend to spend the rest of my career doing. They maintain landscapes and facilities. The others of our elite group are very specialized professionals who work with everything else that is not relevant to horticulture. One is a carpenter. One is an electrician. One is a plumber; and so on. Although impeccably specialized, any one of us would do what he must to accomplish whatever needs to be done, even if it is beyond his respective specialty. Collectively, we are the ‘maintenance staff’.
How is this relevant to horticulture? I suppose it is not very relevant. However, everyone else on the maintenance staff respects what the other horticulturist, the other arborist, and I do. Anyone who needs vegetation pruned for clearance from a project contacts us to get it done properly. Anyone who sees obvious problems in the landscape informs us about them. Everyone on the maintenance staff respects everyone else and their respective professions.
To describe what makes the maintenance staff the best, I could use any combination of those inspirational words that are so ungraciously followed by an overly simplified dictionary definition on those insultingly inane motivational posters that so many other employers display prominently in the workplace. They are all relevant. However, we have nothing to prove.
Besides, this is not about the best. It is Wednesday, when I write within the context of my ‘Horridculture’ theme.
I have also worked for the worst. One of these worst was portrayed to be a very professional landscape maintenance company. We had a much larger staff, spread out over nine counties. We had a good variety of those motivational posters in our main office. Unfortunately, I did not realize when I went to work there, that those posters merely defined what we lacked.
Integrity – Dedication – Perseverance – Discipline – Teamwork – Excellence – Strength – Endurance – Accountability – We had none of that. I was the only horticulturist in the big staff of a big landscape maintenance company that simply did not care. I do not know how to describe it more accurately. We simply did not care. We were there to make a buck any way we could. We swindled, cheated and lied. I was only there as their token horticulturist and arborist, to help them get away with more of their illicit activity, and to make a good impression for their victims.
It is so backward. The big and seemingly reputable landscape maintenance company has less regard for horticulture than a maintenance staff who has other completely different priorities.

Dwarf Carnation

81017The three most popular specie of Dianthus are sweet William, garden pink and carnation. Sweet William and garden pink are light duty perennial bedding plants that are often grown as annuals. Carnation blooms are more familiar as fragrant cut flowers than as home garden flowers. Then there is dwarf carnation, Dianthus caryophyllus, that combines the best characteristics of all three.

Unlike the varieties of carnation that are grown for cut flowers on long stems, dwarf carnations do not need to be staked. Their compact growth gets only about five or six inches tall, and not much wider; so they are delightful summer and autumn annuals, or short term perennials like sweet William and pink. Yet, the two inch wide flowers are fragrant and as colorful as cut flower carnations.

The double or semi-double flowers can be white, pale yellow, pale orange, maroon, scarlet, red, peach, rose, or most popularly, various hues of pink. Bloom begins late in spring and continues through autumn and almost until winter. Stray flowers can bloom anytime. The narrow leaves are slightly bluish green, with an almost rubbery texture. Deadheading keeps well blooming plants tidy.

Cool Season Annuals Are Next

81017thumbGardening is not always fun. After diligently tending to warm season vegetables through spring and summer, it eventually becomes necessary to pull them up to relinquish space for cool season vegetables that grow through autumn and winter. It likely would be less unpleasant to wait for them to succumb to frost, but by that time, it would be getting late for the incoming vegetable plants.

Removing warm season annuals and bedding plants is just as necessary, and might be just as unpleasant. The only consolation is that the incoming cool season annuals and bedding plants are likely to be blooming well as they get installed. Even though they take a while to mature, there is no time without at least some degree of color. Warm season annuals may be tired by now anyway.

Just like cool season vegetable plants, the various cool season annuals and bedding plants appreciate an early start so that they can begin to disperse roots while the soil is still somewhat warm. Only those that dislike warmth should wait. Cyclamen and flowering cabbage and kale can be planted as late as winter. Flowering cabbage and kale might even bolt if they get too warm too soon.

Pansy, viola, sweet William, stock, Iceland poppy, calendula and various primroses are all seasonable now. They should be happy to bloom until they too need to be replaced by annuals for the following season, several months later. Chrysanthemum, marigold and a few other autumn annuals are short term annuals that bloom excellently through autumn, but are not likely to bloom later.

Just like most of the cool season vegetables, most of the cool season annuals should be planted as small seedlings in cell pack. Chrysanthemum and many of the primroses, as well as cyclamen and flowering cabbage and kale that come later, should actually be planted as four inch potted plants. Needless to say, some of these are expensive relative to their respectively limited bloom seasons. Seed for nasturtium and alyssum can be sown directly into the garden. Nasturtiums seedlings in cell packs are expensive and do not transplant well.

Cabbage

61012There are those of us who can grow cabbage well, and there are the majority of us who wish we could. Mild winters allow cabbage to be grown in autumn as well as in spring; but warm weather can also compromise flavor and promote premature bolting (blooming), which ruins the heads. Cabbage demands rich soil and regular watering. If the weather is evenly mild, they dig that too.

Spring grown cabbage was planted last winter, about a month prior to the last frost. Now it is time for autumn cabbage, about a month or two before frost. New plants can be planted a bit deeper than they were originally grown, so that the wiry and fragile sections of stem below the lowest leaves can be buried. Plants should be at least a foot apart and might get larger with more space. It takes at least two months for dense round heads of common green or red cabbage to mature. Slower varieties are worth growing for their unique flavors.

The Great Pumpkin

P81007The Third Day of Creation was when it all started. Plant life was created just two days after Heaven and Earth, and Night and Day. It must have been a pretty big deal. Humans were not created until three whole days later!
After all this time since Creation, the flora of the World is still just as important as it has always been. Vegans can survive without the consumption of animal products, but no one can survive without the consumption of plants, or the consumption of animals who were sustained by plants. We breath oxygen generated by plants. We live in homes made of wood. We wear clothes made of cotton. Until relatively recent history, wood was the primary fuel for cooking and warmth through winter. Even modern fossil fuels that have replaced wood are derived partly from fossilized plants. There seems to be no end to the long list of what plants do for us.
As if all that were not enough, plants provide pleasure. Some are dazzling desert wildflowers. Some are majestic forest trees. Most are something in between. Many are invited to inhabit our gardens, landscapes and even our homes and offices. Some are bred to do what they do even better than they did originally.
David Paul, in the picture above, made a career of cabinetry, which involved all sorts of fancy and exotic woods. Most of these woods were derived from genetically unimproved trees that would have been found growing in the wild. Most were from eastern North America. Some were from other continents. Some of the favorite maple burls were specifically from New England and the Pacific Northwest. David Paul was no horticulturist, but he knew quite a bit about the flora that produced the fancy woods that he worked with.
The pumpkin is another story. David Paul grew giant pumpkins for several years in Colorado Springs merely because he enjoyed doing so. It required serious dedication throughout the entire long growing season. Yet, the pumpkins were grown only for the fun of competition. As huge as they were, they were not to be eaten. That is the epitome of growing something merely for the fun of it. This is such an excellent picture of that epic pumpkin that it was the illustration for the obituary of David Paul.
