This article gets recycled today because it includes a light duty rant, which almost conforms the ‘Horridculture’ meme that normally posts on Wednesdays.
Kahili Ginger
It is not the ginger that is so popular for culinary purposes, but it is the most popular for home gardens in the West. Kahili ginger, Hedychium gardnerianum, is so vigorous and easy to grow that it has potential to be invasive in ideal situations. Fortunately, it does not produce many of its sticky seeds locally. It therefore migrates primarily by dispersing rhizomes, which are not noxiously fast.
The delightfully fragrant bloom begins late in summer, and will finish soon. As many as forty small pale yellow and red flowers radiate from each cylindrical floral truss. Blooms stand neatly vertical, even if the stems supporting them lean. As cut flowers, they last only for a few days. Deadheading after bloom eliminates unwanted seed (if that is a concern), and unclutters the tidy foliage below.
However, with or without deadheading, the lush foliage is only temporary after bloom. It deteriorates as the weather cools through autumn. Cutting the herbaceous canes to the ground before they get too unsightly will expose some of the thick rhizomes. New canes will grow a few feet tall next spring and summer. On the canes, each leaf extends in the opposite direction of the leaf below it.
Fertilizer Is A Seasonal Commodity
Fertilizer, in simple terms, helps plants grow. It provides a bit more of what growing plants crave. In some situations, it compensates for nutrient deficiencies. Fertilizer can be organic or synthetic. Various formulations serve a variety of purposes. Custom formulations appeal to plants with discriminating taste, such as citrus, orchids and roses. Slow release fertilizer lasts for a month or two.
Of course, proper scheduling of the application of fertilizer is very important. Fertilizer can actually become toxic with excessively frequent application. Fertilizer that provides significant nitrogen to promote vegetative growth after bloom can inhibit floral growth prior to bloom. Fertilizer that promotes root growth for new plants is unnecessary for mature plants. The diets of plants are variable.
Summer lingers later here. Regardless of the weather, it is now autumn. This is when deciduous plants start the process of defoliation for their winter dormancy. Evergreen plants are less obvious about their winter dormancy. Some remain active and even bloom through autumn and winter locally. Nonetheless, cooling weather and shortening days inhibit vascular activity of almost all plants.
Except for cool season vegetables and bedding plants, not many plants benefit from fertilizer applied this late. New plants might appreciate a bit just to help them adjust to their new environment. Some deciduous plants, particularly roses, like a last late application of fertilizer as they get ready for their long winter dormancy. Lawns might want fertilizer this late or perhaps later to stay green.
Otherwise, it is getting late to utilize fertilizer.
Late application of fertilizer can be very detrimental to plants that are sensitive to cool weather. Such plants typically finish growing through summer. By autumn, their mature foliage and stems are either resilient to minor frost, or are dieing back (defoliating) for winter dormancy. Fertilizer can stimulate premature development of new growth that will be much more sensitive to even mild frost.

The Trees Know
This posted in the middle of October three years ago. At the time, it seemed early. It seems to be even early in September. However, because of the weather this last summer, it is actually rather timely.

Six on Saturday: A Bit More Color
Since the Fire, my Six on Saturday posts have been rather gloomy. Titles such as ‘Pompeii‘, ‘Revelation‘ and ‘Revelation II‘ are appropriately descriptive. More color is in order.
1. Silvery bark of a silver maple is sort of colorful. Hey, the next five really are more colorful. I planted this tree as a young twigling in the Santa Clara Valley when I was in high school. It had a second trunk, which I layered as another tree for the front garden. This tree is in back. I would like to get a copy for my own garden. This is now an old picture that I got during evacuation.
2. Orangish red bloom is that of ‘Pollack’ zonal geranium, which is grown more for its very variegated foliage. However, this bonus bloom is on a specimen that reverted to be less variegated.
3. Peachy Peruvian lily looks pink to me, but is not quite as pink as the pink sort. There is a yellow sort here too. They certainly are prolific. In 1986, I worked with these as a cut flower crop.
4. White phlox self sowed here last year or earlier, and have performed splendidly. There are more this year than there were last year. It would be excellent to get a few more for next year.
5. Blue annual morning glory grew up with my tomatoes. Oddly, they did not do so well where their seed were actually sown intentionally, in pots on the deck up above the vegetable garden.
6. This is my favorite picture this week. I can not read what, if anything, is written in paint on this rock. It looks like someone enjoyed painting it, and placing it to be found out in the garden.

Tree Of Heaven
‘A Tree Grows In Brooklyn’ documents the resiliency and invasiveness of the common but typically undesirable tree of Heaven, Ailanthus altissima. Once a single female tree get established, the extremely prolific seeds get everywhere, including cracks in concrete. The resulting seedlings conquer wherever they are not dug out. If cut down, they just resprout from the roots.
Male trees smell horrible while blooming for about a month in spring or summer. They are pollinated by flies, so naturally smell like what flies like. The tiny yellowish or tan flowers hang on panicles that can be a foot and a half long. Female blooms are not as big, prolific or objectionably fragrant. However, stems, leaves and all other parts of both genders smell rotten when handled.
Tree of Heaven, which has earned the alternative names of ‘tree of Hell’, ‘stink tree’, ‘ghetto elm’ and ‘ghetto palm’, is no longer a tree that gets planted by choice. It is typically a tree that plants itself, and on rare occasion, happens to grow into a good situation. They should not be allowed to overwhelm more desirable trees, or get too close to concrete or other damageable features.
Young trees grow very fast to about forty feet tall. Older and slower trees do not get much taller, although sheltered trees can get twice as tall, with elegant gray bark. They do not live much more than fifty years. The big pinnately compound leaves are surprisingly pretty. On vigorous shoots, individual leaves can get as long as two and a half feet, with leaflets as long as six inches.
Leaves Are Starting To Fall
Autumn color is different every year. Sometimes, early and sudden cool weather after a mild summer promotes good foliar color that lingers longer while relaxed trees slowly realize that they should probably start to defoliate. Sometimes, early wind and rain accelerate defoliation of otherwise good color. There are a few variables that trees must adapt their performance to.
Warm and arid weather two weeks ago started the process of defoliation suddenly and a maybe slightly early this year. Even before the weather gets cool, deciduous trees are already starting to shed the oldest of their foliage that they do not need in order to hold their youngest foliage a bit later into autumn. Evergreen trees do the same to limit desiccation.
Slightly breezy weather that was so pleasant after such heat was just enough to start dislodging deteriorating foliage. Now, leaves are already starting to fall before they develop much color. Redwoods and pines are likewise dropping browned needles. Fortunately, trees that are the most colorful in autumn tend to hold their foliage better until the weather gets cooler.
It is impossible to predict how colorful trees will be this autumn; although if storms are as healthy as predicted, the mild temperatures may inhibit color, while wind and rain dislodge colorful foliage. Regardless, it is already time to start raking falling leaves and needles. They can get messy, and when the rain starts, they can stain pavement and clog gutters.
When more foliage falls later in autumn, it will need to be raked from ground cover, surviving portions of lawn, and any other plants that collect it, so that it does not shade out the sunlight.

Hetz Blue Juniper
Some junipers that were so popular in the 1950s are now somewhat rare, or redundant to modern cultivars. Although not as common as it once was, Hetz blue juniper, Juniperus chinensis ‘Hetzii Glauca’ is still practical for modern gardens. Most junipers with such bluish gray foliage are either low and sprawling, or upright and tall. Hetz blue juniper exhibits an elegant outwardly flaring form.
Mature specimens can get taller than six feet, and as broad as ten feet. The dense evergreen foliage is not quite as blue as that of blue spruce, but is nonetheless striking amongst deeper green. Straight stems point sharply outward at about the same low angle, but in all directions. Removal of lower growth from old and overgrown specimens might reveal peeling bark and sculptural limbs.
Established Hetz blue juniper with warm and sunny exposure is nicely undemanding. Occasional irrigation through the warmest summer weather maintains color and foliar density. However, color naturally fades slightly and slowly through summer. If possible, selective pruning should completely remove obtrusive stems from their origins. Otherwise, stubs might compromise the natural form.
