Vines For Better Or Worse
UNITED STATES—Vines in the wild are downright exploitative. They do not support their own weight, so instead climb or sprawl over shrubbery and trees. Some are satisfied staying down below the canopy of the hosts who support them, as if aware that a healthy host will support them for a good long time. Many vines climb aggressively to the...
Deadheading Promotes And Prolongs Bloom
UNITED STATES—April showers bring May flowers. May flowers make a mess. Well, some of them do. Most simply disintegrate and fall from the trees, shrubs and vines that produced them, and decompose into the soil below. Some might have needed to be swept off of pavement and decks. Regardless, most of us do not notice the very minor consequences...
Spontaneous Limb Failure Is Real
UNITED STATES—It sounds like science fiction, but it is not. Every spring and during particular summer weather, limbs can fall from trees without warning, and seemingly for no reason at all. It happens when least expected, while the weather is warm and perhaps humid, but notably without wind. The lack of wind is what makes it so unexpected. It...
Some Annuals Are Really Perennials
UNITED STATES—Annuals are plants that complete their entire life cycle from germination to death within a single year. Biennials complete their entire life cycle in two years, mostly by developing vegetative growth during their first year, and then blooming, producing seed and then dying after their second year. Perennials are the many herbaceous plants that survive longer than just...
Mighty Oaks From Little Acorns
UNITED STATES—Oak, which might seem to be obvious to many of us, was identified by the Arbor Day Foundation as the People's Choice for American's National Tree. We certainly like our redwoods and exotic palms in California. Quaking aspen and blue spruce are probably favorites in Colorado. Sugar maple must be the most popular in Vermont. Yet, everyone appreciates...
Nomenclature Is More Than Botanical
UNITED STATES—Simply put, 'nomenclature' is how things get named. It is not exactly like naming a child or a dog, or even a new small country in the South Pacific. There is a certain technique to it that is more like naming cars. Well, it 'was' like naming cars, a long time ago when cars had simple names rather...
Naturalizing Within Constraint Of Cultivation
UNITED STATES—Pampas grass, blue gum eucalyptus, giant reed, broom and Acacia dealbata are some of the best examples of the worst naturalized exotic species. They were imported for a variety of reasons or by accident, and now proliferate aggressively in the wild. With few of the pathogens they contend with in their respective native homelands, they have unfair advantages...
Citrus On The Sucker List
UNITED STATES—A five pound kumquat is a problem! It means something went seriously wrong. Anyone who grew one would concur. They are huge, lumpy, and very insipid, with ridiculously thick pale yellow rind around a small handful of uselessly fibrous pulp. They are protected by dangerously sharp and rigid thorns that can get longer than three inches. Even their...
Gophers Go For Spring Vegetation
UNITED STATES—Hibernation is a luxury enjoyed by different animals in different climates, where much colder weather inhibits activity through winter. Gophers take no such extended time off here. They merely work less diligently through the cooler and rainier times, and maybe get out of the way if the soil they live in gets too saturated. Their minimal damage had...
Citrus And Avocado From Seed
UNITED STATES—Is it possible to grow citrus from seed? The quick and simple answer to that question is, “Yes.” After all, many cultivars of citrus were originally bred from other cultivars, and then grown from seed. But of course, this an overly simplified answer to an unrealistically simple question about a surprisingly complicated process. Perhaps a better question is...
