Oleander that inhabits freeway medians is poisonous enough to be hazardous. Two tons of Buick cruising at 65 miles per hour past such oleander has more potential to be hazardous. The risk associated with toxic plants within freeway medians is as limited as their...

Home gardens are becoming shadier. Modern homes are taller to fit closer together. Modern fences are taller to compensate. Densely evergreen trees and large shrubbery compensate more. Taller homes and fences, and denser vegetation, shade more of their smaller modern parcels. Not much sunlight...

A tree is a woody perennial plant with a single tall trunk and branches. Banana trees and tree ferns lack both branches and wood. Arboriform yuccas develop branches but are not woody. Palm trees are no better. Some develop a few trunks but without...

Dormancy is not exclusive to vegetation. Many animals are dormant while they hibernate through cold winter weather. Some animals are dormant while they aestivate through hot and dry weather. Fungi and bacteria can maintain dormancy for many years or centuries. Dormancy is a technique...

Bare root season begins as the year ends for a simple reason. That is when deciduous plants are dormant. They are unaware of the otherwise distressful process of relocation. This is also why winter is the season for dormant pruning. Such pruning would be...

Pruning at the proper time has been a concern all winter. Dormant pruning was timely as soon as defoliation began. It remains timely almost until bloom. Pollarding and coppicing are generally although unnecessarily a bit later within that range. Spring pruning begins soon after...

All weeds are plants. Not all plants are weeds. Weeds are a specifiable subset of plants. Specifically, weeds are plants that grow wildly where they are undesirable. Similarly, dirt is likely soil, although it could be anything that is dirty. Soil is not merely...

Indian Summer complicates autumn. It is an imposition of pleasant weather that delays inevitable chill. Gardening is a bit more enjoyable while the weather remains summery. However, late warmth confuses a few species that should decelerate growth for autumn. Deciduous species delay dormancy. This...

Some of the earliest of spring flowers are done blooming. More are just beginning. Then, a few early spring flowers barely qualify as early. Their fresh color is especially pleasing after such an atypically wintry winter. Many are delightful cut flowers. A few that...

Ferns are foliar perennials. They provide neither floral color nor fragrance. They provide neither fruits nor vegetables. With few exceptions, they provide no shade. The very few that are deciduous are not impressively colorful for autumn here. Ferns can not grow as hedges. Nor...
