Herbicides are often used in these cleaning operations because the correct chemical at the correct dose (e.g. glyphosate or triclopyr) and time will kill only broad leaved species, leaving the conifers unharmed and free to grow. Chemical treatments may be applied by foliage sprays, mists or pellets.
Small trees grown in containers, like bonsai, require specialized care. Unlike most houseplants, flowering shrubs, and other subjects of container gardening, tree species in the wild generally grow individual roots up to several meters long and root structures encompassing hundreds or thousands of liters of soil. In contrast, a typical bonsai ...
An apple tree sprout is being converted to a branched, fruit-bearing spur by an arborist. Numbers show the sequence of cuts, which occurred during two years. Plants form new tissue in an area called the meristem, located near the tips of roots and shoots, where active cell division takes place.
(Click for video) Tree care is the application of arboricultural methods like pruning, trimming, and felling/thinning [1] in built environments. Road verge, greenways, backyard and park woody vegetation are at the center of attention for the tree care industry. Landscape architecture and urban forestry [2] [3] also set high demands on ...
In botany, a root sprout or sucker is a severable plant that grows not from a seed but from the meristem of a root at the base of or a certain distance from the original tree or shrub. Root sprouts may emerge a substantial distance from the base of the originating plant, are a form of vegetative dispersal , and may form a patch that constitutes ...
Phytoremediation technologies use living plants to clean up soil, air and water contaminated with hazardous contaminants. [1] It is defined as "the use of green plants and the associated microorganisms, along with proper soil amendments and agronomic techniques to either contain, remove or render toxic environmental contaminants harmless".

More recently, forest managers have found that clearcutting oak stands helps regenerate oak forests in areas of poor soil. The tree canopies in oak forests often shade out the ground, making it impossible for newly sprouted oaks to grow. When the mature trees are removed, the saplings stand a chance of recruiting into the forest. [30]
