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".

Thrips on plants in your garden or indoors can cause a lot of damage. Here's how to stop these pests with simple organic techniques. Prevent Thrips on Plants Naturally with These 10 Must-Know Tips
A plant that produces root sprouts or runners is described as surculose. [1] Water sprouts produced by adventitious buds may occur on the above-ground stem, branches or both of trees and shrubs. Suckers are shoots arising underground from the roots some distance from the base of a tree or shrub.
Sprouting is the natural process by which seeds or spores germinate and put out shoots, and already established plants produce new leaves or buds, or other structures experience further growth. In the field of nutrition, the term signifies the practice of germinating seeds (for example, mung beans or sunflower seeds ) to be eaten raw or cooked ...
Periphyton can contain species of cyanobacteria that are toxic to humans and other animals. [1] In fresh water, excessive growth and subsequent death and decay of periphyton can have undesirable effects: depleting oxygen in the water, altering its pH, and clogging the space between gravel and sand (the hyporheic zone).
Scarification is often done mechanically, thermally, and chemically. The seeds of many plant species are often impervious to water and gases, thus preventing or delaying germination. Any process designed to make the testa (seed coat) more permeable to water and gases is known as scarification.
A silver vine plant with the eponymous silver markings on its leaves. Actinidia polygama (also known as silver vine, matatabi and cat powder) is a species of kiwifruit in the family Actinidiaceae. It grows in the mountainous areas of Korea, Japan and China at elevations between 500 and 1,900 metres (1,600 and 6,200 ft).
Cleaning is often done at a later stage, to allocate growing space to selected individuals that have demonstrated superior quality. This usually means a straight trunk that will make a good saw log, or perhaps a healthy crown on a mast-producing tree. In any case, desirable qualities have been identified in each particular tree, and competing ...
