Landscape plant in the context of "Petunia"

Irrigation is the practice of applying controlled amounts of water to land to help grow crops, landscape plants, and lawns. Irrigation has been a key aspect of agriculture for over 5,000 years and has been developed by many cultures around the world. Irrigation helps to grow crops, maintain landscapes, and revegetate disturbed soils in dry areas and during times of below-average rainfall. In addition to these uses, irrigation is also employed to protect crops from frost, suppress weed growth in grain fields, and prevent soil consolidation. It is also used to cool livestock, reduce dust, dispose of sewage, and support mining operations. Drainage, which involves the removal of surface and sub-surface water from a given location, is often studied in conjunction with irrigation.

Several methods of irrigation differ in how water is supplied to plants. Surface irrigation, also known as gravity irrigation, is the oldest form of irrigation and has been in use for thousands of years. In sprinkler irrigation, water is piped to one or more central locations within the field and distributed by overhead high-pressure water devices. Micro-irrigation is a system that distributes water under low pressure through a piped network and applies it as a small discharge to each plant. Micro-irrigation uses less pressure and water-flow than sprinkler irrigation. Drip irrigation delivers water directly to the root zone of plants. Subirrigation has been used in field crops in areas with high water tables for many years. It involves artificially raising the water table to moisten the soil below the root zone of plants.

Pruning is the selective removal of certain parts of a plant, such as branches, buds, or roots.It is practiced in horticulture (especially fruit tree pruning), arboriculture, and silviculture.

The practice entails the targeted removal of diseased, damaged, dead, non-productive, structurally unsound, or otherwise unwanted plant material from crop and landscape plants. In general, the smaller the branch that is cut, the easier it is for a woody plant to compartmentalize the wound and thus limit the potential for pathogen intrusion and decay. It is therefore preferable to make any necessary formative structural pruning cuts to young plants, rather than removing large, poorly placed branches from mature plants.

Philodendron bipinnatifidum, synonyms including Thaumatophyllum bipinnatifidum and Philodendron selloanum, (common names: split-leaf philodendron, lacy tree philodendron, selloum, horsehead philodendron, guaimbé) is a plant in the genus Philodendron, in the family Araceae. The species is native to South America, namely to Brazil, Bolivia, Argentina, and Paraguay, but is also cultivated as a landscape plant in tropical, subtropical and warm temperate climates.

The common name "split-leaf philodendron" is also used for Monstera deliciosa.
