Woody:
Plants with hard, tough tissues (stems), oftentimes unsightly, as part of the structural support. Often the main stems and large roots are woody and the other stems are softer tissue. Most woody plants are perennials and include deciduous trees and shrubs, evergreen trees and shrubs, woody vines and ground cover.
Rhizome:
A thickened stem (storage organ, capable of storing food), with roots growing from it, which grows horizontally below or on the soil surface. New growth then emerges from different points of the rhizome. Examples Bearded Irises, Calla Lily and some lawn grasses are rhizome plants.
Runner:
A slender creeping or, trailing stem which produces small plants along the length wherever its leaf and bud parts come in contact with the soil. These nodes and root tips are called stolons. The new plant can be severed from the parent after it has developed sufficient roots. A strawberry plant is an example of a plant that develops runners.
Erosion:
The washing away or removal of soil created by wind, water or man.
Mulching or planting cover crops after the last harvest helps to prevent wintertime erosion.
Fungicide:
A chemical used to
protect against,
inhibit, or kill
plant diseases caused by fungi.
Fungus:
A primitive form of plant life known to houseplant growers as the most
common cause of infectious disease
such as powdery mildew and sooty mold.
Weed:
Any plant (usually unattractive) growing out of place where it’s unwanted or interferes with desirable plants in the landscape. Generally weed seeds spread by winds. But seeds can also spread through domestic and commercial bulk or bags of manure, potting soil etc., and through transplants from neighbor’s yards and nursery plants.
Humus:
An organic substance resulting from the breakdown of plant material occurring naturally in soil or in the production of compost.
Humus is rich in plant nutrients and is very retentive of water when added to soil.
Humus is extremely important to the fertility of soils in both a physical and chemical sense.
Intercrop:
A crop which is grown with another crop but matures at a different rate.
Crown:
The plant crown is where the stem meets the roots. Most crowns are planted at soil level or a little above ground level. Burying the crown below the soil can lead to rot and eventually kill the plant.
