Glossary of Terms

2.01.2011

When I first started learning about gardening, it seemed like there were a lot of terms being thrown around that I didn't know.  Here, I'll keep a working list of terms I use throughout the blog that you may not know. If you have any other terms you'd like me to add, please feel free to let me know!

A

Annuals:  An annual plant is a plant that germinates, fruits, flowers and dies in one growing season.

Hardening Off:  The process of gradually introducing seedlings sown indoors to sunlight and outside weather.

Hardiness Zone: is a geographically defined area in which a specific category of plant life is capable of growing, as defined by climatic conditions, including its ability to withstand the minimum temperatures of the zone.
 

Hardiness:  describes the  plant's ability to survive diverse growing conditions.  It is usually limited to climactic adversity, and thus a plant's ability to tolerate cold, heat, drought, wind, flooding or even disease.  The hardiness of plants is often a result of their natural growing zone or hardiness zoneHardiness of a plant is usually divided into three categories: tender, half-hardy, and hardy. Tender plants are those killed by freezing temperatures, while hardy plants survive freezing—at least down to certain temperatures, depending on the plant.

Heat Zone:  The 12 zones of the map indicate the average number of days each year that a given region experiences "heat days"-temperatures over 86°F; the point at which the plant begins to suffer physiological damage.  Zone 1 consists of areas with less than 1 heat day per year, and Zone 12 areas experience more than 210 heat days

Sow or Sowing: The process of planting seeds. 

T
Transplant:  or replanting is the technique of moving a plant from one location to another. Most often this takes the form of starting a plant from seed in optimal conditions, such as in a greenhouse or protected nursery bed then replanting it in another, usually outdoor, growing location.

True Leaves:  When seedlings sprout, often there are two-sets of leaves that form first. They look almost four-leaf clover like. A few days later a third single leaf will emerge that doesn’t look like the first two. That’s the first true leaf.  Once four true leaves emerge that is usually when you can start fertilizing, transplanting, thinning or doing whatever else you are going to do.
