Each component should be considered when making planting choices.

  • Life Cycle: Typical lifespan of the type of plant. Annual plants germinate, bloom, set seed and die all in one year. Biennial plants have a life cycle of two years, so they germinate and grow one year, bloom and die the following. Everything which lasts longer than two years is perennial.
  • Planting Season: The best season to plant and get a successful stand. This is a typical seasonal guide only, check soil temperatures to best correlate to your region.
  • Optimum Temp. for Germ. (F): The minimum soil temperature required for seeds to germinate and grow.
  • Planting Depth (Inches): How deep to plant seed for proper germination. Common problems with planting seeds at the wrong depth include failed germination and weak seedlings.
  • Planting Rate: The most common planting rates for a given area for a full planting rate. This rate can change when species are planted in a mix such as cover crops.
  • Appox. Seeds/LB: The typical number of seeds per pound for a given species. This number can vary with varietal differences.
