  • Observe shading patterns What is a potential hazard? Black WAlnut tree Lead paint- old building site What do you think of this site? shade, low area
  • First and foremost, get a soil test: pH, P, K, lime, Mg Should be done in fall if possible to apply lime in fall. $6 kit from Extension office, results mailed to homeowner Need a representative sample: several cores at same depth: stratification of soil especially top 1 inch. pH is probably single most important factor. N is not tested for because N is rapidly transformed in soils
  • nutrients according to soil test types of organic matter: compost, manure
  • How do you decide if you plant seeds or transplants? Days to harvest
  • Critical watering period chart in manual example melons- flowering fruit development
  • Grow Your Own Food A

    1. 1. Grow Your Own Food? Of Course You Can! (Part 1) Lee Young, Extension Educator, and Deb Andrus, Master Gardener Site Soils Planting Watering Techniques
    2. 2. in-ground vs. containers
    3. 3. GARDEN SITE NEEDS <ul><li>Sunlight, 8-10 hours </li></ul><ul><li>Level land </li></ul><ul><li>Good drainage </li></ul><ul><li>Avoid low areas </li></ul><ul><li>Avoid windy sites </li></ul><ul><li>Near water source </li></ul><ul><li>Distance from trees </li></ul><ul><li>Protect from wildlife </li></ul>
    4. 4. Soil: a mixture of weathered minerals and decaying organic matter , covering the earth in a thin layer. When combined with air and water , soil provides mechanical support and nutrients for plants.
    5. 5. Soil Pie Solids 50 % Pore Space 50 % Minerals 45 % Sand, silt, clay Air 25 % Water 25 % O.M.
    6. 6. Organic Matter Matters! <ul><li>Biological activity=healthy soil </li></ul><ul><li>Water and nutrient retention and release </li></ul><ul><li>Buffers pH </li></ul><ul><li>Improved soil tilth=better root growth </li></ul>
    7. 7. Soil texture <ul><li>Relative proportion of: </li></ul><ul><ul><li>Sand = large particles </li></ul></ul><ul><ul><li>Silt = medium particles </li></ul></ul><ul><ul><li>Clay = very, very small particles </li></ul></ul>Which type do we have?
