  • SOILS REVIEW QUESTIONS
  • Plant Types Seedling Monocot – single seed leaf
  • Grasses, small grains (corn, wheat, oats, barley, etc.)
  • Dicot – two seed leaves
  • Different requirements and care Monocots – high N use Dicots – lower N use Herbicides developed to affect one and not the other Spray grass out of garden Spray weeds out of lawn
  • Biennials Vegetative growth 1 st year, seed development 2 nd year Perennials May establish new plants from roots, stems, seeds, etc.
  • Stolon Adventitious roots
  • Rhizome Adventitious roots
  • Tuber Short, underground. Fleshy Bulb Short, flattened, many leaves. underground Corm Short, solid, vertical, enlarged, underground
  • Tap Growing mostly downward.
  • Stamen – male Pistil – female
  • Moves with water, excess watering washes out of root zone &amp; contaminates water table.
