Landscape management

  1. 1. Presented by Dr. Teri Hamlin Georgia Department of Education Georgia Agricultural Education Curriculum Office July 2001 Landscape Management Practices Mulching, Watering, Staking, Fertilization, Weed Control
  2. 2. Mulch A tree’s best friend • Insulates soil • Retains moisture • Keeps weeds out • Prevents soil compaction • Reduces lawn mower / weedeater damage • Adds an aesthetic touch
  3. 3. Mulch
  4. 4. Mulch • Max depth of 2-4” • Do not touch the trunk • Mulch too deep can lead to – trunk & crown rot – poor root ball aeration
  5. 5. Type of Mulch • Bark • Pine Straw • Grass Clippings • Leaves • Rock • Synthetic Materials
  6. 6. Ground Cloth under Mulch ???
  7. 7. Irrigation How much ? How often? • During establishment – Minimum of 1” of water per week • Water between 9 p.m. - 9 a.m.
  8. 8. Types of Irrigation • Sprinkler • Micro Sprinkler • Drip Irrigation
  9. 9. Drip Irrigation Uses 30-50% less water Efficient and effective application Fewer pest problems Fewer weeds No wind effects Easily automated Economic to install
  10. 10. Drip Irrigation
  11. 11. Time Clock
  12. 12. Xeriscape Water Management Practices
  13. 13. Staking • Good - quality trees do not require staking • When to stake: – Windy Location – Top Heavy – Plants 8’ or taller – Weak Trunks – Small Root Ball – Evergreens
  14. 14. Types of Staking • Support weak trunk Root ball anchorage
  15. 15. Staking
  16. 16. Staking • Rubber straps are nicely suited for attaching stakes to trunks • Wire threaded through hose can girdle plant if left to long • Never leave a plant staked for more than one growing season
  17. 17. Trunk Protection • Little protection against insect & disease • Some sun scald protection for thin bark plants • Uneven wraps w/exposed bark = temp difference in trunk tissue • Products : – Paper Wrap – Burlap – Plastic – White Latex Paint
  18. 18. Trunk Wraps • If used, wrap from the bottom of the tree toward the top overlapping material • Use electrical tape or flexible adhesive versus string
  19. 19. Fertilizer • Nitrogen • Phosphorus • Potassium Landscape plants needs should be based on Soil Sample
  20. 20. Forms of Slow-release Nitrogen Ammoniacal nitrogen IBDU (Isobutylene diurea) Sulfur-coated urea Ureaformaldehyde
  21. 21. General Recommendation
  22. 22. Types of Fertilizer • Sources: – Inorganic – Organic • Formation: – Dry / Granular – Liquid – Slow-release
  23. 23. How to Apply Fertilizer
  24. 24. Fertilizer Burn
  25. 25. When to Fertilize • Main Meal – Slow Release ( 1 time per year) – General Purpose (2-3 x per growing season) • Dessert – During active growth (Spring-Summer) – Liquid • Soil drench • Foliage Spray
  26. 26. Weed Management • Mechanical • Chemical – Pre-emergent Herbicide • Surflan, Treflan, Ronstar, Balan – Post-emergent Herbicide • Selective – Kills grasses in shrubs & flowers (Poast) – Kills broadleaf weeds in lawns (MSMA, Trimec) • Non-Selective (Round up)
