  1. Landscape Management Practices Mulching, Watering, Staking, Fertilization, Weed Control Presented by Dr. Teri Hamlin Georgia Department of Education Georgia Agricultural Education Curriculum Office July 2001

  2. MulchA tree’s best friend • Insulates soil • Retains moisture • Keeps weeds out • Prevents soil compaction • Reduces lawn mower / weedeater damage • Adds an aesthetic touch

  3. Mulch

  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. Type of Mulch • Bark • Pine Straw • Grass Clippings • Leaves • Rock • Synthetic Materials

  6. Ground Cloth under Mulch ???

  7. IrrigationHow much ? How often? • During establishment • Minimum of 1” of water per week • Water between 9 p.m. - 9 a.m.

  8. Types of Irrigation • Sprinkler • Micro Sprinkler • Drip Irrigation

  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. Drip Irrigation

  12. XeriscapeWater Management Practices

  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. Types of Staking • Support weak trunk • Root ball anchorage

  15. Staking

  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. 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. 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. Fertilizer • Nitrogen • Phosphorus • Potassium Landscape plants needs should be based on Soil Sample

  20. Forms of Slow-release Nitrogen Ammoniacal nitrogen IBDU (Isobutylene diurea) Sulfur-coated urea Ureaformaldehyde

  21. General Recommendation

  22. Types of Fertilizer • Sources: • Inorganic • Organic • Formation: • Dry / Granular • Liquid • Slow-release

  23. How to Apply Fertilizer

  24. Fertilizer Burn

  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. 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)
