Transcript

  • 1. Tree Installation andEstablishment
  • 2. Select Tree Species to Fit Site •Function or use •Adaptability •Soil characteristics •Pest susceptibility •Maintenance requirements
  • 3. Nursery Stock TypesContainer Balled grown and burlapped Grow Bare Potted bags root
  • 4. Container Grown Trees Advantages • Ease of handling • Extends planting time • Lightweight soil • Many species, sizes available • Normally under 2” caliper Disadvantages • May distort roots
  • 5. Distorted Roots 1Spiraling and other 2deformities can cause 3girdling roots, treeinstability, and otherfuture problems!
  • 6. Standards for Container Grown Trees Minimum Minimum tree Minimum tree Trunk caliper Maximum tree container size height on height on slower (inches)1 height (gallons) standard trees grown trees 1 5 6 5 10 2 20 10 8 14 3 45 12 9.5 16 4 95 14 10.5 18 5 951 Trunk diameter (caliper) is measured 6 inches from the ground unlesstrunk is more than 4 inches caliper. If so, measure trunk caliper 12 inchesabove ground. Source: American Standard for Nursery Stock ANSI 60.1,and Florida Grades and Standards for Nursery Stock
  • 7. Small Container Standards
  • 8. Balled and Burlapped Trees Advantages • Traditional method • No bound roots • Over 2” caliper Disadvantages • Heavy • Limited time for lifting • 90%+ roots lost • Establishment time • May have extra soil over roots
  • 9. Tree Ball Methods
  • 10. High/Low Profile Baskets

  • 12. Tree Ball Standards---1-1/4 Inch Caliper
  • 13. Tree Ball Standards---2 Inch Caliper
  • 14. Tree Ball Standards---3 Inch Caliper
  • 15. Bare Root Trees Advantages • Reduced weight • Less costly • Permits full examination of roots Disadvantages • Limited planting time • Specialized handling • Usually wholesale only
  • 16.

  • 17. Other Tree Growing Systems RPM SYSTEM Forrest Keeling Nursery, Elsberry, MO
  • 18. Fibrous Roots RPM roots Conventional seedling FibrousRPM and other systems container rootspromote manybranched, fibrous roots
  • 19. Desirable Tree Characteristics • Pleasing proportions 1-1/2 • Vigorous growth Inch Caliper, • Bright green cambium B&B • Evenly spaced branches • No narrow branch angles • Straight trunk • No wounds • Well formed roots, kept moist
  • 20. Protect Trees During Transport
  • 21. TreePlanting
  • 22. Use Correct Technique • Tree planting knowledge is not innate • More than one way to plant
  • 23. What’s Wrong With This Picture? • Hole Too Small • Roots Too Deep
  • 24. Outmoded Planting Practices • Routine stakes, trunk wrap, soil berm • Narrow hole • Underdug hole • Soil amendments • Cut back branches
  • 25. Recommended Planting Technique
  • 26. Check Rootball or Container for Excess Soilover Root System
  • 27. Remove soil from ball top if needed
  • 28. Recommended Planting Technique
  • 29. Recommended Planting Technique
  • 30. AFA Tree Planting Method
  • 31. Planted Tree, No Stakes
  • 32. Standard Planting with Stakes • For windy locations or small root system • To protect stem • Use non-abrasive ties, low on stem • Allow tree to flex • Remove ties, stakes ASAP
  • 33. Optional Berm Planting • For compacted or shallow soils • May be used in lieu of standard planting • Stakes, ties, optional
  • 34. Root Development in Berm
  • 35. Subsurface Planting Drain • For poorly drained soils • Run drain to daylight
  • 36. Low Berm After Planting Powell Gardens
  • 37. Extra Large Berm With Groundcover Powell Gardens
  • 38. PlantingAftercare
  • 39. Watering From HydrantTruck Mounted TankApply equivalent of 1” rain perweek Watering Bag
  • 40. Re-mulching No “volcano” mulchingReplace organicmulch every 1-2years, 2-3” deep
  • 41. Remove Stakes and Wrap •Stakes no longer than one year •Remove wrap before first growing season
  • 42. Additional Trunk Protection May BeRequired
  • 43. Prune planted trees minimally Begin routine pruning 3 years after planting
  • 44. •Select trees to fit site•Purchase vigorous trees with well-formed branches and roots•Determine correct planting techniquefor site•Follow-up with good maintenance
