Tree installation and establishment ppt
- 1. Tree Installation and Establishment
- 2. Select Tree Species to Fit Site •Function or use •Adaptability •Soil characteristics •Pest susceptibility •Maintenance requirements
- 3. Nursery Stock Types Container 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 1 Spiraling and other 2 deformities can cause 3 girdling roots, tree instability, and other future problems!

If so, measure trunk caliper 12 inches above ground. Source: American Standard for Nursery Stock ANSI 60.1, and Florida Grades and Standards for Nursery Stock
- 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

- 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

- 17. Other Tree Growing Systems RPM SYSTEM Forrest Keeling Nursery, Elsberry, MO
- 18. Fibrous Roots RPM roots Conventional seedling Fibrous RPM and other systems container roots promote many branched, 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. Tree Planting
- 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
- 26. Check Rootball or Container for Excess Soil over Root System
- 27. Remove soil from ball top if needed
- 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
- 39. Watering From Hydrant Truck Mounted Tank Apply equivalent of 1” rain per week Watering Bag
- 40. Re-mulching No “volcano” mulching Replace organic mulch every 1-2 years, 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 Be Required
- 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 technique for site •Follow-up with good maintenance
