2.  Describe the factors involved in selecting appropriate landscape plants.  Explain the general guidelines for purchasing healthy landscape plants.  Compare and contrast the planting procedures for balled-and-burlapped vs. container-grown plants.  Diagram how to stake a newly planted tree.

3.  Trees ◦ Size  Large (>45 ft.)  Medium (30-45 ft.)  Small (10-30 ft.)  Shade  Rooting characteristics ◦ Invasive ◦ Surface roots  Shrubs

4. Small-space trees  Amur maple  Japanese maple  Eastern redbud  Kousa dogwood  Kwanzan cherry  Japanese tree lilac

5. Trees with invasive roots:  Silver maple  Willow  Poplar  Alder  Sweet gum

6.  Local garden centers ◦ Sell plants grown by wholesale nurseries  Retail nurseries ◦ Grow some of the plants they sell, and may offer landscape design and installation services  Mail-order catalogs ◦ May offer plants not available locally

7.  Tree health  Tree size  Tree type Root system, root ball, or container spread should be 10 to 12 inches for every inch of stem diameter.

8.  Inexpensive and light weight  Best when young  Should have a caliper of <2 inches  Plant when dormant before buds begin to swell  Soak roots in water for up to 24 hours before planting.

9.  Both fine and coarse roots are included ◦ Less transplant shock  Handle root ball gently to avoid disturbing root contact with soil  Watch for buried root collars: ◦ Avoid buying trees with more than 4 inches of soil over the root collar.

10.  Round pots can cause circling roots ◦ cut or straighten at time of planting.  Should be well rooted but not root-bound.  Avoid trees grown bare- root but recently potted for sale.

12.  Keep trees and shrubs shaded, cool, and moist before planting.  Remove all labels/wires from the stem.  Point tops of plants away from afternoon sun if they must be stored in the open.

14.  Remove wire baskets, pots, etc.  Cut away the burlap from top and sides of root ball

16.  Bare-root trees need staking to anchor.  Staking should allow for trunk flexing in the wind.  Trees allowed to move with the wind develop reaction wood.  Remove after 1-2 seasons.

17.  Deep, thorough watering is key.  Sprinkler systems for lawn offer only shallow watering.  Place a hose at the tree base for 15 minutes.  Mulch around the base to prevent evaporation.

18.  Plant shallow using backfill soil mounded to cover root system  Install subsurface tile drains to carry water away from roots

19.  The most important aspect of landscape tree selection is tree ______________.  A common problem with balled-and- burlapped trees is buried root __________.  Bare-root trees should be planted in which season?  The planting hole should be _________ times ___________ than the root ball.  T or F –All newly planted trees should be staked.
