Tree Placement in the Landscape
A program of Sedgwick County Extension Master Gardeners
K-STATEResearch & Extension
Benefits of trees
• Increased property values (13-21%)• Wind Protection• Winter Heating• Summer Cooling• Filters dust• Sound buffer• Produces oxygen• Reduces wind and water erosion of soil• Wildlife habitat
K-STATEResearch & Extension
Right Tree, Right Place, Right Way
• How to plant for long term survival– Selecting Trees according to
• Soil types
• Drought/moisture tolerance
• Height vs. utility lines
• Spread and distance from structures
• Spacing
K-STATEResearch & Extension
Average Tree Life
• Forest tree – longest potential life span• City landscape tree – 32 years (American Forests, 1989)
• Downtown trees – 7-10 years (American Forests, 1989)

Placement of Trees
• Enframes house to make it look larger
• Background trees give house “sense of place”
• Screen poor views
• Accent features
• Soften harsh lines

Large Trees 40’ +
K-STATEResearch & Extension
Spacing Between Trees
(Suggested minimum spacing)
Small Trees 15’
Medium Trees 30’
Large Trees 40’
K-STATEResearch & Extension
Rooting Distance
• 2 - 2 ½ times spread of dripline
K-STATEResearch & Extension
Minimum Distance from Sidewalk/Driveways
• Small trees 2’• Medium 4’• Large 6’
Roots were cut when walk was replaced. Will the tree survive?

Utility Companies have the right to:
• Remove Trees
• Prune as needed
In Easements
• Don’t Plant there
• Use small trees
• Use temporary trees

Tree Tips
Sedgwick County Extension Master Tree Gardeners
K-STATEResearch & Extension
Tips For Rapid Growing Trees
1. Plant at Proper Depth
Don’t plant too deep -
Plant at same depth or slightly higher than grown in the nursery
Root flare should be slightly below the surface
K-STATEResearch & Extension
Tips For Rapid Growing Trees
2. Retain Lower LimbsFood reserves are produced through photosynthesis of sun reachingthe leaves.
• More leaves = more growth• Always maintain
2/3 branches1/3 trunk
• Leaves shade the trunk & feed the trunk
K-STATEResearch & Extension
Composts/Leaf Mulches
• May be worked into annual beds or as a surface mulch
• Increase Organic Matter Content
• Improve drainage
• Reduce root diseases
K-STATEResearch & Extension
Tips For Rapid Growing Trees
4. Water as Needed
Maintain moisture in the root zone (Root zone = twice branch spread)
K-STATEResearch & Extension
Tips For Rapid Growing Trees
5. Control Grass and Weeds
Grass (especially fescue and brome slow the growth of young trees)
K-STATEResearch & Extension
Mulching Trees
• 2-3 inches deep
• 3 ft from trunk to drip line
• Keep 3-6 inches from trunk
K-STATEResearch & Extension
Tips For Rapid Growing Trees
6. Fertilize in November –spring
Only need to fertilize
slow growing trees
(Fertilizer burn)

7. Prevent Weed Trimmer Injury
use mulches

Tips For Rapid Growing Trees
8. Protect bark on thin bark trees in winter
White wrap is preferred – reflects light and doesn’t heat

Tips For Rapid Growing Trees
9. Stabilize root system the first year with staking lower in the tree

Protect Water Quality
Largest Pollutant in Rivers
• Sediment
• Other potential pollutants –– Fecal bacteria– Nitrogen– Phosphorus– Pesticides
K-STATEResearch & Extension
Protecting Water Quality• Prevent erosion
• Tree planting along water flow banks
• Unmowed grasses filter
• Don’t fertilize near water
• Apply Phosphorus according to soil test needs
• Sweep/blow fertilizers from streets & walks
