Landscape Maintenance
Learning Objectives List the tools required for general landscape
maintenance.
Describe the advantages and disadvantages of the different methods of irrigation.
Describe four mulches suitable for use in landscapes.
Recognize common landscape plant problems, such as crossing branches, girdling roots, and suckering.
List the three main purposes of pruning.
Low Maintenance Landscapes
Features: Groundcover areas instead of lawns Mulches around trees and shrubs Automatic irrigation system Low-maintenance plants Flowering shrubs rather than annual and
perennial flowers Plants that are disease-and insect-resistant Plant adapted to the local climate
Tools Soil-working tools
Watering equipment
Rakes
Fertilizing Equipment
Power Equipment Hedge trimmer –good for long sections of formal hedge
Power blower–blowing grass and leaves off paved areas
String trimmer –trim grass beside paved areas
Edger–maintains a clean line between turf and non-turf areas
Chain Saw –removal of large trees and shrubs
Power pruner –for high branches
Safety around Power Equipment
Eye protection
Remove sticks, stones, and other debris
Keep people and pets 50 ft. away
Do not use lawn edgers in graveled areas
Hearing protection around gas-powered (2-stroke) engines
Safety footwear
Irrigation Sprinklers
Hand-watering
Drip or trickle irrigation
Fertilizing Timing
o Usually just before or during active plant growtho Spring most common
Rateo Trees: 6 lbs actual N per 1,000 sq fto Shrubs: 2-4 lbs actual N per 100 sq fto Groundcovers: 2-4 lbs actual N per 1,000 sq ft
Cultural Weed Control Hand-pulling
Cultivating with a hoe
Weed barriers
Mulching
Solarization
Chemical Weed Control Pre-emergence
o Trifluralino Oryzalino Only kill germinating seedlings, not established plants
Post-emergenceo 2,4-D (dandelion control in lawns)o Glyphosate(non-selective, spot-treatment)o Kill weeds on contact
Bio-herbicideso Wheat or corn gluten meal
Mulches Organic
o Plant-derivedo Should be weed-and pesticide-freeo Shredded bark, pine straw, etc
Inorganico Rocko Marble chipso Recycled tires
Common Landscape Problems
Suckers
Mower Blight
Crossing Branches
Stem Girdling Roots
Why Prune? Size Control
Health Improvement

Review Questions Name three examples of personal protective gear to
be worn around power equipment.
A benefit of drip irrigation is that water is applied directly to roots of desired plants, minimizing growth of __________.
Describe one major difference between organic and inorganic mulches.
Mulching around landscape plants can protect trees from which common landscape problem?
