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 • Usually just before or during active plant growth • Spring most common • Rate • Trees: 6 lbs actual N per 1,000 sqft • Shrubs: 2-4 lbs actual N per 100 sqft • Groundcovers: 2-4 lbs actual N per 1,000 sqft
Cultural Weed Control • Hand-pulling • Cultivating with a hoe • Weed barriers • Mulching • Solarization
Chemical Weed Control • Pre-emergence • Trifluralin • Oryzalin • Only kill germinating seedlings, not established plants • Post-emergence • 2,4-D (dandelion control in lawns) • Glyphosate(non-selective, spot-treatment) • Kill weeds on contact • Bio-herbicides • Wheat or corn gluten meal
Mulches • Organic • Plant-derived • Should be weed-and pesticide-free • Shredded bark, pine straw, etc • Inorganic • Rock • Marble chips • Recycled tires
Common Landscape Problems • Suckers • Mower Blight • Crossing Branches • Stem Girdling Roots
Why Prune? • Size Control • Health Improvement • Appearance
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?
