Learning objectives
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
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
Tools

  • Soil-working tools

  • Watering equipment

  • Rakes

  • Fertilizing Equipment


Power 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
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
Irrigation

  • Sprinklers

  • Hand-watering

  • Drip or trickle irrigation


Fertilizing
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
Cultural Weed Control

  • Hand-pulling

  • Cultivating with a hoe

  • Weed barriers

  • Mulching

  • Solarization


Chemical weed control
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
Mulches

  • Organic

    • Plant-derived

    • Should be weed-and pesticide-free

    • Shredded bark, pine straw, etc

  • Inorganic

    • Rock

    • Marble chips

    • Recycled tires


Common landscape problems
Common Landscape Problems

  • Suckers

  • Mower Blight

  • Crossing Branches

  • Stem Girdling Roots


Why prune
Why Prune?

  • Size Control

  • Health Improvement

  • Appearance


Review questions
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?
