Lawn Care Course

Lesson 1 • Soil Science Essentials

Examines soil composition, texture, and structure as they relate to turf performance. Connects soil health directly to root development and nutrient availability.

Lesson 2 • Reading Environmental Conditions

Teaches identification of sunlight, temperature, and moisture patterns that affect turf. Students use environmental data to anticipate lawn stress before it occurs.

Lesson 3 • Lawn Ecosystem Overview

Introduces the lawn as an interconnected ecosystem of plants, soil organisms, and climate. Helps students recognize how each element influences overall turf quality.

Lesson 1 • Building a Soil Amendment Plan

Integrates test data into a prioritized, seasonal amendment schedule. Students produce a written plan that sequences treatments for maximum turf response.

Lesson 2 • Conducting Soil Tests

Covers proper sampling techniques, test kit use, and laboratory submission procedures. Accurate sampling is the foundation for all amendment decisions in this chapter.

Lesson 3 • Understanding Nutrient Profiles

Explains macronutrient and micronutrient roles in turf health and how deficiencies appear visually. Links nutrient data from soil tests to observable lawn symptoms.

Lesson 4 • Lime and Sulfur Applications

Teaches pH correction using lime to raise and sulfur to lower soil acidity. Students calculate application rates based on soil test results and target pH ranges.

Lesson 1 • Riding and Zero-Turn Mower Operation

Covers controls, turning techniques, and slope safety for riding and zero-turn mowers. Builds on walk-behind skills to handle larger turf areas efficiently.

Lesson 2 • Blade Maintenance and Sharpening

Explains how dull blades tear grass, increasing disease susceptibility and browning. Students sharpen and balance blades to maintain clean, precise cuts.

Lesson 3 • Mowing Height Principles

Establishes the one-third rule and species-specific height ranges for optimal turf health. Correct height selection directly reduces stress and weed pressure covered later.

Lesson 4 • Mowing Patterns and Frequency

Covers directional patterns, alternating passes, and frequency based on growth rate. Proper patterns prevent soil compaction and encourage upright blade growth.

Lesson 1 • Water Conservation Strategies

Introduces drip irrigation, soil moisture sensors, and drought-tolerant turf practices. Reduces water use while maintaining acceptable turf quality under restricted conditions.

Lesson 2 • Irrigation System Components

Identifies sprinkler heads, valves, controllers, and backflow preventers and their functions. Component knowledge enables correct installation and troubleshooting covered later.

Lesson 3 • Irrigation System Troubleshooting

Covers diagnosis of clogged heads, broken lines, valve failures, and pressure problems. Students use systematic inspection to locate and repair common irrigation faults.

Lesson 4 • Turf Water Requirements

Quantifies evapotranspiration rates and species-specific water needs across seasons. Accurate demand estimates form the basis for all scheduling decisions in this chapter.

Lesson 1 • Avoiding Fertilizer Runoff and Burn

Identifies conditions that cause fertilizer burn and nutrient runoff into waterways. Students apply buffer zones, timing rules, and watering-in practices to minimize environmental impact.

Lesson 2 • Fertilizer Types and Labels

Decodes NPK ratios, guaranteed analysis panels, and release-rate designations on fertilizer labels. Label literacy is prerequisite to every rate calculation and product selection task.

Lesson 3 • Seasonal Fertilization Scheduling

Sequences fertilizer applications to match grass growth cycles for cool- and warm-season turf. Students build a 12-month calendar that aligns nutrients with peak demand periods.

Lesson 4 • Spreader and Sprayer Operation

Covers rotary and drop spreader settings, liquid sprayer calibration, and overlap techniques. Proper equipment operation ensures uniform coverage and prevents striping or skips.

Lesson 1 • Integrated Weed Management Planning

Combines cultural, mechanical, and chemical tactics into a season-long weed management plan. Students evaluate weed pressure levels and adjust strategies based on monitoring data.

Lesson 2 • Pre-Emergent Herbicide Application

Explains how pre-emergent herbicides form a chemical barrier that prevents weed seed germination. Students time applications using soil temperature data and growth degree-day models.

Lesson 3 • Weed Classification and Biology

Categorizes weeds as broadleaf, grassy, or sedge and explains annual vs. perennial life cycles. Life-cycle knowledge determines the most effective timing and method of control.

Lesson 4 • Post-Emergent Herbicide Application

Covers selective and non-selective post-emergent herbicides, surfactants, and re-entry intervals. Students match active ingredients to target weeds while protecting desirable turf.

Lesson 1 • Integrated Pest Management Strategy

Builds a monitoring-based IPM program that uses biological, cultural, and chemical controls in sequence. Students set action thresholds and select the least-disruptive effective control method.

Lesson 2 • Fungicide Selection and Application

Covers fungicide classes, modes of action, and resistance management through rotation. Students calculate rates and apply products at the correct timing to halt disease spread.

Lesson 3 • Common Turf Insect Pests

Identifies grubs, chinch bugs, armyworms, and sod webworms through damage patterns and direct observation. Correct pest identification is essential before any insecticide is selected.

Lesson 4 • Common Turf Diseases

Identifies brown patch, dollar spot, pythium blight, and other prevalent fungal diseases by symptom. Accurate diagnosis prevents misapplication of fungicides and unnecessary turf damage.

Lesson 1 • Topdressing and Turf Leveling

Uses sand, compost, or blended topdressing to smooth surfaces and improve soil profile over time. Students calculate topdressing volumes and operate spreaders for uniform application.

Lesson 2 • High-Performance Turf Management

Applies precision fertility, growth regulators, and grooming practices used on sports and premium lawns. Students integrate all prior skills into a comprehensive management program for demanding turf.

Lesson 3 • Core Aeration and Dethatching

Covers core aeration timing, plug management, and power rake dethatching to relieve compaction. These practices improve water infiltration and fertilizer uptake established in earlier chapters.

Lesson 4 • Assessing Lawn Renovation Needs

Evaluates turf coverage, weed percentage, soil compaction, and drainage to determine renovation scope. Assessment results drive the decision between partial repair and full renovation.

Lesson 5 • Sod Installation and Establishment

Covers sod selection, grading, laying patterns, and seam management for rapid establishment. Students apply irrigation and traffic restriction protocols to ensure successful sod rooting.
