Plant Care Course

Lesson 1 • Environmental Signals and Plant Response

Describes how plants sense light, temperature, and touch and adjust growth accordingly. Links environmental awareness to proactive care decisions.

Lesson 2 • Plant Cell and Tissue Basics

Introduces cell types, organelles, and tissue systems that drive plant function. Establishes the biological vocabulary used throughout the course.

Lesson 3 • Root, Stem, and Leaf Anatomy

Examines the structure and role of each major organ. Connects anatomy to practical tasks like watering, pruning, and diagnosing stress.

Lesson 4 • Photosynthesis and Respiration

Explains how plants convert light and CO2 into energy and how respiration consumes it. Grounds decisions about light placement and fertilization.

Lesson 1 • Soil pH and Nutrient Availability

Explains the pH scale and how acidity or alkalinity locks or releases nutrients. Connects pH management to fertilization efficiency.

Lesson 2 • Drainage, Aeration, and Water Retention

Covers how pore space determines water movement and oxygen availability. Guides students in diagnosing compaction and waterlogging issues.

Lesson 3 • Soil Biology and Microbial Life

Examines bacteria, fungi, and soil fauna that cycle nutrients and support root health. Teaches practices that protect and enhance soil biology.

Lesson 4 • Container and Soilless Growing Media

Introduces peat, coir, perlite, bark, and hydroponic substrates as alternatives to field soil. Prepares students to build custom mixes for containers.

Lesson 1 • Watering Methods and Equipment

Compares overhead, bottom, drip, and misting techniques for different plant types. Matches method to plant needs, container type, and environment.

Lesson 2 • Water Quality and Treatment

Addresses how mineral content, chlorine, and pH in tap water affect plants. Guides students in treating or sourcing appropriate water.

Lesson 3 • How Plants Use Water

Explains water uptake, transport through xylem, and loss through transpiration. Establishes why water balance is central to every care decision.

Lesson 4 • Reading Plant and Soil Moisture Cues

Teaches visual, tactile, and instrument-based methods to assess moisture needs. Reduces guesswork and prevents both drought stress and root rot.

Lesson 1 • Understanding Light for Plants

Covers light intensity, spectrum, and duration and their effects on photosynthesis and flowering. Provides the basis for placement and supplemental lighting decisions.

Lesson 2 • Humidity Control Indoors

Explains relative humidity needs for tropical, desert, and temperate plants. Teaches practical methods to raise or lower humidity in any space.

Lesson 3 • Artificial and Supplemental Lighting

Compares fluorescent, LED, and HID grow lights for indoor and low-light settings. Teaches setup, distance, and duration for optimal plant response.

Lesson 4 • Air Circulation and Ventilation

Describes how airflow strengthens stems, reduces fungal risk, and regulates temperature. Guides placement of fans and vents in indoor and greenhouse settings.

Lesson 1 • Essential Macro- and Micronutrients

Identifies the 17 essential elements, their roles, and deficiency symptoms. Provides the diagnostic framework used in all subsequent fertilization decisions.

Lesson 2 • Reading and Interpreting Fertilizer Labels

Decodes NPK ratios, guaranteed analysis, and application rates on product labels. Enables accurate product selection and safe dosing.

Lesson 3 • Synthetic Fertilizers and Liquid Feeding

Explains water-soluble and granular synthetic options and their fast-acting nutrient delivery. Addresses salt buildup risks and flushing protocols.

Lesson 4 • Building a Seasonal Feeding Schedule

Integrates growth stage, season, and plant type into a structured fertilization calendar. Prevents over-feeding and nutrient lockout through planned cycling.

Lesson 1 • Propagation Methods

Teaches stem cuttings, leaf cuttings, division, layering, and seed starting. Connects each method to the plant types and conditions where it succeeds.

Lesson 2 • Repotting Procedure and Root Care

Walks through safe removal, root inspection, pruning, and replanting steps. Minimizes transplant shock and promotes rapid re-establishment.

Lesson 3 • Timing and Seasonal Pruning

Explains when to prune based on bloom time, growth cycle, and plant type. Prevents accidental removal of flower buds or stress during vulnerable periods.

Lesson 4 • Recognizing When to Repot

Identifies root-bound symptoms, soil degradation signs, and size-upgrade criteria. Builds judgment for repotting frequency across plant types.

Lesson 1 • Fungal, Bacterial, and Viral Diseases

Covers powdery mildew, root rot, leaf spot, and mosaic viruses with diagnostic criteria. Links disease conditions to environmental causes for prevention.

Lesson 2 • Common Insect Pests

Identifies aphids, spider mites, fungus gnats, mealybugs, scale, and thrips by damage pattern and appearance. Establishes accurate diagnosis before treatment.

Lesson 3 • Integrated Pest Management Principles

Introduces IPM as a tiered approach: prevention, monitoring, biological, and chemical controls. Reduces chemical dependency while maintaining effective pest suppression.

Lesson 4 • Quarantine and Prevention Protocols

Establishes routines for inspecting new plants, isolating infestations, and sanitizing tools. Protects existing collections from introduced pests and diseases.

Lesson 1 • Managing Large and Diverse Collections

Addresses grouping strategies, rotation systems, and record-keeping for multi-plant environments. Scales individual care skills to professional or large-home settings.

Lesson 2 • Seasonal Transitions and Acclimatization

Covers hardening off, indoor-to-outdoor transitions, and adjusting care as seasons shift. Prevents shock and loss during environmental changes.

Lesson 3 • Diagnosing Complex Plant Problems

Teaches a systematic elimination process for overlapping symptoms from multiple causes. Builds clinical reasoning skills that go beyond single-factor diagnosis.

Lesson 4 • Reviving Neglected and Stressed Plants

Provides triage protocols for severely wilted, root-rotted, or pest-damaged plants. Builds confidence in rescuing plants that appear beyond recovery.

Lesson 5 • Continuous Learning and Skill Development

Encourages observation habits, journaling, and community engagement to deepen expertise. Positions students as lifelong learners who refine skills through practice.
