Quick Reference

Soil Health

The overall condition of soil as a living ecosystem, including its physical structure, chemical composition (pH, nutrients), and biological activity (microorganisms, earthworms). Healthy soil is the foundation of productive gardening.

Hardiness Zones

Geographic regions defined by average annual minimum winter temperatures, used to determine which plants are most likely to thrive in a given location. The USDA Plant Hardiness Zone Map divides North America into 13 zones.

Companion Planting

The practice of growing certain plants near each other to provide mutual benefits such as pest deterrence, pollination enhancement, nutrient sharing, or physical support.

Composting

The controlled biological decomposition of organic materials such as kitchen scraps, yard waste, and plant matter into humus, a nutrient-rich soil amendment that improves soil structure, water retention, and fertility.

Crop Rotation

The practice of growing different types of crops in the same area across sequential seasons to prevent soil nutrient depletion, reduce pest and disease buildup, and improve soil structure.

Seed Starting and Germination

The process of initiating plant growth from seeds under controlled conditions, typically indoors before the outdoor growing season begins. Germination requires the right combination of moisture, temperature, oxygen, and sometimes light.

Integrated Pest Management (IPM)

A sustainable approach to managing garden pests that combines biological controls, cultural practices, physical barriers, and targeted chemical treatments as a last resort, minimizing environmental impact while protecting plants.

Raised Bed Gardening

A method of growing plants in soil that is elevated above the surrounding ground level, typically contained within a frame made of wood, stone, or metal. Raised beds offer improved drainage, better soil control, reduced compaction, and easier accessibility.

Photosynthesis and Light Requirements

The process by which plants convert sunlight, water, and carbon dioxide into glucose and oxygen. Different plants have varying light requirements classified as full sun (6+ hours direct light), partial shade (3-6 hours), or full shade (less than 3 hours).

Mulching

The practice of covering the soil surface around plants with organic or inorganic materials to conserve moisture, suppress weeds, regulate soil temperature, and gradually add nutrients as organic mulches decompose.

Key Terms at a Glance

Amendment:Any material added to soil to improve its physical or chemical properties, such as compost, lime, peat moss, or perlite.

Annual:A plant that completes its entire life cycle, from germination to seed production, in a single growing season.

Bolting:The premature production of flowers and seeds by a vegetable plant, typically triggered by heat or photoperiod changes, rendering the crop bitter or unusable.

Companion Planting:Growing specific plant combinations in proximity for mutual benefits such as pest deterrence, improved pollination, or nutrient sharing.

Compost:Decomposed organic matter used as a soil amendment, created through the controlled breakdown of kitchen scraps, yard waste, and other biodegradable materials.

Cover Crop:A crop planted primarily to protect and enrich soil rather than for harvest, often grown during off-seasons to prevent erosion and fix nitrogen.

Crop Rotation:The systematic practice of growing different plant families in the same location across successive seasons to maintain soil health and break pest cycles.

Deadheading:The removal of spent flowers from a plant to encourage continued blooming, redirect energy to growth, and maintain a tidy appearance.

Drip Irrigation:A water-efficient irrigation system that delivers water slowly and directly to plant root zones through tubes and emitters, reducing evaporation and runoff.

Fertilizer:A substance containing essential plant nutrients (primarily nitrogen, phosphorus, and potassium) applied to soil or plants to promote growth.

Germination:The process by which a seed absorbs water, activates enzymes, and begins to grow into a seedling, requiring specific conditions of moisture, temperature, and sometimes light.

Hardening Off:The gradual process of acclimating indoor-grown seedlings to outdoor environmental conditions before permanent transplanting.

Hardiness Zone:A geographically defined area based on average minimum winter temperature, used to indicate which plants are likely to survive winter in a given region.

Humus:The dark, stable, organic component of soil formed by the decomposition of plant and animal matter, essential for soil structure and nutrient retention.

Integrated Pest Management (IPM):An ecosystem-based pest control strategy that combines biological, cultural, physical, and chemical methods with emphasis on long-term prevention and minimal environmental impact.
