Aerate: Aerate means to loosen or perforate the soil to allow air, water, and nutrients to better reach plant roots.

Annuals: Plants that complete their life cycle within one growing season.

Aphids: Small, soft-bodied insects that can damage plants by feeding on sap.

Barefoot: Barefoot typically refers to walking or working in the garden without wearing shoes or protective footwear, allowing direct contact between the feet and the soil. It’s an ancient practice that carries deep significance across diverse cultures worldwide.

Biennial: Plants with a two-year life cycle, typically flowering and producing seeds in the second year.

Clean Cut: Using sharp scissors or pruners to harvest fruits, vegetables, or flowers cleanly without causing damage to the remaining plant.

Cold Frame: A cold frame is a low, enclosed structure with a transparent top, usually made of glass or plastic. It is used to protect plants from cold weather and extend the growing season by providing a sheltered environment that captures and retains solar heat.

Companion Planting: Planting different crops together to enhance growth, repel pests, or improve soil fertility.

Compost: Decayed organic matter used as a fertiliser and soil conditioner.

Deadheading: Deadheading refers to the practice of removing spent or faded flowers from a plant. This process is done to encourage further blooming, prevent the plant from producing seeds, and promote a neater appearance. Deadheading redirects the plant's energy from seed production to new growth and flower development.

Deciduous: Deciduous refers to plants that shed their leaves annually as part of their natural life cycle. Deciduous trees, shrubs, and plants typically lose their leaves in the fall, and they enter a dormant state during the winter months before regrowing new leaves in the spring.

Deep Watering: Providing water to penetrate deeply into the soil, encouraging deep root growth.

Direct Sunlight: Direct sunlight refers to sunlight that reaches a particular area without any obstruction or shading. A location is considered to receive direct sunlight when it is exposed to the full intensity of the sun's rays.

Drip Irrigation: A method of watering plants by delivering water directly to the base of each plant through a network of tubes or pipes.

Drought Stress: The negative impact on plants due to prolonged periods of insufficient water.

Drought Tolerant: Plants that can withstand extended periods of low water availability.

Fertiliser: A substance added to soil or plants to provide essential nutrients for growth.

Foliar Watering: Applying water directly to the leaves of plants, often done with a fine mist.

Full Sun: Plants that require at least 6 hours of direct sunlight daily for optimal growth.

Germinate: To germinate refers to the process by which a seed begins to sprout and develop into a new plant. This process involves the absorption of water, swelling of the seed, and the emergence of the embryo or seedling from the seed coat.

Grafting: Joining a part of one plant (the scion) with another (the rootstock) to create a new plant with desirable traits.

Graywater: Water from household activities (e.g., washing dishes) that can be reused for watering plants.

Half-Hardy: Half-Hardy refers to plants that are somewhat tolerant of cool temperatures but are not fully able to withstand frost or prolonged exposure to cold conditions. Half-hardy plants are typically more cold-sensitive than hardy ones.

Hardy: Hardy refers to plants that can withstand or thrive in challenging environmental conditions, such as cold temperatures, frost, or poor soil. Hardy plants are resilient and can endure adverse weather conditions without significant damage.

Hardening Off: Hardening off refers to the gradual acclimatisation of seedlings or young plants to outdoor conditions. This process involves exposing them to natural elements like sunlight, wind, and fluctuating temperatures, which prepares them for transplanting into the garden.

Hardiness Zone: A geographic area defined by climate conditions, used to select plants suitable for a particular region.

Herbaceous: Herbaceous refers to plants that have soft, non-woody stems that die back to the ground at the end of the growing season. Herbaceous plants may include annuals, biennials, and perennials, and they typically complete their life cycle within a single growing season.

Hydration: Ensuring plants receive an adequate amount of water to maintain their health and vitality.

Indirect Sunlight: Indirect sunlight refers to the light that reaches a specific area without falling directly on it. This can occur when sunlight is filtered, scattered, or partially blocked by objects such as trees, buildings, or other structures.

Mulch: Mulch refers to a layer of material, such as wood chips, straw, leaves, or other organic or inorganic substances, that are spread over the soil surface around plants.

Native Plants: Species that naturally occur in a specific region and are adapted to the local climate and soil conditions.

Nodes: Nodes refer to specific points along a stem where leaves, branches, or buds originate. These are the areas on a plant's stem where various growth elements are attached. Nodes are crucial for understanding plant structure and growth patterns.

Organic Gardening: A method of gardening that avoids synthetic chemicals and emphasises natural and sustainable practices.

Organic Matter: Organic matter refers to any substance that comes from living organisms or their remains. This includes plant and animal residues in various stages of decomposition. Organic matter is an essential component of healthy soil and is rich in carbon compounds. It contributes to soil fertility, structure, and water retention.

Overwatering: Providing excessive water to plants. This can lead to root rot and other water-related issues.

Partial Light: Partial light refers to an amount of sunlight that falls between full sunlight and full shade. Plants requiring partial light typically thrive in conditions where they receive filtered sunlight or are exposed to sunlight for only part of the day. This could be due to factors such as the presence of light shade from nearby structures, trees, or other plants.

Perennials: Plants that live for more than two years, often coming back each year.

pH Level: A measure of soil acidity or alkalinity, affecting plant nutrient availability.

Pinching: Pinching refers to the practice of manually removing or trimming off the growing tips or terminal buds of a plant. This is done to encourage bushier growth and to control the overall shape and size of the plant. Pinching is commonly applied to herbaceous annuals, perennials, and certain types of ornamental shrubs.

Propagate: Propagate refers to the process of creating new plants from existing ones.

Pruning: Trimming or cutting back plant parts (branches, stems, or roots) to shape, control growth, or remove dead/diseased material.

Rhizomes: Rhizomes refer to horizontal, underground stems that grow horizontally beneath the soil surface. These modified plant stems can produce new shoots and roots at nodes along their length.

Root Pruning: Root pruning is a horticultural practice involving the selective removal of a plant's roots. This technique is often employed to manage and enhance the health and performance of plants, particularly those grown in containers or restricted spaces.

Root Rot: Root rot is a plant disease caused by various types of fungi, and it is characterised by the decay of a plant's roots. This condition is most associated with excessive moisture or poorly drained soil, creating an environment where fungi can thrive and attack the plant's root system.

Root Zone: The area around a plant's roots where water and nutrients are absorbed.

Runoff: Excess water that flows away from the root zone, often due to compacted soil or heavy rainfall.

Saturated Soil: Thoroughly wet soil, often to the point of excess.

Seedlings: Seedlings refer to young plants that have germinated from seeds and started to grow. Seedlings are in the early stages of development, typically characterised by delicate stems, a few leaves, and a relatively small size.

Seed Propagation: Growing plants from seeds, which are produced by the parent plant.

Self-Watering Container: A container designed with a reservoir to provide a continuous supply of water to the plant.

Soaker Hose: A porous hose that allows water to seep out slowly, providing consistent moisture along its length.

Soggy Soil: Soil that is excessively wet and muddy, leading to poor aeration and potential root problems.

Sprinkler System: An irrigation system that disperses water over a large area using a network of pipes and sprinkler heads.

Thinning: Removing excess seedlings or young plants to provide adequate spacing for optimal growth.

Topiary: Artistic trimming and shaping of plants into decorative forms.

Transplanting: Transplanting refers to the process of moving a plant from one location to another. This can involve moving a plant from a seedbed or nursery to its final growing position in the garden or transferring a mature plant to a different part of the garden.

Underwatering: Providing insufficient water to plants. This leads to stress, wilting, and potential damage.

Vegetative Propagation: Generating new plants using vegetative parts such as stems, leaves, or roots. This includes methods like cuttings, layering, and division.

Water-retaining Crystals: Hydrogel products that are added to soil to absorb and release water, helping with water retention.

Watering Schedule: A planned routine for providing water to plants, considering factors like plant type, weather, and soil conditions.

Wilting: The visible sign of a plant's water stress, causing it to droop or appear limp.

Xeriscaping: Landscaping and gardening practices designed for water conservation, often using drought-resistant plants.
