Garden Glossary Terms

What is BSP Thread?

BSP (British Standard Pipe) is the standard screw thread used on UK garden hose fittings, taps and connectors. Most outdoor taps and hose pipe fittings use 3/4" BSP, which is why hoses and adaptors bought in the UK generally fit straight onto garden taps without extra adaptors, unlike some imported garden equipment.

What is Polycarbonate (Greenhouses)?

Polycarbonate is a lightweight, virtually shatterproof plastic glazing material used as an alternative to glass in many UK greenhouses. Twin-wall or multi-wall polycarbonate panels trap air between layers, giving better insulation than single-pane glass, and its impact resistance makes it a popular choice for gardens with children or in hail-prone areas.

What Do PSI and Flow Rate Mean for Garden Irrigation?

PSI (pounds per square inch) measures the water pressure feeding a hose or sprinkler system, while flow rate (usually litres per minute) measures the volume delivered. UK mains pressure varies by property, so drip irrigation kits and multi-sprinkler setups often need a pressure regulator to avoid running too fast or too weak for even watering.

What Does Cutting Width Mean on a Lawn Mower?

Cutting width is the width of grass cut in a single pass, typically 30-32cm for small electric mowers up to 50cm+ for larger petrol models. A wider cutting width covers a lawn in fewer passes, saving time on bigger gardens, but wider mowers are heavier and less manoeuvrable around borders, beds and tight corners.

What is Cordless?

When used for power tools like hedge trimmers and vacuum cleaners, ‘cordless’ describes a product that operates without needing to be plugged into a mains electricity supply. This means the tool is powered by a rechargeable battery pack. For a UK shopper, it indicates greater portability and freedom of movement; you aren't tethered to an outlet. However, cordless tools tend to be heavier than their corded counterparts due to the battery weight and require regular charging. Battery life also varies greatly between models – consider how long you’ll use the tool before needing a recharge.

What is Resin?

Resin, when used to describe a home and garden product, typically refers to plastic materials produced through a chemical process involving polymers – often PVC or polyethylene. It's frequently employed for outdoor items like storage boxes and decorative features due to its relative weather resistance. Resin products are generally lighter than traditional materials such as cast iron or wood, though this can vary depending on the specific formulation. They require minimal maintenance compared to timber but may be susceptible to UV damage over time, potentially leading to fading or cracking if exposed to prolonged direct sunlight; careful consideration of placement and occasional cleaning is advisable.

What is Small gardens?

‘Small gardens’ refers to garden spaces typically under 100 square metres – roughly equivalent to a typical suburban back yard or front garden. When used in product specifications for home & garden items like lawn mowers or sheds, it indicates the design and features are geared towards smaller areas. This often means lighter weight machinery, compact storage solutions, and products designed for ease of use and maintenance within limited spaces. Buyers should consider if the item’s dimensions and capabilities genuinely suit a modest outdoor area before making a purchase.

What is PVC?

PVC stands for Polyvinyl Chloride. It’s a synthetic plastic material widely used in home and garden products due to its durability and affordability. When you see ‘PVC’ listed as a material specification, it generally indicates that the product is made from this type of plastic. PVC is relatively hard-wearing and resistant to water damage, making it suitable for items like hoses, bath mats, and outdoor furniture where exposure to the elements is common. However, it can be less environmentally friendly than some other materials and may require specific cleaning methods – typically mild soap and water – to maintain its appearance.

What is Large gardens?

When a product is described as suitable for ‘Large gardens’, it generally refers to items designed for outdoor spaces covering a significant area – typically over 1000 square metres. For tools like lawnmowers and composters, this indicates the item should be robust enough to handle extended use across a bigger plot, potentially needing regular maintenance and capable of processing substantial volumes of material or cutting larger lawns efficiently. Buyers should consider factors such as weight for manoeuvrability, power requirements (for electric models), and overall build quality when assessing suitability – larger gardens demand greater durability and performance.

What is Recycled plastic?

Recycled plastic refers to plastic materials that have been recovered from waste streams and reprocessed into new products. When a product is described as ‘made from recycled plastic’ it means the plastic used in its construction originated as discarded items, such as bottles or packaging. For a UK shopper, this indicates a potential shift towards more sustainable material choices. Recycled plastics can vary slightly in quality compared to virgin plastic; they might be heavier and potentially less UV resistant over time, requiring careful consideration regarding long-term outdoor use and maintenance. The specific properties will depend on the source of the recycled plastic used.

What is Gas?

In the context of home & garden products like BBQs and patio heaters, "Gas" refers to the fuel source used for operation – specifically, liquefied petroleum gas (LPG) or propane. It indicates that the appliance is designed to burn this gaseous fuel instead of solid fuels such as charcoal or electricity. UK buyers should understand that gas appliances require a supply of refillable cylinders, and ongoing maintenance involves checking cylinder levels and ensuring proper ventilation when in use. Gas appliances are generally lighter than their electric counterparts but can be more susceptible to weather conditions affecting performance.

What is Composite?

Composite materials used in home & garden products like decking and furniture are created by combining two or more different materials – typically a plastic (often recycled polyethylene) with wood fibers. This blend offers advantages over traditional timber: it's significantly more resistant to weathering, rot, and insect damage, reducing the need for frequent painting or treating. Composite materials are often heavier than natural wood but lighter than some hardwoods. They tend to be more expensive initially, however, their lower maintenance requirements can result in long-term cost savings.

What is Polycarbonate?

Polycarbonate is a strong, transparent plastic material known for its durability and resistance to impact. In the context of home & garden items like greenhouses and cold frames, it’s frequently used as a glazing – meaning it forms the clear panels that let in light. It's significantly tougher than standard glass, offering better protection against accidental damage or weather conditions. Polycarbonate is also lighter than glass, which can make installation easier, though it may be more expensive upfront. Maintaining polycarbonate requires regular cleaning to remove dirt and debris for optimal light transmission.

What is 1/2 inch?

When referring to the size of items like garden hoses and watering equipment, "1/2 inch" describes the internal diameter of a tube or pipe. This measurement indicates the volume of water that can flow through it per unit of time – essentially, how quickly it will deliver water. A larger 1/2 inch hose will generally allow for a greater flow rate compared to a smaller one. Consider this when choosing equipment; a larger diameter often means easier use, especially when dealing with high pressure or longer distances. It’s also worth noting that hoses with a larger internal diameter may be slightly heavier.

What is Stoneware?

Stoneware is a type of ceramic clayware known for its durability and robust construction. It’s typically fired at higher temperatures than earthenware, resulting in a denser material that's more resistant to chipping and cracking. When you see stoneware listed as a material specification for home & garden items like dinnerware or planters, it suggests the product is likely built to withstand everyday use. Stoneware tends to be heavier than lighter ceramics, and requires similar care to other ceramic materials – avoiding drastic temperature changes and rough handling will help maintain its quality.
