Ponds and water features, ongoing care
A pond needs regular maintenance (algae control, pump checks, seasonal clearing) beyond the initial installation — worth factoring ongoing care into the decision, not just the upfront cost of installing a water feature.
Garden lighting, planning it properly
Outdoor lighting needs weatherproof (IP-rated) fittings and, for anything beyond simple solar lights, a qualified electrician for the wiring — this crosses into notifiable electrical work under Part P if it involves a new circuit. Worth planning cable routes during any hard landscaping work, not after paving is laid.
Fast-growing screening plants vs slower alternatives
Fast-growing hedging like leylandii gives quick privacy but needs frequent trimming and can grow larger than intended if neglected. Slower-growing alternatives need more patience but are generally easier to maintain at a manageable size long-term — worth discussing growth rate expectations before choosing.
Background checks and insurance
Since gardening isn't gated by a mandatory certification, checking trading history, reviews referencing specific local jobs, and confirming public liability insurance matters more than for trades with formal registration bodies — ask to see proof of insurance for anything beyond routine maintenance.
Understanding the labour vs materials split
For hard landscaping, materials (paving, decking, fencing) are often a large share of cost, but groundwork labour (excavation, base preparation, drainage) matters just as much for how the finished job performs. A cheap quote is worth checking against the same material spec and base preparation as competing quotes.
Guarantees on landscaping work
Hard landscaping (patios, walls, decking) commonly comes with a workmanship guarantee, typically shorter than a building trade's (often 1-2 years). Planting generally isn't guaranteed the same way since plant survival depends on aftercare, weather and site conditions beyond the installer's control.
How gardening quotes work
For regular maintenance, an initial visit lets a gardener assess plot size and current condition for an ongoing price. For a one-off landscaping project, describe the scope and any inspiration/reference images — a firm quote usually follows a site visit, since ground condition and access affect cost significantly.
Common garden pests and wildlife considerations
Some pest issues (slugs, aphids) are routine and manageable with regular maintenance; others (Japanese knotweed, certain invasive species) need specialist treatment and have legal disposal requirements. If you're unsure what you're dealing with, it's worth getting it identified before attempting treatment yourself.
