Tree work and when you need a specialist
Basic pruning and hedge work is within most gardeners' scope, but significant tree work (felling, major crown reduction) is more specialised and, for larger trees, benefits from a qualified arborist. Check whether a tree has a Tree Preservation Order or sits in a conservation area before any significant work — this can restrict what's allowed.
Accessible garden design
Level or gently sloped paths, raised beds, and wider gateways make a garden more usable for anyone with mobility considerations — worth planning these into a redesign from the start, since retrofitting accessibility into an already-completed hard landscaping scheme is more disruptive and costly.
Understanding your soil before planting
Soil type (clay, sandy, chalky) significantly affects what plants will thrive without heavy intervention — a simple soil test before a planting scheme is decided can save money on plants that would otherwise struggle in unsuitable conditions.
What a good landscaping quote should include
A proper quote should specify materials by name/grade (not just "paving" or "decking"), whether waste removal and disposal is included, and an estimated timeline that accounts for weather-dependent work. Ongoing maintenance quotes should state visit frequency and exactly what's covered each visit.
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.
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.
Red flags in a cheap gardening quote
A quote well below others for landscaping work is worth questioning — check it specifies the same material grade and includes proper groundwork/drainage preparation, not just the visible surface. No public liability insurance, cash-only payment, and pressure to decide immediately are all worth treating with caution.
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.
