APL, BALI and HTA, what they mean
The Association of Professional Landscapers (APL) is a TrustMark scheme operator for landscaping. BALI (British Association of Landscape Industries) and the HTA (Horticultural Trades Association) are the other main trade bodies. None of these are legally required, and membership varies across the industry — worth asking which, if any, a gardener holds rather than assuming it's standard.
Regular maintenance vs one-off visits
A maintenance contract (fortnightly or monthly visits) usually works out cheaper per visit than booking one-off gardening, and means a gardener gets to know the specific garden over time. One-off visits suit gardens that need less frequent attention or where needs vary a lot seasonally.
Garden drainage and irrigation
Poor drainage (waterlogging after rain, a consistently boggy patch) is often fixable with a French drain or soakaway rather than needing a full garden regrade — worth getting properly diagnosed before assuming the whole garden needs releveling. Irrigation systems are more relevant for larger gardens or specific planting that needs consistent watering.
Raised beds and vegetable gardens
Raised beds improve drainage and soil quality control, useful where existing soil is poor or compacted, and make gardening more accessible for anyone who finds ground-level bending difficult. Positioning for sun exposure matters more for a productive vegetable bed than for purely ornamental planting.
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.
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.
Three steps to hiring the right gardener
First, ask to see photos of similar completed work, ideally local gardens. Second, for larger projects, get a written quote specifying materials and scope. Third, ask about public liability insurance, particularly for any work involving power tools, ladders, or structural landscaping.
What affects the cost
Cost depends on plot size, whether it's regular maintenance or a one-off project, materials (paving type, decking vs artificial grass), and access for machinery or skips on larger jobs. A garden clearance before a redesign is often quoted separately from the landscaping work itself.
