Planting gives a landscape scale, shade, privacy, texture and seasonal change, but it is also the part of the garden most sensitive to poor specification. Plants that look attractive at purchase can fail when placed in the wrong exposure, crowded into inadequate soil, irrigated as one undifferentiated zone or selected without considering mature size. A resilient planting plan uses the site conditions as its filter.
Start with microclimate
Map full sun, reflected heat, filtered shade, deep shade, wind exposure and sheltered areas. Conditions can change sharply within a single property. A plant that performs beside a shaded north wall may struggle beside glazing or a west-facing boundary.
Select by function
Every plant should have a job: shade, screening, framing, focal point, ground cover, erosion control, fragrance, seasonal colour or softening hard architecture. Function creates a more disciplined palette and prevents unnecessary variety.
Allow for mature size
Check mature height and spread rather than nursery size. Trees need adequate root volume and clearance from walls, pools and services. Shrubs planted too closely create long-term pruning and pest problems.
Build a hierarchy
Use a small number of structural trees, a repeated middle layer of shrubs or grasses and a controlled ground layer. Repetition creates calm and makes maintenance more predictable. Feature plants work best when they remain exceptional.
Group by water demand
Hydrozoning places plants with similar water needs together. This supports healthier irrigation scheduling and avoids the common problem of overwatering drought-tolerant plants while trying to support thirstier species.
Consider soil and drainage
Imported soil quality, compaction, drainage and organic matter can strongly affect performance. Planting pits should not become isolated bowls that retain water. Soil improvement needs to suit the plant palette and irrigation method.
Use trees strategically
Trees can provide shade, screen upper-storey views, frame architecture and establish scale. Their selection must consider root behaviour, litter, maintenance, growth rate, canopy form and proximity to structures.
Screening requires depth
A single hedge can provide privacy, but layered planting is often more resilient and visually interesting. Combine a structural screen with selected trees or accents, and leave enough depth for access and mature growth.
Colour should support structure
Flowers and foliage colour are most effective when the underlying structure is strong. Use seasonal colour as an accent rather than relying on continuous high-input display planting across the whole garden.
Plan establishment and replacement
New planting needs closer observation while roots establish. Agree the establishment-care period, irrigation checks, replacement policy and pruning approach before handover.
