Picking a container size for a landscape specification is partly budget, partly visual outcome, and partly establishment risk. A specification that lands the right size on day one delivers a planting that reads correctly inside the project handover, establishes cleanly through the first summer, and saves replacement budget over the warranty period. Get it wrong in either direction and the project either looks unfinished for two years or burns budget on stock the site cannot reliably establish.
The container-size ladder: from tube stock to landmark specimen
Cape Nursery produces across 24 size tiers. The numbers below are the most commonly specified bands and what each one typically delivers on day one for fast-growing screening cultivars in subtropical and warm-temperate Australia.
| Size | Volume | Day-one height | Establishment-ready | Typical use |
|---|---|---|---|---|
| 140mm tube | ~1.5 L | 20–40 cm | Yes | Mass-planting, restoration, council revegetation |
| 200mm | ~5 L | 40–60 cm | Yes | Standard hedging brief, screening at scale |
| 300mm | ~12 L | 60–90 cm | Yes | Medium hedging, residential screening |
| 430mm | ~35 L | 1.0–1.5 m | Yes | Quick-effect hedging, instant impact |
| 100 L | 100 L | 1.5–2.5 m | Yes | Advanced hedge, semi-advanced feature |
| 200 L | 200 L | 2.5–3.5 m | Yes | Advanced specimen, semi-mature screen |
| 400 L | 400 L | 3–5 m | Yes | Feature specimen, instant canopy |
| 1000 L | 1000 L | 4–7 m | Yes | Landmark specimen, mature visual impact |
The "establishment-ready" column reflects Cape Nursery's standard production: every size in the table is grown to the point where its root mass fills the container without circling, the stem is structurally sound, and the foliage is hardened to coastal conditions. Stock from any nursery should clear that bar before being specified — root condition matters more than container size on its own.
How to choose: three questions, one answer
The right container size for a project comes from three questions, asked in this order:
1. What does the project handover look like?
If the planting needs to read as established at handover (display village, hospitality opening, civic ceremony tied to a date), specify advanced sizes — 100L for hedges, 200L+ for feature trees. The premium over smaller stock is bought back in not having to apologise for an unfinished landscape on opening day.
If the project is being handed over with an explicit "12–18 month establishment" window built into the brief, smaller stock — 200mm for hedges, 100L for features — performs equivalently with much lower stock budget and equivalent quality at month 18.
2. What is the maintenance program?
Advanced specimens have less establishment forgiveness than smaller stock. A 400L tree that misses three deep waterings in its first month will go backwards visibly; a 200mm that misses the same waterings will recover quietly. If maintenance is light or unpredictable (council verge planting, contractor handover before maintenance contracts begin), bias toward smaller, more resilient stock.
3. What is the site exposure?
Coastal-frontline and high-wind sites favour smaller, more flexibly-rooted stock that can self-establish a wind-resistant root architecture. Advanced specimens specified into exposed sites need careful staking and longer establishment programs to avoid wind-rock failure. Buffer-zone and hinterland sites tolerate the full size range without penalty.
"Advanced" vs "semi-advanced" vs "establishment": what the labels mean
Industry terminology varies, but the conventional bands at Cape Nursery are:
- Establishment stock — 140mm and 200mm. Best on multi-year horizons, mass plantings, projects with active maintenance. Lowest risk per dollar of stock cost.
- Semi-advanced — 300mm to 100L. The most-commonly-specified band for residential and commercial screening. Reads as a hedge inside 6–9 months.
- Advanced — 200L to 400L. Reads as established at handover. Used for feature trees, landmark specimens, time-pressured installs.
- Landmark / specimen — 1000L+. Reserved for civic, heritage, and high-value private projects where the size is part of the design intent rather than just a time-saver.
Common size-specification mistakes
- Specifying advanced for budget reasons. Larger trees feel like better value but actually carry higher establishment risk on under-maintained sites. The cost of a single 400L specimen failure exceeds the budget delta from speccing 100L throughout.
- Specifying small for time-pressured projects. 200mm hedging on a development with a six-month sales window will not read as a hedge by handover. Specify the 100L on visible faces and 200mm in the back-of-site.
- Mixing sizes in a single hedge run. Visible variation in starting height takes 18+ months to even out. Spec one size per run.
- Ignoring root condition. A 400L specimen with a girdled or circling root system is a worse outcome than a clean 100L. Inspect root condition before accepting on-site, regardless of container size.
