Container Grown plants are trees, shrubs, and hedging plants that have been cultivated in pots or containers for at least 12 months, developing a complete, undisturbed fibrous root system within their growing medium. Unlike field grown plants that are lifted from open ground, container grown plants are sold with their roots fully contained in compost, allowing them to be transplanted without any root disturbance.
Year-Round Planting Flexibility
The most significant benefit of container grown plants is their extended planting season. Unlike bare root or field grown alternatives, container plants can be planted at any time of year provided the ground isn't frozen or waterlogged. This makes them ideal for summer projects, last-minute landscaping, or when construction schedules don't align with traditional planting windows.
Higher Success Rate
Container grown plants offer a near 100% transplanting success rate. Because the root system remains completely intact and undisturbed during the planting process, the plant experiences minimal transplant shock and establishes quickly in its new position.
Convenience & Handling
These plants are generally easier to transport and handle on site. They can remain in their pots for extended periods before planting without suffering deterioration, providing valuable flexibility if project delays occur.
Instant Impact
Container grown stock is available in larger girth sizes (up to 30-35cm and beyond), allowing for immediate visual impact in landscape projects without the wait associated with smaller planting stock.
Considerations
Higher Cost
Container grown plants typically cost more than bare root alternatives, this reflects the additional nursery care required, including regular irrigation, feeding, and re-potting as plants mature.
Irrigation Requirements
Particularly when planted during warmer months, container grown trees may require significant watering—up to 20 litres daily for larger specimens—until fully established.
Potential for Root Circling
If left in containers too long without proper root pruning or re-potting, roots may begin circling the pot, potentially affecting long-term establishment if not addressed at planting time.
Weight & Transport Costs
The inclusion of potting compost and containers adds considerable weight, increasing transport costs compared to bare root stock.
