Supplied as Dormant Tubers

Supplied as the selected quantity of dormant Dahlia ‘Gambier Jane’ tubers.

Planting Instructions

Plant Dahlia ‘Gambier Jane’ during spring once the danger of frost has passed and the soil has begun to warm.

Choose a sunny position with fertile, free-draining soil. Avoid low-lying areas where water collects, as dormant tubers can rot when planted in continually wet soil.

Lay each tuber horizontally approximately 5–10cm below the soil surface, with the crown or growing point facing upwards. Cover gently with soil.

Space plants approximately 60cm apart to provide sufficient room for growth and good airflow.

Install a sturdy stake at planting time. Adding support before the plant begins growing helps prevent accidental damage to the tuber later.

Avoid heavy watering immediately after planting. If the soil is already moist, wait until shoots begin appearing before commencing regular watering.

Care Instructions

Position

Grow Dahlia ‘Gambier Jane’ in full sun, ideally with at least six hours of direct sunlight each day.

In hot Australian climates, protection from intense late-afternoon sun may help reduce heat stress and preserve flower quality.

Insufficient sunlight can result in weaker stems, softer growth and reduced flowering.

Soil

Plant in fertile, humus-rich and free-draining soil.

Improve the planting area with compost or well-aged organic matter before planting. Heavy clay soil should be amended to improve drainage, or the tuber can be grown in a raised garden bed or large container.

Excellent drainage is particularly important in subtropical climates and areas receiving heavy summer rainfall.

Watering

Once shoots emerge, water deeply and regularly while allowing the upper surface of the soil to begin drying between applications.

Increase watering during hot, dry or windy weather. Avoid keeping the soil continually saturated, particularly around the crown and tubers.

Water near the base of the plant where possible to reduce prolonged moisture on the foliage and flowers.

Feeding

Apply a balanced or flowering-plant fertiliser once active growth is established.

Avoid excessive nitrogen, which can encourage abundant foliage at the expense of flower production. Additional flowering fertiliser may be applied when buds begin developing, following the product label directions.

Staking

Dahlia ‘Gambier Jane’ typically grows approximately 1.2–1.5m tall, so support is recommended.

Install a sturdy stake at planting time and secure the stems loosely as the plant grows. Allow enough space for natural movement and stem expansion.

Plants grown in windy or exposed positions may require additional ties or support.

Pinching

For bushier growth and additional flowering stems, pinch out the central growing tip once the young plant has developed approximately four or five sets of leaves.

Pinching may delay the first flowers slightly but can encourage a fuller plant with more flowering branches.

Deadheading and Cutting

Remove faded flowers regularly to encourage continued blooming and prevent the plant from directing energy into seed production.

Flowers intended for arrangements are best cut during the cooler part of the morning. Choose flowers that are nearly or fully open and place the stems into clean water promptly after cutting.

Regular cutting and deadheading can help extend the flowering season.

Hot and Humid Climates

In subtropical and humid regions, provide excellent drainage and generous spacing between plants.

Good airflow helps reduce the risk of fungal problems. Avoid continually wet foliage and water early enough for the leaves to dry before evening.

Protection from the hottest afternoon sun may help preserve the cream-white areas and reduce heat stress.

End-of-Season Care

After flowering, allow the foliage to remain until it begins yellowing and dying back naturally. This enables the plant to return energy to its tubers.

In mild climates with free-draining soil, the tubers may be left in the ground during dormancy. Mark the planting position and keep the area relatively dry.

Established clumps can be lifted and divided periodically to prevent overcrowding and maintain vigorous growth.

In cold, frost-prone or persistently wet climates, lift the tubers after the foliage has died back. Allow them to dry before storing them in a cool, dark, frost-free and well-ventilated location.
