WaterThe Birthday Candles Banksia requires moderate watering, usually about 1 inch per week. During hot, dry periods, water thoroughly to moisten the soil to a depth of 8 to 10 inches every two weeks. They prefer to dry out slightly between waterings, so ensure the soil is not constantly wet. Overwatering can damage the plant's health. It's best to water the plant early in the morning to allow the foliage time to dry before evening.
LightBirthday Candles Banksia thrives in full sun but can tolerate partial shade. Plant it in a location where it will receive at least 6 to 8 hours of direct sunlight each day. Avoid deep shade, as insufficient light can lead to poor flowering and leggy growth. Good exposure to sunlight supports the best health and flowering in this shrub.
TemperatureThe ideal growing temperatures for Birthday Candles Banksia are between 50°F and 70°F. They are hardy and can survive minimum temperatures down to about 20°F, but they should be protected from frost. These plants can withstand high temperatures but may require additional watering in extreme heat.
PruningPruning Birthday Candles Banksia is essential to maintain its shape and encourage more prolific flowering. It should be pruned right after the flowers have faded, typically late spring or early summer. Remove spent flower spikes and lightly shape the plant, cutting back any unruly or long shoots to promote bushiness. Avoid heavy pruning, which can damage the plant.
CleaningAs needed
SoilBirthday Candles Banksia prefers well-drained, sandy loam soil with a slight acidic to neutral pH of around 5.5 to 6.5. The best soil mix for this dwarf banksia is a combination of equal parts sand, loam, and peat moss or well-rotted compost to ensure good drainage and aeration. Regularly test the soil pH to maintain the desired acidity, and amend with sulfur if it becomes too alkaline. Avoid heavy, clay-based soils which retain moisture, as poor drainage can lead to root rot.
RepottingBirthday Candles Banksia is a slow-growing plant and does not need to be repotted frequently. It typically requires repotting every 2 to 3 years. Choose a pot only slightly larger than the previous one to avoid overly damp soil which can promote root rot. The best time to repot is in the late winter or early spring before new growth begins. Ensure the new pot has adequate drainage holes.
Humidity & MistingBirthday Candles Banksia is tolerant of a range of humidity conditions but thrives best in moderate to low humidity environments. Native to Australia, this dwarf banksia is adapted to dry conditions and does not require high humidity levels. Indoor air is usually sufficient for this plant, and no special humidity adjustments are necessary. Avoid creating overly humid conditions as it may encourage fungal diseases.

Life cycleBanksia spinulosa 'Birthday Candles' begins its life as a seed, which requires exposure to smoke or fire to break its dormancy and initiate germination. Once the seedling emerges, it enters a juvenile growth phase where it develops a deep root system and foliage, without producing flowers. The plant reaches maturity within a few years, during which it develops a woody trunk and starts to flower annually, typically from late summer to winter. Flowers are cylindrical spikes, with styles that start out yellow and age to a rusty red. After pollination, typically involving birds and insects, the flowers develop into follicles that hold the seeds and require another fire event to open and release seeds for the next generation. The plant can live for many years, continuing to grow, flower, and reproduce, while also being able to resprout from its lignotuber after adverse events like fires.
PropogationPropogation time
Late Summer to Autumn
Banksia spinulosa 'Birthday Candles,' commonly known as Dwarf Banksia, can be propagated through seed or cuttings. The most popular method for this cultivar is via cuttings, as seed propagation can often result in plants that are variable and not true to the parent's form. The ideal time to take cuttings is during the summer months when the plant is actively growing. Select semi-hardwood cuttings about 4 to 6 inches (10 to 15 centimeters) in length, ensuring each cutting has at least one node and several leaves. Dip the cut end in rooting hormone powder to encourage root growth and plant it in a well-draining propagation mix. Maintain humidity and keep the soil consistently moist but not waterlogged. Rooting typically occurs within a few months, after which the new plants can be gradually acclimated to less humid conditions and eventually planted out.
