Cultivation
Banksia attenuata, also known as Candlestick Banksia, is a shrub that grows up to 6 meters in height. It's indigenous to Western Australia and requires a warm, sunny, and dry climate for optimal growth. Plant the seedlings in well-draining soil that's rich in organic matter and keep it moist until they are established.
Watering needs
Banksia attenuata is drought-tolerant and requires less water than other plants. However, regular watering is necessary during the growing season to keep the soil moist. Overwatering should be avoided as it can lead to root rot.
Fertilization
Use a slow-release fertilizer during the growing season to nourish the plant. Banksia attenuata requires a moderate amount of nutrients to grow and prosper. Actively growing plants should be fertilized every month or two, while mature plants require fertilization once every three to four months.
Pruning
Banksia attenuata requires minimal pruning as it grows naturally in a bushy form. However, it's recommended to remove damaged or diseased wood immediately. Trimming the plant's branches during the winter dormancy period is also acceptable. Avoid pruning during the growing season as it may cause the plant to produce fewer flowers.
Propagation of Banksia Attenuata
Banksia attenuata is commonly propagated through seed. Propagation through cuttings is possible but not recommended. The best time to collect seed is during the autumn and winter months.
Seed Collection and Preparation
When collecting seed, look for cones that have started opening or have already opened. The cones can be collected from the parent plant or from under the parent plant. Once collected, the cones should be kept in a dry, well-ventilated area until they have fully opened.
To extract the seed, gently pull the cone apart and remove the woody part. The seed should be cleaned and any debris should be removed. Banksia attenuata seeds require no pre-treatment before planting.
Planting
Banksia attenuata seeds should be planted in well-draining soil that is moist but not waterlogged. A sandy soil mix is ideal. The seed should be placed just below the surface of the soil and covered lightly with a thin layer of soil. Water the soil gently, taking care not to disturb the seed.
The seeds should be kept warm and moist until they germinate, which usually occurs within 4 to 6 weeks. The use of a greenhouse or similar structure will help to provide the ideal growing conditions for the seeds.
Caring for Seedlings
Once the seedlings have emerged, they should be kept in a warm, well-lit area. They should be kept moist but not waterlogged, and the soil should be allowed to dry out slightly between waterings. When the seedlings have grown to around 5cm, they can be transplanted into individual pots or a larger container. Banksia attenuata is a slow-growing plant and can take several years to reach maturity.
