Hydrangea Assorted

• Native to Asia, hydrangeas have been cherished garden plants for centuries and adapt well to Australian temperate climates. They're deciduous shrubs that provide seasonal interest through changing foliage.
• Flower colour changes based on soil pH - acidic soil produces blue flowers while alkaline soil creates pink blooms. White varieties remain consistent regardless of soil conditions.
• Popular for cut flower arrangements as blooms last well in vases and can be dried for lasting displays. Flowers appear in large clusters from late spring through summer.
• Growth habit ranges from compact varieties perfect for containers to larger specimens ideal for hedging and screening applications in Australian gardens.

• Water deeply twice weekly during active growth, reducing to weekly in winter - check soil moisture 5cm down before watering. Mulch heavily to retain consistent moisture.
• Position in morning sun with afternoon shade protection, particularly important in hot Australian climates. Avoid windy exposed locations that can damage large flower heads.
• Plant in well-draining acidic to neutral soil enriched with compost and organic matter. Add sulfur to lower pH for blue flowers or lime for pink.
• Feed monthly with balanced liquid fertiliser during spring and summer growing season. Avoid high nitrogen feeds which promote foliage over flowers.
• Prune lightly after flowering finishes, removing spent blooms and dead wood only. Major pruning should wait until late winter before new growth appears.
• Maintain humidity with regular deep watering and organic mulch around root zone. Group with other plants to create favourable microclimate.

• Provide morning sun with afternoon shade protection, especially during harsh Australian summers. Avoid full sun exposure which can scorch leaves and fade flowers.
• Water deeply twice weekly during growing season, maintaining consistent soil moisture without waterlogging. Reduce to weekly watering in cooler months.
• Maintain humidity around plant by mulching heavily and grouping with other plants. Mist around plant base during dry periods.
• Protect from strong winds and frost in exposed locations. Provide shelter during extreme weather events common in Australian conditions.
• Feed monthly during spring and summer with balanced fertiliser to promote abundant flowering. Stop feeding in autumn to prepare for dormancy.

• Aphids cluster on new growth and flower buds - spray with horticultural oil or insecticidal soap early morning. Check undersides of leaves weekly during growing season.
• Powdery mildew appears as white dust on leaves in humid conditions - improve air circulation and avoid overhead watering. Remove affected leaves immediately.
• Overwatering causes yellowing leaves and root rot - ensure excellent drainage and allow soil to dry between waterings. Reduce watering frequency in winter.
• Scale insects create sticky honeydew on stems - treat with white oil spray and physically remove with soft brush. Monitor regularly during warm months.
