Hydrangea Macrophylla Red

• Hydrangea Macrophylla Red originates from Japan and has been cultivated for centuries for its spectacular blooms. It's one of the most popular deciduous shrubs in temperate gardens worldwide.
• The large mophead flowers can reach 15-20cm across and change intensity based on soil pH. Red varieties maintain their colour best in neutral to slightly alkaline soils.
• This variety grows as a rounded, bushy shrub with lush green foliage that provides excellent texture even when not in bloom. The leaves turn attractive bronze tones in autumn before dropping.
• Gardeners love this hydrangea for its long flowering season, low maintenance requirements, and versatility in garden design. It's perfect for cottage gardens and contemporary landscapes alike.

• Water regularly throughout the growing season, keeping soil consistently moist but not soggy. Reduce watering in winter when the plant is dormant.
• Position in morning sun with afternoon shade for best results, particularly in warmer Australian climates. Protection from hot afternoon sun prevents leaf scorch and maintains flower colour.
• Plant in rich, well-draining soil enriched with compost and aged manure. Add sulphur or use acidic potting mix to maintain slightly acidic to neutral pH for best red colour.
• Feed with a controlled-release fertiliser for acid-loving plants in spring and liquid feed monthly during active growth. Avoid high-phosphorus fertilisers which can inhibit flowering.
• Prune lightly after flowering to remove spent blooms and shape the plant. Avoid cutting back hard as flowers form on previous season's wood.
• Mulch generously with organic matter to retain moisture, suppress weeds, and keep roots cool during summer heat. Refresh mulch annually in spring.
• Monitor for pests like aphids and spider mites, particularly on new growth. Treat promptly with appropriate organic or chemical controls.
• Protect from strong winds and frost in exposed positions. In very cold areas, consider applying extra mulch around the root zone in late autumn.

• Plant in a position with morning sun and afternoon shade, especially in warmer Australian regions. Too much direct sun will scorch leaves and fade flower colour.
• Water deeply 2-3 times weekly during summer, more frequently in pots. Keep soil consistently moist but never waterlogged during the growing season.
• Apply a thick layer of organic mulch around the base to retain moisture and keep roots cool. Maintain mulch away from the main stem to prevent rot.
• Feed with a slow-release fertiliser for acid-loving plants in early spring and again in summer. This supports abundant flowering and healthy foliage growth.
• Prune after flowering finishes in late summer or autumn, removing old flower heads just above strong buds. Avoid heavy winter pruning as flowers form on old wood.

• Aphids and spider mites can appear on new growth during warmer months. Spray with horticultural oil or insecticidal soap, repeating weekly until pests are controlled.
• Powdery mildew develops in humid conditions with poor air circulation. Improve spacing between plants and avoid overhead watering to prevent fungal issues.
• Yellowing leaves often indicate iron deficiency in alkaline soils. Apply iron chelate and use acidic fertilisers to maintain optimal soil pH.
• Root rot occurs from overwatering or poor drainage. Ensure soil drains freely and allow the top layer to dry slightly between waterings.
