Mottlecah (Eucalyptus macrocarpa)
Also known as: Blue bush, Rose of the west
Mottlecah, native to Western Australia, typically blooms with striking red flowers from late spring to early summer. It thrives in Mediterranean climates, characterized by hot, dry summers and cool, wet winters. Once established, this hardy tree can endure challenging conditions such as drought and frost. Honeyeaters are particularly attracted to its nectar-rich flowers.

How to Water Mottlecah?
Eucalyptus macrocarpa prefers to have its soil thoroughly soaked and then allowed to dry out between waterings. Ensure the water fully penetrates the root zone, approximately 250 ml per watering session is ideal to mimic its natural arid environment.

What Is the Ideal Temperature Range for Mottlecah?
Eucalyptus macrocarpa prefers a warm climate with temperatures consistently between 60°F and 75°F. These conditions replicate its native Australian environment, promoting robust growth and vibrant flowering. Ideally, maintaining stable temperatures within this range ensures optimal photosynthesis and overall plant health.
What Soil is Best for Mottlecah?
Eucalyptus macrocarpa thrives in well-drained soils that prevent waterlogging. This is crucial as excess water can harm root development and lead to fungal diseases, ensuring robust and healthy growth. The plant prefers moderately nutrient-rich soil to support its impressive foliage and vibrant flowers. This supply of nutrients fosters robust growth and vibrant colors, making your garden stand out. While the soil should drain well, it also needs the ability to retain some moisture, especially during dry spells. This balanced moisture environment supports sustained growth during different weather conditions.
How to Fertilize Mottlecah?
For Eucalyptus macrocarpa, use a balanced, low-phosphorus fertilizer. Given the plant's moderate nutrient needs, apply liquid fertilizer at a rate of 1 teaspoon per gallon of water for young plants. Mature plants are more resilient and may require slightly more, approximately 1.5 teaspoons per gallon.
How to Prune Mottlecah?
To prune Eucalyptus macrocarpa, start by sterilizing your pruning shears to prevent disease spread. Focus on removing dead or damaged branches first, cutting them back to their base. Next, shape the tree by trimming overly long branches, making sure to cut just above a node to encourage new growth. Pruning during active growing seasons like spring and summer can maximize branching and vitality. Occasionally, deeper pruning may be needed to rejuvenate older or neglected Eucalyptus macrocarpa plants. Cut back the main branches more vigorously to promote new, vigorous growth. Ensure that at least a third of the mature structure remains to sustain the plant. Post-pruning, water and fertilize adequately to aid recovery.

How to Propagate Mottlecah plant?
1
Start by preparing a well-draining soil mix for the seeds or cuttings. This ensures that the roots can develop without excess water causing rot. A mixture of sand and peat moss is generally recommended.
2
Scatter the seeds over the soil surface and lightly cover them with a thin layer of soil. Ensure that the seeds are evenly spaced to allow ample room for each to grow properly.
3
Select healthy branches from the parent plant. Cut a section of about 10 cm in length. Remove the leaves at the bottom of the cutting before planting it into the prepared soil.
How to Repot Mottlecah plant?
1
Watch out for roots circling the pot’s edges or growing through drainage holes; these are clear signs Eucalyptus macrocarpa needs repotting. If nutrient uptake appears stunted despite feeding, it suggests soil compaction, indicating a repotting necessity. Finally, if water drains quickly, this signals reduced soil volume and effectiveness.
2
Choose a pot that is one to two sizes larger than the current one, ensuring it has ample drainage holes. A larger pot prevents root-bound issues, promotes healthy root expansion, and allows adequate soil for moisture retention, which is crucial for this plant to thrive.
3
Opt for a well-draining, sandy soil mix enriched with organic matter for Eucalyptus macrocarpa. This soil type prevents waterlogging, reducing root rot risks. Its loose texture encourages better root penetration and air circulation, crucial for vigorous plant health and growth.
