Lemon-scented gum (Corymbia citriodora)

When watering Corymbia citriodora, aim to provide approximately 1000 ml of water. The soil should be kept moist but not waterlogged. It's essential to allow the top 2 inches of the soil to dry before the next watering. This ensures that the plant gets adequate moisture without causing root rot. If you're growing it outdoors, ensure that it gets a generous soak, especially during hot, dry spells.

Corymbia citriodora thrives ideally under conditions of full sun to partial sun, where it can benefit from at least 6 hours of direct sunlight. Sufficient light exposure aids in luxuriant leaf growth and robust aromatic oil production, essential for its characteristic fragrance and pest resistance.

Corymbia citriodora thrives within an ideal temperature range of 64°F to 75°F. This range provides the optimal thermal conditions necessary for strong growth and development, including the maintenance of their unique aromatic properties. At this range, the physiological processes of the plant, including photosynthesis and respiration, occur efficiently, allowing for the healthiest development of foliage and overall plant vigor.

Corymbia citriodora thrives best in well-draining soil, which prevents waterlogging that could lead to root rot. This condition also allows roots to access oxygen better, essential for healthy growth and vitality. A nutrient-rich loamy soil provides essential minerals and nutrients, promoting robust foliage growth and vibrant leaf color. Such soil aids in plant resilience against pests and diseases. Balancing moisture is key; the soil should retain enough water to support the plant’s needs but not so much that it becomes soggy. This helps in sustaining the plant during dry spells while preventing over-saturation.

For Corymbia citriodora, when using liquid fertilizer, it is ideal to apply at half the recommended strength to avoid any risk of over-fertilization. For slow-release granules, use approximately one tablespoon per square foot of soil surface.

Begin by inspecting the tree for any dead or damaged branches, which should be removed first. Make clean cuts close to the trunk or main limb, using sharp, sterilized tools to avoid disease spread. To shape the canopy, selectively prune branches that cross each other or grow inwards. Focus on creating an open structured canopy to allow light and air to penetrate, which benefits the plant's health and growth. If height control is necessary, prune the higher branches down to a lateral branch. This ensures the tree maintains a manageable size while promoting the growth of lower branches, balancing the overall shape.
