How to Grow
๐ Choosing a Location
To thrive, the Two-Colored Cestrum needs full sun exposure, ideally basking in 6-8 hours of sunlight daily. It flourishes in USDA zones 9-11, making it perfect for warmer climates.
๐ฑ Soil Preparation
This plant prefers well-drained, fertile soil that allows for healthy root development. Aim for a soil pH between 6.0 and 7.0, which is slightly acidic to neutral.
๐ฟ Planting Techniques
When planting, dig a hole thatโs 1-2 inches deep to accommodate the roots. Space your plants 2-3 feet apart to ensure they have room to grow and flourish.
๐ง Watering Requirements
Initially, keep the soil consistently moist until the plant is established. After that, moderate watering is key; allow the soil to dry out between waterings to prevent root rot.
๐ผ Fertilizing Schedule
During the growing season, apply a balanced NPK fertilizer every 4-6 weeks. This will provide the necessary nutrients for robust growth and vibrant blooms.
โ๏ธ Pruning Methods
Prune your Cestrum in early spring, just before new growth begins. Focus on removing any dead or damaged branches to encourage a bushier appearance.
