6 Planting and Caring for Bougainvillea
Planting Techniques
Preparation
- Before planting, prepare cuttings and soil to ensure the plant’s healthy growth and early flowering.
- For cuttings, select branches that are 1-2 years old, with a length of about 20cm, and have at least two nodes.
Soil Preparation: Use well-drained, nutrient-rich soil with some added sand and husk for aeration. Avoid overly moist soil as bougainvillea tolerates drought well. You can also add decomposed manure to the soil.
Proper cutting techniques are crucial for the plant’s development and flowering.
Planting
Choose a cool season for planting, such as autumn, the first two months of spring, or when the sun is milder during the day.
- Cuttings: Treat the cut end of the cutting with lime to prevent fungal infections. Tie a plastic bag over the cutting to retain moisture. Plant the cuttings at a depth of 6-10 cm, angled at 15 degrees, and spaced about 20 cm apart to allow for growth.
- Water the cuttings every 2-3 days, ensuring they receive adequate sunlight and ventilation.
Care Techniques
Proper care techniques are essential for the plant’s healthy growth and flowering:
Moderate Watering: Bougainvillea is drought-tolerant, so avoid overwatering, which can lead to root rot. Water just enough to keep the soil moist.
Monitoring: Keep an eye on the plant’s growth and watch out for any signs of pest or disease infestation.
While bougainvillea is generally resistant to pests and diseases, issues may occasionally arise. If this happens, treat the plant with agricultural chemicals and regularly cut and treat the soil.
Regular Fertilization:
To encourage flowering, fertilize the plant every two months with a balanced NPK fertilizer (1:1:1 or 2:1:2). You can also use organic or slow-release fertilizers for optimal results.
