Care Instructions for Pelargonium ‘Oldbury Duet’:
- Light: Pelargonium ‘Oldbury Duet’ thrives in full sun to partial shade. It prefers at least 6 hours of direct sunlight daily to promote vigorous blooming.
- Watering: This plant is drought-tolerant once established but performs best with regular watering. Allow the soil to dry out slightly between waterings to prevent root rot. Water thoroughly during prolonged dry periods.
- Soil: Well-drained soil is essential for Pelargonium ‘Oldbury Duet.’ It prefers a neutral to slightly acidic pH (6.0-7.0). Adding organic matter such as compost can improve soil fertility and drainage.

- Fertilization: Fertilize every 4-6 weeks during the growing season with a balanced fertilizer. Follow the manufacturer’s instructions for application rates.
- Pruning: Regular deadheading of faded flowers will promote continuous blooming. Pinching back the tips of the plants encourages bushier growth and more flower production. Prune about 1/4 to 1/2 inch (0.6 to 1.3 cm) above a set of leaves or a branch.
