how and when to prune diplodenas

Thank you for contacting Yates. 

If we are referring to pruning for Dipladenias, the best time is during winter when the plant is slow-growing. Once the temperature warms up, try feed the plant every 6-8 weeks with 'Yates Thrive Natural Roses & Flowers Organic Based Pelletised Plant Food' as a complete, soil-conditioning fertiliser for more prolific blooming and healthy plant growth.
