How often should I fertilise mandevilla flowers?


Hi Tui, please can you advise how often to fertilise mandevilla flowers, and with which product?



Hi Tanya

Feed in late winter/early spring when new growth appears. Apply fertiliser again once flowering has finished or in late summer, early autumn. If planted in a frost prone area fertilise after the risk of frost has past as new growth stimulated by fertilising will not have hardened off and may get damaged by frost or cold. Use a fertiliser such as Tui NovaTec Premium as it is high in potassium which is what is required for healthy flowering plants and feed every three months. Supplement feeding with a liquid fertiliser such as Tui Seaweed and Fish.

Thanks, Tui Team.
