Can anyone recommend the best feed to keep a hibiscus flowering. An indoors tropical that has 75 degrees in summer and 70 degrees in winter, and lots of light. Advice on root pruning and also branch pruning would help too. Where can one get the food? Thanks.
They like rich soil, but choose a fertilizer with low phosphorus, rich in nitrogen and high potassium. Give regular dilute feedings. Bloom food fertilizers are rich in phosphorus and will not work well with Hibiscus.
