fertilise hibiscus that are looking in bad shape

I am not sure what the temperatures are like at the moment where you live, but it might be best to wait till spring before you fertilise your hibiscus. The soil will be a lot warmer then and more receptive to the fertiliser. You could, at the end of August, give your hibiscus a prune. They seem to respond well to a tidy up and this will encourage some new growth. You can apply a slow release fertiliser such as Yates Thrive Natural Roses & Flowers Pelletised Plant Food. It's enriched with Dynamic Lifter and has added nitrogen, phosphorus and potassium to give your flowering plants the right balance of nutrients for their growing needs.
