How To Encourage Bottlebrush Tree Flowers

Hello. In the link below, it states to use a balanced fertilizer. It goes on to state, “To promote flowering, use a product higher in fertilizer a few times throughout the summer.” I am thinking it meant a specific fertilizer element. Can you please advise what higher element throughout the summer would help with flowering? Thanks so much. https://www.gardeningknowhow.com/ornamental/shrubs/bottlebrush/growing-bottlebrush-plants.htm

It is supposed to say phosphorous, but another article says not to overfertilize. Adding phosphorous through bonemeal is a way to add phosphorous organically and lightly.
