Have a large Hibiscus, looks very healthy but hasn't flowered this year. What should I do, please? Thanks Sheila

There could be a few reasons for lack of flowering including sunlight and water.
Generally the plants that appear lush and green have to much Nitrogen in the soil.
Adding a Phosphorous rich fertilizer such as Bone Meal will encourage blooming.
