Hibiscus flowering problem
I planted two small hibiscus plants three years ago, both placed in sunny spots with good drainage. They have grown well over the past few years becoming established but have never flowered. The garden gets regularly mulched although no direct feed given to the plants. Are they still quiet young, or is this a feeding issue. I am also wondering if they may not be getting enough sunlight as neighbouring shrubs are significantly larger, although adequate space was given at the point of planting.
