Baptisia shrubs not blooming
Three years ago I planted two Baptisia australis shrubs and they have yet to bloom. They get at least 8 hrs. of sun daily. Bushes are in excellent condition. Could you give me any information as to why they have not bloomed? They are at least 4 ft. tall and wide.
It does take at least 3 years for the plants to become established and start to bloom.
Since your plants are just reaching that age I would be patient.
You could also add some Phosphorous to boost flower production. Bone Meal is a good way to do so, but I would recommend waiting until early spring to fertilize.
