This Past Napa Summer My 2 Gardenia Bushes Had Not Gotten Many Blossoms. Fertilized With Sea Acid Based

Question

Max sea acid fertilizer. Could the heavy rains for last winter have affected the blooms?

Answer 1

I suspect that the soil is too acidic, not allowing proper intake of phosphorus and potassium. This could affect blooming. Acidic fertilizers should be applied quarterly, or every three or four months. Regular fertilizers should be used in between. Testing your soils can confirm.
