At its most basic, biology is the study of life. Exploring the function, development, and growth of living systems from the human body to global climate, the chief aim of biology is to understand processes of evolution and the genes and cells that act as building blocks in our physical world.
Fertilizer. Generally, for gardenia, acidic fertilizers are used. You can find special fertilizer for gardenia in any garden store or online. You can also fertilize it with azalea fertilizer. Application of Epsom salt once in a month during the growing season is also essential for the proper growth of gardenia. Acidic soil is the key to growing gardenias successfully.
Mulch plants with pine straw or chopped leaves. Gardenias need acid soil with a pH between 5 and 6.5. Feed them when they are actively growing with a fertilizer made for acid-loving plants (such as azaleas and camellias). Or you can use fish emulsion or blood meal. If your plant's leaves begin to yellow, spray with chelated iron.
