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.
