Homemade Gardenia Fertilizer
As an alternative to using pricey commercial type fertilizer, gardenias benefit from homemade fertilizer as well. These are just as effective.

Since they are rich in nitrogen, magnesium, and potassium, coffee grounds are oftentimes a more favorable homemade gardenia fertilizer. Coffee grounds are also very acidic in nature.
