Hanging baskets typically contain a lightweight inert growing media (peat and/or green waste compost) with no inherent reserves of nutrients. Watering is often infrequent and the baskets can repeatedly cycle from very wet to very dry. With baskets being expensive to produce and maintain, and being very visible, it is especially important that they are fertilized well to keep them looking healthy and attractive throughout their life.
