To achieve optimum growth and flower and fruit production all plants will require an application of fertiliser at some time or another in their life, whether it’s for a specific nutrient or a general boost throughout the growing season.
Even plants growing in their natural habitat have evolved to extract nutrients from composted leaves, rain or by products from animals. All fertilisers whether organic or inorganic have been produced to deliver nutrients to plants.
There are specific formulations that target deficiencies or needs of different plant groups and general-purpose fertilisers which deliver a broad range of nutrients for most plants.
Deciding what to use for which plants can be daunting and the product chosen may not be delivering the best results.
