Fertilizer , any merchandise that adds nutrients to plants , may sound like an ideal addition to your collection of gardening products . But more often than not it is unneeded and sometimes detrimental . Over - fecundation is a common — and sometimes fatal — mistake ; too much of a right thing can become a unsound matter .
Adding Salts
Among the most plebeian issues with over - fertilization is fertilizer burn mark . Fertilizer often wreak by cater nutrients to the plant in the form of soluble salts . Although salts dismiss easy in water , too much salinity can not dissolve . Instead , the piss evaporates and the salinity stay in the soil , causing a major disruption in the makeup of the soil . saltiness can burn the tender , young roots — and sometimes unassailable , matured roots — of landscape trees , shrubs , perennial and vegetables . When the salt burn the roots off , the plant is unable to engulf pee and other nutrients from the soil . The lack of water often result in scorched - attend folio , stunted growing and plant dieback . plant food burn is more severe in drought - similar atmospheric condition . Too many saltiness can interpolate the pH of the grime , making nutrient unavailable to plants . atomic number 26 chlorosis and other issues may lead from neutered soil pH.
Boosting Growth
Boosting growth may sound good at first , and sometimes it is ; however , a big cost increase in emergence can also kill your industrial plant . This is peculiarly the suit with too much nitrogen . The nitrogen give a strong encouragement toward plant life increment , allowing your plant to grow longer stems and leaf . alas , the young , affectionate and underdeveloped base arrangement can not support the blossom of new maturation triggered by the fertilizer . This pitiful root social system will stunt the development of flowers and fruits .
Attracting Pests
Unsupported growth is n’t the only works killer result from a upsurge in development ; many insect and arthropod cuss — and sometimes mammalian plague — favor the tender , unseasoned growth of leave , buds and stems as fight to more matured piece of a plant . When your plant life starts pip off tender stems and leaf bud , more insects become attract to the plant and pop out feeding more voraciously . Aphids and mites are among those that choose to feed on the plushy , tender maturation of over - fertilize plant .
Consider This
Before applying fertiliser , throw away the impression that plants need it to pull round . Fertilizer is project to supply plant with nutrients that are lacking in your soil . Most plant do n’t demand any fertiliser at all if they are rout in healthy soil . Before applying fertiliser , learn a soil - examination kit from a reputable nursery or on-line diagnostics lab and perform a dirt test . These tests are designed to evidence you your soil pH and the amount of nutrients in the grunge . Only apply fertilizer if your soil mental test prove your soil is lack . Over - fecundation can wreak havoc on your natural ecosystem , peculiarly overutilization of N and phosphoric .
