Too much of a good thing can be bad for your plants
(Tampa, Florida, USA)
When a friend of mine helped me to transplant a small tree we found older soil with way too much fertilizer. It is really important to read and follow directions when using fertilizer.
Too little fertilizer won't help growth. But too much fertitilizer can burn the roots and stop growth.
Also, make sure to read labels of fertilizers to see what type of soil they should be used in and what types of planting they will help. Reading directions and following them will lead to a beautiful garden.
