All plants require the proper nutrients in order to thrive. These nutrients are found in the soil in which they grow. The three major chemical compounds of soil are nitrogen (N), phosphorus (P) and potassium (K). Nitrogen helps plants develop strong leaves and healthy stems while phosphorus plays a vital role during the early stages of root development and early growth. Potassium promotes root vigor and disease resistance. Maintaining the proper balance of these ingredients is crucial for your plants survival. It is very important to test soil conditions for the correct Ph levels and much more. Cheers
