Fertilizer Explained – Landscaping and Lawn Care Company

With all the rain over the last few months and now these hot temperatures, gardens are finally growing.   Help them along a bit with fertilzer chosen for your specific application.  So how do you know what to buy, and what do those letters on the bag mean?  Here’s a quick guide:

NPK stands for nitrogen, phosphorous and potassium or potash (made right here in Lima!).  Those three numbers on the bag are the amount of each of these chemicals found in the fertilizer.  If you want thick green foliage, choose a fertilizer with a high nitrogen content.  Phosphorous helps roots and flowers grow and develop, and potassium feeds the plant’s overall health.

Note that while a high nitrogen content will promote quick growth, the plant may grow too quickly and become weak and susceptible to disease.  There are plenty of other nutrients that are beneficial to plants – compost can provide many of these, and some worms added to your garden will help aerate your soil.  Healthy soil will lead to healthy plants.  Please use fertilizers according to the directions on the bag to keep run off from entering our streams and drinking water.  If you want more information or have any questions, feel free to give us a call at Blass Residential Services.
