Instead of taking your best guess at fertilizing, use soil testing to scientifically determine which minerals and nutrients are needed in your soil. Different plants require different nutrients, and your soil will change from year to year.
Several nutrients are absolutely essential for proper plant growth. Equally as important is the pH level. Midwest Labs soil testing lab will advise the proper fertilizer and or lime you need to use, and they will help you to not over-fertilize your plants. Over-fertilization:
1. is a waste of money,
2. can lead to burnt, overgrown plants with maturation problems
3. is bad for the environment.
Your soil testing results will report the pH level as well as levels of:
6. and magnesium.
