Hi this is Kyle from DoMyOwn.com.
Every bag of fertilizer has three numbers on it. These three numbers
represent the macro-nutrients: Nitrogen, Phosphorus, and Potassium. These are the NPK ratio. The percentage of nitrogen phosphorus, and potassium is usually
listed on the bag, so if you have a 20-pound bag of fertilizer and your first
number is 20 for nitrogen, you can take that 20 and multiply it by 0.24 to
get 4.8 pounds of nitrogen in your bag of fertilizer. So those three numbers…
what do they mean? Up, down, and all around is a great way of remembering what those
three numbers do. Nitrogen, up, helps promote healthy leaf growth and green up
of your lawn. Phosphorus, down, helps plants roots grow and strengthen.
Potassium, all around, helps the overall growth of the plant, keeping them healthy
and balanced. To determine the nutrients through your lawn needs, you need to
analyze your soil. You can do this one of two ways:
you can take a soil sample to your local extension or co-op office, or you can do
an at-home soil analysis kit. If you need help doing your soil sample, we have
videos online that can help you with that. Once you get your soil analysis
back, this will help you pinpoint the nutrients that you need for your lawn.
The tests can also help you identify micronutrients or amendments such as
lime and sulfur, that can help with the pH of your lawn. Once you know this, you
can pick out the proper fertilizer that matches your lawn’s needs. Your fertilizer
application timing depend on the type of grass that you have – cool season grasses such as Kentucky bluegrass, ryegrass, and fescue should be fertilized in the
spring from March to May when lawn comes back from dormancy, and again in the
beginning of Fall from September to November.
You should fertilize cool season grasses throughout the year, depending on the
needs of your lawn. You shouldn’t fertilize school season
grasses in the warmest summer months, because those grasses are dormant during the summer. Warm season grasses such as Bermuda, St. Augustine, and centipede need to be fertilized every six to eight weeks, starting at the beginning of March
and spring through the end of summer. as late as September depending on the
soil temperature. Depending on your preferences, fertilizer comes in granular and liquid form. Proper fertilization of your lawn will
help keep it green, healthy, and free from weeds and disease. If you liked this
