The Best Southern Lawn Fertilizers Fertilizers

These are the best fertilizers for southern lawns. They use quality ingredients and are much better than the other fertilizers on the market.

Best Fertilizers for Southern Lawns

Nitrogen is very important in the growth and maintenance of a healthy lawn. But too much nitrogen can destroy it. LawnStar has the perfect blend of nitrogen, phosphate and potassium. It also has accelerated and maintenance growth aspects to feed your lawn initially and support it for the long haul. It comes in liquid form. It also comes with an attachable spray nozzle to help apply the product. When combined with water from your water hose, Lawn Start promotes a healthy yard.

Professionals use Andersons PGF Complete to green up golf courses. It comes in tiny granule form. These small granules give a steady, gradual delivery of nutrients and minerals to your grass. It has the building block of four different types of nitrogen as well as phosphate and potash. The perfect harmony of nutrients gets a further boost from minerals such as copper, iron and zinc. For those who love to apply humus (a compound made from plant compost) to their gorgeous grasses, Andersons PGF Complete already has that ingredient in it. Humic adds certain microbes to your soil to help your lawn reach its full potential.

The “S” in this turf builder stands for “South!” Meaning that it is specifically made for those beautiful blades of grass in the southern states. The common dollar weed is powerless before it. Clover and other undesirable plants don’t stand a chance as well. Scotts also builds up the lawn and takes the surplus water from the soil to help prevent the weeds’ growth in the first place. If your weeds are stubborn and don’t want to disappear, a second application may be needed. It also creates a strong root-network to protect the grass from those bouts of extremely hot weather. Unfortunately, if you have Bermuda grass, this is not the turf feeder for you. It only works on certain grasses such as carpet, centipede and St. Augustine.

The next nutriment in this series of mini-reviews is Simple Lawn Solutions Superior Nitrogen & Potash. If you test your grass and find that it lacks nitrogen and potassium, then this is the solution for you! Simple Lawn Solutions use basic, simple ingredients. Being in liquid form makes it easy to disperse. It is safe to use around children and pets. Any type of lawn can benefit from its use. Many customers have found that one application made their grass green.

The last of the mini-reviews is another Scotts company innovation. This plant food is also geared towards the particular needs of southern lawns. Unlike some other reviews of top dressings for your yard, this product is safe to walk upon right after applying it to the grass. It also helps your lawn drink in nourishment. Your grassy plot has a better chance of staying healthy during dry spells. You can use Scotts Turf Builder on any type of grass. Use it every six to eight weeks in most areas for the best results.

How to Produce a Beautiful Southern Lawn

In general, there are three different types of grass that compose a Southern Lawn: Bermuda grass, St. Augustine grass, and Centipede grass. Make sure not just choose any fertilizer with grass on the product image as this definitely will not be the best fertilizer for your lawn. Also do not choose simply on price. 

What type of grass do you have?

To pinpoint the best fertilizer for a southern lawn, the first task at hand is to try to identify what type of grass you have. Typically in the south and in warmer climates, a couple different species of grass tend to flourish: Bermuda grass, St. Augustine grass, and Centipede grass.

Bermuda Grass

Bermuda grass tends to have sharp, pointed blades that are about 0.125 inches wide and they have a deep bluish green color. It forms a lush, dense turf.

Bermuda Grass

St. Augustine Grass

St. Augustine grass has coarse blades and has a dark green color. It can be grown in partially shaded areas.

St. Augustine grass

Centipede Grass

Centipede grass has coarse boat-shaped blades and tends to have a light green color.

Centipede grass

N-P-K Ratio

If you have St. Augustine or Bermuda grass, you will want an N-P-K ratio around 4:1:2 and if you have Centipede grass, you will generally want an N-P-K ratio of around 1:0:1. This is because Centipede grass does not need as much phosphorus to flourish.

Do not over fertilize your grass!

It is vital that you do not over fertilize your lawn. This is why having the wrong NPK ratio (too much phosphorus) for your lawn (ex: centipede grass) can be potentially deleterious. Too much nutrients will make your lawn a breeding ground for pests and will also cause your grass’s roots to be in a diseased state. Choose the right fertilizer and also make sure to follow the product instructions to make sure you are not over feeding your lawn.

Bottom Line

Again, I recommend buying Simple Lawn’s Fertilizer. Don’t make the mistake of buy any average fertilizer at your local gardening store. Many of them will simply not produce the same results. You cannot go wrong with any of the fertilizers above.
