The best Bermuda grass fertilizers are those that contain as close to a 3 to 1 to 2 ratio of nitrogen, phosphorous and potassium as possible, such as Bradfield Organics Luscious Lawn & Garden. Other good fertilizers include Nitro Phos Super Turf, Southwest Premium Gold and Fertilome Green Maker.
In addition to the 3 to 1 to 2 ratio, the best Bermuda grass fertilizers also contain slow release nitrogen. The percentage of slow release nitrogen is normally listed next to the fertilizer's ratio.
The fertilizer should be applied to Bermuda grass in three applications in mid-spring, mid-summer and early fall. The general consensus on fertilizer application suggests 1.5 pounds of nitrogen for every 1,000 square feet. Calculate the amount of nitrogen in a bag of fertilizer by multiplying the first number in the fertilizer's ratio by the total weight of the bag.
