And since a dense stand of grass is one of the best ways of keeping down weeds, lawns should be given every opportunity to grow with vigor, fertilizer is a key requirement.
There are a number of very good lawn fertilizers, these should be used according to recommendations of the manufacturer. A good standard rule for the amount to use is to apply one pound of actual nitrogen for each thousand square feet of lawn surface. The first number in a fertilizer formula refers to the per cent of nitrogen. Divide this number into 100 and the answer will be the number of pounds of that fertilizer to use for each one thousand feet of lawn surface.
Some turf specialists recommend a combination of fifty per cent organic and fifty per cent inorganic fertilizer. The inorganic type will become available to the grass at temperatures below 70 degrees; the organic at temperatures above 70 degrees. Thus in early spring you will have a fertilizer that will be available to the grass over a greater range of temperature conditions.
