All you need to do is to mix liquid fertilizers with water and sprinkle it over the plants. Liquid fertilizers should be used bi weekly or once every 21 days for greater impact. Granular fertilizers: These fertilizers are added to the garden by using a spreader followed by the sprinkling of water. The advantage of using granular fertilizers is that you are well aware of the quantity of fertilizer that is being added to the lawn. One of the common techniques that are used by growers in different parts of the world is the Stale seed bed in which soil is cultivated and is left for about a week. When the seeds are germinated in the ground, there are increased chances for the growth of weeds that hampers the growth of the plants and eat up their nutrition. This is known as a spreader and is basically a tub, which is pushed all over the lawn, spreading the fertilizer or the weed killer evenly over the surface of the grass. The spreaders last a pretty long time, and if you want to add seeds to some areas of on your own, you can buy a spreader which has a rotating handle and can be held in the hand. Special Tip on Seeding a New Lawn Before you go out and purchase grass seed, you should make sure you are buying one that will grow in your area. You should also know if the grass you are buying is a cool season grass or a warm season grass. Warm season grasses do best in the southern states, while cool season grasses grow better in the northern states. In the chance that you do get rain, have your gutters set up so the water is diverted to your new lawn. If you are just starting a new lawn and preparing the soil, you should add organic matter that will aid in water retention. You should also probably think about sowing a grass seed that is draught resistant. If your soil test shows that the pH of your soil is 5.5 or lower, your soil is acidic. This means that magnesium, calcium and phosphorous are not readily available for your grass like they would be in a neutral soil. Acidic soil is commonly called “sour soil” because the soil’s organisms cease to work when the pH dips below 5.0.
