Next, you will need a lawn roller. If you do not have one, you can rent one at a rental agency. Rake the area again. Apply a light application of fertilizer, again, to the surface. If you are starting a new lawn with seed, now is the time to spread the seed. Likewise, if you are starting a new lawn with sod, now is the time to install the sod. If you are planting a new lawn with cool season grasses, it is best to sow your seed in the early fall. During this time the ground still has enough heat to germinate the seed. You can sow your cool season grass in the spring, but keep in mind that it will not have as much time to establish itself before the hot weather season. Nitrogen is good for lawns because it can really help to green up a dull yard. If you already have a mature, existing lawn, you will probably not need a high percent of nitrogen in your fertilizer. The second number that is listed on fertilizer bags is phosphate. Phosphate helps the grass seed to germinate and it promotes root health. If your grass starts to take on a gray color, it is telling you that it is not getting the water it needs. A quick way to see if your lawn is getting enough water is to use a knife or screwdriver to dig into the soil. The dirt should be damp to a depth of six inches. Once your new lawn has passed the two week time period, you can reduce watering to two or three times per week. If you do not want to fool with locating a lab that will test your soil, simply purchase a soil testing kit and do it yourself. Soil tests will tell you what amendments should be added to your soil prior to planting. Whether you plant to sow seed, install sod or plant sprigs and plugs, you should have the growing area tilled. Carts are used in lawns and gardens to carry heavy objects and waste grass from one place to another. Carts are little expensive than other equipment that are used on lawns. String trimmers are also used as major equipment in gardens that are very sleek in design and are quite long. Blowers are used to maintain the lawns and remove all the dust and non-required particles in it.
