using fertalizer to improve the health of your lawn

To start helping your lawn look its best, you could try to use a thatcher to pull up all compacted material that has been pushed down to the ground throughout the years.

Also, fertilizer never hurts. Putting down Turfbuilder plus crabgrass preventer in the early spring will help to make the lawn look nice. Also, in the Early Summer, you could apply Turfbuilder plus Broad Leaf Weed killer. In the Late Summer, you could apply Turfbuilder plus Insect killer, followed 3-4 weeks later by an application of Grub-Ex.  Finally, in the mid to late fall, put down Winterizer.

I would recommend using a drop style spreader to apply fertilizers because they are more accurate than a broadcast spreader.
