It is best to apply fertilizer when the soil is moist and then water lightly. This will help the fertilizer move into the root zone where it is available to the plants, rather than stay on top of the soil where it can be blown or washed away. Watch the weather. Avoid applying it immediately before a heavy rain system is predicted to arrive. Too much rain (or sprinkler water) will take the nutrients away from the lawn's root zone. Use the minimal amount of fertilizer necessary and apply it in small, frequent applications. An application of 2 pounds of fertilizer five times per year is better than 5 pounds of fertilizer twice a year. Calibrate your fertilizer spreader to be sure you know exactly how much material is being discharged in a given space. Follow instructions accompanying your spreader. When spreading fertilizer, cover ends of the lawn first, ten go back and forth across the rest of the lawn, using half of the recommended amount. Shut the spreader off before reaching the ends to avoik over-application. Apply the other half of the fertilizer going back and forth perpendicular to the first pattern. Dispose of fertilizer bags or containers in a safe and state-approved manner.
Hammering a nail close to the edge of a piece of a board may cause it to split. This problem can be solved by using the nail to open up the split, them filling the crack with glue. Wipe off any glue that runs over. Remove the nail, then clamp board as the glue dries. To avoid these splits in the future, use a drill to bore a pilot hold.
