when is the best time to add ferilizer to my lawn?

Basically this is correct,but two points1.Tip the grass as you suggest.then lightly rake it,using a wire rake if possible.

This will remove the thatch of moss,dead grass etc;which builds up over winter.

2.Assuming this is an established lawn,apply a "Weed and Feed" fertilizer,preferably when rain is due.Should this be a new lawn,a slow release nitrogenous fertilizer would be best.

If you are talking about just fertilizing, than it should be done in spring, summer and fall.

There are different combos of the ingredients for each season which would best researched on the internet.

You can also buy these fertilizers mixed with weed controls. Good luck.

most weed and feed products are mainly for the control of broadleaf weeds and contain 2,4-D. Unless it is already regularly above 65 degrees in Georgia at night, it is too early to treat with that product. It's probably a good time to put down a pre-emergent for control of grassy summer annual weeds, and a lot of those contain some fertilizer.

Especially for the first mow,wait a week for the blades of grass to recover from the mowing.the rest of the year,3 or 4 days.

Fertilize when the temperatures warm up and the grass starts to grow. You can fertilize the same day if you want.
