Depending on where you are applying a good, organic plant food to your lawn in the fall is a good idea, and how late is what is dependant on where you are. If you have mulch mowed the grass clippings back into the turf all summer then most likely you will not need more than about 1 pound of Nitrogen per 1,000 square feet this fall and that will provide your grass with what it needs to leap into growth next spring. Most turf grasses need about 2 pounds of N pre 1,000 Ft2 per year and recycling the clippings right back into the lawn can provide 1/2 of that. However, a good, reliable soil test is always a good idea.

Thanks,

I suppose a soil test now would be quite helpfull to see what has changed since the spring tests.

I'm convinced that 'winterization' is a term invented by Scott's to sell fertilizer so they can make their last boat payments. What Mother Nature does in the fall to winterize is to drop leaves and acorns. The leaves give some protection from hard rains and provide a more constant temperature and moisture level in the soil. The acorns give the squirrels something to bury.

If you had a soil test done last spring, that will provide you with any information you need to apply a plant food now.
