Lawn Winterization.
How a lawn looks good in March.

The last feeding, the last cut and the leaves off before the snow. That is what a lawn that looks good in March is built on, and the feeding part has a legal deadline only a licensed applicator can use.

Lawn Winterization

Lawn winterization in Bernardsville, Mendham and Chester

Winter is not when the lawn dies. It is when the roots do their quietest and most important growing, if they were fed. The winterizer feeding is the most valuable application of the whole year.

By late fall the grass has stopped growing on top, but the roots keep working until the ground freezes. A feeding put down in that window goes almost entirely into root growth and stored energy. That stored energy is what greens the lawn up in March, weeks before the neighbors, and what carries it through the summer stress that follows. Skip it and the lawn starts spring from zero.

What winterization includes

  • Winterizer feeding, high potassium slow release, before the December 1 cutoff
  • Final cut at a shorter height so the grass does not mat
  • Leaves off the lawn before the first snow
  • Lime application if the soil test calls for it, fall is the best time

The December 1 rule

New Jersey’s fertilizer law is strict about timing. Homeowners cannot apply nitrogen or phosphorus to a lawn after November 15, and nothing goes down until March 1. A licensed professional applicator has until December 1. Those two extra weeks are exactly when the winterizer does the most good, because the top growth has stopped and everything goes to the roots. It is the one feeding a homeowner physically cannot do at the right time, and no other lawn company around here bothers to mention it. Botti Home Services is licensed for it.

Leaves are not mulch

A layer of oak leaves left on the lawn through winter smothers the grass, holds moisture against it and breeds snow mold. Every Somerset Hills property has oaks. The final cleanup takes the leaves off before the first snow so the lawn goes into winter breathing. The last cut goes a notch shorter than summer height, which keeps matting down and lets light reach the crown.

Where it fits

Winterization is the last lawn service of the season. It is at its best after a fall of aeration and seeding, because new grass with a winterizer behind it goes into spring with roots. If you only do one thing for the lawn all year, this is the one.

We check the lawn

Fall condition, leaf cover, whether lime is due. Number by text.

Final cut and cleanup

Quick answers.

When should a lawn be winterized in NJ?

Late October through the end of November. The feeding has to be down by December 1 for a licensed applicator, November 15 for a homeowner.

What is a winterizer fertilizer?

A slow release feeding heavy on potassium and nitrogen that goes to the roots rather than top growth, because the top has stopped growing.

Should leaves be left on the lawn?

Not a thick layer. A few chopped by the mower are fine. A blanket of oak leaves smothers grass and causes snow mold.

How short should the last cut be?

A notch shorter than summer, around two and a half inches, so it does not mat under snow.
