Last fertilization

18 years ago

I still need to apply my high urea November ferilization. The directions on the fertilizer say to water it in after application. How important is it to water in this application? My irrigation system has been winterized for the year and I have over 10,000 sqft of lawn so watering it in would be pretty difficult. Should I just wait for rain to be in the forecast? Of course the problem with that is the weatherman isn't always right.

    Unless you have impending rain in your forecast, I believe I would drag out the oscillating sprinkler and drag in around the yard some. I can't remember anyone ever posting about burning up the lawn because of not watering in the fert, but with heavy dew this time of year I don't think I'd take that chance.

    Well neighbor, I'd do it Sunday, and hope for the best - because top growth has stopped already and average temps have been below 50 degrees for over 10 days now.

    Mon PM - 30% chance of rain
    Tue AM - 50% "
    Tue PM - 40% "
    Wed AM - 30% "
    Wed PM - 30% "
    Thur - 30% "

    If by Thursday it doesn't pan out, sprinkler time.

    You're not going to burn anything, putting urea down in what's going to be (plus or minus a week or two), the last chance before winter and/or really consistent cold. I've been doing it for years, just about now, the week before TGiving, and never watered it in. Nature does, or does not, and I've never worried about it. I'm in Mid Michigan, just north of you. Go ahead and put it down. But I wouldn't bother dragging hoses back out, mine are coiled for the season.

    Here's a link from another thread on here that has some thoughts on this topic:

    Garyinchicago,

    Actually I took my lawnmower to the leaves yesterday and still cut off about a quarter inch of grass after mowing a week ago Thursday; If my top growth has stopped it is in just the past few days. I am going to put the fertilizer down today and see what happens

    The need to water urea type fertilizer in applies to new grass plantings. The need to water in after application does not necessarily apply if its just a general application for its nitrogen content.

    I would think at this time, rain has fallen in recent days...and the ground is well enough moisturized so that the fertilizer is being taken down by it.

    At this time of year, the ground is moist enough that salts are unlikely to cause root damage. However, with moist leaf tissue, salts sticking for any prolonged period can cause leaf death. The concept of late fall fertilization requires that leaves are capable of photosynthesis to create root stores. That said, urea has a lower salt index as compared to chemical fertilizers, but still enough to cause burn. If applying winterizer without watering in, I think it is prudent to avoid doing so when the blades are wet and no rain is forcast.
