How long??

18 years ago

Hi all, quick question here. I have started a new lawn in my backyard using TTTF blend and need to know how long to wait to fertilize and what best to use.

I tilled the whole backyard and raked in scotts starter fertilizer, then applied seed and raked some more, then mulched and watered. Now i am seeing some sprigs and I don't want to fertilize too early and ruin all my work. I will post pics and keep you updated as I am sure that this is not the last time I might need some advice

    Welcome to the lawns forum. I see you have been on Gardenweb for a couple years but if you had been a regular reader of the lawns forum, you would not have done most of what you did. I'm afraid you will have a real mess by the 4th of July.

    If I inherited a lawn in this condition I would let it grow and grow up to 4 inches or more and mow it at the mower's highest setting. I would not consider more fertilizer until after mowing real grass for the second or third time. I would also plan to lose almost all the new grass to the summer heat and have a 90% crabgrass lawn until September. Then after the summer heat breaks, you can redo the lawn again with much better technique and results.

    You might be able to recover somewhat at this point by scattering Kentucky bluegrass seed. Still you have the summer heat to deal with, but you need to be in the panic mode and try anything. The TTTF you planted, using the techniques you used, will come in extremely unevenly. Since TTTF does not spread you will have large bare spots. The Kentucky bluegrass will spread and fill in between the fescue plants.

    If you decide to do this, spread the KBG seed randomly and roll the seed down with a water fillable roller. Don't worry about your new seedlings. Don't rake. Don't mulch. Don't fertilize. Just roll it down and water for 10 minutes, three times per day, for 3 more weeks. KBG takes longer to sprout than most other grasses. What might save you from all the weeds is the KBG when mowed at the mower's highest setting.

    Sorry to have offended anybody that certainly was not my intentions.

    A little background here. We bought this house in Oct. of 06 and the backyard was all vegetable garden. We weren't able to clean it up until spring. Spring comes and we plant some sun/shade mix from a local farm store. It got taken over by creeping charlie.
    Then we built a garage in the backyard late in the summer into fall. With all the activity in the backyard we decided to wait until spring to plant grass.

    I'm probably wrong on the type of seed we got, my wife purchased it while I was at work and that is what she told me it was, but it came highly recommended locally and it appears it is a blend of grass (follow link please)

    Again I apologize for my ignorance and I am not trying to offend anybody.

    I don't think you offended anybody. David was just trying to prepare you for what you're likely to see. Central IL gets too hot in the summer for grass that was seeded in the spring. If you seed in the fall, the grass has more time to get established before the summer heat hits, so more grass lives through the summer.

    According to the brochure you linked, the mix you bought has rye and KBG. The rye will sprout fast, but it is especially susceptible to heat problems and doesn't spread. The KBG will take longer to sprout, but is better adapted to heat than the rye is. It will also spread to fill in bare spots.

    The problem with raking after seeding is that it can redistribute the seed and end up concentrating it instead of having it spread throughout.

    Depending on how much grass makes it through the summer, you may end up needed to seed again in the fall.
