    I used a Round up type product to attempt to kill some weeds but it left some big yellow holes in my lawn where it killed the grass as well as the weed. In hind sight I shouldn't have done this.... to make matters worse my lawn care company came & applied a pre-emergent the next day - going forward I wont be doing anything weed related since I'm paying these guys to do it for me .....

    What i did was DUG OUT the areas of dead grass & removed about 2-3 inches of soil underneath... then I added some Scotts Miracle grow soil in the hole & mixed the seed in. This soil says it Feeds for 3 months. Fertilizer Analysis is 15-5-10 .... this was last friday (3/26/2010)

    on Sunday i had some extra fertilizer in granule form that I sprinkled lightly on top of the areas that I seeded. this was some extra Vigoro plant food that says it for Azalea, camellia, & Rhododendron 10-8-8.

    I only sprinkled that on top to try to speed up germination and get this seed to sprout plus I was trying to counterattack the barricade pre-emergent that my lawn care company put down...

    Are my seeds at risk with this much fertilizer..? Is this TOO MUCH fertilizer on the new seed??
    Should I go and sweep off that granule fertilizer i used since the Scotts Miracle grow soil I used already has fertilizer in it?

    You need to learn to use the right product for the puropse or just leave it up to the pros. It's almost impossible to apply the right amount of fertilizer...I'm sure this is serious to you but sounds like a classic comedy of errors from my end.

    I suspect that the soil only had a small amount of fertilizer included--if it was actually 15-0-5 there would n't be any room for the soil. No problem--I think. And the Vigoro fert-I cannot tell how much you sprinkled on by hand--I can't guess about this. But I suspect you will be OK. What kind of grass do you have--what kind of seed did you use? For all new seed, water it every day for 30 days.

    sounds a little overkill, however the only way to know is to see if the grass grows, make sure you keep the newly seeded areas watered, i suspect it will be ok....worst case scenerio...it wont grow.

    What is bad on top of that, is none of these fertilizer analysis are real conducive to achieving the goal you're trying to achieve - to grow new grass. I higher phos. fert. would have been a much more suitable fert. for your goal. Do NOT go and put anymore fert. on it at this time, though. Just keep it damp....you should be fine.

    Mark the areas with stakes and string so your Pro will know it's seeded. Give them a call so they know you did something and ask them to treat it accordingly. Leave it alone otherwise. You water and mow, let the Pro's do the rest and it should turn out just fine.

    thanks for all your input..

    to all who asked: i used Lesco transition blend fesce seed (which is one of the best seeds out ; a close second is Rebel Elite...just my 2cents) I'm hoping it comes back strong by the end of april so it can have a chance before the summer months kick in....

    Two things concern me, #1 The pre-emergent may not allow your seed to sprout. & #2 You seem to be impatient. Fescue has a fairly long germination time compared to rye grass. If you planted a mix, the first grass you see will be the rye. If you mixed this seed with the soil as you said, that may also be a problem for you. Grass seed should be sown a max of about 1/4 inch deep. we usually spread it on the surface, and rake over with a leaf rake, and roll, that's it, good soil contact that's the key.

    One more small point, the virogro you used is for acid soil loving plants (Azalea, Roddies) grass likes a more neutral soil. Sorry to say, but lots of mistakes here. I suggest you go to the home center near you and get a Scotts or Ortho Lawn care book.

    PS: Fescue germination 10-21 days Maturity 4-8 months
