I'm not that familiar with the Scott's Step program. What are in those two steps? Are there weed killers/preventers? Did you seed recently? What's the NPK of each of them?

Step 3 is Summer, 32-2-3 with grub and insect control.

Step 4 is Fall, 33-3-10.

Was considering throwing out some new seed, but would wait a month between seed and fertilizer. Which should I do first? There are only a few small bare spots. Most everything covered with something. Just that last summer seeded variety (and a few weeds) are now green, and growing well while the rest is getting a slow start.

If you have equal amounts of each and mix them, you'd end up with something that is 32.5-2.5-6.5 and would have 1/2 the amount of insect and grub killer. I don't know whether the insect and grub killer will be effective this time of year or not. If it is, I'm not sure whether it will be enough to kill since it'll be at half the concentration. Do you have insect and grub problems? If not, I wouldn't use the insect and grub control in the future. I may be mistaken, but I think it's bad for earthworms.

Spring is not as good a time to reseed as fall, because it doesn't give much time for the grass to establish before the heat of the summer. If you're going to seed in the spring, I think you should do it as early as conditions allow to give the grass as much time as possible to grow before summer hits.

I don't think seeding should have any effect on when you'd put down the fertilizer.

Thanks. Just wanted to be sure I wasn't going to do something crazy. Don't think I have a grub problem and don't wan't to hurt earth worms. Don't think there are many of those yet either. Just didn't want to hurt the lawn while not wasting the fertilizer. (It was given to me.)

Next year, when I'm sure the grass is holding good, I'll start on the weeds and such. Have a back hill to fix and brick walks/ decks to focus on this summer.

Thanks for your help!

I think I'd save the Step 3 until it's time, then use that with additional Step 3 to bring it to the proper usage (storage for a year shouldn't be too much of an issue, I shouldn't think). For right now, the Step 4 is just fine, though, and you needn't be very exact about the applications of that. I'd just buy enough Step 1 or leftover (and perhaps cheaper!) Step 4 to compensate.

The reason is that applying half the insecticide is like taking half your antibiotics...you're asking for trouble, if not for yourself right now, then down the line. Those insects, what few are up now, will have the weakest killed while the stronger, more resistant ones survive a dose that isn't quite killing.

They then breed with other survivors and their children have a greater tendency to be resistant to the insecticide. That's not a good thing as you'll need to use more in the future and still not reliably take them out.

Besides, have we learned nothing from 1950's sci-fi? Don't use the chemicals incorrectly or apply radioactive substances and nobody has to go clean up the giant ants in the storm sewers.

Good point morpheuspa. Should have thought of that myself as I'm always carrying on about doctors over prescribing anti-biotics! It would be awesome to have our house devoured by a 50' grub as long as no one got hurt. I would put on my best hill billy presentation for the news. :)

Thanks guys.
