Lawn Refurb part 3

19 years ago

Today is Day 17 of my KGB over seeding and killing of parts of my existing lawn project . Below are the pictures as of today.

I have a few questions on the spots that have not germinated as well as others.

KGB mixture: Midnight, bedazzled and prosperity

1 . Should I put down some more seed in the bare spots or continue to wait?

2. Is it too early to cut the over seeded sections? I would do this next weekend and would leave the big spots where I killed the lawn for a few more weeks.

3. IÂve been watering 3 times per day for 13 minutes each zone. Tomorrow I will change to once per day for 15-20 minutes per zone. Is this ok?

4. Should I be thinking about fall fertilizer?

5. Lesco notified me that my soil test results are in. I have to pay them before they will disclose the details. I did get them to tell me the soil PHÂ..it was 7.5. Suggestions?

    That's looking extremely good! Even the patchy areas have sprout and it's coming in beautifully!

    1) Under normal circumstances, I'd say wait but you're really close to being out of time (if not slightly over the line already). Seed now, but lightly. Call it 1 lb/K ft.

    2) Technically, yes, but if it's heading over 3" it's time to mow it. If you must, just be extremely careful. If it's under 3" wait.

    3) Wait another week. Day 17 means that you're not completely sprouted just yet, even in areas that already seem full.

    4) Not until October 1 at the absolute minimum. If you used starter fertilizer, that's working away happily.

    5) Although a touch high, it's not awful. Ignore it for right now and correct with sulphur in spring to avoid shocking the new little sprouts. Once you get the results, post them.

    "Ignore it for right now and correct with sulphur in spring to avoid shocking the new little sprouts. "

    Trying to lower pH with a surface application of sulfur isn't likely to help very much. Sulfur does the most good if it's worked into the soil. When it's applied on top, too much goes into the atmosphere instead of changing into sulfurous acid.

    I would add organic matter instead. It'll help bring the pH toward neutral and will also act as a buffer. I wouldn't worry about it too much unless you're seeing signs of chlorosis.

    What is going on with those patches with the discolored (orange/yellow) seedlings? That looks like disease. Make sure it's not too wet in those areas. Also, it looks like some areas are seeded way too heavily. Be on the lookout for disease in those areas. If growth in dense areas stalls, I would recommend thinning those areas out with a Turf Hound core aerator.

    Are you refering to the the bald patches with new grass or the main lawn that was over seeded?

    The orange and yellow stuff is the dead grass I killed 4 weeks ago. The new grass is growing right beside and through it

    My mistake. I thought the orange/yellow were the new seedlings.

    I would agree with the above posters regarding adding organic material and holding off on sulfur for now. I've done both and my pH is slowly coming down over the years. If i were you, I'd pay Lesco and get the rest of your report...not over $15 I'm assuming.

    Well its been 36 days since I over seed some areas and completely seed over other areas that I killed with road-up

    I'm concerned with a few area and would love some advice on what to do. Will these areas fill in? Do I need to put down some more fertilizer?

    The last picture concerns me the most (above) I have several areas where the Grass seed came up over 3-4 weeks ago grew one inch and stop----what up with that. Other areas it grew 3-4 inches already and its been cut once.

    Below is my soil report perhaps this will help.

    Please advise me on the best way to proceed

    thanks in advance

    Your soil test looks fine. Apply a winterizing fertilizer around November 15. You already know not to apply lime. Your bare or thin spots will mostly fill in. If you have any seed left, you could dormant seed in January and / or Spring seed in April. You have done a great job and the results will be spectacular next June. You may want to consider organic lawn care if you want the very best performance from your lawn. Bill Hill

    thanks....I really hope everything fills in though!

    WHy is that some of the little grasses dont grow as quivkly as other ones?

    Looking good!

    Why is that some of the little grasses dont grow as quickly as other ones?

    It could just be the different cultivators used, or maybe the soil in certain area's is not as good. I have noticed that were I had a couple of small flower beds the new grass is coming in slower.

    If you are planning on using a winterizer on November 15, you can hit it with another shot of starter now.

    That's looking great! Using the leaves as a size comparison, those small holes will be filled in by next June with no problems.

    I also have some cultivars outgrowing other ones, and some grass that's growing...but not as fast. As time goes on and the lawn matures a bit, that's evening out. I let it go a week last time before I mowed and it was pretty even at that point.
