    Front Lawn

    I've got a lawn that was primarily fescue and that was neglected for a year (because of travel for business). This year I'm around a lot more and I want to get this thing back on track. We've put down pre-emergents about a month ago and the company I'm working with scheduled to have the yard core aerated on April 18th. My goal is to plant bermuda across the whole yard and take over the fescue with time. I don't want the hassle of trying to keep a fescue lawn alive in full sun in South Carolina. So, I'm wondering what my strategy should be from here.

    I understand that the soil needs to be really warm before I plant anymore bermuda. Should I have the turf maintenance company wait until later? Or will it be ok to wait and plant the bermuda a while after the core aeration has taken place.

    Also, I've got some dips in the yard. So, I was planning on getting some sand and filling in those areas as well as doing some top dressing along with the seeding.

    In my side yard (pictured). There has really not ever been grass. There I'm wondering if core aereation, topdressing, broadcasting the seed would be the way to go. The bermuda did begin growing last year, I'm thinking it may begin taking over.

    Bermuda is not suited to shade (in case you have any shade problems). It may be best to kill the fescue so that you will not have a mixture. The pre emergent applied for crabgrass any prevent any seed from germinating. Perhaps the Bermuda will spread by itself. Of course, you can always help it along by planting small sprigs in thin areas. Better quality types do not produce seed. But I am up north--local advice is better.

    the pre-emergents were put down almost a month ago, and i was thinking about waiting another month to sew the bermuda. Do you think that would be enough time to wait?

    I am also in the north, so I haven't had experience with warm-season grasses but here is my experience with seeding after pre-emergent.

    I actually got a 50/50 mixture of KBG/Rye to germinate and fill in about 4 weeks (late April) after pre-emergent was put down (granular form in late March). Filled in quite nicely actually...I was surprised. However, I had to baby the crap out of the spots I seeded because the temps were turning warmer and wind this time of year is stronger in Illinois.

    I know it's hard to wait, but Fall is BY FAR the best time to do all of these things. Even in South Carolina the temps are cooling a bit. But, if you have to do it now I would double aerate and overseed. Much of the seed will get into the holes created by the aeration. Spend the extra loot and get a GOOD quality seed that will be more drought hearty and will have a slightly higher germination rate. It's my experience that spending the extra money will result in much less frustration! Good luck!

    Thanks for the reply. I'm hoping that I can have some success getting the bermuda to germinate some this year. What's tough is that bermuda germinates best when it's warm (down here in SC, late may / early june is the best time to sew it). The problem is that the weeds come in early spring and the easiest thing is to put herbicide down which is what the turf management company did to eliminate the weeds. It's kind of a catch-22

    I'm thinking that next year I'll just spot treat all of the weeds with round up until I can put out a lot of seed early summer. I'm planning on aerating in about 2 weeks, overseeding late may, then watering and fertilizing the rest of the summer. I'm hoping the bermuda will just begin to run across the lawn.

    Wait until late May (as stated) depending on your pre-em there is a stated time frame before seeding. By looking at the pics it looks like some animals may be using it as a restroom (dark green patches) of course that is never good. Also get a soil test, determine shade times, check for various insects. (chinch bugs, nematodes, mole crickets) oh man Bermuda can go forever with the problems. Shoot me a pm and I can better communicate with you and get a better description as to where you are in SC and what you are dealing with.

    I've figured out my game plan. I'm going to hold off in the spring on aerating. Instead I'm going to kill off all the fescue on the other half of my lawn, then till up the soil where the fescue was once it's dead. Then I'll sew in my bermuda there.

    For the side yard. I'm just going to kill everything on that side, and till that up and clear all of that old mess out. A lot of rocks weeds, just junk. Then I'll sew that entire side lawn with bermuda. I've got enough time now where I can kill and clear all that I don't want, and seed the first week of june.

    This will require more work, and an unsightly lawn for a couple weeks while the old fescue is dying. Hopefully this was, I can begin to establish the kind of lawn I need instead of turning it into a 2 year gradual process.

    On a side note? What would be a good grass to mix in with the bermuda for shady areas? I've only got a couple areas (maybe 2-3% of the total area). Would it be best to put out a little fescue in those areas in the fall? I'm planning on overseeding with ryegrass eventually. So maybe that will be the best bet to have in the shady areas. Suggestions?

    How much sunlight does it get? Zoysia is good St Augustine is the best. There is a strand of St. Augustine that will be good for your area upstate. Haven't forogt about your message just extremely busy and I saw the email this morning.

    Pull a soil sample first before doing anything!

    Just sent off my soil sample today. Results will be back in 2 weeks. Just applied Eraser to the side of the yard with all the fescue. The timing will hopefully be just right. I'm giving the grass 2 weeks to die. Then I'll have a week or so to clean everything out and amend the soil.

    Should I till up and rake out the existing bermuda (200 sq. ft. section in the first picture nearest to the driveway) and reseed it all together for a more consistent look?
