Relax guy, no problem Mon. You got new sod laid late in the season, you are going to have weeds so get use to it. Personally I would not worry about the Poa, but if it irritates you spray everything green with Round Up. Just make sure the Bermuda is dormant. In the meantime relax until the end of February. Last week of February or first week of March Apply a product called AMAZE. It is a long half life Pre-Emergence herbicide. Water it in and relax for a few of weeks. Once you are certain all chances of frost have past, get the lawn mower out and scalp the lawn down. I do not mean down to dirt, but enough to get all the dormant brown grass blades cut. Rake up all the debris and relax again for a few weeks until the weather warms up. Once you see some green sprigs of Bermuda growing after it starts to warm up, apply your first fertilizer application using a balanced fertilizer. Go to your local Home Depot and buy some Lesco 20-5-10 or 15-5-10 to do the job. Apply at the proper rate of 5 pounds per 1000/ft2 and water it in. From that point on find the BERMUDA BIBLE and follow the directions and RELAX.

Looks like seedlings. In other words, not spreading but instead seeds are sprouting. If a reasonable amount, suggest you hand weed now.

This reviewed published scientific paper confirmed the usefulness of heavy plastic mulches against Bermuda Grass, and found some organic mulches that were also effective. http://hortsci.ashspublications.org/content/43/3/795.full From the abstract: "Therefore, a 2-year study was conducted under 15-year-old mandarin trees to compare the effects of rice straw mulch, cattail mulch, black plastic mulch, hand hoeing, cultivation, glyphosate, and unweeded control treatments on weed control, fruit yield, and fruit quality. The greatest control (94%–100%) of weeds occurred with the plastic mulch (200 or 150 μm) and three mulch layers of rice straw or cattail. Covering soil with cattail or rice straw mulch (two layers) gave 85% to 98% control of weeds. Uncontrolled weeds in the weedy control caused significant reduction in yield and fruit quality and decreased the yield/tree by 62% compared with hand hoe treatment. Plastic mulches of 200 and 150 μm, cattail (Cyprus articulatus L.) mulch (two or three layers) and two mulch layers of rice (Oryza sativa L.) straw treatments significantly increased the fruit yield/tree by 24%, 18%, 20%, 11%, and 12% more than cultivation treatment, respectively, without significant differences among these superior treatments. Soil mulching with three layers of rice straw, cultivation, glyphosate, and 80-μm plastic mulch treatments caused a significant reduction in weed density and weed biomass, but gave lower yield than superior treatments. Which weeds were in the experiment? " The major grass weeds present on the experimental site were bermudagrass [Cynodon dactylon (L.) Pers.], barnyardgrass [Echinochloa colonum (L.) Link], torpedo grass (Panicum repens L.), and sandbur (Cenchrus pennisetiformis, Hochst. & Steud.) as a grass, and redroot pigweed (Amaranthus retroflexus L.), common purslane (Portulaca oleracea L.), and petty spurge (Euphorbia peplus L.) as broadleaf weeds."

I live in North georgia near dalton I would say removing the trees was the most successful thing.Its probaly something most people wouldnt have done, being that they was so close to the house . I havent completely blocked bermuda from the beds but have a technique that seems to be working pretty good..The beds in the middle/back where the green spiral trees(thujas) are, I used a step edger and edged both sides and went pretty deep.Probaly 4-5 inches.The bermuda still crawls in there but being so deep it never grabs/roots..I take my weedeater every two weeks and edge it by turning it upside down and it cleans it up nicely.I can let it go for 3-4 weeks and have some really nice sprigs to plant somewhere else.I got one more spot in the front I am currently sprigging and I will have my whole yard,front back and side 100 % bermuda.The bed closest to the camera I am using monkey grass as a border and its really doing great also..All the monkey grass was divided .I would take 1 big clump and make 5-8 smaller plants..The monkey grass was divided a year part.Thats why some plants are bigger than the others..The smaller monkey grass plants, the bermuda will creep through in that area but not to bad. So far this year I have used a 10-10-10 and miloganite(used these together as a cocktail) as my first fertilizer when the bermuda was about 75% green..6 weeks later I applied a 45-0-0, I am about to apply a 34-0-0, this weekend. As far as the leveling goes I do have alot of uneven spots.I did do some leveling.Like the stumps, I removed all the stump material and added dirt/compost in those holes..I do notice I have some dips in some of the areas where stumps was removed , but nothing to bad..One of the reasons my bermuda looks so good is because I mow my bermuda really high..Been doing it this way the last 3 years and REALLY happy with the results as you can see by the picture..Mowing high I can get away with unlevel spots without creating scalp marks..I also think that mowing high has really contributed to all the coverage ive been getting.The back yard filled in so FAST! Current mowing height is 3 1/2 inches,I will be at 4 by September. I think mowing low is overated..So much more work.You have to buy an expensive reel mower, all the $$$ you have to spend to keep it level, you have to mow more frequently.If I had a 5,000 square ft lawn I may try it but I got over 25,000 and live on a steep hillside.Mowing at 3 1/2 inches I mow every 7-9 days depending on rain.If you walk in my grass your shoe almost disappears. It still feels great when you walk on it barefooted this high. Only downsides I have found mowing this high is 1. When spring comes I have alot of clippings when I scalp it down to 1 1/2 inches.I dont do it all at one time but bring my deck down slowy for a month leading up to when it starts coming out of dormancy. 2) I had two high traffic areas over the winter.When it goes dormant it will lay down and not stand back up at this height..Right now I can walk on it but it quickly stands back up Let me know if you have any other questions
