Powdery mildew or stripe smut. Need more information to determine which one. How do the affected grass blades look? What are growing conditions? Are these happening in shady areas? What are weather conditions? Control depends on more info also. Last time you fertilized?

I'm with you on not sharing. I nearly lost ALL my herbs due to these and other caterpillars. One set were really beautiful - green with black and red spots/stripes. But I wanted my plants more. I used the BT powder I got from an organic dealer and it worked well. Alas, it was something different that infected my tomatoes, and none survived. My neighbor has a plum tree that was getting attacked by birds. She decided to 'share' so was eating them sour just so she could get them before the birds. Then I told her it was the grackles eating them....and she had our ripe peaches (we put a net over the peach tree) and decided this race to get them before the grackles was maybe not such a good idea....

If you can come up with an old piece of chain link fence and a couple logs you can make a drag to pull behind the mower. Basically the chain link will scrape a little dirt off of the high spots and drop it in the low spots. It may take a little while but as long as it's not too bad this will work wonders for smoothing out the bumps. If it were me, I would hold off doing anything that will leave you with bare dirt for now. Otherwise you will end up with more weeds to deal with and there's a good chance you could have some soil erosion from storms or heavy rains during the summer. Leaving the weeds alone will allow them to hold the soil in place. From there, get started with the "destruction" process in mid to late July. About 1 week prior spray everything with RoundUp to kill off all of the weeds. Once the destruction is complete and the lawn area has been smoothed and ready for seed begin watering lightly 3 times per day for a couple of weeks to germinate any weed seeds that were left behind. By lightly I mean just enough to keep the very top layer of soil damp. Spray anything green again with RoundUp. By this time all this is done you will be into your ideal time for seeding which should be mid to late August for you. In the meantime, use the search feature here to learn proper seeding, watering, fertilizing, and all the other stuff involved in maintaining the new lawn as all this is important if you want the lawn to be successful. It's really not too hard but you don't want to spend all this money to have it go wrong. You've got a good group of folks here on the forums to help you through it and answer any questions that come up along the way.

Gorgeous pics, PK! Lauren, I'm just southeast of you In Waxahachie. I have full southwestern sun in front & part shade in back & on one side. The other side is "ungardenable". Just a narrow strip between the house & the neighbor's wood fence, it's just a walkway for me & a nursery for poison ivy & trumpet vine! I started along the sidewalk & expanded from there; seems like it keeps me from straying too far, messing up proportions, & having to undo & re-do. I put a rosemary on each side of the sidewalk close to the front door; it's evergreen & it smells like Christmas when I get the mail! There are nandinas at the corner of the house, softening the sharp corner, & right now they're at their best, still green & loaded with red berries. Along the side next to the neighbor I put 3 Lady Banks roses, as a hedge of flowering shrubs. They do get sparse in the winter but they never have gone totally bald. There's a Martha Gonzales rose on each side of the sidewalk where it intersects with the public sidewalk that defines the "hellstrip". They're compact, pretty much evergreen, & they have gorgeous blue-green foliage & burgundy stems, & the flowers are a bright cheery red. I widened the beds on the front & side of the house, & they have salvias, mums, flame acanthus, lemon mint (I love it for the "makes you smile" fragrance, but it does spread!), old irises, mistflower, a couple of crinums for proportion, & a lot of "tote & plop" plants, the ones you can't resist bringing home, & then you have to tote them around until you spy a bit of earth where you can plop them! Along the sidewalk leading to the Marthas, there are dusty miller, obedient plant, datura for proportion/contrast, & a few dwarf cannas that I may move this spring...it seems like they're more backyard flowers than front yard. Along the hellstrip on the northeast, I have roses, crinums, tons of irises, & some tall Mexican petunias that have to be watched lest they take over the universe but which bloom in the summer when everything else suffers in the heat. In the shadier areas, there are cast iron plant, Jewel of Opar, pigeonberry, & probably some other stuff that I can't remember right now! Although my little plastic wading pools are no comparison to PK's (I pile up mulch around them & pretend I can't see the blue plastic), I have 2 of them in the back, one for bog plants & one for water garden plants. At the corner, on the small wedge-shaped area defined by 2 streets & the intersection of the 2 sidewalks, there are red yucca, salvia, a four o'clock, & a big group of irises, Scattered throughout the whole place are paperwhites, narcissus, lycoris radiate, etc. Between all of this, I'm working diligently to replace the huge brittle old hackberries with juniper, olive, gingko, crepe myrtle, & loquat, & to lay down brick pathways. The things I've learned about cottage gardens & other lawn-less gardens are: If you possibly can, draw your lot on paper, sketching in the house, fences, sidewalks, utility areas (I keep the compost pile & the trash can in the narrow strip by the neighbor!). Draw in pathways where you generally walk, & keep those areas clear. You will get tired of walking around a planting area to take out the trash! I just happen to know this. Make a list of some things you like, & color code the list for the environments those things need, such as shade or sun, & their mature size (do as I say, not as I did: I'm the person who once planted a Mermaid rose beneath the eaves!). This will also keep you from planting bur oaks beneath electric lines. I haven't done that one, but it broke my heart to see the electric company's "trimmers" mutilating 100-year-old oak trees in my neighborhood, cutting big "V"s in the middle... Pencil in some things, such as rosemary by the front door, lemon mint by the back gate, bird feeders where you can see them from the window you use most-such as over the kitchen sink or in front of the computer desk. Pick long-lived plants, or plants that self-seed, when you can. Plant irises where they can be mulchless, & where the neighbor's magnificent century-old oak tree won't shower them with bushels of leaves every autumn. Plant the things that need more attention close to where you will see them every day. Make room for a sitting/tea-drinking/visiting area, including a table & enough space to scoot your chair back without bumping a flowerbed or smacking the edging. Enjoy your garden, engage with it, play with it, have fun!
