How often do you water and for how long? How high/low do you mow? The weeds can be handled by something like Spectracide with Atrazine. But I would wait until the grass returns. I have gotten excellent results for fungal disease using ordinary corn meal. It is an organic approach that the experts at Texas A&M swear up and down does not work, but it has worked for me every year since 2002. It is a complete cure in 3 weeks. I am suggesting you try that because corn meal doubles as an organic fertilizer. Your spots don't look that much like a disease, but it could be. If you did not have the really healthy stand of grass right by the sidewalk, it would look more like disease. I would hit it with corn meal at 20 pounds per 1,000 square feet now and again in 3 weeks. If you don't see new grass coming up in 4 weeks, then get a commercial fungicide that works in your heat/precipitation zone - read the label closely to see how to apply and when. Corn meal has no restrictions on how or when. Then once you get the grass growing, zap the dollar weed (I assume dichondra or some other easy weed) and let it grow. And if you have not already raised your mower to the highest setting, do that yesterday.

can you rule out lichens .. if it is that.. its irrelevant .... a gift from the garden gods .... need that pic ... will await such ken Here is a link that might be useful: link

This is a guess, only a guess as there are many maladies that affect "flowering trees." If your flowering tree is a hawthorn, what you might be seeing is the result of cedar-quince rust. hortster Here is a link that might be useful:

I have vast areas of garden covered with Vinca (periwinkle)which have been very healthy for years. In the last year, a bug or fungus, small raised brown spots on the underside of the leaves, has been spreading quickly. The leaves curl and the plant does not grow like the healthy ones - it doesn't spread and cover ground it grows straight up and after a couple of months - it turns brown and dies. I have been unable to identify what this is and how to deal with it. Can anyone help? Thanks
