Second one looks like Gnaphalium purpureum -- Purple Cudweed. http://www.discoverlife.org/ed/si/GA/acc/burney_harris_lyons_ms/herbs.html#Gnaphalium HTH Chris Here is a link that might be useful:

Thanks very much for all your replies! The mint 'bush' was huge, so I can see it taking over a garden. Looks like this poor garden has been neglected for years and things just got out of control. I'll plant the mint in a pot as suggested, find a shady corner for the lily of the valley plants and skip the goldenrod and sweetpea. Thanks again... I may be posting more pictures in the future because I can't tell a plant from a weed :) Kristine

Lushgarden77, I am going to assume the turf is tall fescue. This does look like it could be brown patch, hard to tell from this picture. Conditions that are favorable for brown patch are daytime temps 80+ and nighttime temps 60+. According to weather.com your daytime temps are there but your nighttime temps are mostly in the 50's. That being said your particular micro climate might be a little bit warmer, and along with your watering schedule you could definitely produced the conditions to favor brown patch. First thing to do is stop watering twice a day. When you need to water set your irrigation system up to run early in the morning just before sunup. How much to water? The general rule is an inch of irrigation or rain a week. You said this is a sandy soil so you will be better of running your irrigation twice a week to put out a half inch of water each time. Second, because of the stress your turf is under right now, you should only mow once a week. Third, when you do mow make sure to mow early in the morning, finish mowing before 11:00 a.m. Tall fescue can take alot of abuse from disease and drought but it cannot take any traffic when in this condition. Should you use a fungicide? It looks like the damage is done already, and I would think that your disease pressure should be going down in the next few of weeks, save your money for seed in the fall. However, if you need a product for next year use Heritage G in early December at the high rate it will get you a thirty plus days of control of brown patch. The good news is I don't think you will need the fungicide next year, your disease pressure is very low there, if you change your watering practices. Also no nitrogen fertilizer in the summer. Fertilize with nitrogen one pound per thousand square feet of nitrogen early fall and mid spring. Also, a large percentage of tall fescue affected by brown patch will come back by the following spring. So just wait till until late summer/early fall to reseed the damaged area's with tall fescue.

Since it was there after the storm, it makes me think it might be hail damage. Deanna
