Weather for Thursday, 10/12:
High 82, Low 65

Weather for Friday, 10/13:
High 90, Low 69

Weather for Saturday, 10/14:
High 82, Low 56

Weather for Sunday, 10/15:
High 74, Low 52


Question: Precipitation expected only today and none of the dates listed above. Can I lay down some pre-emergent in the afternoon between any of these dates?

Also, is the Clegg's cocktail still useful as a winter pre-emergent or is it strictly to be used in the Spring?

Apply it now when it’s convenient for you - don’t overthink it - just be sure it’s watered in via rain or sprinklers.

Cleggs winter weed cocktail (Fertilome Weed Free Zone + Atrazine + Surfactant) is a post-emergent mixture, though Atrazine has some pre-emergent activity, and yes you can use it now when daytime temps are in the 70s, of course don’t use it on actively growing Bermudagrass.

Thanks Craw. I can get a 5 lb bottle of Prodiamine for $99 by tomorrow.

I can get through my front and back yards with a 2 gallon sprayer. How much would I need to use? And does it have a fairly sustainable shelf life after opening? I wouldn't want to buy a bottle of this stuff and have it go bad. Also, is it applicable to more than just winter pre-emergent?

Sorry for all the questions. Trying to tackle my yard better so that it looks better in the next year or so.

Double check the label, but I think it’s 0.5 oz or 3 tsp per 1,000 sq feet.

5lbs will last you years, give some away to your neighbors or a friend.

It should be fine for 5-7 years if kept out of extreme temperatures.

Yes, use for both fall and spring applications.

Thanks for the correction Hedge. See folks, that’s why you read the label.

I wrote 0.5 oz on my container so I just assumed that converted similarly to 3 liquid teaspoons.
