TW (my friend) does it apply to AMAZE? I guess it could if applied one application real early, and another near Summer. I really like AMAZE because it is one of the longest acting pre-emergence on the market, followed by Demension. Typically with Amaze you can use it twice a year, once in Spring and again in Fall for year round protection. If you live in an area that gets a lot of rainfall, you can go 3 times a year. Just be careful using Amaze around trees and shrubs, or use Demension.

Thank you, that's what I thought but just wanted to confirm it.

I didn't notice it was CGM. I agree with TW on that. I used 20 pounds per 1,000 square feet 8 times last season and never noticed a difference in weeds. I mean, how much do you have to use to get the effect? I was doing it to fertilize anyway. It is the best organic fertilizer I know of.

For the 1 tbsp, as much as is convenient to get it down. I'm presuming Prodiamine granular? I use about ten gallons because I use a hose-end. One gallon would be more convenient in a backpack sprayer. I might lightly irrigate that in--ten, 15 minutes just to wash it off the leaves--but it's not necessary if you don't want to. If you're going to overseed in August, go very light on the Prodiamine if you use it at all! It'll suppress out grass seed just like crabgrass, and CG likes sprouting in August as well. Good CG suppression through summer is going to mean very poor grass sprout in August. Page 2 of the manual shows the bar chart for pounds per acre (roughly tbsp per thousand) for months of protection. 2 months (May to August) is off the bottom but...well, if we finagle a bit and estimate (which we really shouldn't do because we have no assurance that this remains linear off the listed scale), we'd come up with an estimate of about 0.33 lb/A or 0.33 tbsp/thousand application rate to achieve 2 months of protection. (The linear equation is actually 5.2T + 0.2 for those who are curious, with T being tablespoons used by my estimate, but I'm just eyeballing it so you may come up with different answers). Even so, some suppression of sprout is to be expected. Post that, the grass should be on its third or fourth mow before applying Prodiamine again; it can kill young grasses. By late September, it's marginal, but you should be OK...still, it may slip into October.
