If memory serves me (and it doesn't always!!), I think the cost for enough product to treat 5 acres is somewhere around $200, give or take. It could be the best investment I've ever made or it could be a lesson hard learned.
My grandpa used to tell me bought experience is the best kind (because you won't forget it).
I think my reluctance is centered on the "high hopes" the product offers. In the past, I've always found the "if it sounds too good to be true" theory to pretty reliable. But, then again, if I'd always followed that rule I wouldn't have the wonderful wife I've had for lo' these many years!
So, no guts - no glory, no fools - no fun, I think I'll order a small amount and give it a try. The fact sheet says I should see a difference in 5 -6 weeks.
I'll post my observations and the results at a later date.
Thanks for your replies!!
