One thing we have to remember is that weeds make up a large part of a deers diet and fertilized weeds do have a higher food value than they would otherwise. Nobody wants their foodplot to be overcome with weeds but it's not always as bad as it may seem. Especially with PowerPlant or the Pennington equivalent. That assumes that you do get enough of the vine beans and peas to climb the weeds of course. Both those vine plants in PP need something to climb or they won't produce nearly as much and also one of the pluses of PP is that it is so tall that it provides it's own cover. That makes deer feel secure and when they feel secure, they'll use your plot more. If only frost didn't kill it so that it could be growing when gun season started.
Yes, it is frustrating when you get a lot of weeds in it. I have one PP plot that has gotten overrun with pig weed after 5 years of PP and I am going to go with RR corn next year just to try to get rid of the pig weed seeds. But I definitely intend to use PP again in the future.
