I have a very large area near the front of my yard that is covered with poison ivy. In other words, I can't get rid of the ivy easily or without desperate measures.
My question is this: Will spraying Poison Ivy weed killer work better if I do it right before a hard frost? My thought is that what little nutrients reach the plant after the frost will all be poisoned and therefore will kill the plant better than simply spraying and praying. Or...I could be totally wrong and it will just negate the effect of the poison completely.
Any thoughts or advice? Thanks!
