Approximately 7 months ago we hired a guy to spray our enormous field of blackberry vines, poison sumac, and more. The results are that we have a thick field of dead vines. Our trees and ferns are doing well. We recognize that it is time to move to the next step but cannot even walk over these vines. We are considering renting equipment to reveal the soil and then perhaps plant native meadow grass seed, Could we get some expert advice so as to not make costly mistakes?

Thank you for your question. Our statewide pesticide safety faculty is unavailable. I will try to get the question to her, but will need to know exactly what pesticide was applied, in what strength, and exactly when. There are time periods that need to elapse after application, and before reentry, and some pesticides retain their toxicity longer than others. A possible method to utilize might be ‘hiring’ goats, but not if they could be poisoned. If you can get more info, we will try to assist. The other route you can take is to call the National Pesticide advice line here: http://npic.orst.edu/capro/whentoplant.html Good luck!
Thanks! Date(s) of application?
