This is my second year growing outdoor. Last year my crop was pollinated, the herb still came out decent. But, no one likes seeded weed. I hope that a repeat of last year doesn't happen this year. I have tried talking to my neighbors who grow, they are mostly Hispanic and speak poor English. So it is hard to try and educate them. Is their any preventive method for blocking pollen, or am I SOL? Thanks for the input!
