I try not to use pesticide unless absolutely necessary, fertilizer is a must though, be it miracle grow or put into the ground pre-planting. Herbicide to clear the land then keep it covered with tarps after is the plan so I don't have to spray anymore. Hoping to kill all the rhizomes, they are a pain. Also using weed barrier as well, so that should take out a good portion, I'll leave that down until I have to plow and till again.
