Weeding Pre-weeding. Neighborhood Forester is flagging the native grasses we want to keep before other volunteers will help weed out the invasive non-native grasses we want to remove. Photo: Brad Lancaster Post-weeding. Desired native grasses left in place. Invasive non-native grasses removed. Native wildflower and restoration seed mix can now be sown.Though for a truly successful weeding, a steward living on the block will need to periodically check for, and pull, weed seedlings as they emerge. This gets easier over time as the amount of weed seed is continually reduced while native plant seed continually increases.
