Weed control is the most difficult problem when establishing wildflowers. Weed seeds are present in many situations and lie dormant, but viable for long periods of time. Most areas converted to wildflowers will have a fair amount of weed seeds in the soil ready to germinate when conditions are favorable.
During the first year, we recommend 2-3 clippings at a height of no less than 6-8 inches. Minimizing the amount of litter left is important so seedlings can have full sunlight and a chance to compete with annual weeds. Clipping the annual weeds a few times will also keep them from producing seed heads and going to seed in the future.
