This is a wildflower meadow that Ning installed this spring. He covered the original grass with black plastic to kill off grass and weeds. That took a few months. Then he spread Pacific NW wildflower seed mix (outsidepride.com) and that's about it. I did add some non-wild poppy seeds to the mix, to see what happened. Now in mid-June, this is about 3 or 4 months after he spread the seeds. The honeybees, and bumble bees, are buzzing around happily.
