Should I burn my wildflower garden and start over?

Don’t burn it. Because you might then have trouble getting things to grow. I would try a rock rack to start. It take work. I’ve been there.

Try weed-eating the whole area at about 4" from ground & then rake GENTLY or weed blower area - what is LIVE will grow some more, & you will have gotten rid of most of the dead stuff. Call your local Ag Extension service for sources of seed of wildflowers just for your area - not mixes but single types you like & overseed what you put down last year.

My vote is to burn it off, if allowed. Here in drought ridden CA it's against the law. Farmers and ranchers do spring burning and burn different pastures each year. Sort of like crop rotation. That way you have a start fresh. You will need to amend the soil before planting anything. I tried wildflowers too. Mine were a joke. My girlfriend bought the same packet, hers were beautiful.

This year just go ahead and cut the brown stalks. Don't pull them out. Next year mow it after it has turned brown or after the first frost.

I love our wildflower garden.

old quote from my Grandma..."a weed is just one of God's plants you don't want.."

I don’t think newish gardeners realize what they are getting into when they decide they want a flower garden. The wildflower seed mixes are enticing, but what they don’t tell you is that some of the seeds are invasive species. I’ve been gardening for a long time and in my experience it’s really hard to grow a wildflower garden without having a weed pit. Don’t burn it though! I would recommend cutting everything down and covering the area with cardboard. Give it a few weeks before trying to do something with it.
