Pull all the weeds that are up, then spreed a product called Preen this will keep weed seeds from germinating but doesn't harm the plants that are already up and growing
What weed killer can I use that won't kill my flowers? They are beginning flowers that have not budded yet, they are cock's combs. Please help. There are so many weeds mixed in with them and I'm afraid to pull them because I am pulling the roots of the flowers up too.
Use layers of newspapers to cover up the weeds (you can place some dirt on top to help hold them down, etc). This will prevent the weeds from getting light and it's easy and inexpensive. :)
