We were gone for quite some time due to a family medical situation. Today I am pulling up thistles that have buds on them. We live in a small city surrounded by farm fields. I would like to get rid of the thistles for good if not this year then next year. I am wondering if any of you have this problem and what you use to eliminate the thistles? I never use to have them in my garden but once they got in it has been a battle.
