Thistle seeds bad?
I bought a thistle sock and attracted some goldfinches this spring. I have been really excited about having them in the yard. Today I was going to buy more seed and my husband said, "You can't put that in the yard! The thistles will sprout and be all over the place!"
He says they have super long roots and we'll never get rid of them.....I'm thinking if that's true we already have them as the sock has been out there a week or so.
What do you all say about the thistle seed, please? Is there anything else to attract the finches besides waiting for the coneflowers and is it the purple ones they like?
