Cheapest method to gain rid of dandolines?
Answers: The cheapest way is to appropriate a long screwdriver, and dig them out by paw, making sure you get the stroke root. Insert into the ground along the dandelion root to pop the dandelion and at least 2-3" of its root out of the ground. Plants will regenerate from root pieces, in particular from the top half of the root, so try to verbs as much of the root out of the ground as possible.
Roundup or other formulations of glyphosate are not the best choice for dandelion control. The chemical quickly knock back the leaves, but doesn't annihilate the root. The plant that regenerates habitually has a group of stunted stems coming back from the root, that break bad easily, making it even more difficult to verbs out.
The cheapest way as you would expect is to remove by hand. Try to get hold of as much of the root as possible. I saw a gardening expert on TV and he advised that if you can't grasp them all dug up, to at most minuscule make sure you snap bad the flower head up to that time it goes to pip. That way you are warfare only them but if they budge to seed you will own hundreds of tiny little seeds trying to put down roots.
