I have a lot of trees in my yard, how can I get rid of the sapling that start off my trees?

Question

They are starting to take over my yard, even though I mow them down every other week.

Answer 1

Cut down some of the big trees and pull the saplings out of the ground.

Answer 2

dig up the roots

Answer 3

mowing them down you are leaving the roots, just pull them up that way you get the roots too, they are small so it won't be hard.

Answer 4

place a board over them so they can't get any sun light to grow

Answer 5

If you're talking about "suckers" - basically, branches growing straight up from the base of the tree, or from the horizontal roots nearby...you mow them, or cut them with pruners.

There is a product called "Sucker Stopper", that you can spray on the cut surface after you snip them off.  HOWEVER - it's not good to use that product on a stressed tree.  And by definition - a tree that produced lots of suckers is less than healthy.  

If you're talking about seeds that sprout, after a few mowings, you should have cut them all, and they'd be done.
