Sticks are weak.  They break and splinter easily, even when just putting the in the ground.  I had to bind mine together in groups of 2-3 to get one functional stake and that stake still wasn't very sturdy.  Guess you could use these for staking light-weight vines, flowers, etc.  Some of the stakes I've broken into 3 pieces to mark the ant beds so I can find the later.  Definitely not a purchase I would make again.
