To remove a decoration, drag the decoration back down to the gift tray. 

And, you can also move your candy plants around the garden by dragging them to a new spot! 

Sometimes, pesky weeds will grow in your garden! Simply drag them to uproot them. You may also see a mole digging things up! Tap the critter to make it run away.
