How to stake an apple tree
Purchase a 3 foot (0.91 m) 2x2 inch (5.08x5.08 cm) piece of lumber.
You can purchase the wood for your stake at a hardware or home and gardening store. Once you get your stake, use a knife or a hand sander to taper the end of one side of the lumber.
Alternately, purchase a piece of wood that is already tapered at one end. You can also use a bamboo cane as your stake for saplings.
