Take advantage of summer's heat to grow warm-season vegetables like peppers. Some pepper varieties grow very tall and lanky and will fall over if they're not supported. Staking the plant is an ideal method to keep this from happening. Pound the stakes into the ground when the pepper plant is a seedling. Inserting the stake next to a mature pepper plant can damage its underground root network.
Measure a spot approximately 12 inches from the pepper plant seedling. This is the spot where you'll insert the stake.
Pound the wood stake into the soil using a hammer or mallet. For the sturdiest support, pound the stake approximately 6 inches into the ground.
Wait for the pepper plant to grow to a minimum height of approximately 1 1/2 feet. At this point, the plant will start to get lanky and will need support.
Tie garden twine around the pepper plant's main stem approximately 15 inches off the ground, according to the University of Arkansas. Tie the other end of the twine to the stake. Provide a couple inches of slack to give the plant room to move in the wind.
