When staking perennials, which practice is recommended?

• A. wait until plants are fully grown before putting stakes in place
• B. use stakes 6 inches shorter than the height of the full-grown plant
• C. add ties as the plant stems lengthen
• D. tie plants loosely with loops of wire or twine

Answer: (A)

Stakes should be placed when you can match their height and placement to the plant’s final size, so waiting until the perennial is fully grown allows you to provide support that fits its true height and form. If you stake too early, tender stems can be damaged by the stake or by tight ties, and you may inadvertently constrain or misalign growth as the plant continues to develop. By letting the plant establish first, you can choose a stake that supports the crown without rubbing or girdling, and then use soft, loose ties to secure it. Looser, more flexible tying materials protect the stems, whereas loops of wire or tightly tied branches can injure the plant.
