How often should I pinch my mums?

Question:

How often should I pinch my mums?

Answer:

Pinch chrysanthemums 2 to 3 times from spring to mid-summer.  Remove the stem tips when the shoots are 6 to 8 inches tall.  New lateral shoots will develop along the stems.  Pinch again when these new shoots reach a length of 6 to 8 inches.  Pinching can be done with your fingers or a pair of hedge clippers.  Continue pinching until early July.  Pinching results in bushy, compact plants with additional flowers.
