My chrysanthemums get tall and lanky and flop over onto the ground in fall. What can be done to prevent this?
Pinch newly planted and established mums from spring to mid-summer. Remove the upper 1 to 2 inches of the shoots when the stems are 6 to 8 inches tall. New lateral (side) shoots will develop along the stems. Pinch again when the side 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 mums results in bushy, compact plants with additional flowers.
