Zone 9, citronella geranium. My plants are not bushing, but growing straight up. Potted them in the fall. I brought them inside for the winter. I feed every two weeks, now they are back outside. Do I punch them back? If so how much?
Yes, prune back long, leggy mosquito plant stems any time of the year. Cut or pinch the stems back, leaving at least three sets of leaves.
As the plant grows, pinch back stems to keep them at about 4 to 6 inches in length. This will keep your plant bushy and healthy.
