Pruning: Pruning Mexican sunflowers isn’t necessary but can help to get lanky plants under control or to keep overgrown plants in bounds. Keep in mind that you may sacrifice some blooms when pruning. Cut off the top 1/3 of the plant when it’s experiencing a lull in blooming to both deadhead and tidy the plant.
