Trim cleome plants back by half at the time of planting if they appear lanky or foliage is scarce.
Snip off dead leaves and those that have been damaged by insects or disease anytime throughout the season.
Shear cleome plants back during middle summer if growth becomes lanky or flowering slows. Avoid cutting past the lowest leaf bud because you will be left with stems and no new growth.
Pinch the ends of newly formed foliage to encourage bushier growth.
Remove each flower as it fades to improve appearance and encourage repeat blooms.
