[header] How to prune flowers [title] Deadhead flowers to remove spent growth during the flowering season. [step] As flowering plants bloom, you may need to remove spent buds to help encourage new flowers and a stronger overall plant. To deadhead a flowering plant, you want to cut the branch or stem off at a 45 degree angle, just above a new bud. 
[substeps] Depending on how thick the stems of your plant are, you will need to use either gardening shears or a hedge trimmer to deadhead your plant. Plants that grow aggressively or that produce a large number of flowers may need to be deadheaded more frequently.
