Clarifying two common gardening tasks and when to use each

Introduction

Even experienced gardeners sometimes confuse deadheading and cutting back. Both involve trimming plants, but each has a different purpose and impact. Knowing when and how to do each will help you keep your garden looking its best throughout the growing season.

What Is Deadheading?

Deadheading is the process of removing faded or spent flowers. This encourages the plant to redirect energy from seed production into new blooms and healthy growth.

Why it matters:

  • Promotes continuous flowering in annuals and perennials such as Supertunia®, Superbena®, and Superbells®.

  • Keeps plants neat and attractive.

  • Reduces the risk of disease and pests caused by decaying petals.

How to do it:
Use clean pruners or pinch off old blooms just above the first set of healthy leaves or buds. Check plants weekly during the growing season for best results.

What Does Cutting Back Mean?

Cutting back involves trimming back stems or foliage to rejuvenate a plant, promote fuller growth, and improve overall appearance.

Why it matters:

  • Revives plants that have become leggy or tired midseason.

  • Encourages bushier, more compact growth.

  • Helps perennials store energy for the next growing cycle.

When to cut back:

  • Midseason (July–August): Many annuals benefit from a light trim to encourage new blooms.

  • End of season: Cut back perennials after frost or when foliage dies back to prepare for winter.

Quick Takeaway

Deadhead to keep flowers blooming.
Cut back to refresh and shape plants for stronger growth.
Both are essential for maintaining healthy, vibrant gardens from spring through fall.
