Deadheading Basics: Which Flowers Benefit Most (And Which Don’t Need It)

I was 14 years old when I first learned the concept of deadheading from my mom. Initially, what worried me was the word “dead” in the name, which made me think she was killing her plants in some way. 

However, as time went by and I grew older, deadheading has now become a late spring ritual for me. Today, we’ll go over some deadheading basics and discuss which flowers can benefit from it the most! 

Let’s dive right into it!

What Is Deadheading & Why Do It? 

In the simplest terms, deadheading involves removing old flowers to encourage new ones.

You want to make deadheading a consistent practice in your garden because it promotes more flower development, longer bloom time, and just makes the landscape appear neater. 

Quick tip: You don’t need many tools for deadheading. Just use sharp scissors or pinch off the flowers using your fingers; it’s that simple.

7 Flowers That Benefit Most From Deadheading

1: Petunias

Deadheading petunias promotes fuller growth and constant blooming, both the things which will make your garden appear more beautiful than ever. If you find your petunia growth to be leggy, deadhead regularly to reverse it.

2: Zinnias

Like petunias, zinnias also grow thicker and fuller through deadheading, leading to better blooming results and keeping garden color going into fall.

Here’s a simple guide on how to deadhead zinnias to keep them blooming their best.

3: Geraniums (Pelargoniums)

Removing old geranium flowers after their blooming period keeps them tidy and blooming at their best. It also helps prevent seed formation. This includes both zonal and ivy geraniums.

4: Marigolds

In marigolds, deadheading encourages nonstop bloom development. It’s also a good way to prevent common issues with marigolds like mildew and seed drop.

This guide explains exactly how and why to deadhead marigolds to keep them healthy and vibrant.

5: Cosmos

Deadheading cosmos flowers after their blooming period ends encourages fresh flushes of flowers through summer. Due to their delicate nature, the blooms are also super easy to deadhead, even with your fingers. 

6: Coneflowers (Echinacea)

Deadheading coneflowers early boosts both bloom quality and quantity. You can, however, also choose to leave late-season blooms for birds if you want.

7: Blanket Flower (Gaillardia)

Removing spent blooms keeps blanket flowers flowering longer and healthier without unwanted issues. You actually want to deadhead these often for the best garden display.

1: Impatiens

Impatiens are known for their self-cleaning capabilities. Their old blooms fall off naturally, meaning you don’t have to manually remove them one by one.

2: Begonias (Most Types)

Most begonia varieties, especially tuberous and wax begonias, don’t really need deadheading. They maintain well on their own, so no extra care is needed.

3: Vinca (Periwinkle)

Periwinkles bloom continuously on their own without needing to be deadheaded. As a matter of fact, deadheading can potentially be harmful for these perennials.

Note: Even though they’re low-maintenance, it’s important to note that vinca is actually considered invasive in many regions. It can spread quickly beyond where it’s planted and outcompete native species.

4: Lobelia

Lobelias usually self-clean, which is why it may be better to only trim them very lightly if they get leggy.

5: Sweet Alyssum

Despite the delicate sounding name and appearance, sweet alyssums are super low-maintenance and respond much better to some light shearing rather than full-on deadheading.

Best Deadheading Tips You Must Remember
