As the height of summer approaches, savvy gardeners know that one of the most rewarding tasks they can undertake is deadheading flowers and which plants to deadhead. This simple yet effective gardening technique can transform your summer garden, ensuring a continuous display of vibrant blooms well into the later months.

Unlike pinching of blooms which is removing the top or central growing point to encourage side shoots to develop and created a bushier plant, deadheading is a term for removing old or spent flowers during the plant’s growing season to increase blooms on the plant.

In this comprehensive guide, we’ll explore the art of deadheading, focusing on seven key plants that benefit most from this practice in July, and provide expert tips to help you achieve a garden bursting with color and life.

The Importance of Deadheading in Summer

Deadheading plants is more than just a tidy-up task; it’s a vital component of summer garden maintenance that can significantly impact your garden’s overall health and appearance. By removing spent blooms, you’re not only improving the aesthetic appeal of your plants but also encouraging them to redirect their energy into producing new flowers rather than setting seed.

The benefits of deadheading are threefold:

• Extended flowering period: Many plants will continue to bloom for weeks or even months longer when regularly deadheaded.
• Encourages a second flush of blooms: Some plants can be coaxed into a second round of flowering through strategic deadheading.
• Keeps the garden neat: Removing faded flowers instantly tidies up your garden beds and containers.

What to Consider When Deadheading Plants in the Summer

While deadheading is generally beneficial, it’s important to approach this task with some discernment. Not all plants require or benefit from deadheading, and in some cases, it might even be counterproductive.

Plants that typically benefit from deadheading include many annuals, perennials, and some shrubs known for their long blooming periods. However, there are exceptions to consider:

• Architectural shrubs: Plants like hydrangeas often have spent blooms that provide winter interest and should be left intact.
• Self-seeding annuals: If you want certain annuals to self-seed for next year, allow some flowers to go to seed.
• Plants with seeds for birds: Some plants, such as sunflowers and coneflowers, produce seeds that are valuable food sources for birds.

Additionally, some plants may be too challenging to deadhead effectively. Vigorous climbers or plants with very small or numerous flowers (like asters or alyssum) can be time-consuming to deadhead and may not show significant benefits from the effort.

Best Methods for Deadheading: Tools and Techniques

To get the most out of your deadheading efforts, it’s crucial to use the right tools and techniques. This not only ensures the health of your plants but also makes the task more efficient and enjoyable.

Essential Tools for Deadheading Plants and Flowers:

Secateurs (Pruning Shears): These are the workhorse of deadheading tools. A good pair of secateurs allows for precise cuts and can handle stems of various thicknesses. Look for ergonomic designs with sharp, bypass blades for clean cuts that promote quick healing.

Scissors: For more delicate blooms or when working in tight spaces, a pair of sharp scissors can be invaluable. Choose a pair with long, narrow blades for better maneuverability among dense foliage. ✂️

Fingernails: For very soft stems, such as those of petunias or pansies, your own fingernails can be the perfect tool for a quick pinch.

Deadheading Techniques:

• The Snap Method: For flowers with brittle stems, like geraniums or petunias, simply snap off the spent bloom at the base of its stem with your fingers.
• The Cut Method: For woodier stems or larger blooms, use your secateurs or scissors to make a clean cut. Always cut just above a leaf node or bud to encourage new growth.
• The Shearing Method: For plants with numerous small flowers, like alyssum or candytuft, you can use scissors to shear off the top few inches of growth once flowering has finished.

Tips for Effective Deadheading:

• Always ensure your tools are clean and sharp to prevent disease transmission and make clean cuts.
• Make your cuts at a 45-degree angle to allow water to run off and prevent stem rot.
• When using secateurs, position the blade so that the stem is cut against the hook, not the anvil, for a cleaner cut.
• For plants with multiple flower heads on one stem, wait until all blooms on that stem have faded before cutting back to the base of the stem.

Investing in quality tools like secateurs and scissors not only makes deadheading easier but also improves the overall health of your plants. Remember, sharp, clean cuts heal faster and are less likely to introduce disease.

By mastering these techniques and using the right tools, you’ll be well on your way to maintaining a vibrant, continuously blooming garden throughout the season. Now, let’s explore the seven key plants that benefit most from deadheading…

7 Plants to Deadhead in The Summer

Delphiniums

Delphiniums are known for their striking tall spikes of flowers in shades of blue, purple, pink, and white. To encourage a second flush of blooms:

• Cut back the entire flower spike to the base once the majority of flowers have faded.
• Make your cut just above a set of leaves to promote new growth.
• Ensure the plant is well-watered and fertilized to support new flower production.

Roses

Roses are perhaps the most iconic plants associated with deadheading. For repeat-flowering varieties:

• Remove individual spent blooms by cutting back to the first set of leaves below the flower.
• For cluster-flowering roses, wait until the entire cluster has finished, then cut back to the first set of leaves below the cluster.
• Use clean, sharp pruners to make clean cuts and prevent disease transmission.

Dahlias

Dahlias can bloom continuously from midsummer to the first frost with proper care:

• Remove spent blooms by cutting the stem back to a main branch or to the next set of leaves.
• Learn to differentiate between spent blooms and buds: buds are round and firm, while spent blooms are pointed and soft.
• Regular deadheading encourages the plant to produce more flowers rather than set seed.

Lupines

While lupines have a relatively short blooming period, deadheading can sometimes encourage a second flush:

• Wait until the flowers at the base of the spike start to turn brown before deadheading.
• Cut the entire spike down to a set of healthy leaves.
• Keep the plant well-watered to support potential new growth and blooms.

Cosmos

These cheerful annuals can bloom continuously with proper care:

• Pinch off individual spent blooms with your fingers or use pruning shears for larger stems.
• Cut back to just above a leaf node to encourage branching and new flower production.
• Regular deadheading keeps cosmos looking tidy and encourages prolific blooming until frost.

Salvia

Salvias are not only beautiful but also excellent for pollinators. To keep them blooming:

• Begin deadheading when about a third of the flowers on a spike have faded.
• Cut the stem back to just above a set of leaves or a side shoot.
• This practice encourages bushier growth and continued flower production.

Peonies

Although deadheading peonies won’t produce more blooms this year, it’s crucial for next year’s display:

• Remove spent blooms by cutting back to the nearest set of healthy leaves.
• This practice helps the plant focus energy on root and bud development for next year’s growth.
• Deadheading also improves air circulation, reducing the risk of fungal diseases.

Additional Deadheading Tips

Geraniums

These popular container plants benefit greatly from regular deadheading. Simply snap off the faded flower heads where they meet the main stem to encourage continuous blooming.

Fuchsias

While fuchsias naturally drop their spent blooms, removing the small berry that forms after the flower falls can encourage more prolific flowering. Pinch these off carefully to avoid damaging developing buds.

Conclusion

Incorporating deadheading into your July gardening routine can have a transformative effect on your summer garden. By focusing your efforts on these seven key plants and following our expert tips, you’ll be rewarded with a prolonged season of vibrant blooms and healthier, more vigorous plants.

Remember, while deadheading flowers is generally beneficial, it’s also important to strike a balance. If you’re interested in collecting seeds or providing food for wildlife, consider leaving a few spent blooms on each plant. This way, you can enjoy the best of both worlds – a beautiful, floriferous garden this year and seeds for future plantings or winter bird food.

As you embark on your deadheading journey this July, take time to observe your plants closely. This practice not only helps you identify which blooms need removing but also allows you to spot any potential issues early on, ensuring your garden remains healthy and beautiful throughout the summer months and beyond.

By mastering the art of deadheading, you’re not just maintaining your garden – you’re actively shaping its ongoing beauty and vitality. So grab your pruners, head out into your summer garden, and let the satisfying snip of deadheading be the soundtrack to your gardening success this July.​​​​​​​​​​​​​​​​
