Do you love having overflowing blooms that turn heads and make your neighbors green with envy? The secret might lie in a simple tweak that many garden enthusiasts overlook: deadheading.
While it may seem counterintuitive to snip off those seemingly harmless blooms, this practice actually maintains the visual appeal of your garden and stimulates further flowering.
By mastering this technique, you can transform your garden into a breathtaking oasis of color and fragrance.
What Is Deadheading Flowers?
Deadheading is a simple yet essential gardening practice that can improve the health, appearance, and longevity of your flowering plants. It is the process of removing spent or faded blooms from plants. It’s a small investment of time and effort that yields impressive rewards.
How Do You Deadhead Flowers Like a Pro Gardener?
Deadheading isn’t a one-size-fits-all process. The technique you use depends on the type of plant you’re working with.
Deadheading Flowers with Thin, Soft Blooms
For delicate flowers like petunias, pansies, or zinnias, you can simply pinch or snip off the spent bloom at its base using your fingers or a pair of pruning shears or scissors.
If the flower has multiple stems, follow each stem down to the main stem or set of leaves and make your cut just above that point.
Deadhead Flowers with Tough, Woody Stems
Some plants, like roses, have thick stems that require a different approach. For these, use sharp pruning shears or secateurs to cut the stem at a 45-degree angle about ¼ inch above a leaf node or bud eye. This type of cut encourages new growth and helps prevent disease.
Be gentle and avoid damaging the surrounding foliage or stems. And always remember to clean your tools after each use to prevent the spread of disease.
Why Is Deadheading Flowers Important?
Deadheading flowers is important for several reasons:
- Promotes Continuous Blooming: Deadheading tricks the plant into thinking it hasn’t yet reproduced successfully. This prompts it to produce more flowers in an effort to set seed.
- Redirects Energy: By removing spent blooms, you redirect the plant’s energy from seed production to new growth, resulting in healthier foliage and more vibrant flowers.
- Maintains Appearance: Deadheaded plants look tidier and more attractive than those with fading blooms.
- Prevents Self-Sowing: Deadheading helps control unwanted seedlings from popping up all over your garden.
Which Flowers Will Have More Blooms if You Deadhead Them?
Ward Upham, a horticulture expert from Kansas State University, recommends deadheading the following plants for increased blooms: (ref)
- Annuals & Perennials: Hard geraniums, coreopsis, petunias, marigolds, snapdragons, begonias, roses, campanulas, blanket flowers, delphiniums, zinnias, sweet peas, salvia, scabiosa, annual heliotrope, geraniums (Pelargonium), and yarrow.
However, Upham notes that some plants do not require deadheading, including:
- Vines & Some Bedding Plants: Sedum (Autumn Joy), Melampodium, Impatiens, most flowering vines, Lythrum, periwinkle (Catharanthus), and wishbone flower (Torenia).
What Are the Deadheading Methods?
The best method for deadheading will depend on the type of plant you’re working with.
Pruning
This involves using bypass pruning shears or secateurs to cut off the spent flower stem. This method is best for plants with thicker, woodier stems, such as roses or hydrangeas.
Make a clean cut just above a set of leaves or a new bud. This encourages the plant to branch out and produce more flowers.
Pinching
This method is ideal for plants with softer stems, such as petunias or pansies. Simply use your thumb and forefinger to pinch off the faded flower at its base, just above a set of leaves.
Pinching is a quick and easy way to deadhead, but it may not be suitable for all plants.
Shearing
This involves using garden shears to cut back a large number of spent flowers at once. This method is often used for plants that produce many small flowers, such as lavender or alyssum. Shearing can save time and effort, but it’s important to be careful not to cut back too much, as this can damage the plant.
If you’re unsure which method to use, consult a gardening guide or expert for advice.
When Is the Perfect Time to Deadhead Your Flowers?
The perfect time to deadhead your flowers is as soon as you notice the blooms fading or wilting. This usually happens when the petals start to lose their color or texture, or when the flower head begins to droop. Don’t wait for the entire flower to die completely, as this can encourage the plant to focus on seed production instead of new growth.
Deadheading should be done regularly throughout the growing season to encourage continuous blooming. Make it a habit to check your plants every few days and remove any spent flowers you see.
There are a few exceptions to this general rule. Some plants, like coneflowers and black-eyed Susans, produce attractive seed heads that can be left on the plant for winter interest or to feed birds.
