Zinnias make gorgeous additions to any landscaping. These large flowers come in many vibrant colors that can accentuate both home and garden.
Zinnias are the perfect cut-and-come-again flowers so that you can pick beautiful bouquets all summer long. In fact, the more flowers you cut, the healthier your plants become.
This article will teach you how to deadhead zinnia to extend bloom time and get the most out of these lovely annuals.
What Does it Mean to Deadhead Zinnia?
Zinnias are annual flowers, meaning they only last for one reproductive cycle before dying and going to seed. Deadheading zinnia is a way to trick the plant into growing and blooming for longer.
Healthy plants put their energy into flower production in order to attract insects like honeybees. Once the flowers get pollinated, plants begin producing seeds.
If you cut away dead flowers before they go to seed, zinnia plants continue dedicating energy to bloom production.
Deadheading lets you enjoy beautiful blossoms all season long. Without it, you’ll get only a flash in the pan of stunning colors followed by sad, dried-up plants.
Zinnias are vigorous and one of the easiest flowers for beginners to grow. If you have never tried growing this beautiful flower, you can purchase an all-in-one zinnia growing kit online.
Why Deadheading Zinnia is an Essential Process
Zinnia flowers are ideal for first-time gardeners. Zinnia care is easy even when it comes to deadheading since these plants are quite resilient.
You can start deadheading as soon as the flowers mature. This is a great option when you plan to collect the flowers into a bouquet or arrangement.
If you don’t intend to utilize the clipped flowers, you can wait to deadhead zinnias until the blooms begin dying.
Once the brighter color dulls and browns, it can look rather unattractive in your flower bed. You will probably feel compelled to remove them anyway!
In essence, plucking these dead zinnia flowers is the idea behind deadheading. The deadheading process halts the transition from flower to seed.
After clipping the dying blooms, flower buds quickly emerge to replace them. This leads to a greatly extended bloom time and more colorful zinnia flowers.
How to Deadhead Zinnia in 3 Easy Steps
It is simple to spot zinnia flower heads that are ready to pluck. Once the colorful double flowers on these annual plants start to look brown, it’s time to prune.
You don’t need to wait for the flowers on plants to look sad before you clip them. If you time it right, you can create gorgeous bouquets while deadheading zinnia.
Step 1: Spot Browning Flowers
Spotting dead flowers on healthy zinnia plants is straightforward. Look for browning flower petals and lackluster, fading blooms.
You can skip this first step if you plan to create flower arrangements. You’ll want vibrant-colored, cheerful blooms, so go ahead and cut them whenever you are ready.
Step 2: Pinch or Cut Flowers
First-time gardeners don’t need to be afraid of damaging leaves or killing these hardy plants. Zinnias are sturdy plants that can recover from nearly any gardening mishap.
A sterile pair of scissors is the most important protection you can offer zinnia plants. Cleaning your shears between plants reduces the spread of bacterial and fungal diseases, like powdery mildew.
You should also consider protecting yourself by wearing gloves when deadheading zinnia. These toxic plants contain a sulfur compound that can irritate skin and mucous membranes and may lead to illness if accidentally ingested.
You can alter the bloom height of the original plant through strategic deadheading. Taller varieties can be coerced to bloom nearer to the ground.
Clip the stem under the dead flower to as many feet tall as you want the next bloom to reach. This allows you to effectively use the deadheading process to create compact foliage that’s easier to manage.
Step 3: Repeat as Desired
You can continue deadheading all season as frequently as you want. If you have planted a wide array of colorful Zinnias, you can pluck these cheerful blooms every couple of days.
If you are diligent with preventing your flowers from going to seed, you can enjoy these beautiful blooms until late summer or early fall.
Unless you live in an area that stays warm and sunny all year long, you won’t be able to extend the life of your zinnia plants much further. Luckily these flowers produce a prolific number of seeds that are easy to harvest and grow.
