Gladiolus, popularly known as the sword lily, is an iris-related flowering plant. Although it is native to South Africa, it is widely cultivated throughout the world for its showy and long-lasting blossoms. Gladiolus plants are distinguished by their tall, spiky branches that carry numerous huge, brilliant blooms. They bloom in the summer and autumn and come in a variety of colors such as white, yellow, pink, red, purple, and orange.
Gladiolus plants are excellent for cutting flower bouquets, landscaping, and garden borders. Because of their exquisite and dramatic appearance, they also become a popular choice for special occasions such as weddings. This comprehensive guide will show you how to grow and care for it as well as some pictures of gladiolus flowers!
How to Grow Gladiolus
Sword lilies are simple to grow and thrive in well-drained soil with full sun. Because they require a long growing season to produce blossoms, they are best planted in the spring or early summer.
To plant gladiolus, pick a sunny spot in your yard and enrich the soil structure and fertility by adding compost or well-rotted manure. Then, dig a hole double the width and depth of the gladiolus corm (a type of underground stem). Place the corm in the holes and cover it with earth, firming it down slightly. Carefully water the soil to assist the corm settling in and limit the possibility of rot.
Planting gladiolus bulbs in pots: Gladiolus plants may also be grown in pots or containers, as long as the pot is large enough to hold the root system of the plant. Utilize a well-draining potting mix and give the plant plenty of sunshine and water. You can scroll down for more images of gladiolus flower!
How to Care for Gladiolus
Gladiolus plants need to be watered on a regular basis, especially during dry seasons. Water the plants thoroughly to keep the soil equally moist but don’t overwater them as this might cause rot. Fertilize the plants with a balanced liquid fertilizer every two to three weeks to ensure healthy development and plentiful blossoms.
Pests and diseases that affect gladiolus plants include aphids, snails, and rust. Keep an eye watch for any indications of infestation or sickness and take appropriate steps to avoid these problems. To avoid the spread of the problem, you might, for example, use a natural pest repellent or remove the afflicted leaves.
The Best Condition for Gladiolus Development
Gladiolus plants prefer full sun and well-draining soil rich in organic content. They also thrive in warm weather, so put them somewhere that gets plenty of sunlight and is protected from strong winds.
Provide your gladiolus plants with the proper quantity of water, fertilizer, and sunlight to guarantee that they develop and flower to their greatest potential. Water the plants on a regular basis, but avoid overwatering, and fertilize them every 2 to 3 weeks with a balanced liquid fertilizer. Plant the corms in a sunny spot that receives at least six hours of direct sunlight per day.
Common Species Of Gladiolus
Here are some additional details on some gladiolus species:
- Gladiolus Communis, generally referred to as common or wild gladiolus, is a European native with long spikes of white or pale pink blooms. It can reach a height of 4 feet and has sword-shaped leaves.
- Gladiolus Dalenii, often known as parrot gladiolus or bush gladiolus, is a South African native with bright orange or red flowers. It can reach a height of 2-3 feet and has short, grass-like leaves.
- Gladiolus Murielae, often known as the peacock gladiolus or Mediterranean gladiolus, is a Mediterranean gladiolus with deep purple or blue flowers. It can reach a height of 3 feet and has short, grass-like leaves.
- Gladiolus Tristis, often known as the weeping gladiolus or sand gladiolus, is a tiny, yellow or white flowering plant native to South Africa. It can reach a height of 1-2 feet and has short, grass-like leaves.
- Gladiolus Carneus, often known as the fleshy gladiolus, is a South African native with pale pink or white flowers. It can reach a height of 3-4 feet and has short, grass-like leaves.
How to propagate Gladiolus?
Gladiolus can be propagated in a variety of ways, including dividing the corms (bulbs), planting cormels (little offsets that occur on the margins of the corms), and planting gladiolus seeds. Here’s an overview of each method:
Corm propagation: This is the most prevalent way of gladiolus propagation. Dig up the corms gently in the fall or early spring and separate them into smaller corms, each with a few growth points (eyes). Plant the corms in well-draining soil three to four inches deep, with the growth points facing upward. Water the corms thoroughly and keep the soil moist until they sprout.
Cormel propagation: Cormels are tiny offsets that occur on the sides of corms. After the threat of frost has gone, they can be uprooted and replanted in the spring. Plant the cormels approximately 1-2 inches deep, growing tips up. Water them thoroughly and keep the soil moist until they sprout.
Gladiolus seeds might be sown directly in the garden when the threat of frost has gone in the spring. Sow the seeds approximately 1/4 inch deep and thoroughly water them. Maintain moisture in the soil until the seeds germinate, which normally takes around 2-3 weeks. Seeds can also be started inside in pots in late winter or early spring.
FAQs
Can I leave gladiolus bulbs in the ground?
Gladioli is winter hardy in USDA Hardiness Zones 7 and above, which implies their corms could be left in the soil all year. Most gladioli corms must be dug out in the fall, kept, and replanted the next spring in Zones 6 and colder.
How long do gladiolus bloom?
Gladiolus flowers last around a week, though they can last for two weeks. The lower buds open before the upper ones. This short flowering period is why many gardeners plant gladiolus corms in succession in spring and into summer, usually once every week or two, in order to get a continuous show.
Do gladiolus come back every year?
Gladioli can return year after year, but depending on where you live, they may need to be elevated or covered throughout the winter. If they do not bloom the cause could be soggy soils or a shady location, and the corms can also be devoured by animals.
When to dig up gladiolus bulbs?
It is ideal to dig up your gladioli bulbs in the autumn, around 6 to 8 weeks after flowering has ceased. The fundamental reason for this is that when the soil is cold and damp during the winter, or if there are significant frosts, the weaker bulbs will die out, allowing the dominating colors to take over.
How long for gladiolus bulbs to sprout?
Gladiolus might be planted 2 weeks before the last anticipated spring frost. It will take between 70 and 90 days from growing to flowering.
What to plant with gladiolus?
Gladiolus pairs well with dahlias, peonies, and other hardy perennials that might maintain these tall, petal-packed flower spikes. If you want to cultivate gladiolus for cut flowers, put the corms in rows like you would vegetables.
How to keep gladiolus from falling over?
If you choose to plant your gladiolus in rows, set a stake at each end of the row and then run some sturdy twine or fishing line down the entire row. Place 3 or 4 stakes along each clump of grass if you are growing them in clumps, then twine around the flower.
When to cut back gladiolus?
Once the leaves die and turn yellow in midsummer, cut them off at the ground. Although it may seem alluring to remove the withering leaves early, doing so will prevent the corms from receiving the nutrients the leaves produce through photosynthesis. At this stage, you can also trim back any residual stems.
How to care for gladiolus after they bloom?
Feed them with a liquid fertilizer every few weeks once the blossom spike appears. Gladioli in pots need to be watered regularly during the growing season since they dry up more rapidly than those planted in the ground. When the leaves start to yellow, stop spraying, lift the corms, and store them for the winter.
