With very little work needed when compared to other bulbs, gladiolus flowers burst into bloom during the summer and decorate your garden with delightfully tall and colorful flowers. But how do you plant and grow gladiolus flowers in your own garden?
About Gladiolus Flowers
Gladiolus flowers are a genus of perennial plants (perennials can be regrown each spring) in the iris family. These tall, striking beauties are bulbous plants but don’t grow from a bulb. Instead, gladiolus flowers come from corms, a bulb’s closely related cousin.
The tall, spikey orchid-like blooms are sometimes called sword lilies due to their long, blade-like appearance. The flowering plants usually end up between 2 and 5 feet tall with flowers that can range from less than 3 inches to more than 5 inches across. The distinct narrow blade, or sword shape, of their deep green leaves gives them their name.
Gladiolus flowers come in such a wide variety that you are bound to find the perfect type for your garden vision. There are around 300 species of gladioli, ranging from flowers with plain petals to frilly and or ruffled petals. The floral displays come in every color: red, purple, pink, orange, yellow, white, and even multi-colored petals.
Depending on the species used to create the gladiolus hybrid, the blooms can take on three distinct shapes.
Most gladiolus hybrids come from these three parent species, but each type makes for a stunning floral arrangement.
Planting Gladiolus Flowers
Gladiolus flowers are versatile. You can plant them in your garden, raised flower beds, or large containers. For your gladioli plants to produce the best blooms, they need to be planted in full sun. While you can plant gladioli bulbs in shady areas, the colors will be less vibrant overall. They need 6–8 hours of direct sunlight per day to achieve the ultimate vibrancy.
When planting gladioli, you will need to loosen your soil, rake out the rocks and other debris, and try to add compost or manure. While not necessary, compost and manure will enrich the soil and improve the soil’s water retention, permeability, drainage, and aeration. Gladioli have the best performance in soil that is well-drained.
Lastly, depending on the size of the bulb, you need to space your bulbs 6–10 inches apart in your garden. If you have larger bulbs, they will need to be planted deeper into your soil, but on average, your gladioli bulbs should be about 2 to 6 inches deep.
When To Plant Gladioli Bulbs
Even if you have the perfect soil, you need to know when to plant gladioli bulbs. Gladioli are summer flowering plants; therefore, they need to be planted in warmer weather to give them the best bang for their buck.
You should only plant gladioli bulbs in the spring after the frost has passed and your soil has warmed up to around 55°F (13°C). If you want continuous blooming flowers through summer and early fall, you will want to plant your bulbs every 10 days to rotate their growth cycle. Depending on the variety of gladiolus you choose to plant, you’ll have flowered blooms within 60 to 90 days.
