Black Walnut Gladiolus Planting Instructions
Gladiolus is a genus of perennial bulbous flowering plants in the iris family. It is sometimes called the 'Sword lily', but usually by its generic name.
Black Walnut Gladiolus are a deep rich red color with black surrounding the edges of the blooms. Will add lots of drama to your garden. Just a gorgeous flower to not have in your garden collection.
Gladiolus plants are attractive, perennial herbs and semi hardy in temperate climates. All gladioli are easy to grow, colorful and make great cut flowers, hence their popularity. With very little work needed, your Gladiolus will burst into bloom in August, adorning your garden with bright colorful tall flowers that will make for a wonderful addition to any scheme.
Plant your Gladiolus in the spring, as soon as the soil has warmed up in March or April.
While they prefer full sun, Gladiolus will still grow well in partial shade. Gladiolus plants prefer a rich, soft soil, and plenty of water. If the soil is poor, add a little fertilizer to help stimulate growth.
The Gladiolus bulbs (or corm) can be grown in rows, or bunches. They will tolerate a little crowding, but will grow bigger if spaced out. We recommend planting the bulbs 8 inches deep - secured deep in the ground, you are less likely to need a stake. Plant them about 6 inches apart. If you have bought quite a few, don't plant them all at once. Stagger their planting and you will get a better succession of flowers. Add mulch to help retain water, and to keep the weeds down. Gladioli need plenty of water to flower well. On well-drained poorer soil, extra watering will be required. Once planted, your gladiolus should grow well with little attention.
