Gladiolus is a popular flowering plant that produces tall spikes of colorful blooms. When planting Gladiolus bulbs, it is important to space them properly to ensure optimal growth and flowering. A general rule of thumb is to space the bulbs 3-4 inches apart, with a depth of about 4 inches. But this depends on the personal preference of the gardener.
However, if you are planting Gladiolus mixed, the spacing may vary depending on the size of the bulbs and the desired effect. Larger bulbs can be spaced slightly further apart, while smaller bulbs should be planted closer together. A spacing of 3 to 4 inches is generally recommended for mixed Gladiolus bulbs. Additionally, make sure to plant them in a sunny, well-draining location for best results.
