How deep should I plant gladiolus bulbs?

Question:

How deep should I plant gladiolus bulbs?

Answer:

Planting depth varies with the size of the bulb (corm).  Large corms should be planted 4 to 6 inches deep and 6 inches apart.  Small corms should be planted at a depth of 3 inches.  Gladioli require well-drained soils and perform best in a sunny location.  Gladiolus bulbs normally bloom about 8 to 10 weeks after planting.
