The Q&A Archives: Planting Depths for Gladiolus, Mexican Shell Flower

Question: How deep should one plant gladiolus bulbs, Mexican shell flower bulbs and Chinese lantern tuber roots? Any helpful hints would be appreciated. Cindy Quinton Tulsa, OK

Answer: Plant gladiolus bulbs 4 inches deep in heavy soil; 5 to 6 inches deep in light, sandy soil. For use as cut flowers, you can plant as close as three inches apart in a row, with rows 18 to 24 inches apart. Plant in full sun for best flowering. Mexicanshell flower (tiger flower) bulbs should be planted 4-5 inches deep in sandy soil, 3 inches deep in heavy soil. Small bulbs should be planted shallower. Plant Chinese lantern roots about 4 inches deep--these plants are easy to grow and quite prolific, so don't worry too much about planting depth.
