Growing Gladiolus

Spacing: 6", Depth: 4-6", Full Sun

These beautiful flowers grow well in the same conditions that most garden vegetables prefer, which is average, well-drained soil that is slightly acidic (a pH of 6.0 to 6.5). Good drainage is essential. Use a fertilizer that is lower in nitrogen, such as 5-10-5, to encourage flower production rather than excessive leaf growth.

Plant the corms outside as early as a month before the last spring frost in your area, or at two week intervals from then until late June in order to produce a succession of bloom.

Gladiolus require water throughout the season, so if there is not sufficient rainfall, water them deeply once a week (provide 1in of water).

To save the corms for the following year, dig them up before the first frost date, wash soil off, and cut the stems to within ½" of the corm. Dry the corms for 2–3 weeks in a warm, airy place. Store in mesh bags (or old nylon stockings) at 35-45°F in a well-ventilated area until time to replant.
