The Q&A Archives: When to Plant Gladiolas

Question: I read the question about planting Glads in early spring. The person who asked the question was from CA. For our climate in PA, would it be bad to plant them in June? Would this time of year harm the bulbs in any way? Should we wait for another time? And, if so, how should we store them?

Answer: June is fine! You can start planting glads in the spring, say mid to late April. Plant some every ten days or so for a continuous show all summer. They take between 70 and 100 days to bloom, with smaller corms taking longer than larger ones. To store them, keep them dry, dark, and cool (but not freezing).
