Hi. For 5 years I have had a wonderful show from my gladioli, but this year nothing - not a hint of flower on any of my plants. I was very late planting them out this year due to the bad weather we had - about a month later than normal. But I am concerned that not one of the plants is showing signs of flowering, neither are they dying back! I always dig them up each winter and store them in my garage. This year I don't know what to do with them for the best to try and ensure flowers next year. Shall I leave them in the ground and hope the frost doesn't kill them so they maybe get more nutrients over the winter or just cut them back and store and hope for the best next year?
