The Q&A Archives: Gladioli Plants Grew 10", Flowered And Flowers Withered

Question: I left a few gladioli bulbs in the soil after last summer while I pulled a bunch out from a large set. The remaining few bulbs have grew leaves and flowers since the last couple of weeks but the flowers have since started withering even before the plants and their stalks have reached full height. I suspect it is because the bulbs were not really healthy since I did not dig them up and store them away for the winter but I am not sure though. Any tips as to how to revive would help a lot. I am a novice gardner. Thanks.

Answer: Smaller corms will produce smaller plants and smaller flowers, so this could explain the small size. The cormels left over after removing the larger ones, or in the case of untouched corms, corms that have multiplied over the summer, will produce smaller plants due to crowding as well as smaller size overall.

Glad blooms would normally fade after a little while, and cold weather could ruin them as well.

There is one other possibility and that is that you have some of the small sized "hardy" glads that grow and bloom much as a spring flowering bulb would. These are left in place from year to year rather than dug.

At this point, remove the faded blooms and allow the foliage to grow all season so it can replenish the plant's strength.
