Thin those overgrown glads

QUESTION: I have a bed of gladiolus in my condo courtyard. The plants have grown so thick that they look crowded and messy, falling over each other. I know I need to thin them out, but when? And how?

glads redGladiolus grows from a tender corm, and in cold climates, garden experts suggest digging up the corms in the fall and storing them over the winter. In Middle Tennessee, I doubt that many gardeners go to the trouble. Winters here are just not that cold, and the glads pop up with no problem in the spring.

But you can still dig them up in the fall for the purpose of thinning them out. Whether you’re lifting them out for winter protection or for thinning, the University of Tennessee   Extension suggests digging them up on a bright, sunny day in the fall, after the foliage dies back but before a heavy frost. Cut the foliage flush with the corms and dry them outdoors during the day, but move them to a warmer, well-ventilated area to continue drying.

After a week or two, the old corms should separate from newly produced corms; gently pry them apart and discard the old one, along with any that are diseased or scarred. Dry them in a warm place for a few more days, and when they are cured, store them in a cool, well-ventilated area through the winter.

Next spring, put the corms back in the ground. You only get one flowering stem per corm, but you can stagger the planting over several weeks to have a succession of blooms – the Extension office suggests planting at two-week intervals, beginning in late April or May and ending no later than 60 days before the first frost to provide flowers from about mid-summer and into the fall. Plant corms 4 to 6 inches deep. Taller varieties may need to be staked as they grow to prevent the top-heavy flowers from toppling.
