Question
I live in zone 6, do i have to dig my gladolia bulbs and dry them every year? If so, when do I dig them and when do I replant them? Thanks for your advice.

Answer
Hi Tabatha,
Thanx for your question.  Gladioli (plural for gladiolus) are not reliably hardy in zones colder than Zone 7 although I have had some winter over in the backyard, during warmer winters here at the edge of Zone5/6.  I recommend digging up the corms after the first frost.  Shake off (do not wash off) dirt and cut off any dead foliage.  Store the corms in a netted bag in a cool, dry, dark place in the basement until after the first frost.  Plant 6 inches deep after the first frost and soil temps are above 60癋 (15-16癈).  The should start to flower about 90 days afterwards.  I hope this helps.
