When should you cut back gladiolus?

Can I leave gladioli in the ground?

As most varieties are not completely hardy, the corms are lifted and stored frost free for winter. In mild parts of the country you can risk leaving them in the ground – with a thick mulch over the soil – but it can be a risk. The corms are dug up after the first frost and left to dry for a few weeks.
