hi - new to gladiolas and am wondering about the stem after the plant has bloomed. it looks as if the stem is producing something where the buds were. are these new corms ? i just assumed that new corm production would occur underground ? i thought that i would leave the stems to see what it would look like with a dozen or so. is it ok to leave them or should i cut. there are other plants around them and i don't want to rob them of nutrients if leaving the stems will do that ? - thanks, brian
