What happens if you leave gladiolus in the ground? However, if you leave them in too long, the bulbs will get frost damage. Do not dig up your gladioli bulbs before the foliage has died. The reason for this is that the plant will not have stored enough energy inside the bulb until the foliage has died back. Take care not to damage the bulb itself when digging up, too.
How many times will gladiolus bloom? Gladioli will only flower once per season, for around one to three weeks depending on the variety. For this reason, it’s best to plant a handful of bulbs every couple of weeks in late spring/early summer for a longer-lasting display.
Do you cut back gladiolus after they bloom? Remove the entire blooming stem once all the buds on the stem have opened and faded. To complete this step, use pruners or shears to cut the stalk near the ground. Don’t remove the leaves; this step comes later in the season. Removing the foliage too early can affect the plant’s ability to bloom in the future.
