How To Keep Calla Lilies Looking Fresh While Blooming This Summer

0 4

Clipping calla lilies for cut arrangements and deadheading them is pretty similar, save for timing. In the former, you take charge as the flowers are opening, while for the haircut, you time it to when they begin discoloring, drooping, or curling inwards. Some cultivars may appear noticeably green or even brown if far out in their prep for fall dormancy. As mentioned, you don’t want the plants to go to seed.

Since certain calla varieties, such as Zantedeschia aethiopica, can irritate the skin if brushed past, it’s best to don gloves before getting down to business. Grab a pair of sharp shears, squat down to reach the base of the dead flower’s stalk, and nick it clean. Pull out the spent stalk with your hands if the tools aren’t handy, ensuring the adjoining new buds or leaves aren’t injured. In some cases, it may prolong the flowering period. While it’s fine to cut back any yellowing foliage, the rest should be watered and fertilized until it withers naturally under pressure from cooling temperatures. This practice will enhance plant vigor and aid it in building higher food reserves that can be directed toward building sturdier rhizomes for the next season.
