How to remove dead Peace lily flowers?

Spathiphyllum flowers, known for their unique appearance, are often questioned by new Peace Lily owners about the need for deadheading. However, deadheading is beneficial for Peace Lilies, as they last around a month after unfurling and turn brown and shrivel up. Once this happens, the dead flowers should be removed near the plant’s base using clean, angled cuts with disinfected shears. Deadheading not only enhances the plant’s appearance but also invigorates it and encourages fresh new blooms. The best way to remove dead Peace Lily flowers is to follow these recommendations.

Your Peace Lily’s growth requires an investment of energy, with each leaf, root, stalk, and blossom representing an investment. Flowers are particularly expensive as they do not contribute income, photosynthesize, absorb nutrients, or store energy. There is a limit to how many flowers a Peace Lily can support at once, and once a bloom forms, the plant must spend energy on maintaining it. Deadheading, or cutting off dead flowers, allows the plant to grow faster and frees up energy for fresh new flowers. Deadheading also helps the plant bloom more often, as it frees up part of the energy budget for fresh flowers. Dead blossoms are not very pretty and can be removed to make the Peace Lily look like a snack again. By removing dead blossoms, you can save energy and reduce the energy consumption of your Peace Lily.

How to Know When a Peace Lily Flower Dies

This text provides a comprehensive guide to the life cycle of a Spathiphyllum bloom, allowing readers to understand how to deadhead a Peace Lily when the flowers begin to die off. Each blossom on a Peace Lily is arranged on a separate stalk, with the white “petal” wrapping around it in a twisted cone shape. The spadix, a bumpy spike, protects the flowers as they develop. The tiny flowers grow in rows along the stubby cylinder at the center of the bloom.

The spathe, a characteristic hood behind the spadix, takes a while to unwrap and form its hood. It is in the female phase for 4-5 days, with fuzzy cone tips opening to receive pollen. After this, puffy, wispy anthers pop up between the spadix bumps, appearing dusty and swollen. This phase lasts another 4-6 days. The bloom stays healthy and white for another week or two after the male phase ends. If the plant is in good shape, the flowers may last up to two months after unfurling. The spathe will turn green, brown, sag, and crumple, indicating that it’s time to deadhead.

How to Remove Dead Peace Lily Flowers

Deadheading a Peace Lily is a simple process that requires only a few supplies. First, use pruning shears to remove the dead flowers when they are just starting to turn brown. Disinfect the blades with rubbing alcohol, hydrogen peroxide, or 1 part bleach in 9 parts water to remove bacteria that might cause the plant to become sick. If you are not sensitive to the plant’s juices, gloves may be necessary.

Sanitize the shears and remove the thin stalk holding up the dead flower, as it won’t produce new leaves or blooms. Cut the cut at a 45-degree angle to reduce the likelihood of water droplets collecting on the cut end and incubating fungal infections. Repeat this process, disinfecting each time, until you have removed every spent bloom. Be sure to scoop out any plant parts that fall into the pot to prevent the spread of fungus gnats. This will help protect your Peace Lily from pests.
