What is Aging Bloom and how to prevent it?

When the spathes of peace lily get old, they turn green and also make the white flowers green. They are the bracts that surround the spadix where flowers grow. When the higher amount of chlorophyll triggers the plant to make more energy. This also triggers the plant to make the flowers green.

Scientifically peace lily does not have flowers. It has spadix that is called the flower of the plant.

At the very first stage, you have to choose the best healthy plant from the local garden store. Look for the signs of plant aging and dying blooms. Do not buy such plants.

Young plants stay healthy for a long time because they have young spathes.

Garden stores use Gibberellic acid to encourage heavy white bloom in peace lily flowers. They do this to impress buyers. But once the bloom over after few months. The next bloom comes weak and does not stand for a long time. Tell the garden store representative that you do not need a peace lily plant that is treated with this acid.

Light and Green flowers of peace lily

Light is the second common reason for peace lily flowers turning green in color. Low light will also trigger green color bloom. One to two days of low light will not affect the plants. But if the peace lily plants continuously stay in low light, then this increases the chances of having green flowers.

In low light conditions, the plants become unable to produce their food. The green parts of the plant produce chlorophyll to make plant food. In low light, the spathes start producing chlorophyll to help plants to full fil its chlorophyll needs.

When the spathes make chlorophyll, they turn into green color which makes the spadix also green. In low light, all peace lily plants use spathes to produce chlorophyll even they only produce a limited amount of it.

Caution: Do not put the peace lily in low light right after purchasing it.

Some growers think that bright light causes green leaves in peace lily. But this not true at all. Direct sunlight or high intense indirect bright light burns the leaves.

Because it needs a high amount of it to make plant food.

This light is similar to the sun rays but they are not high intensity. Plants cannot differentiate between natural light and light emitted by grow lights.

Install grow light 2 feet above the plant and under one light you can grow many plants. If you have 200 watts grow light. You can grow 3 peace lily plants under it. The best part is you can grow other plants under the same light if you want some change in your plant collection.
