What to do if a Peace Lily won't bloom? Causes and solutions

The Peace Lily (Spathiphyllum, a member of the Araceae family) is a perennial herbaceous plant of the genus Spathiphyllum. Many flower lovers don't know what's going on when their Peace Lily won't bloom, because the Peace Lily is primarily a foliage plant, but some flower lovers are very eager to get their Peace Lily to bloom. Let's take a look below at what to do if a Peace Lily won't bloom!

What to do if a Peace Lily won't bloom

To get a Peace Lily to bloom, the first thing to consider is light. Although the Peace Lily is very shade-tolerant, it is very difficult for it to bloom if it stays in a very dark place for a long time. However, it should not be placed under blazing sun either; bright indirect light is most suitable. In addition, a certain amount of fertilizer must be ensured. If the potting soil is too poor, it is not conducive to blooming either. In winter, it is best to provide sufficient light, which not only helps the leaves stay deep green but also helps the plant overwinter.

You can induce a Peace Lily to bloom by spraying gibberellic acid, using artificial means to induce the plant to flower. Different varieties bloom at different times: small varieties respond more quickly to gibberellic acid and can bloom 7-9 weeks after spraying, medium varieties need 10-11 weeks, and large varieties need 12-13 weeks. Note that too high a concentration of gibberellic acid will cause the plant's flowers to become deformed, so generally a dilution of 1000-1500 times is sufficient.

What to do if a Peace Lily flower turns green

Many flower lovers find their Peace Lily flowers have turned green and don't know what's going on. In fact, this is because the Peace Lily has reached the later stage of its flowering period and has more chlorophyll, so at this point it can be cut off so it no longer consumes unnecessary nutrients. In addition, if a Peace Lily flower turns green just a few days after opening, this is not a natural phenomenon; it is mainly caused by light that is too weak. Any white flower color will show a greenish tint under weak light conditions. At this point, simply increasing the light intensity a little will turn it back to white.

A Peace Lily only grows leaves and won't bloom

1. Unsuitable light: if a Peace Lily stays in too dark a place for a long time, its growth weakens and it is not easy for it to bloom; while if the sunlight is too strong and direct, the leaves may turn yellow.

2. No repotting: the Peace Lily grows relatively quickly, and generally after 1-2 years its plant will fill the pot, with crowded leaves making it hard to bloom. Therefore, it needs to be repotted in time, and usually after repotting it is best placed in partial shade.

3. Insufficient humidity: the Peace Lily requires high humidity, and when the air is too dry it is unfavorable for blooming. Each watering should be thorough to keep the potting soil moist.

4. Lack of fertilizer: not fertilizing for a long time is not conducive to healthy plant growth. During the growing period from May to September, apply some granular compound fertilizer each month, so that it will both grow leaves and bloom.

5. Compacted soil: the Peace Lily requires loose, well-drained, humus-rich sandy loam to facilitate drainage and aeration.
