Encouraging your peace lily to flower:
–
First off, you’ll be much happier if you take the perspective that you play a supporting role in plant growth as opposed to “how do I make the plant [do thy bidding].”
–
2️⃣ Take a look at how flowers emerge: peace lily flowers grow out of an established grouping of leaves. Based on my rough observations, the flower arrives on the back of the 4th or 5th leaf in a group – and there are many groupings within an entire pot.
–
So you’ll get more flowers if your plant is able to produce more of these leaf groups. How can you encourage the plant to produce more leaf groups?

Peace Lily production guidelines suggest 1500-2500 foot-candles for ideal growth but (1) we don’t necessarily want production level growth at home as it would be inconvenient to keep up with watering and fertilizing, and (2) only a greenhouse with adequate shade cloth could get 1500 foot-candles from directly overhead.

I’ve had my peace lily for over 6 years, getting consistently larger from a 6″ pot stepping up to 12″. Most of its time was spent with 200-600 foot-candles when the sun was NOT shining directly on the plant. In some of the places where it lived, it saw at most 3 hours of direct sun (measuring 3000-4000 foot-candles – that’s sun through a glass and at an angle). I water whenever I see the leaves droop a tiny bit and use 3-1-2 fertilizer whenever I see new leaves growing.

I love this Peace Lily as it is – flowers are just an occasional treat.

P.S. I purposely haven’t cut away the dead stuff so you can see that this is part of how it grows – I’ll clean it up soon.
