Should I Mist It?

[big rockpile]

My Peace Lilies haven’t bloomed until the humidity got high.

I was wondering if they should be misted every so often?

Yes.

 

[Sluggy]

Definitely.

Is humidity a key to them blooming?

Is humidity a key to them blooming?

Well I went through a long time with no blooms.

The humidity has been high last couple months so I read up on this plant.

Everything has to be just right and humidity is one thing it needs.

I moved one to my Bedroom and it has about 8 blooms.

But they came from understory of a Rain Forest loving high humidity and moist soil. Not much sun.

I have to keep my bedroom door open or fans running to keep the humidity down while I sleep or the room gets very humid even making the walls and ceiling wet.

I imagine the plants like the bedroom for the humidity we create while sleeping. I understand not everyone is like me but I think we all exhale humidity. And co2. The bedroom sounds like a perfect place for peace lily.

Well Lily is happy other than my Fan but I mist her so I get a pass.

Major argument. She keeps turning her blooms green so I cut them off.

And tell her White.

I’ve noticed the same thing with peace lilies. They seem to really appreciate higher humidity, but I wouldn’t rely on misting alone to keep the humidity up. The effect of misting is pretty short-lived, especially if the room is dry.

If yours are blooming once the humidity rises, I’d focus more on keeping the overall conditions consistent. A humidifier nearby or grouping plants together usually works better than spraying the leaves every day. Occasional misting shouldn’t hurt, but I wouldn’t expect it by itself to make a peace lily bloom.

Light is important too. They can tolerate lower light, but if you want flowers, bright indirect light usually makes a noticeable difference.

Light is more important than humidity. It is more important than almost anything else.

Misting will not hurt them, but it is not what got them blooming. It raises the humidity in a thin film of air at the leaves for a few minutes and then evaporates. A room at 30% humidity is not meaningfully wetter because you misted a plant that morning. The one real risk is water sitting in the leaf bases and the crown, which rots peace lilies, so if you do mist, mist the air around the plant and not the foliage.

What does raise humidity: grouping plants together, a wide tray of pebbles and water with the pot sitting above the waterline, or a humidifier, which is the only one of those that moves the number much. If the plant is near a heater or an air conditioning vent, moving it does more than any amount of misting.

On the bloom, I would look at light before humidity, as cpp gardener said. Peace lilies flower on light, and the usual reason a mature one does not is that it sits further from the window than it wants. If the humidity went up at the same time of year the days were getting longer, it is easy to credit the wrong thing. Feed matters too. One that has not been fed for a year often has plenty of leaves and no flowers.

So no, they do not need misting. Bright indirect light close to a window without direct midday sun on the leaves, compost kept evenly moist rather than dried right out and then soaked, and a light feed through the growing season. Skip the spray bottle if you would rather.
