'dew' on leaves

Kevin · 11-16-2009, 12:32 AM

I have a Dwarf Orinoco that was outside during the summer, and is inside in a pot now. I have noticed 'dew' drops on the edges of the leaves. Is this normal? Okay? What causes it?

moonboy87 · 11-16-2009, 12:37 AM

I've noticed that with my gran nain as well. Especially new leaves tend to have dew on the tips as they grow. I have always just assumed that it is a result of the humidity and change in temperature in my apt though.

I think dew on leaves is natural, especially on banana leaves. I find dews on banana leaves every morning.

sandy0225 · 11-16-2009, 08:59 AM

it means the plant is happy and getting plenty of water.

djmb74 · 11-16-2009, 09:00 AM

if you taste it and it has a citrus flavored carbonated soft drink after taste that can be a problem. Otherwise should be fine!

moonboy87 · 11-16-2009, 02:51 PM

What would that mean Martin?

djmb74 · 11-16-2009, 03:09 PM

it was a silly joke... "Dew" Mountain Dew....

LilRaverBoi · 11-16-2009, 03:20 PM

I'm pretty sure you're referring to 'transpiration.' Basically, water enters the roots and when the plant reaches a high enough moisture content, (probably has something to do with humidity in the air as well) the leaves lose water out of stomata in the leaves. This is usually noticed as droplets of water on the edges of leaves, especially in the evening time. Someone correct me if the details here aren't quite right....I've never taken botany, unfortunately since it wasn't offered at any of the schools I attended. Just know a bunch of plant crap from my own private research/interest in the topic.

jmoore · 11-16-2009, 03:26 PM

Yep, what raverboi said. Dew is perfectly normal

Thanks everyone! If this is transpiration, then why do we not usually see this same thing on all other plants? Are bananas different this way?

LilRaverBoi · 11-17-2009, 01:25 PM

It happens to nearly all of my plants that I have in my room with some frequency...bananas, alocasia, colocasia, spider plant, etc. Might be that they're being watered differently and also, some plants tend to do this more than others. I know one night the bananas were all dripping repeatedly onto the floor like it was raining!

deruo · 11-30-2009, 03:12 PM

You have no idea how much a relief it was to find out that banana plants do this.

I had a new one indoors this summer and I kept seeing water spots on the leaves. Strange... I hadn't misted it that day.

Oh no... the roof is leaking!

I spend a good half hour inspecting the drywall on the ceiling, the carpet underneath the plant, going up on the roof and removing patio furniture, decking and inspecting the roof membrane. All dry.

Then the water spots stopped, or at least weren't as prevalent.

At least I got a good workout from it.

This is close, but not quite. Water that leaves through the stomata via transpiration is in a gas phase and simply disperses into the air. What we see happening with the bananas is called guttation, and it is excess water leaving through pores at the leaf margins called hydathodes. This happens because at night the stomata are closed and transpiration does not occur (water leaves the plant via the stomata during the day), but if there is still an excess of water at night that needs to leave the plant (because the soil is too wet), it leaves via the hydathodes as water droplets. It is not a sign of anything bad and should not be of concern. Its just one of many ways plants can deal with an environmental situation.

Guttation is also not be confused with dew, which is atmospheric water that condenses on the leaf surface.

Tony O · 12-12-2009, 09:47 PM

Just my 2 cents. If you have a white, or light color carpet, the droplets can leave a dark stain.

LilRaverBoi · 12-12-2009, 11:47 PM

My Ice Cream is dripping tonight cause it's raining outside.....and now that it's big it's hanging over my bed! So my bed is getting dripped on by one of the leaves. Hope sleeping in there tonight isn't like Chinese water torture or something!

Leolady · 12-15-2009, 09:36 AM

I get the so called "dew" drops on my banana plants, but I am also getting what looks and feels like salt on the leaves. No, I haven't tasted it. LOL
Does anyone else get this also, and is it harmful to the leaves/plant?
