Brown spots on leaves

10ft to light, indirect
8” pot with drainage
Last watered 3 weeks ago
Rattlesnake Plants are Calatheas, like Prayer Plants, and these plants are very particular about their water, often getting brown spots with unfiltered tap water. This could be your issue. Try watering it with filtered, distilled, or rain water, if possible.

Good luck!

I've been watering my Rattlesnake plant with distilled water for 2 years and he has the same brown rust-looking spots. These starting appearing about 3 months ago.
The problem is not the water!

I could use help....like Cliff.
Thanking everyone in advance πŸ€—πŸ˜

I think this is some kind of fungus or bacteria, I am not quite sure. I used to get this on my Makoyana during winter, and as I cut away the leaves, new healty ones arrived in spring and summer. Untill the spots emerged again in winterπŸ€·β€β™€οΈ

I heard someone call it kind of a "cold", as they are more susceptible (in my place) in winter (as the weather is cooler, inside air is dryer, and less light). And I really feel that it fits.

So your plants might be just a little stressed out, just enough for the bacteria or fungi to take a little hold. I am not sure of the treatment though πŸ™ˆ Mine kind of went away as the plants grew older and stronger (and I got a humidifyer during winterπŸ€”) Maybe @DreamMachine knows❀️

If you are misting the plants, please stop, as the droplets makes it easier for infections to take hold πŸ˜‰

Hi Veronika!

Thanks for responding... πŸ€—

So...my Rattlesnake has always been in the same spot from when he was a baby.
I never ever mist ANY of our plants and am careful not to splash water on their leaves.
Just in case, as I usually do, am going to make sure that he's almost completely dry before watering and...will switch back to bottom watering to see if that helps.
Cliff & Joanie, that's too much water. You can allow rattlesnake plants to dry completely between watering. They are happier that way.

Here are my tips:

Calathea Care Tips

1. Plenty of indirect light. Direct sun will burn their leaves. Grow lights are great, I keep my collection under grow lights 12 hours a day.
2. Water when the soil is at least halfway dry. I all ow mine to go dry and they do great. Unless you have high humidity or a humidifier. If you have a high humidity environment let them go dry before watering again.
3. Keep temperatures stable. They hate fluctuating temps. Interior walls are best the temps there are more stable.
4. They love humidity a humidifier is great. I increase humidity with pebble trays below the plant so as the water evaporates it increases humidity. I also cluster them together so they create humidity themselves.
5. Ceramic or porcelain pots are best. Terracotta and plastic are bad. Terracotta is terrible for these because it pulls moisture away from the roots. Plastic does not give the plant aeration so the roots will lack oxygen. Without oxygen the plant loses its ability to absorb water and nutrients.
6. Only us distilled or rain water. Player plants are very sensitive to the chemicals in tap water.

Hi!
Thanks so much for responding!
So...Shannon, I do and have done everything you listed.
These rust-looking spots just popped up recently.
Someone suggested it might be fungal?
Rub the spots with your fingers. Do they leave a residue? It would be orange, brown or even a bit yellowish on your fingers. @CutePolypremum
@SuperbRaspfern
Good morning!
No...it does not rub off on my fingers and leaves no residue.
That's good Joanie, definitely not rust. I say overwatering because when temps dip for a week. A couple of mine will get spots like that. I ease off the water and then good as new. No new spots. @CutePolypremum
@SuperbRaspfern

YAY!!!!!!!

THE HUGE MYSTERY IS SOLVED!

Thanks SO MUCH, my dear friend Shannon.
You always end up saving the day.
I'm very relieved πŸ˜πŸ˜˜πŸ˜‚
@SuperbRaspfern @CutePolypremum
That’s really interesting. I should keep that in mind after it cools though. I keep my rattlesnake plant outside in north Florida, on our patio that has a lot of tree cover, and they seem to stay thirsty. I guess this heat will do that.
@LaneyLichen Yep plant stress outdoors will definitely do that.
