Hello,

I have this beautiful Stromanthe Magicstar 3 months now. A few days ago a few brown somehow dry spots appeared on the leaves. Also, I noticed that the plant gathers its leaves, mostly the ones from the bottom.
It is place near a window, but in a low light corner. I water it 2 times a week.

Can you please help with advice?

Thank you!

Too much water is causing the brown spots. Let the top inch dry well before watering again.
NOT A EXPERT! Just a grow worm! I never met a plant I didn’t love.✌

Please post a photo that shows the entire plant, including its pot, so we don't make incorrect assumptions. Also, a photo that shows its corner location might be helpful.

Is it still in its nursery pot and double-potted or did you repot it into the gray planter?

I re-potted it a month ago in the grey one. It has around 40 cm diameter, the plant came in one tat had around 25 cm.
The pot has a hole on the bottom, not too large though.
Thank you!

Because the new pot is so much larger than the old one, there is a substantially greater risk of inadvertently overwatering it. That is because the excess soil tends to absorb and retain water around the roots for too long.

Remove any soil you added to the top of the original rootball when you repotted as that soil prevents oxygen from penetrating the root zone readily and makes it harder to determine when to water. Then, allow the surface of the remaining soil to feel dry about a half-inch deep before watering.

Thank you for the advice!
Can I move it in a smaller pot, 30cm or I'll harm it?

That's a tough call. If you left the original rootball intact so that it can be recovered from its existing pot without disturbing the roots, then moving it back might be better for it long term. But if some of the original soil was removed, then it is better to leave it as it is and alter your watering routine as I described previously.

Thank you, Will! I'll keep it as it is. I removed a very little part of the soil, but better safe than sorry.
