Brown Spots on prayer plant
What's Happening
Misidentification of normal ontogenetic leaf coloration as disease. New Maranta leaves often emerge with isolated reddish-brown spots or patches between the veins. These are rich in anthocyanins for UV protection and naturally fade or darken into the characteristic dark green mature pattern as the leaf hardens.
How to Fix It
- 1
Observe new growth for 10-14 days without chemical intervention.
- 2
Verify that spots are firm and not soft or spreading (which would indicate fungal issues).
- 3
Avoid applying fungicides to healthy new leaves, as this can cause chemical stress.
How to Prevent It
Study growth-stage photo guides for Maranta leuconeura; maintain consistent humidity to support smooth leaf unfurling.
