White tissue
It contains less chlorophyll than the green part of the leaf, so it dries and scorches more easily.
Symptoms on popular plants
Browning white sections on Monstera Albo
White tissue has little chlorophyll and is more vulnerable to harsh sun, drought and root stress.
Edge of the mark
A crisp tan margin fits drought stress or harsh light better than wet rot.
Whole-plant health
Green tissue, roots and the next leaf reveal more than one damaged white patch.
More useful detail
How to narrow down the cause
What supports this cause
Browning confined to white sectors, with firm roots and healthy green tissue, is usually physiological or cosmetic.
What can look similar
Soft dark marks spreading into green tissue may have another cause and call for a moisture and root check.
Problem
What to do step by step
- 1
Photograph the edge of the brown area and compare it several days later.
- 2
Check moisture through the root ball and the leaf's distance from glass and heat.
- 3
Stabilize watering and light without removing healthy green tissue.
Observation
What to watch next
- New white sections remain firm for longer.
- Browning does not spread into green tissue.
- Roots and the stem base stay firm.
Important
Do not remove healthy green tissue simply to eliminate cosmetic browning.
