Your lamb's ear turning brown and mushy is almost always a sign of too much moisture. The plant hates wet feet and damp foliage, so soggy soil or a long humid stretch pushes it straight into rot. The good news is simple. Get the water under control and most clumps bounce right back.
The damage has a clear look. After a humid spell or heavy rain, the center of the clump caves in. Those middle crowns go soft, brown, and slimy to the touch. Meanwhile the drier outer edge keeps its silver fuzz and stays firm. That contrast is your first clue. The wet, packed core failed while the airier rim survived. So you are not looking at a dead plant. You are looking at a drainage and airflow problem with a soft center.
Behind that collapse is lamb's ear root rot. Soil that stays wet day after day starves the roots of air and lets fungal pathogens move in. The rot then climbs from the roots up into the crown, which is why the heart of the plant turns to mush first. By the time you notice brown leaves on top, the trouble has usually been brewing below the surface for a week or more.
The fuzzy leaves make all of this worse. That woolly silver coat is built to reflect harsh sun in a dry garden, but it also traps water like a sponge. Damp, fuzzy leaves give fungal disease the moist surface it loves. You end up with lamb's ear mushy leaves, dark leaf spots, and a gray dusting of powdery mildew sitting on top of the crown trouble down below. One wet patch can spawn three problems at once.
The sourced research backs this up. Texas Tech notes that lamb's ear has a low tolerance for humidity and recommends good airflow to keep the leaves dry. UW-Madison points to excessive moisture as the trigger for crown meltout, which is the soft collapse you see right in the middle of the clump. Both come back to the same root issue. Wet plus warm plus poor air equals rot, every time.
Once you spot the pattern, act fast before the rot spreads through the whole bed. Start by cutting overhead watering so you stop soaking the leaves from above. Then dig in and remove the damaged tissue with a clean knife. Cut each rotted crown back until you reach firm, pale tissue with no brown streaks running through it. Anything that feels soft or smells sour has to go. Leaving even one slimy crown gives the rot a fresh head start next time it rains.
After that, give the survivors a drier home. Open up the airflow so the leaves can dry within a few hours of rain. Improve the drainage in that spot too. Then replant the healthy rosettes a little higher or on a gentle slope. Water will run off instead of pooling around the crowns. A raised, breezy position is the single best defense against a repeat.
Diagnosis is the part to nail here, and you have it now. The deeper fixes for watering habits and soil drainage live in the main guide, so lean on that page for the full routine. For now, treat the brown mush as a moisture alarm rather than a death sentence. Dry the plant out, give it room to breathe, and your lamb's ear comes back silver and tough within a season.
