Underwatering and Low Humidity

Lamb's Ear has a high surface area due to its fuzzy texture, which leads to rapid transpiration. When soil moisture is insufficient, the plant cannot transport enough water to the extremities, causing the soft leaf tips to desiccate and turn brown.

Very Common

How to confirm: Check if the soil is bone-dry several inches below the surface and if the leaves feel crispy to the touch.

Salt Accumulation (Fertilizer Burn)

Excessive mineral salts from fertilizers or hard water can accumulate in the leaf tissue. This osmotic stress draws moisture out of the cells, typically manifesting as scorched, brown edges on the silver foliage.

Common

How to confirm: Look for white, crusty deposits on the soil surface or the edges of the pot.

1 Flush the soil thoroughly with distilled or rainwater to leach out accumulated mineral salts from the root zone.
2 Prune away the most severely scorched leaves to prevent further aesthetic decline and use a moisture meter to ensure you are not overcompensating with water.

Fungal Leaf Spot (e.g., Botrytis)

While Lamb's Ear is relatively hardy, high humidity and wet foliage can encourage fungal pathogens. This often begins as brown or dark patches on the leaf tips that may eventually spread to the rest of the leaf.

Common

How to confirm: Inspect the undersides of the leaves for any visible fuzzy mold or dark spotting.
