Aloe brevifolia Yellow Leaves - Causes & Fixes

error

Overwatering and Root Rot

Aloe brevifolia is a succulent that requires well-draining soil; excess moisture causes the roots to suffocate, leading to yellowing of the lower leaves as the root system decays.

Very Common

How to confirm: Gently pull the plant from its pot to check if the roots are brown and mushy instead of firm and white.

1 Immediately remove the plant from its current pot and inspect the roots; trim away any mushy, black, or foul-smelling roots using sterilized tools.

2 Repot the Aloe in a fresh, well-draining succulent mix and use a container with excellent drainage, such as a Root & Vessel cylinder pot, to prevent future water pooling.

3 Amend the new soil with perlite to increase aeration and use a moisture meter to ensure you only water when the soil is completely dry.

warning

Nutrient Deficiency (Nitrogen)

A lack of nitrogen prevents the development of chlorophyll, causing older leaves in the Aloe brevifolia rosette to turn a pale yellow color.

Common

How to confirm: Observe if the yellowing is starting specifically on the oldest, bottom-most leaves while new growth remains green.

Sunburn (Photo-oxidation)

While they love light, sudden exposure to intense, direct midday sun can scorch the fleshy leaves of Aloe brevifolia, turning parts of the tissue yellow or white.

Common

1 Immediately move the plant to a location with bright, indirect sunlight to prevent further tissue damage from direct UV rays.

2 Monitor the soil moisture levels using a moisture meter to ensure the plant is not also experiencing heat stress from drying out.

3 Avoid applying high-intensity fertilizers while the plant is recovering from sun damage, as this can increase physiological stress.

warning

Temperature Stress

Exposure to temperatures below 50°F (10°C) can cause physiological stress in this species, resulting in a loss of pigment and yellowing leaves.

Common

1 Move your Aloe brevifolia to a warmer location, ensuring it is protected from drafts and temperatures consistently above 50°F (10°C).

2 Monitor the soil moisture levels closely, as temperature fluctuations can alter evaporation rates; use a moisture meter to prevent overwatering during cooler periods.
