Very Common

Root Rot (Overwatering)

Excessive moisture in heavy soil deprives roots of oxygen, leading to fungal pathogens like Phytophthora that destroy the plant's ability to transport water upward.

Temperature Extremes/Heat Stress

High ambient temperatures increase transpiration rates beyond the lemon mint's ability to uptake water, causing temporary wilting during the hottest part of the day.

Common

How to confirm: Observe if the drooping occurs primarily in midday sun and if the plant perks up during cooler evening hours.

1 Move your Lemon Mint to a cooler location or provide afternoon shade to reduce transpiration and protect the plant from direct heat.

2 Monitor soil moisture levels closely to ensure the plant remains hydrated during heat waves, using a moisture meter to prevent dehydration.
