Water Stress (Inconsistent Watering)

Both underwatering and overwatering cause leaf drop in Firefall Orange. Dry soil causes leaves to wilt and drop, while waterlogged soil leads to root hypoxia and subsequent leaf shedding.

3 Ensure the plant is in a container with excellent drainage and consider adding perlite to the soil to improve aeration and prevent future waterlogging.

Root Rot (Phytophthora spp.)

Excessive moisture in the potting medium allows fungal pathogens to attack the root system, preventing water uptake and causing the plant to shed leaves as it struggles to survive.

Common

How to confirm: Gently lift the plant from its pot to inspect if the roots are dark, slimy, or emit a foul odor.

1 Immediately inspect the roots for mushy, dark, or foul-smelling decay and prune away any dead sections using sterilized tools.

2 Repot the plant in a fresh, well-draining medium and incorporate perlite to improve aeration and prevent future waterlogging.

3 Switch to a pot with superior drainage and use a moisture meter to ensure you only water when the top inch of soil is dry.

Pest Infestation (Spider Mites)

Two-spotted spider mites feed on the sap of Hibiscus leaves, causing them to yellow and eventually drop. Large populations can cause rapid defoliation during hot, dry periods.

Common
