Water Stress (Underwatering or Overwatering)

Pak Choi has a high water content and shallow root system, making it highly sensitive to soil moisture fluctuations. Drought causes loss of turgor pressure, while waterlogged soil suffocates roots, leading to wilting.

Very Common

How to confirm: Stick your finger 2cm into the soil; if it is bone dry or extremely muddy/clumped, you have a moisture issue.

2 If the soil is bone dry, water the plant thoroughly until water drains from the bottom; if the soil is saturated, allow it to dry out before watering again.

Transplant Shock

Recently moved Pak Choi seedlings often struggle to establish roots in new soil, leading to temporary drooping as the plant fails to uptake water efficiently.

Very Common

How to confirm: Check if the drooping started within 24-48 hours of moving the plant to a new pot or garden bed.

1 Minimize further stress by keeping the plant in a stable, shaded environment and avoid direct, intense sunlight until the drooping subsides.

2 Apply a liquid microbial inoculant to the root zone to stimulate rapid root development and help the plant establish itself in the new medium.

Root Rot (Pythium or Phytophthora)

Excessive moisture in Brassica crops promotes fungal pathogens that decay the root system, preventing the plant from supporting its heavy, fleshy leaves.

Common

How to confirm: Gently lift the plant to inspect if the roots are dark brown and slimy rather than white and firm.

1 Immediately inspect the root system for mushy, brown, or foul-smelling roots and prune away any decayed tissue using sterilized tools.

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

3 Monitor soil moisture levels closely with a meter to ensure the substrate is allowed to dry out between waterings, preventing the excessive moisture that fuels fungal growth.
