Complete Guide to Overwintering Caudex Plants

Many caudex plants (caudiciform plants) have adapted to go dormant during their native dry seasons. Overwintering is the greatest challenge in caudex cultivation in temperate climates, but proper management makes it entirely manageable.

Why Winter Care Matters for Caudex Plants

Most caudex plants originate from Africa, Madagascar, and Central/South America, and are not adapted to cold winters.

• Minimum temperature: Most species need above 5 degrees C (above 10 degrees C is ideal)
• Frost warning: Frost exposure is fatal for many species
• Winter humidity is also dangerous: Watch for root rot during dormancy

When to Bring Plants Indoors

Summer-Growing Species (Pachypodium, Adenium, etc.) - **Move indoors**: Before overnight lows drop below 15 degrees C (typically early to mid-October) - **Location**: Bright indoor spot (south-facing window) - **Heating**: Maintain minimum 10 degrees C

Winter-Growing Species (Cape bulbs, etc.) - **Active in winter**: These species actually grow during cold months - **Dormant in summer**: Require water withholding and shade protection in summer

Dormancy Period Watering

Overwatering during winter is the leading cause of root rot.

• After leaf drop, reduce to minimal watering: Monthly at most, adjusted by species and conditions
• Wait until soil is completely dry: Even then, waiting an additional 1-2 weeks is acceptable
• Water on sunny mornings: Avoid afternoon watering to prevent moisture buildup
• Skip watering on cold days: Don't water when temperatures are below 10 degrees C

Identifying Normal vs. Abnormal Leaf Drop

Pachypodium and similar species drop leaves in winter.

• Normal leaf drop: Leaves gradually yellow and fall naturally
• Abnormal leaf drop: Sudden mass leaf drop or blackening indicates possible root rot
• Diagnosis: Lift the pot - if light, soil is dry; if heavy, root rot is possible

Supplemental Heating Equipment

• Heat mats: Warm roots from beneath the pot
• Greenhouses/poly tunnels: Efficient for large collections
• Grow lights: Supplement insufficient daylight
