Quick Fixes
Emergency unpotting
Remove plant immediately from wet soil. Speed is critical.
Root rinse
Rinse roots under lukewarm running water to remove all soil.
Aggressive pruning
Cut away ALL affected roots without hesitation. Its better to over-prune than leave infected tissue.
Peroxide treatment
Spray or dip roots in 3% hydrogen peroxide solution. This kills pathogens and oxygenates tissue.
Quick dry
Pat roots with paper towels and let air dry for 30-60 minutes.
Fast repot
Repot in completely dry, fresh potting mix. Do not water for 3-5 days.
Stress reduction
Place in bright indirect light, away from direct sun. Reduce watering frequency significantly.
Organic Treatment
Remove and assess
Carefully remove the plant from its pot and gently wash away all soil from the roots. Assess the extent of root damage.
Prune affected roots
Using sterile scissors, cut away all soft, mushy, brown, or black roots. Cut back to healthy white tissue.
Apply cinnamon
Dust all cut surfaces generously with cinnamon powder to prevent fungal regrowth.
Prepare chamomile soak
Brew strong chamomile tea and let it cool. Soak the remaining roots for 15-20 minutes.
Air dry roots
Let the roots air dry for 2-4 hours in a shaded area with good air circulation.
Prepare new container
Clean the pot with diluted vinegar, rinse well, and fill with fresh sterile potting mix.
Repot carefully
Plant in the new soil, ensuring the root crown is at the proper level.
Initial watering
Water lightly with diluted neem oil solution (1 tsp per liter of water).
Recovery monitoring
Keep soil mostly dry for 1-2 weeks. Only water when top 2 inches are completely dry.

ðą How to Care for Pequi Tree to Prevent Root Rot?
ð§ How to Water
Water regularly during the first year of establishment, especially in the hottest months. Once established, the tree is highly drought-tolerant and can survive on natural rainfall. Avoid waterlogged soil as the Pequi Tree does not tolerate root flooding.
âïļ Lighting
Plant in full sun, without shade. The Pequi Tree needs at least 8 hours of direct sunlight per day to thrive and produce fruit. In partial shade, growth is impaired and fruit production significantly reduced.
ðŠī Ideal Soil
Prefers sandy to loamy, well-drained soils with slightly acidic pH between 5.0 and 6.5, typical of the Cerrado. Tolerates nutrient-poor soils rich in aluminium and iron. Avoid heavy clay or compacted soils that retain excess water.
