transitions → repotting-and-transplant-shock
Repotting and transplanting are necessary operations — but they are also major stress events.
Even when done carefully, they disrupt root function and create a temporary mismatch between supply and demand.
This is known as transplant shock.
Transplant shock is not caused by “disturbance” alone.
It results from: - Loss of functional root tips - Root–soil contact disruption - Changed oxygen and moisture conditions - Altered microbial environment - Sudden changes in water and nutrient availability
Roots must re-establish before normal uptake resumes.
After transplanting: - Leaf area remains unchanged - Transpiration demand stays high - Root uptake capacity is reduced
This imbalance causes: - Wilting - Growth stall - Nutrient deficiency symptoms - Increased disease susceptibility
Above-ground symptoms lag behind root disruption.
Recovery depends on: - Speed of new root growth - Root-zone temperature - Oxygen availability - Moisture stability - Stress load after transplanting
Recovery is a process, not an event.
Overwatering after transplanting: - Reduces oxygen - Slows root regeneration - Encourages root disease
Roots need moisture and oxygen to recover.
Transplant shock is amplified by: - Heat stress - High VPD - Salinity - Poor drainage - Disease pressure
Stacking stress during recovery leads to lasting yield loss.
Best practice focuses on:
Key mistake: - Treating transplanting as a neutral event
Transplants need recovery, not performance.
