Transplant shock
Last reviewed 2026-10-04
Transplant shock is the stress a plant experiences after being moved from one growing place to another. Disturbed roots may temporarily absorb less water, while the plant loses water from its leaves. Wilting, stalled growth, or leaf drop can follow, especially when the move happens during heat, wind, bright sun, or dry soil.
What it means
Transplant shock is a response to root disturbance and changed conditions. It is not one disease. A plant may recover as new roots establish, but severe damage, poor timing, or continued water stress can kill it.
How it affects the garden
Handle seedlings by the leaves or root ball rather than the stem. Water the planting hole and the root zone, settle the soil without compacting it, and protect the plant from harsh conditions while it adjusts. Hardening off helps indoor seedlings adapt to outdoor light and wind before transplanting. Avoid moving a plant when the root ball will crumble or when the weather is unusually hot and dry.
The seed starting calculator helps plan an indoor start, but the transplant date should also account for plant size and current weather. Direct sowing avoids transplant shock for crops that tolerate it.
Example
A tomato seedling wilts for a day after planting in the garden, then resumes upright growth after its roots remain moist and the plant receives temporary protection from afternoon sun. That pattern can be normal adjustment, provided the stem and roots remain healthy.
Common confusion
Transplant shock can resemble drought or root disease. Check soil moisture, stem condition, and roots before assuming the cause.
