Abiotic
If a plant is said to have an abiotic problem, it is not being affected by something living like pests, fungi, bacteria or viruses. Common factors causing abiotic injuries include water, sun, temperature, wind, soil, chemicals, contact and nutrients.
For example, two branches can cross on a tree. If one branch moves, it may start rubbing away at the other branch and cause a wound. This can be corrected by pruning away the damaged branch, which will prevent further problems.
Many of these problems can happen at each end of their respective spectrums. Some trees and shrubs cannot handle wet feet (a common name for the condition when the soil is continuously wet, as can happen with clay soils) and may languish or die. Many others will not survive in bouts of drought.
Correcting an abiotic disorder means removing the stresses as possible (like the colliding tree branches) or protecting the tree or shrub as best you can.
