The new growth has not 'hardened off' by winter's arrival, and ice crystals can form inside cells and between cell walls. Freeze damage is common on the southwest side of trees because afternoon sun is responsible for significant changes between day and night temperatures. Stem breakage relates to ice or snow accumulation. This is more of a problem in north and central Louisiana. Avoid poorly drained soil areas.
Soil water can freeze and lift plants out of the ground.
Select plants adapted to our climate - USDA Hardiness Zones 8 and 9. Prune and fertilize properly to minimize new growth in the late fall and winter. Plant new trees and shrubs where they will be protected from intense winter sun and drying winds. Maintain adequate moisture in plant tissue. Mulch landscape beds to insulate the root system and minimize soil temperature fluctuations.
