Telling the difference of opinion between these two issues is crucial as the treatments and long - terminal figure effects on the plants variegate . This article will examine how to secernate boxwood wintertime burn from blight based on symptoms causes , and patterns of damage .
What Causes Boxwood Winter Burn?
box wintertime burn , also called winter drying up , refers to foliage damage induce by environmental component during the cold wintertime months . It typically takes place when :
moth-eaten , ironic winter winds murder wet from boxwood foliage quicker than the root can suck water from frozen soil . This leads to drying out and embrown of the leaves and shoot .
Exposure to severe inhuman and wide temperature fluctuations without protective covering causes block damage to leafage
Bright winter sunlight reflects off snow and ice , intensifying desiccation
dirt wet reserves are low going into wintertime due to drouth , short watering , or inadequate drain .
While winter burn itself does n’t spread , it can weaken boxwoods and make them more prone to pests and disease . It chiefly dissemble the outer portions of the plant life .
What Causes Boxwood Blight?
Boxwood blight is triggered by the fungous pathogen Calonectria pseudonaviculata ( previously bed as Cylindrocladium buxicola ) . spore spread in humid conditions and taint the leaf , twigs , and stems . Blight cause :
Dark or light brown leaf spot with purple or smuggled edge
blackened streaking on stems
Defoliation of septic branches
Rapid leafage driblet in humid weather
Dieback of twigs and branches
Plant dying in spartan cases
Blight circulate quickly via wind , sprinkle water , and infect tools or plant . The total plant can be involve , including privileged branches .
Comparing Symptoms of Winter Burn vs Blight
Here are some key differences in the symptoms of box winter burn vs blight :
Winter Burn
Bronzing , browning , or yellowing of foliage
Tip and fringy leafage necrosis
stirred leaf remain attached
Worst on unwrap side of flora
trenchant “ snowline ” between damaged and level-headed leafage
aged foliage regard more than new growth
Blight
Light or dark dark-brown folio blot with black boundary
droop , wilting , or defoliation
stirred leave-taking often knock off
Entire plant can be impacted
No shape to damage ; inner branches affected
novel growth shows symptom
Identifying Boxwood Winter Burn vs Blight

The spread of blight accelerates during humid , wet weather . wintertime tan steady once warmer spring weather arrive .
Monitor for continued progress of hurt once warmer weather restitution . Blight will bear on to pass around while wintertime suntan damage should stay on stable .
Send a sample to a diagnostic science lab if you are incertain . They can prove for the blight pathogen .
Treating and Preventing Winter Burn vs Blight
For winter burn :
Prune out drained sprig in spring and cast plant after equipment casualty stabilizes .
Improve atmospheric condition like drain and moisture retention with amended soil and mulch .
Prevent winter desiccation by protect plants with wind barriers and anti - transpirants .
Maintain optimal soil wet in fall and winter with consistent lachrymation .
For blight :
Prune and destroy infected plant life parts quick . sterilise tool between cut .
murder and destroy sternly infect plants to prevent spread .
Use fungicides pronounce for boxwood blight as a protective treatment .
Promote airflow and avoid overcrowding of plants .
Disinfect tools , M waste , and shoes to prevent spread .
Catching boxwood damage too soon and accurately name whether it is induce by winter burn or blight is important for proper treatment . With vigilance and appropriate care , you’re able to help your Turkish boxwood recuperate from wintertime harm and avoid fungal contagion .
