8 Effective Ways to Protect Plants From Frost

Plants react differently to changing climatic conditions. Temperature changes affect the growth, flowering, and subsequent fruition of plants. Although a measured dose of sunlight is needed to maintain growth and generate energy for metabolic activities, a scorching summer climate can induce sundry damages and stunt plant growth. Also, frigid temperatures below freezing, characterized by melting blocks of ice, can damage your plant.
