While we are still collecting data on frost protection, we have heard many success stories from growers who reported a noticeable temperature difference inside their Tree Defenders compared to uncovered trees and plants nearby. Many covered trees and plants came through frost events in great shape while unprotected ones did not. See one grower's firsthand experience on our Instagram showing their Tree Defender covered tree thriving after a frost event.
