The date your trees will begin budding depends on a variety of factors. Factors which effect a tree’s budding cycle include temperature, location and tree type. You can tell a tree is about to bud when weather becomes consistently warmer, and the days longer. As nights shorten, the changing levels of the photoreceptor phytochrome triggers the trees to bloom.
