Pistachio growers are eager for springtime to arrive, and warm weather on the horizon means dormancy is almost over.
“Pistachios need a certain amount of heat to push buds and begin flower development. Once this begins to happen, the tree is no longer an ectoderm, it’s end of the season can begin with the initiation of flowering and bloom. Trees, of course, plants are not warm-blooded like us. They’re really dependent on the air temperature and soil temps, so the speed at which they metabolize, the speed at which they begin plant development in the spring depends on the warmth: how warm or cold it is,” said Craig Kallensen.
There has also been talk that carbohydrates in the tree can trigger bloom. Kallensen tells aginfo.net that is a myth.
