While we posted this episode all the way back in 2018, we thought we would dust it off since the information is still timely.

Phoebe interviews Craig Kallsen, the now emeritus subtropical and pistachio tree crop advisor for Kern County, to talk about what we know and don’t know about dormancy in pistachios. Craig also talks about a paper he published back in 2017, looking at the correlation between winter and spring temperatures and current season’s yield. This is an ongoing area for research and there are still more questions than we have answers.

This episode is a direct followup to “Chill with Dr. Katherine Jarvis-Shean”, and while you don’t need to listen to Katherine’s episode before you listen to this one, if you aren’t familiar with dormancy and the different chill models, we suggest you listen to that one before this one.

Pistachios are very salt tolerant, at least compared to most of the other orchard crops that are grown in California. However, this does not make them immune to the effects of salinity. Daniele Zaccaria recently wrapped up a four year study examining the water use of trees under varying levels of soil salinity and found that water use decreases as soil salinity increases. This has major implications for tree health and water use post SGMA. Listen to find out more.
