The number of chill hours in your area will determine if the nectarine tree will do well. I included a fact sheet that shows the number of chill hours for San Diego. You may not get enough chill hours depending on where you are. Panamint needs about 250 chill hours. You may want to call your local university extension office or a local nursery for their recommendation.
