I planted two reliance peach cultivars this spring and they grew exceptionally well here in Western WA. Up until this last week their leaves looked like they did in summer. This past week we have had freezing temperatures as low as 15 F. Now about a third of the leaves look brownish but the rest look great. The rest of our fruit trees have long since lost their leaves. I am afraid that they should not look this way and should be sleeping. Is there anything that I should know or be doing.
