I have a very large Oak in my front yard. Last fall I collected about 35 acorns, set them in a tub of water, and bagged and refrigerated the sinkers. Only two didn't fail from mold in my refrigerator where they sat for three months! Stratification is booooring. Anyway the two survivors started off with very promising vibes. But, for the past month, I have seen no growth. The leaves were scorched when they spent a day outside. Could that be the cause of the pause? Thanks for your invaluable opinings.
