Temps needed

[SDdave]

The silver maples have flowered. We are expecting low teens the next few overnights with day highs of low 30's. Is that cold enough to freeze off the flowers, pushing back budding stage? Or am I totally S.O.L. with no paddle?

My silvers flowered on the 20th. Test boiled some sap collected today from a small run. Still makes great syrup. Should flow well tomorrow and we'll see what we get. All the flowers are now clearly brown in color from the good freeze.

We had several days of 60+ temps before and after they opened, but no sap flow. Had two evenings of temps near 20.
