With this winters severe extremes, one wonders how our plants are surviving and if they have sustained damage. I’ve already seen Rhododendrons with ‘winter burn’ on their leaves.
One of our bigger expense is heating oil in March/April as we must maintain 68 degrees-plus for the young, sensitive plants. However, when the sun is out, the greenhouses can reach temps of 90 to 100 degrees F and, you guessed it, we have to turn on the big venting fans to cool the plants down. Does this cycle make any sense at all????
