Periods of extended warm weather in early Spring which encourages the garden to begin to grow and bloom is always a concern to me. I know there is always a threat of a low enough night frost to damage the growing buds and destroy an entire season of flowers or fruit.
The Asian Magnolias were in full bloom when the temps dipped to about 25f a few nights ago. The flowers do not look so good now.
This winter has been entirely unseasonably warm. The Basjoo bananas have only had their leaves killed by frost as the trunks seem to be standing tall. In fact, new leaves have grown out the tops.
Hopefully if was the last hard frost as the maples and many other plants also are in the process of blooming or growing leaves.
