Re: Signs of spring :

Ken , the dead looking palm is my Washintonia filibusta . It's about 10 years in the ground . If I see anything below 16F I protect the trunk only . It'll put out 25 fronds in a season so as long as the trunk and spear area is OK the palm will look respectable to great from about May till January most years . That's about 8 months of looking respectable to great most years , but the exceptionally cold shot in November turned the fronds ugly earlier than usual last fall . The trunk , as I mentioned is hardy to at least 16F , but the fronds are only hardy to 23F with some damage at 23F .
I think my low too has been only 20F , so I haven't needed to protect the trunk so far this winter . In the winters that are mild like this one I'll leave the dead fronds on the palm and the dead fronds will become a skirt .
Right now there are small areas of the fronds near the petioles that are still green and the petioles are also green , as well as a partially green new frond emerging out now .
Here's a picture taken yesterday of the green petioles and one mostly green frond :
Ten year lows: 15F 19F 20F 5F 4F 15F 7F 8F 14F 19F(2020)
