There was a 21º F (-6º C) frost 3 weeks ago,

Today I took some fotos of the damage to some of our planted species:

21º F  Ouch!

It usually takes a week to show damage, how long ago was the cold?
How many hours was the cold? I have many of the same species I even got some seeds from you,
it's good to see they can handle these temps. Stay warm!

It was 3 weeks ago, I dont know how many ours of frosts (but there was another -1ºC frost the next day)... and yes, I am very happy indeed!
