I am outside several times a day. I have always done live heading at the end of the day. When I just had a few Stella's and Happy Returns daylilies and my iris's (the lilies take a few days longer). A habit I really have to watch now that I have started hybridizing! When I read the first part of your post, it made me want to go back out side
.
I like to go out when the light has just started to fade and walk around alone to enjoy the days blooms and growth once more. It is my time alone with the garden, in the coming night air and sounds. I also have a small pond and enjoy the water and plants in the evening. I would not trade that time of the day for anything. It is my time to rejoice in the beauty of my labor!
