It got warm super fast this year. Not counting the false starts in February and early March, we went from cold and snowy at the beginning of April to too hot to live a little over a week later. So all the plants are in fast-forward—at least, the ones that didn't ruin their chances this year by starting off too early and getting frozen when the cold came back.
I'm always interested in the transition from winter to spring, as the green comes back. You notice it in the trees, as the bare sticks start to grow green and yellow fuzz before filling in with baby leaves—it's not just the color that changes, it's the shape of the skyline. The grass is more subtle, and more interesting to me. At one point the grass is grayish-yellow; later it's deep dark green. You can't see it happen. One year I want to do a photo project, and take a picture of our yard from the same angle every day so I can put the images together and finally see the greening in action. The only problem is I won't be able to know exactly when to start the project. When does the grass start greening? You never know until it's about done; that's when you finally notice anything's happening.
The grass is in a hurry too this year. It's definitely green now, and starting to grow. The chickens are loving it, and doing their best to keep it short. The improved diet shows up in their eggs, which are noticeably yellower of yolk than they were last month. Yup, we all love the warm and the green—and we appreciate it all the more for having missed it in the winter. I love having seasons.
