This has been one of the stranger weeks! One day, it was 70s degrees during the daytime, and it went right to freezing that night. Look! What happened! 
I did take the opportunity to clean up the weeds when it was nice and warm. Now, the ground is ready. 
I did not til the soil because I did not want to disturb anything underneath. However, I did see a few soil centipedes coming out when I was cleaning up. It is a good sight that the soil is still rich and I have helpers for some Bio-Pest Control.
When I was taking a break, I saw a welcoming visitor! Yes, the American Robin was searching for worms where I was cleaning the weeds. He was so happy, stomping on the soils and trying to get his worms.
Well sadly, the next day, we had the ice storm. Yes, it was not a normal snow storm. We had Winter Advisory ice storm! 
He was very disappointed that someone stole his Summer away.
One interesting aspect, throughout my observation, I usually saw American Robins in my front yard, he/it rarely came to the back. American Robins do not feed at the bird feeders, their primary food are worms and berries. However, since I cleaned up the area in preparing the garden, he started coming to the backyard. Maybe he saw the soil and knew that there would be worms!
Well, I did put down a few sunflower seeds under the sheets of cardboard.

I did not clean up the weeds underneath. The primary purpose is to protect the sunflower seeds. I am not sure if the freezing weather would do any harm. Hopefully not, but I knew that our last Spring frost is around mid-April, so I am pushing it. However, I grew some sunflowers around the same spot the previous year, so I know that this area is perfectly fine for sunflowers and receives full sun during the Summertime. We will see 🙂
This coming week “supposedly” will be better. I am heading to my local garden and see what they have. I may get some flowers and nurse them in my basements until the proper temperature is here. I am not even sure if they have any flowers now. But this is supposed to be Spring Break! What happened? 🙂
