Looking good!
We're in the middle of building our garden, too... we're a bit "late," as well. Do keep on top of the weeds, though.
As for flowers, I am told that both Marigolds and Nasturtiums are really good planting companions; we're planning to add some to our beds, or to the edges of beds.
All the best to you and Bright Blessings!
