Photograph 1: May 1 — "The Cool Garden Wakes Up"

Mostly bare earth with islands of green. A promise. Cover crop on beds 10 and 13. Radish gap crops on 7-9 while tomato trays harden off on the porch. You can still see the bones of the bed layout. Smells like cold soil and fresh growth.

Photograph 2: June 1 — "Everything Is In the Ground"

Two weeks past frost-free. Every bed has something growing. Cool crops hitting stride. Warm crops small but visible.

Photograph 3: July 1 — "The Garden Is Loud"

Peak. Everything producing or about to. This is the portfolio photograph. Almost overgrown, alive, abundant.

The garden feels bigger than it is. Tomato beds are green walls with first color breaking through. Kale stands like sentinels. Squash creeps into paths. Basil and oregano perfume the air. Sweet potato vines on bed 1, potato flowers on bed 4. The bean bed tells the whole succession story in one glance. Buckwheat just sown on beds 10, 13 -- the quiet reset. This is the photograph.

Photograph 4: August 15 — "The Turn"

The garden is shifting. Peak harvest but season bending toward fall. Determinates finishing. Disease-prevention pruning visible. Already thinking garlic and cover crops.

August tiredness. Still abundant -- peppers peaking, tomatoes ripening daily, beans coming -- but you can see the end. Sweet potato vines lush on bed 1, potato harvest approaching on bed 4. Fall crops going into freed beds 11 and 12. Buckwheat mowed on 10 and 13. Not sad, strategic. The cool-season comeback is starting in bed 2. The garden is turning a corner.
