The lettuce in growing well. Take a look at the previous post and see how much they've grown in just three weeks. I can tell I disturbed the seeds by watering soon after they were planted, because the square is not evenly covered with lettuce plants. I'm looking forward to the day when I can take my scissors and fill the salad bowl.
The spinach is becoming recognizable. I think everything has slowed down some now that the days are getting shorter and the nights are cooler.
Can you see the onion sprouts? They're so tiny. They will become red and green scallions.
The mesclun is growing. I can start to see the different kinds of lettuce.
These are the sugar snap peas, the biggest plants in garden so far. They're supposed to grow to vines five feet tall, so I'm going to have come up with some kind of a support pretty soon. I may use an old tomato cage.
I planted some more seeds. I couldn't find collards, turnips or kale here, so I ordered these seeds from Territorial Seeds in Cottage Grove OR (a blast from the past!). 
I thinned the radishes last weekend by pulling out the extra sprouts. I decided to save and eat the extras. I put them in a salad, but I couldn't taste them at all. Oh, well.
The radishes sprouted first, on Friday, in just 5 days. These are Easter Egg Radishes from Renee's Garden in Felton CA. They're supposed to be white, pink, red or purple. I bought a lot of seeds from Renee's Garden, thinking that because it's nearby, the plants should do well here. I can see why they say radishes are good to grow for kids. It's very satisfying to see them sprout so soon. 
This is the mesclun--baby salad greens. I'm looking forward to a whole square foot full of little lettuce leaves of different kinds.
We put the grid across the top of the garden box to make it an official square foot garden. The squares look awfully small. It will be interesting to see how much food I actually get from it.
Planting peas. I just used my finger to poke holes in the soil. It feels like sticking my finger into a really dense, moist chocolate cake! (In fact, I've been craving cake ever since I planted.)
My dh built this cage to protect the garden, especially from the cat (who might think it's a giant dirt box just for him). I can also drape shade cloth over it if the weather gets hot again.
Detail of the garden cage. It's made of pvc pipe and mesh. The whole thing lifts easily off the garden box.
I cut weed cloth to fit the box, then positioned it and set the box on top of it. I decided to center it against the edge of the patio, because I can see my new box from my kitchen window. That way I hope I'll remember to keep it watered.
Now it's time to mix up the potting soil. The method described in The All New Square Foot Garden worked really well. I was able to handle 8 cubic feet of soil myself. (Although my should does hurt a little now!) I spread out a big tarp and poured out my three kinds of compost and mixed it together with a shovel.
Then I added the vermiculite. The mixing method is to fold over the tarp and pull it so the soil rolls over itself. Then walk around to the next edge of the tarp and repeat till it's well mixed. This picture is the mixed compost and vermiculite.
Next I added the peat moss and mixed by folding and pulling the tarp. 
Then I pulled the tarp up to the edge of the box and dumped the soil in to fill it up one third of the way. Next I thoroughly wetted the soil, and then continued to add layers. The whole process took me about one and a half hours to mix the soil and add it to the box.
Here's the finished 4 foot by 4 foot by 6 inch box, filled with soil. My calculations were good and the box is filled just to the top. Amazing!
